So I finally had a day to give the hst-12 a good listening.
I am impressed to say the least. I can't say that I know much about subwoofers or the fancy terms or words to describe them but this woofer sounds amazing...
With the hst-12 it is like a whole new day! The sub is un-intrusive and just disappears into the stage.

I've bought these from Nick at Stereo Integrity a while back and I finally got a chance to get them installed. They have been installed for about a week so far and I wanted to give my initial impressions.

I have them installed in a 2006 Ford Fusion. The M25 tweeters are installed in the factory sail panel locations and the TM65 MK2's are installed in the factory lower door area with HDPE adapters I made myself. Unfortunately I don't have any pictures of the install but it's all in factory locations and stealth like I was wanting. The HPF on the mids is set to 63hz and the LPF is set to 3200hz. The tweeters are high passed at 3200hz as well. All crossovers are 24db/octave.

Let me first of all say I have been in and out of car audio for a number of years but I am far from an audiophile but I just enjoy music. This is my first time ever having an active front stage though. The M25 tweeters made extremely well. I like the plain black look and have plenty long attached speaker leads. The TM65's are a beautiful set of speakers with heavy duty spring loaded terminals. The slim depth makes them easy to install and I really like the look of the S surround. Once again no logo just a attractive black cone.

I have listened a number of tracks so far and have been blown away with how they sound together and blend with my sub. The tweeter is very smooth and easy to listen to. I have been able to listen to them for a long time without ear fatigue like used to get with the Pioneers. I haven't noticed any hints of distortion with them unless it is in the music itself. I'm really impressed how natural they sound(don't know a better way to describe them) at reproducing any type of music I have thrown at them.

The TM65MK2's are just as impressive or more impressive than the tweeters. These things can play really low and still stay controlled. I didn't want to try playing them lower than 63hz but I know people do with no problem. The midrange is just as outstanding as the midbass. Even playing up to 3200hz I haven't heard any distress from them. They can play plenty loud like the tweeters and blend with my sub effortlessly.

I haven't done much equalization with them yet either because my head unit is very limited but I do plan to add a dsp soon. But even still I think the imaging and sound stage is very good. Definitely better than any setup I have had. I couldn't be happier with these speakers and I think Nick has made a tremendous product at a very reasonable price. I tend to find myself smiling while driving at times listening to some of my favorite music almost like it's the first time because it sounds so much better.

I know this isn't a detailed review like some people have given but it's my first time doing one. If anyone has questions I will try to answer them as best I can.

Thanks again to Nick for making such a great product that doesn't break the bank but sure sounds like it does!

I was super impressed with the 6.5" mkII. Wow. If I was starting from scratch these are the go to mids. I can't believe they went so deep without effecting midrange. That was amazing. Since I'm a fan of kick panels, I can't imagine a better speaker at a better price point for the job. The tweeters were fantastic too!! What an amazing match set.

Thanks for the seat time Nick...your work is extremely understated. I think if all your transactions could take place in person, you'd sell out in a week.

Hi Nick-

Installed the TM 65's today with a set of FAST rings - I am very impressed! Definite improvement in extension and accuracy over the JL ZR650's I had in the doors. I have them playing 360hz to 63hz right now, but will tune after they break in.

Thanks so much, keep up the great work!

I received my speakers this past week and Friday had the chance to install and switch out from the V1.

Overall I am very happy with the improvements over the V1. I kept the same target curve and tuned the speakers the same way as the last gen and I have them crossed at 2500 24db slopes with M25 tweeters.

The three pluses that stand out to me most are the speakers ability to blend better with the tweeters. A more defined and detailed mid range and an overall "tighter" sounding front stage, this might have to do with my first plus though.

So, My house is an incredibly busy place and it took until today to get the house to myself. So naturally, I turned it up some. Even just playing fee air I an constantly amazed at these beasts [two HS-24 mkII]. The way they blend with the mains is just incredible. I'm listening to Booksmart Devil by the Silversun Pickups right now and it's like magic. The song that really put my jaw to the floor was Western Movies by The Olympics. The way these subs reproduce this dumb song is so wonderful. I ripped it from vinyl several years ago and it's always been kinda lifeless, until tonight.

When you are tire of being obnoxious, and are ready for a grown up system, the hst18mkll is the way to go. Smooth and articulate, and down to business. Well worth the wait. My only regret is that I don't have the room to run it ported. Great product, better customer service. I don't think that I have ever dealt with the owner of the company from where I purchased from. Keep up the good work Nick. Thank you.

MAX SPL:
To be honest, that is dissapointing.. I didn’t expect this, but it is impossible to drive this system loud..
I underestimated how much fysical grip this sub system now has on the construction and everything in and around it.. trust me I’m used to sub-buzzing and rattling of doors in doorframes, windows, ceilings and all sorts of stuff lying around.. the labsubs on their own where more than capable of shaking the room.. but this is of another proportion.. the addition of the 4 HS24 twins LITTERALY take it from shaking the room to tearing it apart.. the ceiling is shaking so violently.. the plasterwork and paint upured on some seams.. that happened in a few seconds.. actually it took not more that 1 wormhole sequence of interstellar.. the +100Kg steel rolling shutter on the outside is rattling so violently you can hear it above the sub-rumble 2 bloks down.. all doors and windows in a 50 meter radius rattle (and not a little) that effects approx 6 neigbours… everyting even heavier stuff in my adjecent garage and the garages of the neigbours is moving and falling down…the shock came when I came back in from chekking the (like crazy) rattling of the rolling shutter and saw that the picture moved completely from the screen.. it was the powercable that kept the beamer from falling of the shelve…
I would say at 60% capacity… in panic I turned the system down.. and that was the point where I heard a neigbour calling.. a few seconds later 4 neighbours where outside.. previously (in my Labsub era) they could laugh with it… not anymore… this is no teenage bass-bragging it is what actually happened.. litteraly in one wormhole scene…

Later I realized that if the construcion elements are giving in.. how bad must this shaking have been fort he beamer and processor.. they survived this round, but I’m hesitant to try it again.. that is why I said it.. I cant drive this sytem loud.. it has to much grip..

Wow....

First things first, these are really heavy buggers!

Ok, the sound is amazing.... Its been rare occasion that I have had the chance to hear bass this clean sounding....

Deep.... Intense.... Visceral....

....I could go on.....

I started out with some free air play and they put those polk psw125's to shame.....

If you had never heard anything but the polks..... youd think you were done....but I put them in their boxes!

Ha ha ha.... This is wicked....

My neighbor lives about 60' away.... I can rattle his walls.... this is awesome!

... this is CLEAN BASS

Truly incredible!

I received the HT 24. Man it's a beast! Finally got my infinite baffle enclosure built and mounted the 24". Initial listening tests are very impressive. The music now has a realistic sense of weight and dynamics. I always new I was missing something in my previous audiophile systems. SCALE! Now I have it. The feel and sense of the music. I have not even started to fine tune my system with any crossover points. I am just running everything straight with natural roll off high and low. I will NOT need any EQ, but will experiment will low pass crossovers around 70 HZ or so, but the HT 24" has good output well above that into the upper bass and midrange also, so I have some flexibility to fine tune for sure. I am very glad I decided to buy this from you. It puts all other bass I have heard to shame. No comparison at all. Horn loaded, ported, sealed, whatever, NOT EVEN CLOSE! I heard mega buck systems that are well into the thousands that can not approach the sense of scale and dynamics that I now have. REAL BASS. CLEAN AND NOT COMPRESSED. More like the real thing. Well I can't say enough really, but one thing I have noticed is that I catch myself smiling like a kid when I now listen to PINK FLOYD. It's all about the music, and enjoying the experience and I definitely am now. Again, Thank you Nick for your help and for making this HT 24". It's just what I have been missing. Gotta go and listen more!

I finally had some free time the past couple days to build a box and get these subs in my truck (2 BM mkIII's). They are in a 50" long by 4.2" tall box under the rear seat in a downfiring configuration, split chambers at .46 cubic ft per sub stuffed with polyfill. Although I was stoked about the specs of the BM, I've always been a little skeptical of their actually performance. Even today putting them in the box, I was thinking to myself "no way are these going to play down into the lowest octaves in a box this tiny..." I was very wrong. After setting the gain on my Cadence iA7 and setting the crossover point, I took about an hour and a half listening session with the BM's. I previously was using a pair of Adire Koda 10" subwoofers. I was completely satisfied with the Kodas, but I must say that everything the Kodas did well the BM's do better.

I listened to a few of my reference discs, and immediately was blown away. The BM's blend right into the sound stage, impossible to localize until high volume when the seats in my truck start shaking. Blending them to my Seas w18nx midwoofers was extremely easy and they are a great combo. Listening to the Eagles Hell Freezes Over album was pretty awesome. The BM's do an excellent job distinguishing between the bass guitar and kickdrums, never missing a beat and no muddiness.

Next I listened to some harder rock, and ended up listening to Seether - "Fake It" twice. The first time was at a moderate listening level, and again the bass was right up front, kickdrums were very tight and the bass notes during the chorus were played with authority and clarity. The second time I listened to this song I turned it up quite loud and opened up the gain on the amp a bit (I have the gain knob under the steering wheel for easy access). Man, this gave me a big smile and a little chuckle. The BM's are loud. VERY loud. I was simply stunned at the output these shallow subs have in such little airspace. Even at very high volume, the BM's remained composed and under control...no distortion. Rob Dougan's "Clubbed to Death" off the matrix soundtrack has some really subsonic material and the BM's crank it out without a hiccup. They can play LOW. A lot of my friends have trucks with underseat setups similar to mine with shallow subwoofers (Rockfords, Pioneers, Kenwoods, JLs etc). None of these shallow drivers come close to the BM in both clarity and output.

Redacted   

I have a single BM under the seat in my Ridgeline. Ditto what was already written about the outstanding ability of these subs to blend with the front stage. Running mine off of a Zapco DC500.1. The BM blends better than the DIYMAR12 that I had ran previously. Kick drums are right up front, along with the bass guitar. Even thought I have ran my Dyn MW182's down to 45 Hz previously, I am not running them at 80 Hz, taking the stress off of them at high volumes. Everyone that has listened to my setup says they can not locate the sub at all. This sub is a real winner and a bargain. When you consider the tight spaces it will fit in, it is an absolute home run for car audio!

Redacted   

Ok, my favorite thing about this [BM mkIII] is it's flexibility, it has no problem complementing whatever music I'm listening to (hip-hop, punk, electronic, indie rock, folk, classic rock, cheesy 90's dance music, etc.) and whatever bass mood I'm in. Drop the level down a couple of notches and it simply disappears, all the bass stays upfront, doesn't overpower the mids/tweets while keeping nice impact and great detail. If I'm feeling delinquent and crank the sub level up to hit hard it does without complaint while staying clean and detailed. It's not a mega-spl monster but it has more than enough thump in a small hatchback. ...The box is only 0.36 cubes, for a 12! This sub has no right to sound as good as it does, as loud as it does. I mean this is criminal!

Redacted   

I used my traditional playlist of tracks to put the woofer through its paces - Eva Cassidy, the Eagles, Dave Matthews, Fleetwood Mac, Chris Izaak, John Williams. In particular, "The Chain" on Fleetwood's Rumours brought a big smile to my face The transient response, the individual attack of the notes, the blending to the front stage...it all was effortless. Same with Eva Cassidy's "Wade in the Water" and "Wayfaring Stranger". Both are tracks that have made some pretty high-profile subwoofers choke in my opinion, but this Mag handled it with aplomb..."Wade in the Water" has some really neat stuff halfway through it with a stand-up bass playing a 7 note walking line while a muted trumpet does its thing...like any good subwoofer, the Mag reproduced what was on the recording without drawing attention to itself. In retrospect I really wish I had some Mingus with me, I bet Mingus Ah Um would be amazing... It's not scared of the orchestra, either. Kettle drums on Williams' score for "Revenge of the Sith" were extremely accurate and extended very deep. If you're looking for a small, sealed-box woofer and realism is your number-one priority, I don't see how you could leave this driver off your list. Power-wise, it really doesn't need a lot of power to shine - I would say 500-600W is all you need to get it to perform admirably. Two thumbs way up.

After owning the [26 subs], and hearing just about every sub you could think of in other people's cars the SI 15" was the best sub I'd ever owned. Awesome sound quality (great accuracy, natural, blended VERY well with front stage, no bad peaks, good low end, good punch, sounds good with all music and doesn't need Eq'd to death). And my god did it get loud with 1000w, ported and sealed just got SOOOOOO loud. With 2000w its just a monster, I mean just crazy loud even sealed.

Redacted   

I find flaws everywhere else in the system but the subwoofer. Un-EQ?d it is the finest example of (to use a cliche' word) tonal accuracy I've heard to date...The unadulterated capacity to get obscenely loud, matched with tight, transient bass is simply too much to pass up if you're in the market for a "super-woofer". Thumbs up Nick, you did a heck of a job.

I received my 15" IS D2. I opened the box and WOW! That's about all I could say for about 10 minutes or so. I was so impressed with the basket and motor structure I decided to mount it basket out. Very nice piece of equipment. I must say I have never heard such accurate, but loud bass notes. I am powering it with a [1200 watt] amp in a 2.9 cubic foot sealed box. Thank you for such a quality product at a reasonable price!

As with my Claw, nothing you threw at it could phase its performance, only now, it was louder, not even near my normal listening levels. It took the fast kick drums low bass lines and everything in between and really reached another level

Redacted   

Let me tell you, I have never, ever heard New York Minute, Hotel California, or Life in the Fast Lane as accurate as I hear with the Mag. The Kick drum blended perfectly with the mid-bass making a perfect blend of beat and tap (if you record you kind of understand what I mean) (you can actually hear not only the Deep bass from the kick, but the tap from the kick pedal hitting and ringing on the head of the drum) IMO this make the perfect blend from Mid-bass to sub-bass. ...In all, I enjoy the extreme low end from this sub, it is more then able to shake my truck apart. It can make my back wall and window flex with only 500rms.

Redacted   

There is simply no comparison between these and the [other subs] in the punch category. These things completely annihilate the [other subs] in higher frequency reproduction in a box that doesn't exactly facilitate higher frequencies. It's... just... a whole lot better. ...The D2s sound much cleaner going from low to high, high to low, MUCH LESS SLOPPY. They keep up with double kick drums flawlessly.

Redacted   

These things are in fact retarded, I could feel the bass in my kidneys... I'm in a HUGE car with a trunk and they were still punching me in the back.... I've never had that to this degree in my car before...
300 WATTS EACH! I'm simply amazed, even though I knew they could do it, I'm still amazed!

Redacted   

You guys impress me with the quality of the products you produce. I have been in the car audio field for about 10 years now and
this is by far the best subwoofer I have ever heard.

Redacted   

After about 12 hours of playtime, all I can say is you a customer for life. Hands down best sub I have owned in 22 years of playing with car audio. I am beyond impressed, I stand here with my mouth gaping open. It does NOT matter what I throw at it, it sounds incredible.

Redacted   

This combination has proved to be AMAZING!! The sub sounds like it's coming out of the very center of the dash/windshield area!!! The biggest surprise about the Mag so far has been the ungodly amount of authority it has down low while still remaining "invisible.

Redacted   

As lots of you know, Disturbed loves the use of their dual kick drums and theirs seem to be tuned lower than most bands. So a sub ends up having to reproduce VERY rapid double kicks. There is a drum solo right around 3:30 of this track. The Mag reproduced everything perfectly. I don't even remember the DIYMA R12, which has been my reference sub for SQ, reproducing that solo as well.

Redacted   

This is a great sounding driver. Talk about bass up front...the kick drums literally sounded like they were coming from the speedometer in Zach's car (the speedo is somewhat in the center of the dash) and it blends very well. It sounded great on all kinds of music. I was beyond impressed.

Redacted   

On to the Mag. We listened to the Mag for about an hour and a half. I brought a few CD’s and he played a few selections to demonstrate certain characteristics. This is my first experience with a 12” subwoofer. I have only ever had single 10” subs in my vehicles. My misconception has been that 12’s are primarily for SPL – sloppy sounding – not for the sound quality application that I desire. I was very impressed by the overall sound – very quick, deep, and accurate.

Redacted   

Performance of the Mag was outstanding. The Mag sounds fantastic right out of the box with little or no tuning - a rare achievement. The low end sound was really smooth and soft but the Mag also played 100Hz and above very well.

Redacted   

Even though the sub is still breaking in, output was better than expected. The Mag will get very loud off lower wattage than most of us are used to, especially considering it is in a sealed enclosure. Sensitivity was exceptional and another added bonus.

Redacted   

In fact, I'll go out on a limb and say the SI Mag is the best all-around subwoofer I've ever used. I still love the DIYMA 12 but the Mag is a fantastic subwoofer without any (glaring) flaws and should fit just about anyone's need for a great sounding driver that also has great output in a small enclosure. Nick should be congratulated on a great product that really delivers. I liked this driver so much, I just bought another!
