Fine fine fine...Mag v4 T/S's. ;)

***Electrodynamic*** · 07-25-2008, 05:57 PM

The following figures were taken with the coils in series:

Re: 3.9 Ohms
Le: 0.76 mH
Fs: 29 Hz
Vas: 75 liters
Sd: 490 cm^2
BL: 14.0
Qms: 4.0
Qes: .494
Qts: .44
SPL: 87.6
Mms: 135 g
Xmax: 16mm
Xsus: 22mm

These T/S's were taken off a fresh production run unit. With a little break-in (aka: an hour of use) the Fs will drop into the mid 20's. Have fun guys!

Will you post those specs after a little bit of break-in once they make it over here? Just curious.

to behonest i don't know what all of that means! and not to sound rude but could you explain it or send me to a web page which does a good job at explaining it? and feel free to delete this post if you want to.

i guess you have to start somewhere just i always start pretty low on the knowledge totem pole! lol. sorry

(and that was the first time I checked out SSA since SI left

umm i got ya! thanks!

gushybear · 07-26-2008, 10:50 PM

thats actually an awesome thread. i knew what alot meant, but i didn't know how they all affected the woofer and their enclosure. very interesting (basic) read. atleast now i'm not completely uninformed when it comes to these 800~ sums.

Awesome. Although WinISD did want to put this thing in ported box.... But WinISD has led me astray before, so I suppose 1ft^3 it is. Thanks for the specs either way.

***Electrodynamic*** · 07-28-2008, 10:39 AM

Yep, no problem.

Indeed - WinISD is going to call for a larger box, but we have auditioned it in very small enclosures and it sounds excellent
