They are currently underpowered, getting only 125watts apiece, but I'm still not sure if it'll be worth upgrading to the BM's, building a new enclosure, and getting my 550w Blade Grenade G5 amp fixed (probably around $900 altogether) if I won't be able to use a ported enclosure.
For my install, the sub is there to complement the SLS 8's in the doors of a '93F150 single cab pickup, so I really only need low end extension from 50hz on down. Is 550w bridged to a pair of sealed BM's going to offer that much improvement over the SQ10's?
I guess what I should do is get my amp fixed and see how the SQ10's do when they're properly powered, and reevaluate. I'm keeping my fingers crossed that the SQ10's are just underpowered, but something tells me I'll be back. 
So just to make sure I didn't misunderstand -- the new BM will not perform admirably in any ported enclosure?  |
Going two sq10's to two BM 12's is going to yield a gain of roughly 3 dB without taking into consideration the BM's ability to out-displace the eD 10's by a factor of 50% from what eD claims. Once you take the extra displacement into consideration along with the added surface area, you have a lot more potential for output.
But yes, you are correct in that the BM mkIII's will
NOT perform well in ported enclosures (if you port them, you completely void your warranty), as they are sealed
only subwoofers.
