If you want to go pro and you like Eminence and you want to buy in Canada, contact Q components in Ontario.

No 'free lunch' though, the JBL has a much lower Le and 4x the power handling, ergo higher SQ and dynamic headroom. Still, for a HIFI/HT app, it should be more than adequate for all but the most hard-core bass connoisseurs, though two in parallel wired isobaric seems the best compromise overall if space is an issue and still > 2/3 cheaper.

I've been interested in these for sometime now, the price is right and they should be very sq oriented which is what I want the most.. The plan is to mount isobaric with one driver seeing 5 cubic feet, not looking for high spl just good clean accurate bass.. They could be a poor mans JBL I'm a hoping and I may build two units so 4 drivers in all... Dave

That may be the best option. 94db is pretty good, and that woofer plays low.

If he's really wanting a 97-99db woofer, then he's will lose deep bass. He won't get the deep subsonic boom of car stereo, but if would be much louder however. The Dayton 18" seems like a good balance between LOUD and the LOW BOOM he's looking for.

My answer :
you buy 99 dB PRO woofer with 150w RMS sub amp.
99dB drivers with the ability to do 20Hz DO NOT EXIST.

Poweramps are cheap.

Well, I'm fortunate I have no SO issues, and doubly so as we have the clever Tom Danley to give us tapped horns to get the same result, if only in a big box and with a narrow BW.

What if it was a BIG driver? A 4 or 5 ft driver with a big enough magnet may come close

Disney has drivers like that in one of their rides " Eartquake" or something like that, but even that is not that efficient; I think that this particular driver has a 15 or 16 inch voice coil and is so heavy that it has trouble moving. I'll search later and see if I can find details
