Hi efficient speaker, bass problems

OK tim ...

Weseixas, you wrote:

no one driver is going to go from 30-500+ hz IMO and still produce high sensitivity it would also produce 2 much distortion IMO.

I guess I take issue with this. The TAD driver I mentioned does exactly this range quite easily, and does do at 97 db. Yet it is quite fast and transparent.

But more recently I have heard some field-coil powered 15" drivers that are even faster and more transparent, and cover the same range yet are more like 98 or 99 db (without a horn). It is used in a speaker that got 'Best Sound at Show' in TAS' CES issue a couple of years ago.

Interesting and thanks for the info and response

Regards,

Wes, absolutely! :-)

The Aerials use a 10" woofer, and that damn port. The midbass has a 15" driver and the bass uses an 18" driver.

I understand that field coil works the best down on the low side. Some say it is the best bass possible. I haven't been fortunate to hear this yet, but I've heard that it is fast, dynamic, and detailed. And way above my paycheck. :-)

Would be nice if the poster new what hi eff means and its not 91db or 94db designs. So the threads title is wrong poster has not heard bass problems in Hi eff just a improper system match with a moderately efficient design. So to me the whole premise of this thread is wrong.
