Hi efficient speaker, bass problems

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 -Atmasphere

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.

Dan ed, perhaps I'm mistaken, but I was under the impression that field coil drivers usually have power limitations. I would guess that could be a problem with bass drivers.

JohnK, I don't know of an absolute criterion for "hi eff". FWIW, IMHO, 94 dB is starting to get into the fold.
