Hi efficient speaker, bass problems

Duke, some of us are not so enamored with the sound of most loudspeakers with ported bass.

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. :-)Dan_ed

Dan,
Precisely what i had suggested , multiple drivers is the way to go IMO, i have no doubt in what you have described, have fun ...

Hi Unsound,
Its all perception my friend.
I think of low as 82 to 86
mid as 87 to 91
mid-high as 92 to 94
high as 95 + -Timlub

I would be in agreement here and efficiency mean different things to different topologies, a linesource for eg, 88 db would be very efficient IMO with a linesource after factoring the typical 9-12ft listening distance .

Duke , it does seem to me that you are discussing speakers designed for corner placement, if not how would this apply when speakers are setup and voiced away from the walls.

regards,

Wesixas, we may be splitting hairs here, but, I agree even more with your criterion. Of course the impedance will have to be figured in as well.
