Best High Efficiency Speakers for full bass tone


Any thoughts on a pair of high efficiency speakers to use with vintage tube amp/analog set up/ in a room that is 32' deep by 20' wide to get full bass tone?

Right now I have a pair of Klipsch Forte II that just don't deliver on the low end as well as they do in a smaller room.
Smaller room they sound fantastic.

What really works in these bigger rooms? Looking for something with better bass detail than a pair of extra subs rumbling 60 hz and under.

Anything from Avantgarde - EQ'd, active subs provide full-range extension and >100dB sensitivity (up to 109dB, depending on model) and will fill a big room with modest tube power. Some very reasonably priced pairs of Unos and Duos on the 'Gon now.
Dear Astralography: ++++ " full bass tone.....better bass detail .... " ++++

two desired bass management characteristics that are really dificult to achieve.

Good audio system/room bass management IMHO means: accurate neutrality, more easy to write than to achieve.

If you have some coroners available, K-Horns, by Klipsch. Properly set up you can get to down to 20 hz. Been there, done that.

Buc, WTH does a local gov't official have to do with K'horns? :)
