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.

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.
Price range?
My Zu Definition 4's will pump out about as much bass you'll ever need and the high efficiency should fill that room just fine.

Buconero117,
K horns down to 20 Hz? I had those speakers for over 20 years and always struggled to get any good deep bass out of them. Ended up with a Velodyne sub which did the trick. Oh well, maybe I had them set up wrong.
