Do we really need anything more than 8" woofer and 1" tweeter for medium size room?

I run dual 15" woofers at home. My room is 17' x 22'; which is about an average size. They sound great in there. I don't have neighbors I can disturb so I play as loud as I want.

At work, we use a little monitor with dual 6" high excursion woofers, that are custom built to keep up speed-wise with a very fast (and revealing) tweeter. They are made by High Emotion Audio, the heir of the old Pipedream operation of years ago.

The owner of the company told me they are 'honest to 36 cycles' and that sounds correct. I've often been amazed at how well they can play bass. Obviously they are not as efficient as my speakers at home but they do a very passable job (93db, 16 ohms). If you have a smaller room they would work fine. A lot has to do with how much excursion you are forcing the speaker to make in order to play the volume you want.

Don't remember his name, there is a French designer who makes great drivers used in some esoteric speakers. That driver goes down to about 40hz and up as far as you can see or hear. I think, it's 10" driver but not sure. The quality of that driver really impressed many people. I even watched an interview with him. Basically, he is a one man operation. Old world craftsmanship.

I'm pretty sure you are referring to PHY...

We had a set of those 10" units in a box, made by an associate of PHY. The boxes were rather large, and built like an acoustic guitar body- designed to resonate as a means of extending the bass of the 10" driver. Overall, the little HEAs we have with the 6" woofers play deeper and more accurate bass.
