I had my custom moderate size listening room designed to accommodate 6-12" woofers at high efficiency, 98db. Now I get 25 Hz down just a few db. Bass is not an issue. This is very superior to my prior room which was 25' X 20' X 11.5' where I only got 35 Hz and bass response sounded heavy and uneven. The quality of the sound is 100% more satisfying/dense/rich with the same equipment. I also use acoustic tweaks including a double pair of Hallographs and a slew of SR HFTs, some ECTs and GCTs. I don't claim to get the best sound I ever heard but sound that one has difficulty leaving the room or running to the room to get to the music. I've heard 100s of systems over the years. The $1 million VAC/Von Schweikert system sounded the most life like. That system was large in a very large room but provided whatever the character of the recording, close or distant with all the ambiance that was recorded (or reverbed). It also provides a bubble of sound that emanates so that it spreads throughout the room, unlike most box speakers and many stats I've had. Advanced box speaker technology can rival any other tech design. It can be costly. I can make do for now with a great room and very good speakers that bring me to the music as it was recorded, near, far, in-between. Music can literally pop out at me, at all frequencies, just like live music at all levels of dynamics. Only orchestral music sounds compressed to some extent, often the recordings' fault as well.
