Speakers with deep/powerful bass

GoldenEar Triton One.R's. 

I was with my friend George Bischoff who was the main designer of Scaena speakers at Harry Pearson's years ago. The Scaena were line sources with planar tweeters and dynamic mids. The woofers were powered modular 18" woofers with equalization(actually they rolled off from 180 Hz but were rolled in about 65Hz and equalized flat to about 16 Hz and yes it took hundreds of watts). I believe Harry's set had 3 sets of bass modules.

Anyway we were playing a cut from a CD with music from the sound track of a movie called Lost World. The cut we used according to Harry had a real volcano in the trach that went down to at least 16 Hz. Harry liked loud. And as the cut played I looked at Harry's and my friend's eyes and they were like saucers. I could tell they were waiting for flying woofers. But all we got was tons of very tight loud bass.

I got a copy of the CD and have tried it on multiple systems that claimed they went DEEP. But nothing, so far, has come close.

I had Salk Songtowers that, all of a sudden, had deep, powerful bass. Had them for years before I put them in a new position. I thought the reviews of this speaker’s bass response were mostly hyperbole until I placed them in a decent room, in a decent spot with nothing between them or around them but air.

It’s really the room. I’m guessing most of us have no idea what our speakers are truly capable of. I don’t even think I found a perfect position but simply came closer than any time before.

So really, I had a room that produced amazing bass. I've since moved, sold those speakers and have invested triple my investment. Although I like the sound of my new system...it really falls short of that room...

I have a pair of AR303s that are driven by a Parasound Halo A21. 12" woofer acoustic suspension "Bookshelf". They are set 4 feet above the floor. Enough bass to shake the room with the right song or movie. No subwoofer needed.

Just buy some Svs 4000 or ultra subs they will go lower and with more impact 

with their high current amplifiers built in and 13-16 inch drivers 

buying 2 will balance out the rooms Bass.
