Speakers with deep/powerful bass

JBL 4350 and Everest DD67000.  We have a pair of each in our living room, on adjacent walls.  This thread has given me a few new tracks to check out.  

For deep full, impactful bass, as well as overall good sound with a large open stage, I'd have to give a vote to the old PSB Strats Goldi. 

@Sandthemall is right--it’s the room. At least part of it is the room.

My biggest system was Vandersteen 4s driven by tube amps >80 Hz and by a heavily modded Adcom GFA-555 amp <80 Hz. Prior to the mods the Adcom was a decent but unexceptional bass amp; after the mods it was a ridiculously good bass amp. The Vandy’s had a pair of 12" woofers mounted facing in the same direction & coupled by a steel bar. The enclosure was vented. That was the best bass I ever heard--tuneful, deep, taut, airy, all the stuff I now believe ported subs can’t do (Vandersteen was/is a genius speaker designer).

Our house was built in 1825, all wood. There were something like 9 windows facing the living room where the speakers were; also many shelves with knicknacks on them. All those windows and knicknacks vibrated audibly when deep bass notes were played. On deep notes that sustained, like low organ notes, the effect was downright alarming. You’d feel a weird fluttering in your abdomen as your diaphragm vibrated along with everything else.

I love bass (IRL music and in audio) and that was an amazing experience.

JBL 4350 will casually handle anything you feed them. I have a pair of them in our large living room, along with a pair of JBL Everest DD67000 on the adjacent wall. Playing a Simon Preston recording of Bach organ concerti, cranked up they shake plaster off of the ceiling.  Actually, either pair will, but the 4350s feel more dynamic. I wonder how they would sound if I ran them simultaneously.  Hmmm…
