Subwoofer Footing - Connect or Isolate?

Put it on springs. Much better. Nobsound springs if you can only afford $30, or if you want the best then Townshend Pods or Bars. Pods are virtually as good but cost less and I think look better, as in you hardly see them.

The curling stone is maximizing vibration feeding into the floor, walls, and ceiling. Vibrations travel through all these setting the whole room ringing. A lot of what you think is bass response or room acoustics is really the sub exciting the walls turning them into speakers muddying the bass and everything else. Travels into all your components distorting them as well.

Springs eliminate all that, allowing the speaker to radiate into the room sound waves not sound waves plus mechanical vibrations. The improvement in clarity is not subtle, not if you go Townshend anyway. But even Nobsound will be a big improvement from what you are doing now.

Dont elevate the sub, or De couple it from the floor as this will tend to make things sound dead, you will kill and rob the life out of the sub, this is a key quality that REL subs have. REL's not only produce bass they have a musical sound that works and enhances the main speakers, this will be lost if you isolate the sub from the floor, use bass traps or other resonance absorbing material in SPECIFIC areas to combat this.

You can't connect but you can Isolate it.. Always! Vibration in, Vibration out. Isolate from both, THEN remove as much as you can from the cabinets.. Speed the decay rates on everything.. No there's not 10,000 words.. My hands hurt.. :-)

The reason Matt says "tend" is because he doesn't know. If he did know then instead of pasting ad copy he would say springs and decoupling "are" better. Because he would know. From experience. https://systems.audiogon.com/systems/8367 Five subs. They have been on Cones, springs, and Pods. Springs are better than Cones. Pods are much better than springs. "A musical sound that works and enhances the main speakers, this will be lost if you isolate the sub" oh really? Read the listener comments. Please.

Some folks like BASS exciters hooked to there seat. Maybe mattmiller is one of those. What ya think? REALLY likes to feel it.

TT guys tend to pay just a little more attention to vibration mattmiller "I Like the Feelin'", don't work to well..  Different approach.

Baffle widths, flat surfaces sharp corners, all take away from "Sound is Round" "Smooth" "Clear" "Fast". 

EVERYTHING with uncontrolled vibration and every surface that collects it add to the issue. It's pretty weird when you get rid of it for the first time..
AND get to hear the difference.

It's also nice to have cabinets that sound like a fresh telephone pole when you knock on it. Curb and gutter type of quiet.
