Subwoofer Footing - Connect or Isolate?

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.

Yes, so much better to avoid isolation.  I mean, those subwoofers just don't seem as cool if they're not making my walls rattle, or vibrating things off shelves, or making the woofers pump on my speakers when I'm spinning vinyl on the turntable.

The last thing you want to do is put a subwoofer on springs. At some low frequency it will start shaking. Vibration/shaking in any speaker equals distortion. Just put your hand on the sub while playing an organ piece or better yet run a sine wave sweep and you can find all the resonance points. Keeping a subwoofer from shaking is not easy. Certainly, mass helps as does containment. In the home environment spiking it to a concrete floor would be best followed by spiking it to a wooden floor. The wooden floor's resonance point will hopefully and usually be above the subwoofer's range. Even so the floor is going to resonate regardless from airborne excitation. New designs Like Magico's big subs are using a method of force cancelation. They put drivers in opposite ends of the enclosure running in phase with each other thus their Newtonian forces cancel. This effectively stops the enclosure from shaking but does not stop cabinet resonances, another issue all together. Magico does it by building a battleship enclosure.
