Tweak: raising the subwoofer off the floor...

Maxgain, to couple or decouple that is the question. Before you do anything, think about the idea of coupling that sub to the floor. You really cannot, fully decouple anything, but you can, surely, couple and send all those evil resonances to ground zero. Try the Sistrum Sub Support system. I use it for my sub. Quite a unique piece of engineering. Go on Starsound Technologies website and read their literature. I, also, wrote a review about their Mini Monitor speaker support system. It'll explain a little of what I'm talking about, but their website does it more comprehensively. They have a full money back guarentee. You won't have to use (the guarentee) it. Vibropods are an anethma to my ears. Once you couple there's no going back. You won't want to. Just think of this: all the work to decouple or isolate a component. How ever you do it, how to you keep away those airborne resonances? You don't. And then once those airborne resonances make their way into your amp, cd player,etc. the very isolating, or decoupling devices you're using, keep those deleterious, microphonous evil devils in your stuff. Check out their website. You will be reborn. Happy Christmas...warren

Maxgain, I saw the ASCsub stand and it looks interesting, but I am not sure as to how it traps bass. Have you done any research on this?

There is no reason to put woofers near the floor, just comprimises[sub to small needs floor boundery reinforcement ,most speaker builders place woofers near the floor because its the only place left also its traditional, people expect the woofers to be near the floor ]ask any dealer .people are scared by things that are diferant ,has to be a wood covered monkey coffin to sell ,boring!!!.try lifting it, if your sub is well designed and fits your room well it should sound much cleaner and better defined ,less standing waves .enjoy .

Matchstickman, Bass builds up in corners as standing waves. The sub stand is just like a short tube trap in a different shape and designed to sit under the woofer. The Tube Traps reduce some of the mud, boom, and colorations that happen by breaking up standing waves by a combination of absorbtion and diffusion. Read their blurb on the traps and it will explain it more to you.

Warrenh, You don't understand because you have not tried it, you just buy into their pitch and are their most vocal salesman, that's fine. I do what works for me in this area and you do what works for you.

This is simply a matter of reducing the floor boundary reinforcement of the bass frequencies. Getting it off the floor reduces the reinforcement of these frequencies by 3db and tends to make it less boomy sounding. It also may have the effect of having the speaker more in-line with the ear at the seated position.

Note: Use an open type of stand if you are going to do this. Using a flat front closed stand will not have the effect, as it will help to re-couple the floor boundary to the sub, and thus add back in the boundary reinforcement.
