Best treatment for speaker feet????

I would also consider contacting Herbie's Audio. They're not extremely expensive and they have a nice wide variety of solutions. If something doesn't work for you, they would take it back in trade for something else to try. Most importantly, if you tell them your situation, they will provide answers backed by a warranty. I'm about to place and order for Big Fat Dots to put my monitor stands on.

Nice to see you on Agon Jaxwired.

I totally disagree with Nsgarch's comment that decoupling is always inappropriate. With carpeting, coupling makes sense because the carpet pad drowns out the resonance. On a wood floor with floor standers, decoupling is the only way I've ever had success. I actually went two years with my speakers on Aurelex Grammas which are made for guitar amps that sit on raised stages. I would spike your speakers and be done with it. I use a caliper to get three of the 4 spikes set even with each other and tight and the fourth one close to the other three(always leave the front right side as the loose one). Once in place, you set the fourth spike.

Jaxwired. I didn't see you response to me from the other day. Those outriggers look like a great idea for your situation. I'm glad you like Herbie's because I have some Tenderfeet coming for my CDP and Big Fat Dots to put between my speakers and stands.
