I used an inexpensive cork/rubber disk to little effect. Then I tried the IsoAcoustics Gaia II and was amazed at the difference. I’ve got hardwood floors upstairs and vinyl tile/carpet over cement on the first floor. In both cases the Gaia II footers made a noticeable and pleasant improvement in the sound and soundstage depth. My speakers are XStatic EC/X, 40lbs each, used 4 footers each. YMMV.
Under my tower speakers -- Isoacoustics Gaia, other options?
I have Ascend towers (45lbs each) on a concrete floor covered in thin wall to wall with an area rug on top of that. I am looking into different footers for my speakers and am curious what people with towers on concrete have tried and liked.
To my mind, something as expensive as Townshend platforms do not seem worth it, as they'd cost about a third of the price of the speakers themselves.
If you've tried Gaia III isolators or other kinds of feet for your speakers, especially on concrete floors, I'm curious to hear your observations. Thanks.
