Under my tower speakers -- Isoacoustics Gaia, other options?

I tried concrete slabs and Gaia's ll under my Audiovector R6 arrete but  still had bass reverb you can do a Townshend search on the Audiogon  forum and read up on other members success with Townshend 

@hilde45     Yes, the Gaia work quite well doing all they need do.  For lots more money it's the Townshend.  If on carpet/rug the carpet spikes used in conjunction improved the sound as much as the footers.  Really a weird affect to me.

@hilde45  - Are the bases already drilled/tapped for spikes/feet? If so, I would recommend a set out outriggers from parts-express. It will provide a bit wider stance, increasing stability, and provides a good platform for the spikes. The spikes will pierce the carpet and go down to the concrete, providing a nice stable base for your tower speakers. You can still use them if your speakers are not tapped, but you'll need to drill holes for the anchors. 

I use an anti-matter reactor system that keeps my speakers about 2" 

above the floor surface at all times. I have found this to be 

the best way to eliminate all unwanted vibration. Available through

our friends at area 51.

Of all the tweaks/upgrades I’ve employed in my systems, the Townshend podiums made the largest improvement, by a wide margin. They are transformative. Highly recommended 👍🏼
