IsoAcoustics Gaia II Carpet Disks (Set of 4)

Used these with Gaia Isolators on my 65 pound speakers. More slam and tightness in the bass without changing the sweet mids and highs.

I know it’s hard to see them in the photo but they’re doing the work as advertised. Helping decouple an equipment rack paired with a the Gaia’s.10/10 recommend.

Placed them under my speakers and things got louder and more focused. Well worth the price.

These added a minimum or subtile improvement to my Subwoofers (2). But they linked them directly to my floor instead of just sitting on top of the carpet. At loud playing deep bass the subwoofer play music and not vibration.

I chose IsoA Puck 76 for my floorstanders, which suggested the large carpet-spike cups that unfortunately sell for a whopping $180/4! I chose instead to glue the GAIA 1 onto the bottoms of the 76ers for a fine, and more invisible, look. That these have a spike tripod configuration makes them self-leveling, but where four are used in the corners I'm not sure that's critical. Applying glue to their upper outer edges and centering on an upturned IsoA sorbo pad is a bit tedious...but affordable (($40ea 76er +$16 cup) x 8=$450) rather than more jeweled GAIA 1 (($80 +$16) x8= $770), especially if using the oversized cups ((80+$45)x8=a cool $1k!). So I recommend sticking with the half-price IsoAc pro Pucks and gluing on the smaller GAIA cups if necessary.

Sound quality

Spikes are long enough to penetrate my medium thick carpet.

I ordered to sets of these, they were pricy, but I hoped they would work out for me. It seems the spikes could be longer to allow them to fully penetrate the carpet and padding to rest on a solid surface. They help some, but not as well as I hoped. We had about 8 Earth quakes here in the last couple of days. The speaker boxes did stay put so they might be good enough. I haven't had a chance to evaluate sound quality since all the drivers are out being restored.
