I've had the Isoacoustic Gaia II for a couple of weeks, but inconclusive as to whether bass is tightened or attenuated. They restrict box movement to front-to-back, but couldn't that result in the bass cone not pushing against a solid plane? That is, the cabinet moves back when the cone moves forward, reducing the absolute throw and transient speed of the cone? The mids do seem a little clearer. I'm on a suspended wood floor, so would a rubbery foot be worth trying?
