Removing spikes... Now my speakers sing


Have you tried to replace the spikes under your speakers, and replace them by footers ?  I find a better unity in the music from my speakers, and beefy sound, and more natural music.

@labtec   I stand corrected!  I forgot that you were not using the spikes. I actually have a Bright Star sandbox on top of my Target amp stand with my amplifier on top of the Bright Star.

Your point about chairs, listeners heights varying is, of course, quite correct.  As a Vandersteen owner I am perhaps over sensitive to the height issue as Vandy's have to be pitched just right according to listener's ear height for the treble and imaging to lock in.
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?
