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.

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?
Whether you prefer spikes or not it is indisputable that their use increases the amount of resonance measured in the baffle.

As usual it boils down to where you want to put those unavoidable resonances. Nowadays we are seeing a greater awareness of these issues in the design of loudspeakers and microphones.

Suspended mic's in my experience sound pretty, pretty good. Certainly on speech.
It depends on the speakers, I liked them on Dynaudio confidence, on my ESL 63's a big no go, just made things brighter, same for my OB speakers, yes they sound cleaner, but you can lose the meat and dynamics in the midrange, while when spiking the highs and lows sick out better, but that is not always right. In this hobby they are no always a set rule for many things, you learn as you go is to stay open-minded and try things and see how it works out in your system. Live music does not sound like many spiked speaker systems I hear, take the blinders off, and find out what is best for your speakers.
