Removing spikes... Now my speakers sing

Stillpoint 5's under my Wilson Sophia 3's couple the speakers to the wooden floor, making the whole listening space resonate. 

Three points determine a plane. Four points do not necessarily determine a plane. That’s plain old plane geometry. Thus, oft times three cones will be less wobbly and sound better than four. For tall heavy speakers four cones can be a little dangerous inasmuch as if someone accidentally bumps into them they can fall over. Which is why large footprint boards should be used under the speaker with the cones under the board. Much more stable.

General rule to couple (spike) or de-couple (not spike) speakers to the floor, comes down to what floor you have.

1: Cement slab floor on mother earth (not cement sheet) = spike (couple)

2: Suspended floor wood, sheet, (includes cement sheet) = no spike (decouple)

If you spike a speaker into a suspended floor as in 2, you transfer the bass of the speaker into that floor, making it a sound board for the bass and ruining it.

I've experienced significant gains in transparency and cleanness of sound by decoupling my speakers from my carpeted basement room.  After hearing the improvements in the main speakers, I decoupled the subs.  Have great tight deep bass and greater transparency still as the ruckus inherent in subs. is not vibrating my rack mounted gear.  YMMV.
