If any, I'd put the spikes according to your left drawing, as the drivers usually are bolted to the front baffle, thus locating the center of gravity next to the front.

Best regards!

D: in the garbage. Spikes are pointless, and can damage the flooring in higher end homes.

Perhaps you should enclose your speakers in pyramids?

Joking about expensive gimmicks aside, I'd like to comment more positively on speakers. I used to put heavy cinderblocks on my subs to help anchor them. Not able to do measurements at the time but maybe somebody could now.

Probably good idea to rigidify but you'd need three sharp spikes sticking into your floor and a cinderblock to do much good, as previous posters said. Any speaker power that ends up shaking the box has to be in weird ways and therefore has to be all distortion.

Not likely that 4 spikes would be co-planar or that a flat box would be either. So good to use some kind of firm but rubberiferous gasket sheeting to accommodate irregularities in seating the speaker on the floor.... assuming that's the right height.

What does make a lot of difference is moving speakers around - even just a foot - because that can cause big changes in performance. But you can't do that kind of improvement without REW to measure incremental changes.

+2 to Pallas and bifor , and as I think Ben is saying, securely anchoring / "coupling" with spikes through carpet into either wooden or concrete sub-floor or directly to the floor itself is not as easy as you might like hope.

It's been my experience that mass loading the bottom of the enclosure with either sand / birdshot pellets, or quartz slab glued with silicone, and more importantly finding the right location will yield more benefits than spikes. And yes, it's way too easy to damage very expensive carpet or wooden flooring with spikes.

But, if you really want to try them, I'd go with #1

nr1 with soundcare superspikes

Most stable, most weight is on the frontpanel with the drivers.
But with soundcare superspikes you can install four of them because they're easily adjusted by hand.
