Elevate Subwoofer?

Well, you either deal with that or this:

Felt pads, not surprised then. Pretty sure the coefficient of friction on felt is similar to ice.

Silicone is rather slippery isn't it? I suppose there is no harm in trying, and it's quite cheap. I'll look for something suitable.

I just ignore the problem because the subwoofer only "walks" when someone comes over and plays loud music. With my normal listening it's not a problem. I guess the poltergeists don't mind my music and only register their displeasure at my guests

Silicone is similar to synthetic rubber. The advantage of silicone is it won't rub off on your wood floor like rubber might

I've had "silicone" rubber leave marks on surfaces. May have been misdescribed/marketed, tho. Generally I've used harder cabinet feet without issue.

That's what the sub is supposed to do to the room, not to itself!

A friend of mine loves to play with his stereo, and one of the trials concerned his subs' placement. His recreation room is quite long and dedicated to the stereo, so he can place things wherever he wishes- lucky him. After moving the subs around and listening, no measurements at hand, his subs ended on stands, after being on chairs, about 1/4 of the room height and about 1/4 of the room length- voilà!- nearly perfectly even bass top to bottom. He had placed the subs at the points where the standing waves of those dimensions were effectively cancelled, or so it seems.

Thanks for all the advice.
Suggestion for moving sub guy:
Call Ghost Busters and avoid tracks containing walking bass.

Could be worse. Imagine rolling basslines. Your sub be like

negatives in placing the speaker that high off the floor?

All four of my subwoofers are positioned at half the height of the room. This arrangement undoubtedly has certain advantages with a certain configuration.

Yeah and it compresses over time and will leave a mark.

Elevating my Sunfire True Sub Signature at around three foot height yields excellent results in overall bass response and LFE performance in my 2.1 system. I have to turn down the gain when the sub is elevated as opposed to being placed on the floor. In both positions I do have the sub placed on an isolation platform, which has also made significant performance improvements! I also have a pair of Rel Subs in my 7.2 HT system that are elevated but by only about 6 inches. Still they definitely sound better than when not elevated.

I had a similar experience a few weeks ago.

I have a total of four BIC America/Acoustech PL300 II subs (highly recommended; see the Audioholics test and review.) Two are stacked in the front left corner behind the main speakers and two more are stacked on the right.

I recently moved them from the floor about 18" (47cm) in front of the front wall and onto some concrete pavers stacked in an inverted L shape so they can sit on top of some built-in window bench seats, to take up less floor space. They now sit 23" (58cm) above the floor. I have heard and measured no difference in performance. They still make a solid 16Hz as per specifications.

Further on this, are you familiar with Welti's and Devalier's research on sub(s) placement in a square room? Their conclusions are that 2 subs at mid points on opposite walls give almost as good, meaning even, bass response as 4 at mid points. As I recall, Floyd Toole recommends instead putting 4 in the corner and using sound field management to even out the worst standing waves, for the added output of the subs from corner placement.
