I finally got around to installing rubber feet to the bottom of my M22's after a YEAR! and all I can say is WOW. My wife had commented on the lack of bass from them when I first set them up. I just dismissed it as a lack of boominess compared to my old Bose speakers. I guess I was wrong. The fireplace mantle I have them sitting on was sucking the life out of them. We just finshed watching a movie and I turned off the sub during the music on the final credits and asked my wife if she noticed anything different about the sound. She replied it sounded like it usually does. I then turned the sub back on and it added very little to the bass in the music (low volume). She couldn't believe they were the same speakers. We then tried some cd's in 2 channel sub off. She is now a true believer in the axiom sound. I always loved the detail and now I love the entire sound. This would be a lesson in placement and stands and what they can do to your speakers. I never would have guessed that having a wood speaker on a big wood base(4fthigh by 5ftwide triangle)would do so much harm to the sound.

Jake,
That is so true about changing the sound of speakers by putting feet on them. I once hung some floorstanders on the wall and and it sucked every bit of bass out of them. I also tried them with feet (points) on the floor (much better) and then on top of a 2'x2' slab of concrete and that is where they reside now. HUGE differences. Well, I guess that is what they mean by tweaking.

Makes me think I should put the carpet spikes on my M50's.

Interesting post.

Can some of our resident gurus add insight on this general subject?

Some do's & dont's relative to speaker interactions?

The only tweak such as this that I've ever tried was lifting my M60's off the floor a bit. Mid-bass clarity may have cleaned up a bit. Not that the mid-bass clarity is bad on the M60's to begin with! In fact the mid-bass clarity on the M60's is the reason I bought them. They're the first tower speakers I've ever owned, because mid-bass on towers usually is muddy as all heck.

Yeah, I fell onto this trick several years ago when I was complaining about a set of Polks that I had bought. The fellow at the shop that I bought them from went into the back room and came out with a couple of packages of little rubber feet to put on the bottoms. Imaging, bass and general tighness in the sound improved dramitcly (why can I not spell that word?) Now, every speaker in my system is mounted on some sort of little rubber feet, and I have packages of them in all sorts of styles and heights stuffed into the drawer with all of the rest of the crap that comes with AV gear...
And I also really like the idea of using concret slabs under the Towers. I just got my set of M60's, and after they are here for a while I am going to go out and find a couple that fit under the speakers and set them on those. Cannot help but think that getting them on something solid, instead of squishing into the carpet would go a long way. And I also like the idea of raising them up, even just a bit, as I listen to so much of my music and movies while standing in the kitchen at the back of the room.
I love all of the tweaking stuff. It is half of the fun!
