Axiom Home Page Forums General Discussion Home Theater Speaking of mounting center channels with FMB...

Wall-mounted M80, you say? Back before MarkSJohnson became the quick-draw master of the forum, I put together this diagram showing how a horizontally wall-mounted M80 is not a good idea, at least using FMBs. The green crosshairs is my guesstimate at where the speaker's center of gravity would be. The area of the wall where the FMB is mounted would be getting a TON of torque.

Take some pictures... I've always been a fan of a horizontal center channel, which is why I like the VP150, but using an m80? I just can't see how that'd look, so take a picture or 100 please!

Hi nickbuol, I've had my VP150 mounted to the FMB with the single supplied bolt for months with no issue. I did however use longer bolts to the stud like the other poster.

The one thing I noticed though is that no matter how tight I put the single bolt the VP150 still can be moved fairly easily. It has never moved itself, but when I went to adjust the angle it ended up sliding a little to one side making it unlevel.

Currently my center is not center and I've tried to live with it but I cannot take it any longer. How thick was the piece of cedar used between the studs Daphoid?

Just a suggestion, I had the same problem with the 150 rotating some what easily with the one machined center bolt. I also had this problem to a lesser extent with my vertically mounted m-22s rears. I used an old bicycle inner tube, cut it with a single edged razor blade, traced the round FMB base that attaches to the back of the speaker while cutting the round rubber. No slips, no rotating straight stays straight. It also protects the speaker cabinet providing a cushion, less rattle - shake factor. It is thin enough that it has no asthetic changes.

That is an outstanding, low cost, simple, and elegant solution! I've got my m22s mounted horizontally with FMBs, and I think I will try this.

Thanks for sharing this one!

Great idea joninflorida, I may have to try that. Did you have any issues with the tube sticking to the finish or anything?

NO, not yet, it's been about 5 months. I have taken the 22s off twice, as we painted the wall. no sticking or any other cabinet concerns. I had a concern that without some type of barrier, if I over torqued the mounting screw, it may put an indentation in the raer cabinet/laminate. It worls graet in my house
