Axiom Home Page Forums General Discussion Advice from Axiom Owners Full Metal Bracket with M22/VP150?

The fact that you are even considering first reflection points and are conscious of treating the back wall (presumably for echo/bass improvements) is a big leap in the right firection. You will be pleased.

From my experience, if you arent going to measure the room, what you are looking at doing would be the extent of what you should do. FRP and echoe treatments are "do no harm" measures. Corner bass traps are also universally a good idea.

Beyond that you really need to start looking at frequency vs decay time plots. Otherwise you can suck too much energy out of the room in a narrow band of sound. It gets pretty geeky down that road.

Well, it is certainly good to hear that I'm heading down the correct path. Thanks! I know a lot of the basics but never got down into "the math of it."

It will be an interesting room, b/c most times there will be 3 people watching a movie, but when we have company, there could be 10+ people in there. Bodies soak up acoustical energy and change the way sound moves through a room. I don't have a lot of money to throw at "acoustics" hence my home made acoustic panels and heavy curtains at the back of the room.

My mount failed. VP150 fell, tore my screen, a screen material I could not get anymore, and I ended up with an inferior screen as a replacement, and I am still using the vp150. Axiom claims the mount was over tightened, I beg to differ. I blamed the very cheap screw mount which cracked and failed. Thankfully no dogs, kids, or ME got injured as it fell late at night.

I was not a happy camper, and Axiom did not really give me the support I had hoped. Regardless, I have remained an Axiom loyal customer, but still....their mount failed. Cost me a new screen.

It has since been remounted, with a thicker screw mod I did, but now is below the screen.

The basics laws of physics would make me want to build a shelf. Of course, I've always had a tendency to over-build everything.

Yikes Newf! Glad all was ok people wise.

Wow, I read that whole thread, Newf and sorry to see what you went through. Luckily, no one got hurt, but your screen...that stinks!

I can see the logic of having the extra holes in the FMB to put screws through, and should I mount my VP150 with the FMB I'll probably do just that.

But I can also see the logic of re-engineering that piece of the mount to incorporate two bolt holes instead of one. Yes; that would mean redoing the CNC files for the whole axiom line to drill for two threaded nut inserts vs. one. But really, how much work is that? A few minutes? And it would add exactly 10 cents to the build cost of each speaker for the extra threaded insert.

My personal opinion is that the single mount point isn't the best-engineered of ideas for the VP150 and it's debatable for the M22s as well, though I will probably do it for the M22s, pending my seat-of-the-pants testing/impressions.

Holy crap, that is a lot of weight (22lbs) to hang off a cheesy little insert , which from your pictures looks like it should be inserted the other way so it bites into the wood. Anyone mounting a VP150 should pull out the front drivers and put a plate on the inside and use a nut and bolt. I am surprised Axiom didn't stand behind that since they claim that mount will work with a VP-150.

Aside from the aforementioned opinions on the mount, i fail to see why ANY mount wouldn't have at least 2 points of contact for mounting. This greatly decreases the risk of a failure of a single point causing so much damage.

A decent non-shearing screw still only costs a few cents each.
