Axiom Home Page Forums General Discussion Advice from Axiom Owners VP 150 holding me back...

If you walked up to one of your 80s and pushed it, would it start swinging, or are they attached in solid way that prevents that? If they do swing, you run the risk of losing some accuracy. Allow me to explain my theory.

Because every action has an equal and opposite reaction, when your driver cones move forward, your speaker cabinet will move backward, trying to keep the center of mass of the entire speaker in the same place. Likewise, when the driver cones move inward, the speaker cabinet will move forward. Because the speaker cabinet has much more mass than the drivers, you can't really see this happening. The effect would be a subtle muffling of soundwaves.

It's always a good idea to have the speakers anchored as rigidly as possible.

I fully admit that the motion of the speaker cabinets themselves might be small enough that it's virtually non-existent, so this may be a complete non-issue.

I had reservations with the VP 150, that's why I ended up buying two M22's and running them both as a center. I love them.....

They are currently laying horizontal on an angled shelf that ponts them downward. I tried laying them with the tweeters together, and with the woofers together. I prefer the tweeters together. They blend extreemly well with the M80's too. Much better than the M3's did when I was using them as a center channel.

When I move all this to the dedicated room, I'll position the M22's vertically, but for now, I have no complaints whatsoever. They friggin rock.

At long last, yes.. If you can believe this, they have been flying for years, and I put off taking photos as I was going to wait until I 'FINISHED' the room !!?? haha.. Like that will ever happen ?? hahaha..
Now, if I can just figure out how to post the shots..

In the past I would run a chain or heavy wire from the back side of the speaker box to the wall behind it.. That gave me 3 points of contact.. It was more for aiming the speaker at the sweet spot, and as I have never finalized the seating in my theater room (funding issues !) there has not been a permanent spot to aim at..
They weigh 57 lbs each, so with the laws of inertia in effect, not a lot of movement going on..
They play loud and very very clean.. Yes, you do have to drill pilot holes in the tops of them.. Many of my friends used to freak about that.. I've been doing this to my speakers since 1972, and never had a problem with a speaker falling, or coming apart at the seams, etc..
Again, I have photos, and will "TRY" to post them.. Soon..

What inserts do you use? MDF isn't known for great fastener holding strength. - be careful.

Just have to say that I had some conerns about the 150 before purchasing because of certian reviews / threads and I can not be happier with the speaker...

To answer off axis concerns... they simply do not exist for me.. the tmmmt set up works.

My question also is this: Are other speakers being used as centers as sheilded as the 150? Probably but I wonder if you see any effect of lack of shielding on the 22s etc...

From my testing, they are not as shielded as the VP series. The M22s were pretty much unusable next to my CRT. Well, the M22s were fine, but the CRT was another matter. It's just fine with the VP.

That makes sence due to design... thanks for the confirmation.
