How about one of the anti vibration clips? Make a bracket to hold the speaker and attach it to the clip after it is screwed to one of the 2x2's. You'd be able to rotate it on the single screw and relocate it leaving only a small screw hole that would be easily filled. The screw with a washer would clamp the rubber grommet to the wood, isolating the speaker.

PS Season's greetings and happy New Years!

I may end up moving them 50 times, that would leave 200 holes... so I'm definitely looking for a clamp of sorts that can be move without leaving marks worse than paint scratch.

Have found something, need to find out if it can take the speaker weight (which shouldn't be a lot, it's a tiny one).

--

Hooked up both the front highs and the front wides and played some stereo music on them two and two to find out if my placements agreed with the speakers and I must say it worked beyond expectation. Sonically I did notice that they are quite a bit brighter than my main brand, so they could really need some serious EQing later on for a closer timbre match.

Merry Christmas and a Happy New Year in return!

4 ceiling speakers now temporarily mounted in the ceiling. Time to don the mad scientist cap and try out the format I dreamed up...

First a couple of old pics that never made it online at the time... this is from adding a couple of polyether mattresses to the dampening walls

Here's how it looks like


And this is how three of them looks like put up (and you get a new pic of the speakers too):


The stand that the center SHOULD be on if it were not fot the non-AT screen is on the right. The 'black ghost' is and Wijk Wizard Jr. Signature spreaker on it's original stand. No use for them currently.

Here's what I made up to temporarily hold the ceiling speakers:

If you were in Canada, you'd be using Duct tape instead of the blue straps!

I have considered it, but I felt it might lead to problems later when I have to repaint them - if there's any tape residue.

And that would take just the glue leftovers and not the paint below?

Yes, unless the paint is oil or the new hybrid and is fresh. Methyl Hydrate alcohol will actually soften oil paint (I use it for stripping antique hardware). Acetone would take off the residue, but you'd have to test it on the paint to see if it attacks it.

When in doubt, put a little on a cloth and rub somewhere inconspicuous. If colour comes off, it is dissolving the surface material, paint or what ever.

Not sure, but I think it's car paint.

In any case, I've moved them five times so far and it seems to work quite well this way.

Atmos has made it easy for themselves to have separate speakers - using four as a single VoG requires a lot of measuring. Max distance difference between any two must not exceed five feet(=milliseconds). When I tried the back two narrower, the front one on the diagonal (relative to back seat) was starting to get noticed and the difference then was 1.5 feet too long. So the back pair went back out and I also moved the front pair slightly backwards.

The Nightlord Extended Surround does not seem to break the overhead effect in Master and Commander and it do seem to fill out the soundspace - it's not the "ring of sound" when listening with eyes closed, it's more indeterminate.

I do need more/cleaner power to them, but I have channels left to utilize, just need to draw cables properly.

Have drawn longer cables to the rack now and am using the same Marantz 5-channel amp as for the rest of the surrounds. Pushing it a bit with a three ohm load, but it's very little sound asked of it to amplify. (If you have the possibilty, try listening to just the surrounds sometime, it's amazing how little sound they actually output...)

Have more work todo with signal cables and with a bit of luck some buzz might go away, but I have it reduced to just noticable standing up near the ceiling speakers.

Currently I'm just adding the common signal to the VoGs without removing it from the sides. I will try that too, but it might be too aggressive steering.
