Vicoustic DC-2 diffusers

You must be doing something wrong Joz😁. I have 10 x DC2 for 18 months and only one adhesive has failed.

Shane, I think Joz's bad experience was with the heavier Wavepanels. The problem is not just the weight IMO,  the 3M strips just work better with the more rigid DC2 panels.

Mine were the heavier panels as shown here in the pics. Bloody annoying having the edges of the panels crushed when the fall.

The sticky tabs let go of the walls 😤

I have now moved onto a more permanent fixing solution.

Same here, the sticky tabs always let go eventually.

They will fall off... Especially in summer.
Second time round I stapled the adhesive labels into the plaster of the walls and ceilings. Haven't yet found an effective way to properly secure the labels to the Dc2 panels hanging above my seating position-had one just fall from my roof on Friday.
With wavewood panels I glued mdf panels onto the spongy backing then stapled the adhesive into that...no problem with those

Having listed all my excuses above - I decided to bite the bullet and try short wall placement.

Bottom line: I like it!

As predicted its eaten up some available space and I now longer have room for my recliner and headphone nook - not sure the less open look has been welcomed by my other half either.

Now have to experiment with re-placement of the diffuser panels and other treatment. But even without adjusting any of the diffusers, and just placing a DIY panel at the first sidewall reflection points, it sounds excellent.

Just wondering after living with the rearrangement along short wall now for a little while are you still preferring the performance with this orientation?

Is there anything about the sound that is not optimised having it configured this way and have you adjusted any of your acoustic control materials that were still in situ from the previous arrangement?

 

I have had my own system firing across both long wall (5.8m) and how it is currently set up with speakers across the short wall (4.3m) for extended periods.  I am about to try it again with speakers across the long wall, hence my questions about how you have found the change.  My only issue I had was sitting so much closer to the back wall was problematic.

 

Cheers

Chris, I'm still preferring the short wall placement for SQ and getting used to the new arrangement. I see your dimensions are very close to mine (6x4.3x2.7m) and that's a nicely shaped room, so you can get good results with both positions.

I think short wall placement offers the most potential and, in the case of the ATC's I'm using, is probably more along the lines of what the designer intended.

As always you have to work around domestic considerations. In terms of space usage the long wall placement was better (for me) but I'm going with the short wall setup.

 

The biggest improvements with short wall placement (with speakers and seating position almost 2m off the front and back wall respectively) is the greater image stability and depth perspective. There is much better discrimination of acoustics/ambient sound in recordings and the relative positioning of sounds. 

This is not to say the long wall placement was bad in these respects, but in hindsight the comb effects created by proximity to the rear wall was messing with the sound - despite treatment to mitigate the impact. Nonetheless I was getting very satisfactory sound on the long wall.

 

The speakers are placed very close to the classic equilateral triangle with the centre of the front baffles about 2.6m apart. 

 

After some experimentation I've ended up with the DC2 diffusers distributed around the room. Treatment is symmetrically placed left to right.

Side walls now have 120x60cm Wavepanels added - originally ordered to try on the long wall setup, but I'd changed before arrival. The vertical panels are at the first reflection point (I found these to sound better than my DIY panels in this position)

I said I wasn't going to bother with the back wall, but I found that some extra diffusion improved the sound.

Yes interesting our rooms are so similar in size.

Cheers for letting me know how you have settled optimising the distribution of acoustic treatments in your room.

Even though my gut feeling is I will come to the same conclusion you did, I still think I will try my Voxativ speakers along the long wall just to be sure which orientation gives me the best sound.

Cheers

Long wall has definitely helped with spaciousness. Using artnovion brand of sound treatment for absorption, diffusion, and bass trap.

Where did you get your Artnovion gear from?

I heard them in Antwerp last year and was very impressed.

You are obviously a very 'neat' guy! 

- also some artistic and aesthetic qualities.

Do you have a little OCD too ? 🤣

Great discussion! I had some doubt that the adhesive strips would work with the foam viscoustics so ended up putting a couple of brackets on the wall so the diffusers just rest on top of flat lengths of wood (raised for a bit of extra height).

More permanent than adhesive but I will check in on this thread again down the track to see the long term success of adhesive strips as they sound much simpler!

Nice! What are the diffusers with the wooden frame?

They are Furatech diffusers, quite expensive with their silk covers, etc. but I was lucky to pick them up in the Classifieds on SNA :)

Ah thank you. Nice score then, they sure do look the part!

The best thing is they actually work! The local seller kindly let me try them for a week and it was a definite improvement...better depth and soundstage, not night and day but enough that I had to keep them :lol:
