Corner treatment -- PZCs a sure thing?

Jay here's a link which explains the tuning better than I can
http://www.soundstage.com/revequip/db05.htm
yes also using four mini controllers 1 on each walls midpoint top seam. the corner four controllers really help considerably they virtually eliminate any slap echo your room has results are notes leading edges and decays are much more clearly rendered you hear more of your speakers and less room sound. Adding the mini controllers is similar effects. The room walls just are not there any longer.

Thanks, Mejames, I hadn't come across that article.

Hi Jayboard!
I only noticed your question today.
If you're in doubt about the PZCs as corner treatment (who's gonna blame you for that?) you could try to build your own, first.

Here are some pictures as to give you an idea as how to imitate them:

Now, the wooden face plate is something very important!
Standard PZCs have cherry face plates, but you can choose any wood of your likings. Check out some guitar building sites for inspiration.
Use very thin layers of VARATHANE to treat the wood;
making it hard on the outside but soft on the inside of the wood panel!
Then proceed like this:

Make sure there are washers between the face plate and the frame: http://www.htforum.nl/yabbse/index.php?action=dlattach;topic=47451.0;attach=32147;image
Tuning the face plate can be accomplished by attaching a tuning bolt to the front bracket and the face plate: http://www.htforum.nl/yabbse/index.php?action=dlattach;topic=47451.0;attach=32148;image

Good luck!

Kind regards,
Roy.

What are your thoughts on combining PZC's with other room treatments? I have a pair of ASC Shadowcasters(tunable version and no longer available) that control first reflections and can be made to absorb and reflect at the same time.

The Eighth Nerve Adapt product is considerably better than the PZC. PZC's might work for you if you have a very large room, but I found them to be incredibly absorbent and they shut the sound down in an average sized room.
