I'm in dire need of four surrounds. Is the 2 pi suitable for on-wall installation? Will they perform well at about 5' to 6' above the floor?

I'm also interested in building a trio of 4 pi for LCR duty. Will need to modify my screen to AT first, and start saving my nickles and dimes.

I'd appreciate any suggestions, and a set of plans.

Thanks in advance

I'm running two π studio monitors for my surrounds. I think that's the perfect application for them. They don't really need a lot of bass extension, just to match spectral balance above the modal range. So they're perfect when used for surrounds with the larger (3, 4, 6 or 7) models as mains. And wall mounting is a good way to go. I personally have my surrounds on bookshelves, beside and behind the listening area.

I appreciate the feedback Wayne. Please send cabinet drawings when you get a chance. Don't need the 4 pi drawings yet, since I have looked at a bunch of build threads and have a pretty good handle on what's involved.

I do want to build the 2 pi's sometime this summer.

Thanks

I'm finally moving on this project. I ordered everything from PE last night and have Baltic Birch plywood in stock. I'll start making dust this weekend. I'll post progress pictures here.

I'll build a set of 6π cornerhorns later - hopefully this summer if $$$ allows.

I've got a question on insulation lining for the 2π boxes. The general instructions call for R-11 or R-13 insulation on the bottom, back, and side nearest the port.

Would 1" rigid rockwool insulation perform equivalently? I have some on hand I'd like to use.

Thanks

I don't know, Pete. I haven't tried the stuff.

I will say this: A few years back, I guess about 15 years ago, there was a push to change damping materials so I tried a few alternates. Some were purpose designed for sound absorption, others were just stuffing. My testing criteria was pretty simple, run some white noise and see which was most attenuated. What I found surprised me - Nothing worked as well as R11 and some materials were significantly worse. So I decided the old tried-and-true R11 was best and never looked back.

We're a few months after arrival of my components, but I finally got started!

Here's a build thread over at AVS. I'll put together another thread here after everything is up and running.
