ultimate AV has a review of the ClearPix2 acoustically transparent screen by Screen Research. The screen lets sound pass through, so you can place speakers behind the screen. I am considering this approach once I make my first million and can build a custom home theater. But seriously, having three speakers across the front that are identical (not like most people who have with a sideways center channel speaker) is actually the way to produce the best sound. The store where I bought my receiver (Dewars) highly recommends this approach, and it’s what movie theaters use and THX recommends (if I remember correctly). Using an acoustically transparent screen is one way to accomplish this.

Their ClearPix2 has already received certification from both THX and the Imaging Science Foundation (ISF). It is not perforated; instead, it is woven using microscopic fiberglass strands coated in vinyl and then woven in a propriety and patented knit design. It’s also available in all of the most popular configurations, including fixed and retractable. A variety of masking systems are also available for both fixed and motorized applications.

The choice of any screen involves compromises, either audio or video, and sometimes both. But in my experience, the advantages offered by the Screen Research ClearPix2 are significant and well worth considering for those who want to get the undeniable advantages of locating one or more of their front speakers behind the screen. It’s not without its own tradeoffs, but with the right choice of projector and screen size, I highly recommend it.
