Room Acoustics

Just tested my media room using the Rives test disc (pink noise) and a RS analog SPL meter.

Couple of things:
- I kneeled behind the meter, which was set on a tripod in my so-called sweet spot for two channel. Certain midrange frequencies were very sensitive to my location and movement.
- For the heck of it I put some FG acoustical treatments (4'x2') at the first reflection points. Plotted the data and found that it impacted some frequencies but appeared to create more spikes a troughs than without!

I am interested in how some of these room treatment companies can quote you a package without measurement!

I'm going to repeat the test from all seven seating locations. Expect to see some wide variation.

Sean, have you played with room correction electronics (e.g. the TacT system)? If so, how would you rate their performance over standard room treatment approaches?

Finally - to everyone - why is there such a bias against such systems?

Thanks,

Dave,

First, cool system! Love it. Second, that's what I see: room treatment is - at best - shotgun accuracy; contrast that to what these RCS systems can do (rifle accuracy) on the linearity of the response! On paper, amazing.

I'd love to compare a spectacular system (e.g. Mike L's or Albert Porter's) before room treatments with RCS and after room treatment (or construction, in Mike's case) without the RCS.
