What are those items that appear in your sig? Are you selling those?
In thinking about acoustically treating my future theater room, I'm planning on 1" absorptive material (Linacoustic?) and diffusive material (???) behind a stretched fabric wall of some sort. Does the fabric used in front of these absorbers need to be acoustically transparent? Obviously, in those areas where the fabric will cover my in-wall speakers, the fabric will have to be acoustically transparent, but does it make any difference for the 95% of the wall that have no speakers?
On a related note, in browsing the Guilford of Maine web site, there is a whole line of what the term "Acoustic Fabrics". It seems that the gold standard according to AVS forum is the FR-701 style. It appears to have very little effect between 250-1000 Hz with a gradual rolloff at the higher frequencies.
What would one expect with some of the other fabrics in the GOM Acoustic linup? I'm looking at their Anchorage product. If I'm interpreting their performance graphs correctly, it appears that this fabric seems to have more attenuation across the frequency band and a little more relative attenuation at the higher frequencies compared to the FR-701. Can this sort of performance difference be compensated for by level adjustments and mild equalization of those speakers that lie behind this fabric?
Other fabrics of interest are their Sensa and Coastline styles. Sensa appears to have even better acoustical performance than the FR-701 below 250Hz, but still has the high-frequency rolloff as seen in the FR-701 graph. The Coastline style, in contrast, seems to have more attenuation, but at a more linear pattern across the frequency spectrum which to my mind seems like it would be more amenable to simple level adjustments as opposed to level and equalization adjustments. Are my interpretations of these data graphs accurate? Is my characterization of the types of adjustments that could be made to optimize the acoustic performance of these fabrics in a typical HT application valid?
Thank you, greatly appreciate, it shows integrity!
I see, thank you.
So I read that having a book case in the back is a good idea?
