TITLE: material for QRD well coverings
QUESTION: is 1/2" birch VENEER plywood *** ACOUSTICALLY *** acceptable for covering QRD wells or does it have solid?
A website that sells plans for a QRD build recommend using wood:
"We use a lot of cherry wood in our diffuser builds. Softer woods are good selections for a sound diffuser material because remember sound takes on the characteristics of the surface that it strikes. If sound strikes wood, you get a nice, smooth, warm, balanced tonal quality sound back into the room and that’s why I always tell people that a diffuser is a musical instrument."
In researching the availability and prices of recommended woods from online or local sources, cherry is $160 for his unit size of 1/2" x 2"W x 27" from a local source, alder is unavailable locally or online, basswood comes in 3 pieces of 3" x 24" for $33 (making it $11 per well width for a 24" instead of 27" long well; the 7 wells would be about $77) and 1/2" x 48" x 96" common birch plywood costs $48.33 from a local home center which can be cut into multiple well widths, about $3 each. The 7 wells being then about $21
Therefore, can the VENEER reflect the sound in the well just as good as the SOLID basswood?
And is birch just as good as the more recommended basswood?
The cost savings is significant especially since multiple units need to be made.
Thank you
PS let's talk acoustical science, not about the acoustician who made the claims about the wood matetials
