Further cleaning/purging of the gear to help empty out the house.

These are prototype diffuses from when I was experimenting with different materials and assembly methods. The big one isn't well finished, but is to the correct math and measurements (and a big PITA to build).  The two "smaller" ones are poplar and would look amazing stained.

They are too big to ship really, so pickup, or possible delivery  in the Chicagoland area. Ping me if you are interested.

The largest diffuser is a HUGE  33" x 48" by 12" deep QRD 29 (meaning it's a non-repeating prime 29 sound diffuser). It's very broadband, more than most anything else on the market. It's a prototype, so it's not perfect, but it's only $100 for a huge diffuser!  It's heavy, around 65 pounds. Made from Plywood, MDF, and dense polyfoam for the well bottoms. Glued up with special adheasive made specifically for this type of foam.



The Middle sized is an all hardwood (poplar) QRD 11 sound diffuser. it's roughly 36" x 24" x 6" and ready to be sanded and stained, or painted. $100



The smallest is also an all hardwood (poplar) QRD 7 + 1 diffuser, is roughly 25" x 24" x 6" Ready to sand and stain or paint. $100

Sorry for the poor lighting, but this one is just a slightly smaller version of the one above. Same materials.

Thanks JD!

The bigger QRD 29 isn't built up to my standards, it was a pain to build, but it is the most effective and broad band of the bunch. The two Poplar ones I'm actually very happy with and was asked to make more to be displayed at Axpona last year, but had some family stuff that kept me from cranking out a dozen of them and maybe being a professional builder.

I'm hoping someday when my job situation settles, I'll be able to crank these out for myself, and locals (because they are too much to ship).

And, IMHO, diffusers do far more for sound that absorption only.

But I agree - I have a folder on my computer filled with great diffuser installs for good looking ideas.

Hi Lonely, I sent you an email regarding the diffusers and some of the absorption panels as well. Thanks! - Matt

Still available - I've had a couple no shows who've wasted my time, so diffusers are still available.

Also, how about a package deal. I'm pulling all the diffusers off my back wall, plus the three mentioned previously, plus one partially assembled one I still have in the workshop (poplar, all parts cut already) for $300!!









Hit me up if you're interested!  

Sorry, I've been on a business trip, and didn't see your message till just now. I've responded, and all the diffusers are going to Matt, pending payment!
