Title: diy diffusers
Post by: BobM on October 28, 2012, 03:16:37 PM

I got inspired when I spotted these in the AC RMAF report from Pez and Tyson (day 3). They looked easy enouh to build. Some stained dowels and painted pine top and bottom. I don't need them floor standing so I can make a 4' tall version to hang on the front wall behind my Apogees. Hopefully they will make that front wall less of a "visible" boundary. In any case they should look better than the bubble wrap I have glued up now.

Here's a bunch hang drying (much easier to stain them this way too)

That's cool! Looking forward to hearing your listening impressions Bob!   aa  Reviewers of those shakti crueller candelabras say they sound great. The concept makes sense. You have 2 different diameter dowels?

I have the following sizes, all in 4' lengths

2", 1.5", 1.375", 1.25", 1.125", 1", 7/8"

it's going to be about 15 poles per diffuser in a pseudo random pattern.

Here's the finished product(s).  15" and a 20" panel to go on my front wall (no idea why they are showing up sideways here - sorry)

And them hanging in place

I'm glad I had the cutting and sanding done before the storm. This kept me busy for a while (and power is back now).

Those are interesting.  Any opinion so far?

It does look like the originals had a mirror image pattern:

Are there any links to the manufacturer?

I think the originals are Shakti.

They are essentially doing what I wanted - making the front wall appear to be farther away than it is ion actuality, presenting me with a deeper soundstage. So all in all I am pleased with the effort, and the look.

Bob,

If you do not mind what was the total damage in making the diffusers?

Thanks

A bunch of dowels in different sizes from Home Depot and Lowes, a 6' x 6" pine board for the tops and bottoms, a can of stain/poly and some black paint I had on the shelf and wood screws I had in the drawer. Only about $110 plus about 6 hours or so of labor.
