Open Baffle Planar servo sub speaker project

Sorry for the spellchecker errors!

If I can get them, 8- NEO10's and 22-NEO3PDR's per side. Each NEO10 and each pair of NEO3PDR's will have their own amp modules for beamforming. Only time will tell if they are available.

Tough to find them in a #4 size screw around my area. I do use hex heads for the larger ones.

Check out this link. McFeweley's is a great place to get screws,

Tom,
Thanks! Will give the #4-3/8" a try with the square drive.

Just ordered 200. Should be enough for awhile.

Received my Pocket CLIO system from PE today and set it up on my Netbook running Windows 10 64bit OS. Took the frequency response measurements for the open baffle planars using the BG NEO3PDR and NEO10 planars with the 6x12" servo subs. This is an overlay of the midrange and tweeters crossover responses.

Once I get the FPS line arrays running will see what crossover is needed with them.

The BG NEO3PDR planar tweeters went on sale this morning at Parts Express.

They are on order and should be here in July. Then it will be time to build the larger line arrays.

This months Parts Express magazine has an interesting article by Don Keele about the CBT array with beam patterns above a ground plane. I have multiple copies if anyone is interested in one.

Here is a link to Don's website where you can get not only the CBT info but his other papers as well. He also received a technical Oscar for his work with horns in motion picture sound. I've known Don for years and he is not only a very knowledgeable guy but a first class person as well. He may be a judge with me at this summer's Midwest Audiofest speaker building competition.
