Default eah, thanks for the tips!!!

I have an old junky table saw in my kitchen that I use from time to time. It could probably use a tuneup. it would make my projects look better too no doubt.

course, I am usually just aiming for an end sonic result. I have eventually found that selling my experiments to friends at modest prices allows me more feedback, a little cash to cover parts expenses, and keeps the clutter down in my apartment.

so getting a table saw right is important for me right now...

I've done a little research at Home Depot.
They sell PL premium construction adhesive, my favorite glue. It is $3.89 in the glue section. It comes in a caulk gun tube.

They also sell removable weatherstripping called "Seal and Peel" made by DOW it's $4.29 and is in the same section. I use this both for speaker gasket, and to temporarily put a face on a cabinet for testing that I'd like to disassemble later.

2" PVC is available in 2' lengths for only $2.69

Very interesting,

I wonder how this driver would preform in a linear array of 3 or 4 units per side?[grouped in the same cab.] parts are priced right. Any opinions? and can it be modeled?

Does anyone know how well this speaker would work if built out of, say, acrylic?

Acrylic sheet as is "plexiglass", or the acrylic based mineral filler laden solid surface materials ( i.e. Corian, Avonite, etc.) ?

Due to the cost and fabrication intricacies, I've yet to hear any DIY speaker made from the latter, My only audition of a commerical (Full range) product was quite underwhelming .

Corian has been successfully used in a similar design. I think thick acrylic could work, but I don't think it would outperform 3/4" MDF.

I don't know about that... IMHO MDF is not a great speaker building material (unless you are a speaker manufaturer trying to keep costs down)

I don't know about that. Some of the most expensive speakers in the world use MDF. I believe the Wilson Watt Puppys are partialy MDF. I agree with you that MDF is generally hard to design with and I have not gotten good results with MDF but many extremely high end speaker designers are using it. In the end, these guys are not worried about an extra hundred bux for wood in a 40,000 dollar speaker.

Another reason mdf is used is because of dimensionl stability and milling qualities.
