Re: Re: Re: Re: Ply the music out..
Your speakers maybe, not mine. Nicely politically correct, BTW with that comment.
Here we go again...
All of my earlier efforts as far as speakers go are long gone. Even some of my recent ones are burned. I keep the drivers, but if I'm not satisfied with the box, I trash it.
The first time builder should practice on cheaper materials, not break the budget on over-priced plywood.
Buy better drivers with the money saved.

That would be your slanted take on it Dave. My tests were very revealing and executed as I originally preposed. I will redo these tests at some point in the future (months) with ARTA as the measurement suite and revamped setup/equipment.

You guys are lucky.
Around here a sheet of MDF is around $25, cheap grade 7-layer ply with lots of voids is $40-$50 at Lowes/Home Depot, cabinet grade ply is around $80-$100 and the premium 21-layer baltic birch is over $200 for a 4x8 sheet.
Most of my projects are done in MDF, with the cabinet grade ply reserved for "special" projects. I have yet to buy a sheet of BB.
I have no problems with MDF sonically, but the dust sucks and it's much harder to finish than just slapping a coat of tung oil on some nice ply.

I live in Washington state as well, and cabinet grade plywood is indeed, three times as much as MDF. And your right, wearing a mask during the cutting is going to reduce any health risk, as well as hearing protection too!
I tend to recycle old cabinets from pawn shops (if they're in decent shape) and most of the ones I find are double sided veneered, high density particle board, not MDF, or plywood. They sound fine to me. If I could find a good deal on quality plywood, I'd use it, just because it looks good, but until then, I'll use whatever's handy.
I would always use good quality ply for PA and MI cabs, it certainly wears much better and is lighter than MDF. However, I re-iterate what I said in the earlier threads, for home use with bigger horn type boxes with unsupported large panels, then the resonances of MDF may be troublesome, but, in my experience, for more conventional well braced boxes then there is no difference.
Hello,
intresting Thread!
So, what do you think about Spruce? If you believe Charles Altmann, it is the perfect material.
Does anyone have any experience with Real Wood like Spruce?
Greetings
Mike
