Good Listening

Peter is absolutely correct, maple with a bit of bracing is very non resonant and does a good job... I am actually refinishing the front of my cabinets now in Maple... the problem with maple is that it is tough to stain... that's why you will find it isn't used much.

Peter- Do you know of a company that is currently using solid hardwoods in their speaker cabinets? The last that I can think of were the Cizeks, made of strips of Koa wood, glued together for stablity. Even they used a plastic baffle board(acuthane, or something like that).

Rodman,

Properly finished Hardwood is very stable, Maple in particular.

Good Listening

Second the Corian. It's non-resonant and will not contract and expand, as will any hardwood. Reasons virtually no one uses solid hardwoods as cabinet material.

Sorry, I forgot to put my choice of baffle material. I like Corian.

Sometimes the screws loosen up over time on B&W's. I would check that first.

I do a lot of high end custom cabinet work for speakers. Contact me for more info at my username at gmail dot com

If you make the baffle thicker make sure that the mid woofer gets some berating room towards the back, consider making the opening through the baffle conical i.e wider as it progress through the baffle.

Thanks very much Peter! I intended to keep the height and width dimensions identical for the baffle face but thought to increase the depth of the face to reduce vibration and thought it might be good to shape the front along the Sa--n2 lines? I really had no thought of changing the overall box design, internal volume or stuffing material/quantity & shape -- and I wouldn't dream of changing the crossover. But I also had no idea of the relationship of the crossover to the dimensions and I appreciate your heads up. Very thoughtful & generous of you!
Basically I am just a listener hoping to reduce the gross deficiencies of the lightweight box and its vibrations. I hadn't thought beyond using laminated hardboard and MDF and painting the box black like the current boxes. Maple hardwood does sound like a nice step up.

Maple hardwood if you want only materials that can be wood worked.

Make sure you keep the front baffle the same width as it is now, also keep the drivers spaced exactly like original both horizontally and vertically, this way you will not have to redesign the crossover.

Also, keep the net internal box volume the same.

Best of luck

Peter
