Best products for baffle material s ?


Looking for the "best" combination of materials. Building new boxes for my B&W CM1 bookshelfs as I can feel vibration on the baffle and sides, with classical music, quartet, at even very modest volume. These are very small 2 ways - so I can afford to go "all-out" on the boxes. High mass, inert, shaped baffle to minimize diffraction, interior design to break up waves. I'm considering only products that can be "woodworked". More detail later. Thanks.

Rodman,

Properly finished Hardwood is very stable, Maple in particular.

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

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.

The front baffles on most of these are made form laminated hardwood, most from 1.625 to 2.125" in thickness. The back cabinets are made from MDF which is veneered then finished or finished in automotive paints.

Rodman,

The width and length of the baffle is an integral part of designing a crossover for a speaker. I'd make sure that especially the tweeter sees exactly the same boundaries as in the original design, if the same x-over is to be reused.

I'd agree that rounding over the edges on the front baffle probably will have minimal effect. However don't go making a 7 inch wide baffle 12 inches wide.

Best of luck

Timlub,

I think Theil and Hales tried that years ago. Then there was the Swedish Rauna and the Danish Avance companies that made the entire enclosures out of concrete. All had a difficult time making any finish stick to these because of the alkalinity of concrete as it cures.
