Best products for baffle material s ?

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.

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.

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

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