There are unlikely to be any significant benefits if the glue is strong. Depending on the details of what you are doing 3/4" birch plywood may well be preferable.Are there any benefits in gluing 1/2" MDF sheet and 1/2" plywood together to get 1" sheet material to use in constructing some floor standing speakers ?
I'm wondering if there's any sonic benefits of doing this v's just buying some 1" plywood ?
How about damping between the drivers and baffle?If the cabinet handles midrange frequencies rather than just the low frequencies then the drivers banging about on the baffle will be driving resonances in the cabinet some of which are likely to be audible if not damped.
Damping? A soft spring to isolate the driver from the baffle can work well if the reaction force from the moving cone on the body of the driver is sufficiently small not to move the body significantly. This follows from the ratio of the masses. This tends to mean yes for a tweeter, perhaps for a midrange but likely no for woofers which tend to benefit from the added mass of the cabinet.How about damping between the drivers and baffle?
What best properties?I was going to hard glue the layers with the hope of using or combining the best properties of both materials in one sheet but i was mistaken judging responses on here. I'd heard that some commercial speakers were doing some thing similar ?
