Welcome! Need support, you got it. Or share your ideas and experiences.

RE: total speculation. nt

The sandwich construction won't change the resonant behavior of the transducer at all. (At least not in the way I think you're thinking about it.) I've measured it.
I think maybe you're missing the objective of what the hardwood frames are trying to accomplish.

However, you are correct it will weigh more.....double the wood. But that's a good thing....IMHO.

The 1.6 (panel) doesn't have an impedance peak at 600Hz. Both elements are flat impedance through that range. The 1.6 'crossover' is what creates the 600Hz impedance peak.

A single-sided panel without screws and screw holes through the xducer should be possible. I considered that.....and am still considering it.

Cheers,

Dave.
