Cabinet

Not worried about the vibration,I can work that out. I’m concerned if there would be any unwanted frequencies from the porcelain? I also have the ventilation covered.

I thought maybe it would have effect the sound & or video output/input in some way.

Thanks to all who replied!
With a lil labor, the doors have raised panels that I will be replacing with speaker grill cloth, & install a fan in the top rear of the unit. My existing unit doesn't go with my decor. I figured this will be strong enough to house 2-amps, 1-pre, 1-Pioneer sx1280 & miscellaneous gear. Total about 300 lbs. plus.
