A plate upon which to build and isolate a crossover network

jeffreybehr

I'm rebuilding the x-overs of a pair of Serenity Super-7 speakers. See
http://www.audioasylum.com/forums/MUG/messages/21/219948.html

The plate that the original x-over is built upon is probably 3/8" fiberboard; it was screwed to the top of the H-box in which live the two open-baffle woofers. I'd like to isolate the x-over components from the vibrations of the bassbox by building a very-hi-mass plate upon which I'll mount the components and which I'll suspend in some manner from the bassbox...perhaps with Herbies Baby Booties.

After I spread the components a bit, the plate will be 11" wide and 13" deep. I priced half-inch-thick glass plates at about $110 EACH and 1/4" brass plates for about $125 each. After recovering from that sticker shock, I priced 3/8"-thick glass plates locally for TWO for $51. That caused me to overthink a composite plate of 3 sheets each of glass and SoundCoat the Thicker...

...starting with SC on the bottom and glass on the top. It'd be a bit over an inch think and ought to weigh a substantial amount and be quite dead acoustically. I'd hotglue the components to the glass top and place the plates/crossovers atop the Herbies Baby Booties atop the bassboxes.

What you think? Overbuilt? Over paranoid? Who the hell could hear the difference between the original (free) 3/8" board and this monstrosity? Great idea--I wish I'd thought of it?

One thing--pls do not suggest I mount the x-overs outboard. I've done that once...

...and it made the speaker system VERY difficult to move.
