Default Zaph SR71 Build in Concrete

I threw together a pair of SR71's in concrete... They weigh about 55 lbs each (just box) and are 1 inch thick on all surfaces. Cant feel too much through the box when they are playing. Kinda look a little industrial with the bug holes but I can't argue with the sound that comes out. Pretty good speakers for the price.

Neat build. I'll second Paul's request for build pics.

This reminds me of a pair of bookshelves I saw years ago made with besser (cinder) blocks with part of the centre divider ground out, and front and rear baffles glued on with construction adhesive. Beyond the driver and xover cost, total investment was about $5. Didn't look as good as erpiii's though.

Please do not mock the Big Merino, it is a significant cultural icon down here.

That image is a bit big, Pete.. Could you reduce it by , say 40%, please. ?

Oh and yes, it would be interesting to see how those concrete (or is it cement) speakers were built, please.

I think the thing that would worry me most about concrete or cement would be chipping of the corners. (apart from getting a sore back, of course )
