I suppose concrete is an excellent sound absorbing material so nothing gets out of the sides and backs to muddy up the image. The port probably doesn't get all sorts of reflected energy, again to the benefit of imaging.

Just not in the main stream. -------------------- Creek 5350SE amp Creek Classic Tuner Shanling T-1000 CDP Bellari Phono Amp MMF-2.2 le TT Akai GX-265D r2r Epos 12.2 speakers Epos M-16s Onkyo Cassette deck Nakamichi LX3 Cassette deck

So, rather than absorbing better, concrete reflects better? Drivers better be primo or IMO, those concrete speakers have the potential to be bright.
