Considering their price, seems like they would make a good buy for a poor but honest old duffer wanting to boost the octave around 30 hz for an outdoor system (stereo) using quad A-7's in each channel. A pair(of LS1802's) would cost about $1100 plus, say, another $1200 for a DCM4000 amp to drive them. That's $2300 amp and all vs, say, $2200 for just one 12pi sans amp. -Dick
