    Quite pleased with the purchase.More than decent sounding speakers. I would say that for the money u can't really hope for more than this. Used full GRS line of speakers to rebuild old pair of floor standing speakers I had and it turned out pretty descent. Used 2 of these in series plus one GRS 5SBM1-8 Replacement Mid-range Woofer for mids and a GRS BT3-8 Bullet Tweeter for highs. Had to cut down the tweeter a bit because it was outshouting everything else due to the higher sensitivity, but after putting one extra capacitor between the filter and the tweeter I got myself a pair of quite nice 8ohm floor standing speakers to go with my Denon PMA-700AE amplifier. The only real downside is the relatively low sensitivity - other than that you get a lot of bang for a little of your bucks, simply superb ultra budget speakers.
