In addition, the PLRL572 trumps over previous models such as the PLRL52 and PLRL462 by supporting a much improved 200w peak power output (versus 160/180w) and 100w nominal power output (versus 80/90w). In addition, the PLRL572 offers a superior frequency response of 50Hz-20kHz (versus 55/66Hz-20kHz). The PLRL572, however, maintains its predecessors’ 1” hi-temp Ferro fluid enhanced voice coil, 1” Mylar dome tweeter, and rubber magnet boot cover. The PLRL572 is priced at $36.50, approximately $2-$3 over its peers.
