Cerwin-Vega CLS-215. These are not just your dad's frat-boy speakers. The high end press has taken serious notice of these monsters:
Soundstage review
Soundstage measurements. Notice how uniform the response is at various levels of amplitude.
TAS review. Yes, a favorable review of a 2x15 Cerwin-Vega speaker from TAS!
Yet they are also around 93 dB efficient, are bi-ampable, can handle something like 500 watts, and easily reproduce strong bass down into the 20's. If that isn't a rock speaker, I dunno what is.
