I know that...but in my opinion they cannot handle a whole lot of power....I cannot decide between the bl or the q. I want the speaker to be very musical. I want to be able to hit every note with authority (highs, mids, and lows....) I have type r's now in a ported box designed to alpines specs with a hifonics 2000 watt amp. I sounds okay but some notes it just doesnt hit. I have to find certain songs to find the right bass note to impress. I want to be able to hit ALL notes with authority....
