No one can help me? My favourite musicstyle is techno, so the bass needs to be fast and powerfull (not sloppy). I have tons of woofers I can recommend, but you're using way too much power for all of them...frankly, most people that are using small box, sealed woofers have no use for 1.5kW. It's going the wrong way down Hoffman's Iron Law... Uhmz... Weird, back when the old RE XXX (mark 1) was on the market, it was very power hungry. I only powered them with approx. 800W RMS each in a sealed anclosure. But I could even feed them 1600W RMS each without problems. Well I will wait a few days and see if someone else can come up with a good idea. Otherwise I will do some more research on which subwoofers to buy...
