Maximo, if I recall (and my mind is getting hazy in my old age) but those have the 15" woofers correct (or is it the 12's) anyway if it is the 15" those require a tad bit of power to drive when played loud. I recall those could only handle 100 watts and were 84db @1 watt/1 meter. So your HK amp may not have enough juice to drive to insane levels with those huge woofers. You may want to buy a stereo amp to drive those monsters.
Another thing to check are those Piezo tweeters. I recall that I had two pairs of those speakers and I gave you the good set and sold the other pair to a pawn shop and it had a faulty tweeter which would distort. They can be found online and are really cheap. Either that or turn it down you young whimper snapper.
Amd about those "sexual favors" I'm still waiting there Big Boy.
