Hi dbbx0,
MisFit Toy is correct. When you are not running a subwoofer and you boost the bass that much with the bass control, you are asking the H/K's amplifier to deliver at least three times as much power at low frequencies (if you are using 6 dB of bass boost, which would approximate your setting of the bass control). The H/K's protection circuit senses too much current flowing through the output transistors and shuts it down to prevent it from overheating or blowing the output transistors.
Get a subwoofer!! And if you like really deep bass that much (most people do), think about the Axiom EP500. It's spectacular.

Hi again dbbx,
Good heavens! I just read your post again and realized the shutdown was happening when you used full bass boost. If the tone controls on the H/K give a maximum of 10 dB boost with full rotation (fairly common; check the specs), the H/K amp would have to deliver ten times as much power to the M60s at low frequencies. I'm surprised it doesn't shut down with 3/4 boost. Certainly testimony to the beefy output of H/Ks but full boost is asking too much.

M60's with the bass cranked all the way up must also sound like poop.
One of the things I love about the M60's is their clean, tight bass. Mucking with the tone controls/bass boost is going to turn that tight bass into a muddy, yucky mess.
Start saving your pennies and get a good sub.

Thanks for the advise. I am definitely getting the subs but like I said, I am waiting till I get my hometheater down to the basement (just finishing mudding and taping right now). In two months I should be able to. I just can't get the subs now because I would like to make sure that the subs that I will be getting will be enough for the basement. I can't get the subs now and return it after two months. I only have 12x10 room right now.
For now I just wanted to make sure that I don't have a mismatch problem between my HK and axiom speakers.

Just so everyone is on the same page, are you saying that it only shuts down when the tone controls are set to full bass boost ?
If so, I guess the consensus message is "yeah, no surprise, turn down the bass boost "

The bass boost on my receiver...ok I'm not even sure what it's set too... I think +3? out of +6?.... although if you check my individual speaker settings, the sub is at +2.5, this setting goes all the way to +12...
cranking it high = death to receiver.
it's that simple.

EDIT: I just checked... my "Bass Boost" (that may not be exactly what it's called" is at 0db! not even on! eek .. I have a powerful sub

OK, now I'm really confused. Subs are normally self powered, so turning up the sub output level should have ZERO effect on the receiver.
Daphoid, you're confusing us... unless you're the same person who started the thread. Turning up the sub output level = instant death for the receiver ? Huh ??

Ok, my receiver, can control bass boost across the board from -6DB to +6DB. it ALSO can control the output of my subwoofer pre-out, from -12DB to +12DB, FINALLY my subwoofer has it's own gain knob which affects it's volume as well
Basically the only setting the original poster should be woried about (since he/she has no sub) is the "bass boost" or whatever the receiver calls it, boosting the bass to all the channels = BAD as Alan mentioned.
