what frequency are you liking best for crossing over to your M80s for music? 80-90-100?

I've gone back and forth between 80 and 60 and honestly cannot tell a huge difference between the two. I've never gone higher than 80.

Charles, the temptation is to say that by connecting the two subs together that you created a new path for a ground loop starting at their(separated?)power plugs. First though, how exactly did you connect them?

I thought you may have hit the nail on the head with this one, as I did happen to have a dimming light plugged into that outlet. However, unplugging it had no effect. Continued in next reply...

I tried this, and unscrewing it eliminated the hum. When I had the hum with just the EP600, unscrewing the ground screw actually didn't cure it. The balanced cable did. I guess this time the problem wanted another solution.

In my little bit of experimenting, turning on the subsonic filter also eliminated the hum, as did setting the crossover all the way down to 40.

Oh, I forgot to say thanks. Thanks to everyone who responded.

I forgot to respond, but I'll say you're welcome in spite of it.

I kind of feel like I should have been thanked for not responding.

Jason/CV,

I just got in last night and had about 1 hr to hook up and play a bit wit my subs. I don't want to say anything yet until I've had time to set them up properly. I do have one question though.

On the back of your speakers, what is the power draw of your sub amps? Mine say 675W (same as the EP500s). This seems strange to me since they are supposed to be 800W, and should therefore draw well over 800W.

I'll post more today as I have time to tweak.

Steve

The watts the amp puts out has no correlation to the watts drawn for power. Amps are continually made more and more efficient and I would not be surpriseed that a newer amp that puts out more would draw less current than an older amp.
