Need Help Filtering

post #1 of 7
Thread Starter 
I've recently acquired a set of Martin Logan Motion 4s, a Martin Logan Dynamo 300 sub, and a Harmon Kardon HK-3490.

I was wondering if anyone would have any suggestions on how to set up a low pass filter. Everything sounds great, but while watching movies, I can hear the Motion 4s straining to hit the low frequencies.

I knew going in that the HK-3490 didn't have any bass management, and everything sounds WONDERFUL while listening to music. It's obviously different watching movies, though, and I'd like to get that all sorted out.

So...any thoughts?

Since bass nob on the HK 3490 adjusts both the main speakers and the sub you could back off the bass on the reciever and increase the volume and the high-pass the sub. I am probably wrong though.smile.gif

I realize that I said I was looking to do a low pass filter, when in reality, I'm trying to set up a high pass filter for the fronts. I'm not too worried about the sub, since it has it's own low pass filter.

But you seemed to know what I was getting at. I'll have to try that when I get home. In case it doesn't work out, are there any other ideas?

A stand-alone sound card would (should) have bass management.

Well I've got an Asus Xonar D2X that has great bass management, as well as using J River. My thing is that I wanted a good way to use the sub through the receiver as well. I guess it's not a bad option, it just seems a little tacky to me, and the fact that the volume control would only control the fronts and not the sub would slightly bother me.

I don't know. I guess whatever works. I don't want to spend the money if I don't have to, but if it means not blowing my new speakers, I'll do it.
