a pair of Harrison Labs FMOD in-line 70Hz high pass attenuators would do an excellent job of rolling off your LRSs (and I suggest will be exactly right with your current 60Hz sub setting).They seem to be 12dB.

Thanks for the suggestion. I almost went for a set of the cable FMODS. That would have given me the flexibility to use 50 or 70 HZ and may have worked out for my system with the (now in need of repair) ProAcs. I like the packaging of the in line units better.I will let you know how it works out.

That will be interesting to know. :-))

Has anyone tested these Harrison Lab filters? I remember reading in a car stereo magazine several years ago that did a review of them. It turned out that the advertised 12dB/octave slope tested at being only 6dB/octave.

I use a set of 100HZ in my trunk to roll off my car stereo's tiny rear fill tweeters.

100Hz?
If they're tweeters , I wouldn't have thought they actually go down to 100Hz.

They are actually advertised as 3-1/2 in two way full range marine speakers, but they puke up any input signal below 100Hz. They only add a little fill so the sound is not all from the footwell.
