Maggies with a subwoofer system - optimization?

I need advice on how best to improve the midrange and base on my Magnapans (1.6qrs)My idea is to relieve the panels of base duty ( only feed the signal above 100 to 150 hertz to the panels and let my Swarm subs take the low end signal). I assume my midrange will improve, and the solid base performance via the sub system will fill in well. I now run a Krell S550i integrated into the Maggies, and the Krell Pre output into the DaytonAudio SA1000 Subwoofer amp.

Any feedback is appreciated - will I lengthen the life of my panels? Am I wasting my time?

How is that done without a high pass filter between the amp and preamp? Just curious!


@yogiboy  Unfortunately you have found the problem, you can't. :)

Adding a subwoofer without also limiting the amp output will not reduce the load on the main speakers at all.

Hi Tom,

Your cutoff target may be a little high, I’d suggest around 80 Hz instead.

Your approach is good, but you would need to limit the signal before the amp. This would greatly increase the dynamic range of the amp and panels, and yes, reduce the strain on them. I’m not sure if it will improve the life of your panels. That depends on how they wear normally and how much bass you were going to push them to begin with.

The best advice I have for you however is to rely on automatic room correction to setup the crossovers and EQ, if any.

Best,

Erik
