I have been lookin' to add a sub to my system. Many of the subs don't include a high pass xover. Is that a feature that is important to have on a subwoofer?
Here is one that I have been eyeballing!
Thanks much!

You can get a high-filter with the Rythmik F12 Servo Subwoofer. The A370PEQ amplifier can be purchased with either LFE inputs or else HPF outputs. Check it out at the link below.
Bad design. Many high level sources don't have high pass filters. A sub should have one or else I think it's poorly designed. With no high pass power is still going to your main speakers and being wasted. And you would have greater level ability in the main speakers without them being attempted to be driven.
High pass filters alter phase response. If you own linear phase speakers like mine, you wouldn't want to use a high pass filter. I just run my Thiel CS3.7 speakers full range and let my Rythmik servo subs reinforce the bottom octave. The inclusion or deletion of a high-pass filter has no bearing the design of a subwoofer. Rythmik servo subwoofers are some of the very finest subwoofers available. Furthermore, the inclusion of a high-pass filter was optional on the model I bought. I didn't want it.

If you can swing the F12 over the L12, the parametric EQ is a great feature.
Spoke to the Tech people at Rythmik at that is what the recommended for serious audio. The trouble is that the amp best suited is not available and is on order.
Put the line level high pass filter on the cables from your preamp to amp for the mains.

I see that,thanks!
I have a Rel Strata III that does not have a HP filter. This is fine for me as I run my Magnepan 3.7i full range and just use the sub to fill in the bottom octave (LP filter set to 38 Hz). If you want to take the "load" off the main speaker then an HP filter would be needed - most HT processors provide this but the standard stereo preamp does not. If you need/want a HP filter, insertion of a single cap (C= 1/(2*pi*f*R), at the input jack of the amp, will suffice (R= input impedance of the amp and f= desired frequency).
I married the perfect woman. The downside is everything that goes wrong is my fault.
Thanks for the info! My Harbeth's roll off at 80 hz,so I would adjust the low pass on the sub at 80 hz and it should work full range without a high pass filter.
