In Reply to: RE: What amplifier do you use with your Magnepan .7 or LRS posted by MBerry6 on November 24, 2021 at 16:33:05
Does the way you've set this up:
1. run the LRSs full-range?
2. or have you implemented a HP filter on the LRSs to match the roll-off of your RELs?
In my view, #2 is the optimal way to implement subs.

I am currently running full range but would agree that a HP setup would be optimum. I am currently refining the Digital front end of my system but at some point I will explore the response curve in more detail.
I would be interested in recommendations on High Pass setups using LRS's with dual REL's.
Be aware you can't implement a HP filter on the LRSs if you use REL's "high-level" connections to the subs.The only way it will work is by feeding the output from your preamp into a 2-way active XO and then feeding:
* the low pass output into the low-level inputs (RCAs) on your subs, and
* the high pass outputs into the amp driving the LRSs.Using something like a miniDSP 2x4HD would allow you to play with different roll-off frequencies, to decide which delivered the best sound; I would suggest you start off at 24dB L-R @ 60Hz.
