I have stereo amp, KEF R3 and REL t/5x. I use Roon as well. My plan: connect t/5x by high level connection. Crossover t/5x at 60Hz and turn up the t/5x volume. Then I measure the sound and I’ll see 20Hz to 60Hz are too high, so I apply convolution filter to Roon to press down that range. More I turn up the t/5x volume before applying convolution filter, more the portion of volume I’ll distribute 20Hz to 60Hz to t/5x. It’s another way of doing “high pass filter”. I know it’s not the same, and it’s not the philosophy of REL. Do you think my plan would work? Any drawback you can think about?
Yes, it should work. It is similar to how Vandersteen subwoofer integration implements a compensated high pass scheme in the analog domain.
But the drawback is that this method reduces headroom, putting much greater demands on the subwoofer amplifier and driver. A REL might not be a good fit.
