RM-30 w/Rel subwoofer - Crossover freq?
« on: 22 Mar 2015, 03:03 am »
Hi, I'm adding a Rel Q201e to my RM-30 2-channel setup. Wondering what thoughts are on a recommended crossover freq for the Sub should be? I have at 120hz right now.  Anyone else running sub w their RM-30s (for 2-channel)?

Thx

A Rel should be run just below where the mains drop off in your room.

Per the below, depending on your room measurements you most certainly want the crossover considerably lower than 120Hz

“The bass of the RM30 was very strong and punchy right out of the box; however, it rolled off just below 40Hz in my room after some initial positioning. I began with the side-firing woofers facing inward and later changed them to face outward, which I didn’t think made a huge difference. After a couple of weeks of positioning, playing the speakers, and removing a bit of Mortite from the front passive radiators (PRs) of each speaker, I did measure fairly flat response to 31.5Hz in my room. So the bass is quite robust and extends fairly deep. For my taste, I could take or leave a good subwoofer. Those that insist upon strong output in the bottom octave will require a good dedicated subwoofer system. The response does roll steeply after 31.5Hz and was down at least 10dB at 25Hz. I achieved these figures with the front plane of the speakers about 37 inches from the front wall.”

I also found that around 120hz sounds the best.  I have a large room though.  I have multi and 2 channel listening modes.  Both sound great at 120hz.
