Hi,

May I ask, what is the model no: of the new Onkyo AVR that you have? I ask, as being a new/newer model, I am a little surprised that it does not offer you the option of of setting the sub's crossover on it, especially since it seems to have Audyssey? Maybe others more in the know can chime in in this!

I would set the X/O at the back on the sub at 150 as Audyssey suggests - it seems about right although if the Mirage sub settings go higher, play around between 150 & possibly a little higher if need be.

Bazzy,

It is an Onkyo TX-NR616. It came out in mid 2012 so it is a little older. This is kind of an in-betweener purchase. I wanted to get a receiver that is full 4k ready, like a Denon X4100 but can't justify the cost when there isn't much if anything using this, and I don't have a 4k TV yet. So, I found this one on a closeout and I had been wanting to try an Onkyo, so this receiver fell in my lap. I have to say it's a pretty big step up from the Denon 988 I had in terms of sound and picture quality. Pretty happy with it so far.

AVRs have had adjustable crossover frequencies since the 1990s, maybe earlier.

Here's an excerpt from the manual, page En-34: "With the supplied calibrated microphone, Audyssey 2EQ® automatically determines the number of speakers connected, their size for purposes of bass management, optimum crossover frequencies to the subwoofer (if present), and distances from the primary listening position. Audyssey 2EQ then removes the distortion caused by room acoustics by capturing room acoustical problems over the listening area in both the frequency and time domain." If you don't want to do the Audyssey setup, you should be able to set the speaker setup (page En-54), set subwoofer to Yes, and speaker crossover from "full" to 120 or 150 Hz.

The Minx Min 21's (similar to your 20s, though slightly better at the low end) volume drops precipitously below 200 Hz, and by 100 Hz it's down about 12 dB, which is a little less than half the volume, but definitely audible. The smoothest transition would be at 200Hz, but that's not ideal: most subs do poorly that high and the sub's location would be very obvious. A better balanced crossover frequency to 100 or 120 Hz, preferably 100 because at 120 Hz you can localize the subwoofer.

Experts, correct me if I'm wrong but IMO, the combination of the speaker's natural dropoff and the crossover's cut would create a sheer dropoff in the speakers' volume below the crossover frequency, so when I get my Min 11s, I'm planning on setting the speakers to "full" to preserve what bass the speakers produce, and simply set the subwoofer's crossover to 100 or 120. Will I have a valley between 100 and 150? Probably. I'll play with it when I get them.

Thanks for that great information! I did run Audyssey and am using those settings. So if Audyssey set the speaker crossover at 150 am I right to set the crossover on the back of the sub to 150 or do I disable the crossover on the sub?
