I recently purchased a pair of M22s as my main monitors in a 8X12 sized room. They sound great on an old stereo receiver. To upgrade my system, I purchased an Onkyo TXDS 494 receiver along with a Hsu VTF 2 subwoofer. The
Onkyo does not seem to have a selector for "large" or "small" speakers. I plan to use the high pass crossover on the Hsu where I would connect the subwoofer to the main L & R speaker inputs on the Onkyo and then connect the M22s to the subwoofer. Hsu Research describes the high pass crossover as "speaker level - 6 dB/Oct, approx 90 Hz with 8 ohm speaker." Will doing this be detrimental to my M22s?

The set up you have in mind would be alright for 2 channel music listening but for home theatre or any multi channel listening I would suggest you hook the sub to the line level sub output on the receiver. Running the M22s without a x-over in the low end is not a problem.

The Onkyo 494 does have a large and small speaker option (with crossovers at 80 and 120 hz, respectively). There is a subwoofer control button on the front panel that has three options when you press it: off, large speakers, or small speakers. If you have a sub hooked up to the pre-out I don't think it's even possible to have power to the sub without either large or small speakers being selected. hope that's helpful to you.

what crossover do you recommend for the m22's?

I recommend you experiment in your room. The M22s will run great on either the large or small setting on the receiver.
