I started this thread debating the idea of upgrading from M3's to M22's. I received the M22's last week and prefer their sound in my system. Good recordings sound great...poor recordings sound poor. They are not a speaker to make a poor recording sound "okay." The sound, though, on good recordings is so good that I will continue to search out good recordings to play on them.
The M22's mate well with my Dayton Audio 10" sub. I have the M22's connected to the speaker "A" terminals of my Onkyo A9555 integrated amp. The sub is connected to the speaker "B" terminals of the amp with the subs crossover set relatively low...probably around 60 hertz. I then run the amp with speakers A + B. I emailed Doug Schneider of the Soundstage web site and told him of this setup. He commented that my sub setup was less than ideal. It maybe goes against convention, but I like the sound of letting the M22's run full range (no cutoff)and have the sub fill in just the lower registers. It sounds great.
