I owned two sets (the MX series for HT & the Revolution 3's for 2-channel). I still use the MX series in my HT and very much enjoy them. The R/L front MX 4's play down to the low 30's so the sub crosses over much lower (about 45Hz).
As far as the Rev 3's, they sounded fairly neutral (slight upper mid bump) and were easy to listen to in my analog setup. However, my listening room is 17 x 35 and open behind the wall they were up against (another 12 x 35) and even though the bass was tight and clean (down to the upper 30's), there just wasn't enough of it. I now have Kirksaeter 220's.
