Monitor Audio FB210 or REL Strata ?

Thanks for reply. I've the old Monitor Silver 8i's and Freq Res is 35Hz - 25KHz + 3dB. FB210 is 40Hz - 140Hz High level and 25Hz - 140Hz + 3dB. I don't want picture shaking sub because of wife factor involved. The room is big about 20x15.
REL LOWER FREQUENCY RESPONSE AT -6dB: 18Hz. If I hookup both high and low pass as REL recommends, I should be fine I guess. Its a musical sub but at the same time less picture shaking. I think I'm leaning towards a musical sub. Price is factor too, $995 for FB210 vs $1295 for ST vs $1595 for Q.
I'll check the Rega too.

Thanks very much. I think I'm going with the REL. I need to buy a black finish, so can't find any as new REL, but I've dealer for REL in my area, will get a new one. Also as you have mentioned, resale value.
