Hi pmulvey,
Lots of excellent responses here, and I recommend getting creative (eventually) with subwoofer location. Mine is at one end of the couch as a quasi- end table. No-one notices it.
The M40ti is. . .I'll say it. ..tonally quite different from the M22ti, rather on the subdued side of the ledger. If you like clarity, transparency and lots of detail (and I do), then go for the M22ti. Its bass is quite pleasant on its own and you can add the extra octave of deep bass later on when you figure out how to cunningly conceal the subwoofer.
Regards,
