The M2's are not going to offer that enveloping surround experience to the degree of the QS4/QS8 (due to their quadpolar design) but certainly the M2's can be used for surround speakers.

For A-stock items especially 1 pair, they usually ship out within 48 hours or less so the wait shouldn't be too long. If you ordered from the factory outlet, there is waiting period.

Congrats and enjoy! Looking forward to your impressions.
