"I have owned the original B&W 600 series speakers since the mid-90's, and they have been serving me well for all these years. My setup is comprised of DM640's for the FL and FR, a 600IFS center channel, the original DS6 dipoles, and an AS6 subwoofer. I also have a pair of DM600's that have been boxed up for years since I don't have a good place for a set of bookshelf speakers anymore (they used to be my surround speakers before I bought the DS6's). I actually have a second 600IFS on-hand as well - for the past 15 years I was running two center channels with my Denon AVR5600 receiver (it had two sets of binding posts for center channels), but I just took one of them out of service last week when I picked up a used Denon 4806 AVR to replace my 5600.
OK, enough about my setup - here is my question: the new AVR supports 7.1 channels/amps and I want to set up my family room for 7.1 surround. Due to the space constraints and the room layout, my wife is adamantly against hooking up either the DM600's or the spare 600IFS as surround back speakers. That being the case, I am strongly considering picking up two of the new M-1's to use for surround back speakers, although it kills me to drop $500 on two new speakers when I have old ones on-hand . Does anyone have any idea how the M-1s may sound with my ancient 600-series speakers? Has anyone paired the M-1s up with other B&W speakers in this fashion? I've listened to the M-1's at a local hifi store (as well as BestBuy) and I was surprised at how good they sounded, so I'm hoping they would make a good addition to my home theater, both for surround sound and for using Denon's 7-channel stereo feature. They should fit into the space fairly well, and would be positioned about 4 feet directly behind my couch where we watch TV.
Anyone have strong opinions about the M-1s for this purpose? Any feedback would be appreciated..."
I recently purchased a pair of the new M-1's as by rear surrounds. I have a setup with older Tannoy's front and center and Mk surrounds and sub. The M-1's were a great addition and work wonderfully with my setup. I would compare the Tannoys favorable with your old B&W's based upon listening to the current 600 series at Best Buy but I have no other reference. I would note that while comparing the new M-1's with some 685's while watching a movie at Best Buy the 685's struggled when played at high volume on the depth charge scene in U-571. The M-1's handled flawlessly. Used a Marantz 6006 and a Pioneer SC-55. I have the marantz at home.
