My current HT is 5 AR.Coms. I didn't have the need for a MTM center because my TV is projection vs CRT. Of course they match well because they are all the same. If you want to hang the surrounds off the wall then IMHO, my two new designs will meet your purposes. The RS150+MDT20 is an outstanding value. The only thing I have tweaked is the series notch filter. I increased the 12uF cap to 14.2uF which drives the first breakup node down to almost 30db and the 2nd down 40db. This changed the xover to 1950hz. The phase and group delay look a tad better also. The other one is the Audax 5.25 and MDT20. This is also a nice pair and not as revealing as the RS150. I took some measurements on the RS150 and they were solid down to 80hz and which point they start a gradual decline down to 40hz. The bass is outstanding on the RS150 and I would characterize it as leaner and meaner than the AR.Coms. These can be hung on a wall as they are sealed enclosures. Hung on the wall, the bass is extended.
