I have the RM40s and don't find the Coincident T.V.s compare.
Please consider I am biased:
1) I have RM40s in my personal system
2) I am a VMPS dealer (as well as over 20 other speaker brands)
But I have heard both and might offer the following:
Placement: The CTVs with their sidefiring woofs are much placement sensitive and suffer greatly if placed on the "long wall" which always offers the best imaging and soundstage.
Sound: The CTV is at least a 4 way speaker meaning at least 3 crossovers or blends. The Neopanel Ribbon of the RM40 covers the spectrum from 166Hz to 10Hhz. This presents an incredible cohesive sonic purity to this all important range.
Price: CTV = $11,500 VMPS RM40 = $4600
Looks like an easy decision to me, Actually it was : )
Just my admittedly "biased" thoughts.
