With all of the knowledge about CC speakers that I gained over at AVS, I was reluctant to go with the MTM design, because it is in fact is a compromise.
I was fortunate to have 2 vintage Sony CCs that I was able to experiment with in my room by checking (aurally) for off-axis response & sound degradation (comb filtering), etc; however, I found that there were no significant detrimental effects with this design in my room. Therefore, when this VP100 came up on auction at such a good price in a compatible colour, I jumped on it.
While the nasty effects of certain horizontal CC speaker designs are real & measureable, I believe that in most setups in the real world that these effects are often minimal & go unnoticed by most people.
It's not as big a deal as is often made out to be IMHO...
