Sorry to bump this thread, Rick, but can you comment some more on the sound quality of this speaker? I'm especially interested in the MTM with a 4" midrange and a ribbon tweeter. My initial thought would be that this could be an amazing combination, but I know there are some crossover/vertical dispersion reasons why you prefer using a dome tweeter with 5" drivers and a low crossover point in the RC5. Any feedback is appreciated, and thanks again for your active participation in this forum.
