I acquired an Angstrom Center Channel speaker model: Modular Six/C. Instead of what's normally configured as an MTM with tweeter in middle for a center channel, it has one 5" Vifa glass fiber mid/woofer (SG14SG01-8 ohm) with two Vifa soft dome tweeters (TC20SD05-06) on either side in a vented enclosure. It sounds good but was seeking some comments on this TMT layout compared to MTM. Granted an MTM speaker lying down is not the same as an MTM standing up (a.k.a. D'Appolito) and the polar sound distribution (hence lobbing effects) are not ideal in a horizontal position compared to vertical. I understand what the best layout for a center channel is W-M/T-W and that is woofer on the sides of a tweeter above a midrange in the middle. Anyone see the benefits of this TMT config. and if its better or worse than an MTM type as far a phase/lobbing and ultimate speech articulation, etc.? I struggle to see anyone using this layout in a center channel speaker or otherwise...
The www.dulcet.com address didn't work...? Not sure if I can help on all the center channel possibilities you mentioned but its worth detailing what they all mean i.e: example what's an MTMTM, TTM etc. (how are the drivers aligned)? There are numerous possibilities for driver layout and unfortunately the space below (or even above) a TV panel has limited for speaker orientation, hence a horizontal MTM is so popular but not the best for fantastic articulation.
