I have some questions regarding the differences between a center speaker built as WTMW and possibly WTMMW as pictured in post #59 on page 3 of this thread. In post #60 it is stated: So, I have a few questions about this. First, could the circuits from the WTMW center and the MTMWW right/left crossovers be mixed for a WTMMW center? As in, could the LF (and possibly HF) from the WTMW and/or the MF & HF from the MTMWW be used to at least overcome the suspected lump in the woofer response, or would this just cause other problems? Would the benefits of a second midrange speaker be worth the drawbacks of the different positions of the MF/HF speakers, with or without mixing the crossover circuits? Lastly, can the box be built with greater length and shallower depth? Due to space considerations, I would like to keep the speakers tightly spaced in the center of the box, without changing the inner M/T box size, while extending the length of the front baffle, cutting down the depth of the box, and possibly using some angles on right and left ends of the back of the box. Assuming the internal volumes don't change much would there be any reasons why I shouldn't do this? Thank you very much for your time, not only with these questions but also with the designs themselves. I am just starting my journey into this hobbly and your efforts are greatly appreciated.
