I originally posted this in the NatP thread since those speakers are being considered. I deleted that post & moved it here, made it more general in hopes of getting more discussion.
Soon I'll start a thread with more detail of an upcoming family project, but to summarize: fairly large (mainly deep) room with a large opening in the back, 100" screen and speakers either on the wall or built flush into the wall. Still definitely in planning stages. After reading through the entire thread, I have a couple of questions.
--I read that on-wall mounting, with a deep enough cabinet, the given crossiver & incorporate BSC are probably acceptable for most of the speakers in the Missions Accomplished. Are there any easy changes (i.e., varying a resistor, bumping up woofer section's inductor gauges, larger gauges in the tweet circuit) in the crossover that would easily knock down the BSC enough for flush mounting?
--The size of the screen may dictate that the center channel's highest point is only ~4 feet above the floor. This makes me think a horizontal placement should be considered, since it puts the tweeter nearer ear-level. With the given size screen, most listeners would be at least 10 feet from the screen. Would this distance create a listening window wide enough to overcome the usual negatives that come with a horizontal MTM center?
--Would a sealed version of a speaker raise impedance in the lower octaves much? Mainly this concerns surrounds, which will likely be crossed over at 70 or 80 hz anyway, but since it will be a receiver powering them, saving the AVR some 'work' from pushing lower impedances may be nice. The front 3 would definitely be ported
--Also concerning being powered by a receiver, could one build these as bi-ampable? Assuming the given receiver has a setting where the surround back channels can be used as additional front power. Some do have this feature, IIRC, right? The decision has yet to be made on 5.1/2 or 7.1/2. The surround backs would most likely be very far back Modula MTs, if those rear channels are used. Again...the audio is in the planning stages.
