This has probably been beat to death, but I'm curious about it. Let's use a single VC 8 ohm woofer, and say it's 90db sens. Can someone let me know if this is correct math?...

2 woofers, each a single 4 ohm VC, 90db sens, wired in parallel= 2 ohms, +3db, so 93db sens.

2 woofers, each a single 4 ohm VC, 90db sens, wired in series= 8 ohms, +0db, so

If that math is correct, what is the gain from using (2) 4 ohm woofers in a MTM/TMM wired in series; verses just making it a TM? I could definitely see if these were 8 ohm woofers- the gain from wiring in parallel would be +3db sens; but using 4 ohm woofers wired in series in a MTM, what's the gain in going to a MTM vs just making a TM? The sensitivity is the same for both.

I can make some assumptions but not sure if they're true... For example, I would assume you would have better power handling and more output from the 8 ohm MTM, verses a 4 ohm TM; the MTM would play cleaner at higher volume... is this correct? Any other pros/cons to making a 8 ohm MTM, verses making a 4 ohm TM using the same woofer?

**it remains 90 db sens**; correct?If that math is correct, what is the gain from using (2) 4 ohm woofers in a MTM/TMM wired in series; verses just making it a TM?
