Default Isobaric questions.

I'm looking at an isobaric multiway for my next project. Reasons for considering - the bass drivers (satori 9.5") are available in asia/arent crazy expensive, but they need a large box. They also look great flipped.

There is a choice of 8ohm 88db or 4ohm 91db. I'd like to use 2 pairs per side as in the sketches, and this shows 2 ideas. For system sensitivity and output, which wd be the best option? Also, what wd be the limit of crossover point (to midbass)?

They'll both work the same, give or take. I'd use the left one up to around 200Hz, and the right you might get 400Hz. The left one gives you vibration cancellation, at the expense of the cabinet needing more space behind it.

If you went 3.5-way and moved the woofers up, you could probably use the left one with a 400Hz crossover point, too.

Thanks Chris. wd it be better to parallel series the 4ohm version? Not sure what figure I'd end up with inc floor support
