Outside of the already constructed bass towers, is there a reason you are looking exclusively for 10" drivers?  I have heard a pair of stacked 15" Lambda's on each side supplementing/providing bass to lower midbass under some Oris horns and it worked quite well.  15" drivers will have their own benefits and drawbacks; I am not yet in a position to identify this, but on paper, they will be able to go as high as needed, can be picked up with larger magnets and tend to have a bit more sensitivity.  Is there something you find interesting about the just 10" for bass?

Certainly there are no other reasons then to use the existing bass towers. If I had space then I would probobly go the line arrays with 15” and if they were good drivers (as hard to find good 15” as to find good 10”) then the 15” would produce superior result. It is important do not use the 12” drivers – they never ever were made good quality but the 15” are fine, the 18” even better, thanks God there was some very good 18” produced. Still there are a few “issues” for the line arrays of big drivers. With even 2 X18” of the quality that I mean you would need 20-30 cu feet… that is kind of large…. Also, all of them need a lot of power to drive them, so they certainly are no SET friendly, not to mention that practically all of them do very bad at upper bass. The 15” are very good compromise, they might be fairly SET-friendly and can handle the upperbass’ first order. The entire idea of my LF section was to make the small line arrays with minimum footprint that would perform at the level of 15” array, or prefabs better. The idea pretty much grows around the 25W/8565-00 capacities.  You might have some difficulties to find a 15” driver that would be able to perform at the 25W/8565-00 level. I know some 15” drivers that do better at upper bass but they all have air resonance at 40-50Hz. I do not know any 15” with resonance at 20Hz that sound good all around, although I did not dig very deep into the 15-inchers

BTW, thins to anyone who suggested different drivers, I have decided to do increasing the number of the 25W/8565-00 section….
