OTL/Line Array thought problem

OTL Asylum

OTL, Output Transformerless Amplifier User Group.

I want to build some line array speakers to use with the T16. The thing with line arrays is that in order to compensate for the differences in distance from each speaker to the ear they are often wired in a manner called power tapering that makes the center drivers louder than the ends. For example, with an array of 32 2" 8 ohm drivers the center four are a serial chain (32 ohms). This is surrounded by two serial chains of six drivers (48 ohms each), and this is surrounded by two serial chains of eight drivers (64 ohms each). When all the chains are wired torether in parallel you get a tasty 9.6 ohm system where the center drivers are louder than the ends due to lower impedance.
The question is, how would this work with an OTL amplifier that is louder with higher impedance systems? Would the center drivers still be louder than the ends or vice versa?
