Thanks, I’ve replied you by email – you sent me by mistake 15” version and I was interested more in seven π-18 corner horn “Premium Series”.
As I already have 4 pieces of kilomax 18” I was wondering to use two of them per side in push-pull configuration in order to decrease volume of the box and also to decrease distortion (kind of shorting ring effect?).
I suppose in this case I have to reduce cabinet volume by 2, to recalculate the port length accordingly and, the hard part, to recalculate crossover in some way – could you help me with that please?

Thanks,

O’Tor
