It is possible however typical postage (secured, 10kg) is about 200 USD. Maybe try Azura horns made in Australia?

What is that in the large horn of the rockets? A large cone/ compression coax driver?

Interesting show of versatility of your mid horn. What frequency are the crossovers.

For those who like BMS 4590 here is crossover I made for a friend that uses Altec 416 (Onken 380 liters) and Minphase. It is based on full 180deg polar.
