Customers can purchase either a two or four channel system, with optional subwoofers and as many amps as required. The entire crossover function for the drivers is done digitally in the same box with the amps. Systems range from $30-40k depending on how many channels and subs and should be available sometime this spring. Even in a small room, the demo was most impressive as we ran through our "torture CD" demo tracks. As Wes Phillips commented as we left, "I think we've just been given a glimpse into the future."
