This is going into a modular system that will go to festivals. We're already looking at a booking for Burning man this summer into a PsiTrance camp that may use it all.
There will be 3 "subsystems" that can work individually , or together. Each subsystem consists of 4 MWM's, 2 MWMS, 2 MSSM, and 2 MSM, and potentially another tweeter depending on the driver we select for the MSM. Each "System" can operate as a stereo pair, or be operated as a Mono component to a larger system., so, 2 systems could be set up as left and right channel, and the 3rd o our 3 systems could be a stereo pair split between house left, and right, or perhaps a center channel, or any number of supplementary configurations, or as a "second stage" for festivals that need such configurations.
With new drivers in at least the MWM's these systems can hold their own against Funktion One party stacks which have become a benchmark in the electronic music festival space.
The amplifiers we are using are older Crown K-series "Balanced Power" amplifiers.. A single K2 amp is used for each MWM, and a pair of K1 amps to drive the MSM and MSSM cabinets. Each "subsystem" can produce 130 dBC below 80 Hz, at around 120 dBA at 20 feet, while consuming a fairly steady 16-18 Amps. This means each system only requires a single 120 VAC outlet, and we've even done 130 dBC on a really clean signal source and kept it under 12A at that show. When doing mobile sound at festivals in remote locations, AC power budget is a matter of critical concern, so this efficiency is remarkable.
We currently have enough amps and cabinets to operate 3 "systems" as described. We'd like to find cabinets, and parts to build a 4th.
