These Incriminator Audio Judge drivers have a custom suspension and had additional mass added (3 dust caps) to lower the Fs from the stock 34hz to 26hz.
The eight drivers are going in large dual-opposed boxes that are 24” wide, 22.5” tall, and 55” long (3" thick baffles). That’s roughly 13.4cu.ft before drivers and bracing. Stuffed in each cabinet is 6 pillows.
I used 3/4” MDF and quadrupled the baffles. Securing the drivers to the cabinets are 1.75” stainless steel #10 wood screws. I could have used bracing that would consume less internal volume, but for this build I chose a simpler/faster approach.
The two drivers in each cabinet are each DVC (1.5ohm per coil) with the coils wired in series and then the two drivers are paralleled, and then two cabinets are wired together in a series. For the amplification the current plan is a pair of bridged Crest CC5500, which may change later to a couple SP2-12000 or K20s.
Posted later will be frequency response sweeps and SpecLab captures.
