Hey all. I’ve been banned for life from The legacy AVS Forum for creating a new user profile when I was victim of a hack in a very sensitive career profession and was told to create all new user accounts for everything. So, I’m bringing my build to tell the story here! This project began over a year ago and was put on hold for the summer. I’m finally ready to load the cabs and begin testing, what I like to call the 412MBT (mid Bass Tower).
This is a design using the Custom Eminence Magnum 12 designed my Matt Grant and Erich from DIYSG. It’s one of the most amazing drivers I’ve come across. There are 4 of these in each cab ported and tuned for 42Hz! 500 Watts per driver brings each to XMax by design and port velocity of 19m/s. Sensitivity at 1.4v/1 m is 106db for the 12s at 2 ohm total load.
The BMS is behind a 18Sounds XT1464 15x12 Horn. It’s an amazing combination. It will be crossed from 350-450 Hz depending on what I get for distortion below 500hz because of the older 4594 design (new HE doesn’t have this issue with a new phase plug and increased driver diaphragm distances).
The box will be an active DSP processed unit using a Driverack Venue 360 initially and perhaps moving to MiniDSP 2x4 HD later.
Pics coming next...
