Mini Rigs of Doom Four

I'd love to hear more about that cab...

I’ve always wanted to try an isobaric cab build, so when somebody gave me an old Hartke transporter 4x10 cab with two blown speakers, I figured why not.
Hartke doesn’t publish the T/S parameters for their drivers, so I just used the Hartke cab measurements to figure out the enclosure port tuning and internal volume. Using 1/4 volume requirements for each driver, then half of that for the isobaric internal enclosure, I came up with a design that I could just fit into a roughly 13” cube enclosure. I used a single angled corner port into the back enclosure.
As it turned out though, the original speakers rattled when given more then 50W so I swapped them with a pair of Faital Pro 10FE200 drivers. At only $65 each and with the math showing them behaving in the box, it was an upgrade.
Overall, the final build has great low end and top end clarity with a bit of a mid scoop, which is perfect because I plan on mainly using it with an electric upright.

Here’s a time lapse of the final assembly where you can see the inside of it:

Have any sound samples? I'm curious about these PJB cabs

i didn't. i found an app, recorded it, it sounded okay but saved as an MP4a, which couldn't be attached here, so i used a free converter, but it made it sound less bassy. sorry i could do better.

btw, in real life it doesn't sound like a small speaker at all. i've had a couple disappointments - this cab is nothing like the blackstar fly 3.

Is this an MROD, or a Janky-Ass Rig, or a Mini-Maxi rig? Or what? IDK. I had a rehearsal in someone's basement and this was the rig: a teeny tiny TC Electronics BAM 200 on top of a massive vintage Kustom 3x15 cabinet. Like a Chihuahua riding on a Saint Bernard. If you weren't paying attention, you might not even see the amp. Sounded pretty good!
