OK kids, hopefully this will be the last word on Guitar Amplifier Isolation Cabinets…
Chris Briley (again, one of the masters of the universe) passed along the following 4 PDF documents that help explain our Iso Boxes…
Our first generation boxes were about 48″ wide and about 33″ tall, and about 48″ deep. This seemed a reasonable height at the time, considering they would need to be stacked on top of one another due to backstage space restrictions.
However, as the Browns Bridge and Buckhead church buildings were being built with a larger backstage area, it allowed an opportunity to improve, and even simplify the design. So the newest generation cabinets are 48″ x 48″ x 48″. They’re just a big cube made from 3/4″ MDF building material. They even had the sheets of MDF cut at Home Depot.
There’s no official measurement guide to the boxes, other than the fact that the top and bottom are 4′ squares – so let’s do the math on the rest together, OK?
Top – 48″ x 48″
Bottom – 48″ x 48″
Sides (x2) – 48″ x 46.5″
Back – 46.5″ x 46.5″
Doors (x2) – 46.5″ x 23.25″
I think those measurements work. I’m sure you’ll want to double check the math…
Also, the new boxes, because of their height and because they’re not stacked on top of each other, don’t require a tray that rolls out. So that helps! There’ now lots of room to stick a big Marshall cab in there…
NOTE: Iso Panels 1 and 2 are simply reflect Box #1 and Box #2 (meaning guitarist #1’s amp and guitarist #2’s amp…)
These panels were custom made by Rapco . Chris just sent them the Iso Panel PDFs and they made each one for about $150.00.
**This panel replaces our “Generation 1” pop-up boxes that have ended up being a pain and we no longer use on newer boxes.
NOTE: Sends 1 and 2 are for mic level input (for use with Combo amps), Sends 3 & 4 are used for Speaker level inputs (when a head is used on stage and a speaker cabinet is in the iso box)
NOTE: The RJ45 (Ethernet) jack was installed and run to stage because of future uses. No one currently uses it, but theoretically it could be used with a Line 6 pedal board linked to an amp in the iso box via Ethernet cable…
NOTE: The acoustic treatment can be acoustic panelling (that you cut to measure) or acoustic treatment stuff, like this Auralex stuff.
So altogether, it looks like you can make each box for under $400…
And here are some pics of our “Generation 1” boxes for inspiration:
