Next step is to make it run on 18650 Li-Ion rechargeable cells. Obvs.
I just bought a TC Thrust, so I totally get the trash thing. Love it.
I haven't seen anyone else ask yet, so I have to ask: how long can it run on the 8x D cells? Really neat idea!
IMHO that cab covering is way better than rat fur...
Makes me wonder what can be done with a milk crate and some way to cover it.
That's a cool idea!
Just a fun $50 project. OP obviously knows he's not approaching the durability of Baltic birch.
Does it have a boxy sound?
I know that - I was postulating the limits of this construction technique, which may or may not be able to be sufficiently tough with enough layers and technique development.
Obviously, the OP's box is a simple home project, but I develop products (and processes to make them) for a living, so I do a lot of postulating about where things might go. I have a bass where the tuner holes were bigger than I wanted them, so I reduced the hole size with....grocery bags and glue as a composite - that technique, as home spun as it seems, is much tougher than the wood around it.
A spherical enclosure is a very good idea (aside from the tendency to roll around) - when you pressurize it with sound waves, the entire surface is in tension - it's ridiculously stiff. A balloon as a form for a composite spherical structure would be one way of making a light, stiff enclosure. If you've ever seen woven composite pressure tanks, they're either spherical or cylinders with half spheres on each end for this very reason.
Well yes, but you're aware of the fact that he's already built the thing right?
What should we call this new composite?
I know there's basswood.
I know there's boxwood.
Would that I could know what wood it would be, if it would have wood in it!
Well, just add some tort and it'll be fine.
recycled toilet paper wood
Yes - the pictures pretty much solidified that. Given that his is already built his, the point of the thread is not advice.
Extrapolated Cord wood cabinet. Love it, McGiver Cord wood bass cabs.
I thought about branding a line of cardboard cabinets marketed towards the cost sensitive consumer. The company would be called Bargaintino Audio Systems and the logo would be written in lime green on a piece of black duct tape. Do you think Jim would be OK with that ? Only a few of you big dog high end amplifier and cabinet snobs will get this one .
Oh, and I would spray paint the cardboard cabinets black and maybe tape on a piece of black screen door screen over the speaker to make them look more like a real cabinet. What do you think ?
I assume many have seen the building of a cardboard Fender Strat. (Check YouTube)(Fender factory IIRC) There was nothing lacking tone wise in it. Wood neck, though, and body of cardboard reinforced with resin. So, What would be a cost effective resin to coat the surfaces of this cab with? It would increase strength and rigidityand improve tone, but of course, at a cost.
That is a good question, Kirk. What immediately came to mind is to spray the exterior cab surfaces with something like superglue, so it would have a sort of shell
like an insect. Cyanoacrylate might be too expensive, but maybe not if you bought it by the 55 gallon drum. It might not be strong and rigid enough in a thin layer, either.
For an extremely durable and inexpensive outer covering, look up poor mans fiberglass. Two things are needed...canvas drop cloth and wood glue.
