I bet these cabs would be a great basis for a Helix + power amp setup either with guitar or (of course) bass.
In other news, my cab building journey has finally begun - although in a slightly disjointed way. I had managed to buy some poplar ply from Mike Walsh (Zoot bass) - who has stopped building the Purple Chili cabs to allow him to focus on building basses. He had a sheet or so of poplar ply left over, and sold me the ply with the basic cuts done for me. I moved house this year and have now (finally) got a lovely shed (albeit without lights and power yet) - but other priorities keep getting in the way (redecorating, rebuilding etc) that for some inexplicable reason according to other members of the household (ahem) should take precedence.
Anyway, Mike has taken pity on me, and has offered to put the cabs together for me. I should stress that he is doing this as a favour to me - he is NOT going to make any of these cabs commercially, and doesn't have much left in the way of the poplar ply anyway. Stevie's flatpack kits are a much more sensible way to go!
Mike has some odds and ends of hardware left as well, so there may be a couple of cosmetic differences (connector plate, different feet etc), but the important stuff (port, drivers, wadding etc) will be to Stevie's spec. The ply is going to be 12mm in the main (as that is what he had left), though with the baffle done in 15mm. I'd originally intended to do it in 12mm but with a 12mm baltic birch baffle, but since there was a bit of 15mm poplar available, then that will be used. Of course this also means that the dimensions of the panels will need slight adjustments.
I had always intended to build a pair of cabs, but one is going to be without tweeter. Stevie has recommended that when used together, the tweeterless cab should have a low pass added at around 500Hz, so there is little or no interference between the two boxes. We'll see what happens there when we get further along the road.
