Dad3353 Posted August 12, 2021 Author Share Posted August 12, 2021 (edited) Bass cabs, and amps, we have in plenty. They do a fine job, for small, pub gigs, festival stages and rehearsals at home. However, a new genre has turned up : garden party, or living room, jams or micro-concerts. The essence of these will be almost spontaneous, light-weight affairs, with minimal gear (but of good quality...). There's the rub, presently: we have a practise combo, but it's a bit past its sell-by date, and puny, even then. A recent garden event showed up its weaknesses. It doesn't 'cut the mustard', and for these events, we don't want the faff of a Big Rig (in this context, a 4x10 Ampeg is a Big Rig...). That's the issue; here's the solution... A while ago now, I bought, from a fellow BC member (thanks again, PPP...) a set of six Phil Jones five-inch speakers (OK, 'drivers', but I'm old, you see, so they're 'speakers' to me...). Now is the time to see what can be made from them. Daft as I am, I immediately thought of the Phil Jones C2-type of cab, and decided to see if I could 'copy' the concept, and make a combo of it. We have on hand an amp (Hartke HA3500; overkill, really, but we have it, so...), so I sketched out a few ideas, and popped them into Blender (a graphics tool I use for 3D printing, making virtual model trains and other stuff...). Here's the result, modelled into 'real-world' panels and carefully assembled to check the measurements... If you've read carefully, you'll remember I had bought six speakers. Let's see what a modular system could look like, with a 4 x 5 extension cab... More modelling; this is what comes up ... All very well, but what will it look like really..? I don't know; let's find out. Here they are, stacked in a virtual salon, with a bonhomme for scale... Well, that's the idea, anyway. I spent two sleepless nights working out a cutting list from one single 2500 x 1220 x 12 sheet of ply, took it to the wood folk and had those panels cut. I've a few lengths of 17² for gluing into the corners; we'll see how it all pans out. It won't be quick (a couple of weeks, maybe..? We'll see...), but I think I have all we need to get started, anyway. To be continued; wish us luck ...

Cato Posted August 12, 2021 Share Posted August 12, 2021 I can't escape the feeling that the combo is staring at me. It'll be an awesome little rig but probably not particularly lightweight, unless your Hartke 3500 weighs considerably less than my early 90s model.

The combo has a shelf for the amp, and the 4x5 will really be 2 x 2x5, as there'll be a dividing horizontal partition between the volumes. I doubt that it'll get so loud as to resonate the panels, but we can always add later, if need be. It's an experiment; there's little 'science' behind it except having seen photos of the PJ C2. The rest (port volume etc... ) is just guesswork. 2 Quote Link to comment Share on other sites More sharing options...

At best, it'll get a rub-over with a sanding belt and a coat or two of boat varnish. If that's not good enough, I'm a fan of Hammerite. 1 Quote Link to comment Share on other sites More sharing options...

Our 'normal' rig is a Hiwatt 200w valve PA head, and an HH 2 x 15 folded horn cab. Compared to that, this is feather-weight..! No, the idea was not to get a 'one-hand lift' (possible, certainly, but would imply other investments that are not justified by the usage anticipated...). As long as it's easily transportable and set up, with no 'faff', that'll do. We play 'plug'n'play', so just plug in the lead and that's it. No pedal-board, DI out, monitoring or other stuff. Simple, stout, low budget. The wood, cut, with the 17², cost 90€ all in. I have the speakers and the amp, so...
