Here's a 2 X 15" folded bass-bin cabinet, Ideal for club and party systems.... Use this with Mid-High cabs.
Ok... Not so simple this one, but... This is a 'Short-Throw' bass-cab, and thus ideal for a club/party sound, where you want good radiating bass... There are other designs, such as W-bins, but they are generaly Long-Throw.
You'd better be good with a saw, and get yourself a mitre-form cos you need to cut alot of mitred joints, and they need to be accurate.... Still, for a few bucks/squids, the wood-shop should assist you if you present them with the plan.
At first the plan does look a bit hair-raising, but start to visually strip it down, and it gets clearer.... The best way to do it, is to cut out the side panels, then do all the measurements on the inside edge of the two sides, and mark it out with pencil.
Next, get all the inner panels, and sit them on the drawn out lines/plan.
Do plenty of dry runs, (putting in the center pieces, then lowering the other side panel onto the top, without glue or screws to check all the joints).....Again, the mitre-ing (cutting of angled joints) needs to be spot-on... You can't have loads of gaps everywhere.
You'll see 2 small pieces labelled - "Bracing Stuts on CL" on the plans.... these are to re-inforce the first two angled inner-panels at their center point ......these struts should be right on the center-line, made from planed baton...The two final inner-panels holding the speaker units are naturally re-inforced at the center by their connection at the angle of convergence (er... where the ends meet).
All the inner, top, front and rear panels are of course, the width of the inner-cabinet width dimension....basically, everything is contained within the two side panels..... It seems a bit weird, but once the sides are screwed into these pieces, it will all come together.
This cab has a removable back panel so you can get at the speaker units... it's a little unclear from the plan, but, the inner-lip runs all the way round the opening.... The final back-panel fits in flush with the back of the cab...
DO NOT use chipboard for this cab... use PLY or MDF.
You can build another pair, and add them together with the first pair for more power.... If you do this, you get an even lower bass response, down to 38Hz... just make sure of the impedences, and the way you wire it.
The speaker brand is up to you. Check with the supplier for cross-over if used in a passive system..... It should be rated at 500Hz.
