Ok first of all ive never designed anything before but whilst at work had this thought which had to put down on paper. Idea being using 4 x 10" or possible 12" drivers. Baffles would be angled in to match back of the bung either parallel to or slightly off parallel. Have constant expansion with minimal flat panels or angles, all smooth contours. Box would be 626 sq though depth would be more. Aiming for the upper bass / kick range
I name it the lemon bin Obviously some nasty compound angles on the baffles n the central piece would be lot of work but. i have acess to large cnc mills n lathes so won't be as hard as trying to do at home. Thoughts? Ps. excuse the poor drawing skills Edited by Twiggy - 15 June 2013 at 1:49am |

elaborate idea and very cool! you'll need to draw it out to scale. start with paper cut outs of the driver/s and draw box onto grid graph paper. there's a feeling it may end needing to be bigger. atm the drivers in the drawing could be no bigger than 8" if you looked at it to scale. nice work though, aint it hard to stop thinking about speakerplans when you're at work

It Is hard, foreman always giving me grief for being on my phone on sp
Well obviously atm is just a crude fag packet sketch atm. I will scale it properly and start working some proper preliminary dimensions. Hardest part I see is working out the baffle arrangement, whether each drivers throat and rear chambers are shared or isolated, I think rear chambers will be seperate but not sure on throats? You are right, does look like 8's. As said very early stage drawing, could move baffle structure further forward though making drivers closer to 'the lemon' and giving more room at back corners for the drivers. |

There are some pretty robust 8 inchers out there these days. You may be able to do pretty well with the right ones.

try the rcf MB8G200. I modelled some horn loaded kick bins with these but never got round to building the prototype. Still got a pair hanging about if you wanted to take them off me.
cheers Phil

@ Twiggy: You can made such Bins significantly easier ... take a lock on the "Void Incubus" Mid-Bins. |

The incubus hyperfold is a larger box (738x738x1218) and uses 4 x 15" drivers. No idea what's going on internally though.

Certainly not 300L of wasted space and 150kg of added weight in the form of an overgrown lemon I'll get my coat... |

The lemon centre bung will be adding a lot of weight, but aiming to keep that down as much as possible. Thinking I would cut rings of wood in increasing sizes and sandwich these altogether leaving the majority of the centre hollow apart from supporting braces. Could find other uses for this free space, some sort of led effects maybe? Getting ahead of myself
