Roughed out with jigsaw, then spindle sanded to the correct diameter. This just shows what gear is needed to do a good job - it makes the flatpacks a no brainer!!! 2 Quote Link to comment Share on other sites More sharing options...
stevie Posted November 21, 2019 Share Posted November 21, 2019 I happen to have a hole saw that cuts a perfect hole for the port. However, I built the first prototype cabs from panels cut at the wood merchant's and I know how long it took to assemble them - bl**dy ages. The flatpacks make it so easy. 1 Quote Link to comment Share on other sites More sharing options...
RichardH Posted November 21, 2019 Share Posted November 21, 2019 One thing that may or may not be worth taking off to a separate thread until sorted. The "sub" cab will need to be set upside down so the two 12" drivers are as close as possible. This makes the handle positioning a bit interesting. I had thought to just build the cab as designed with the handle on top, but add feet to that top surface so it could be plonked down upside down. A bit of a bodge maybe, but I wasn't sure if having a handle impinging on the wadding down by the 12" driver was a bad idea, so thought it best to keep things as standard...

If you just flip the baffle upside down (and back to front) does the handle get in the way of it? 1 Quote Link to comment Share on other sites More sharing options...

Rough cut for the baffle holes Making the port hole the right size... ...yup, it fits One baffle done... ...which is then used as the template for finishing the second. ...and there we go I am still intending to run the second one without tweeter, but since I have two horns I thought I might as well have the baffle cut for them, and then seal the horn instead of fitting the compression driver. If I then want to run them as separate cabs or for keys or something, it will "simply" be a matter of another driver and crossover. I bought the horns ages ago (as well as the two drivers) - I suspect if I'd held fire and read the comments from people who have them up and running, I might have just gone for one cab, but hey ho! There’s the new hifi speakers sorted! No more packing your gig stuff away during the week. 1 Quote Link to comment Share on other sites More sharing options...

I would expect there to sufficient clearance (but I haven't checked specifically and will do later). It should just be a matter of swapping the top and bottom panels.

RichardH Posted November 22, 2019 Share Posted November 22, 2019 I'm sure there will be clearance, I wasn't sure if it would have an effect on the wadding. Sounds like that shouldn't be an issue though - thanks for the reassurance! Quote Link to comment Share on other sites More sharing options...

It should just be a matter of swapping the top and bottom panels. Don't worry Stevie, we can check ourselves. So long as there's no design issues with having the handle at the bottom then we can give it a go. Obviously the relevant damping will be fitted to the panels which ever way they go up.

Pea Turgh Posted November 22, 2019 Share Posted November 22, 2019 Looks ace, but I’d address the fabric ripples. Maybe try removing the grill and putting a hot hair dryer to it? Failing that pull the staples out and start again. Sorry for the negativity- it really is an ace looking cab! Quote Link to comment Share on other sites More sharing options...

Hot hair drier works if it is a plastic based "cloth" - not sure what that stuff's made of, so safest to test on an offcut first! And be warned... although a hot air gun can also be used, be very careful not to get too close with it - don't ask me how I know.... Quote Link to comment Share on other sites More sharing options...
RichardH Posted November 22, 2019 Share Posted November 22, 2019 A bit more progress on the evil twins... Cutting the ports to length - overkill with the saw? Nah..... We're using some odd bits of hardware that Mike still had left over, so these will have a rectangular handle ...and a metal connector dish 2 Quote Link to comment Share on other sites More sharing options...

Not overkill. I tried using a chop saw at first and it splintered. In the end, I used a handsaw, but your solution is much better. Quote Link to comment Share on other sites More sharing options...

I've mentioned it before I'm sure, but I've found a blunt handsaw (panel saw) to be much better at cutting drainpipe etc than a lovely sharp one. So for those without bandsaws, that's the way to go!

Doesn't all the spare sound drop to the bottom anyway, so the wadding at that end will catch it? 1 Quote Link to comment Share on other sites More sharing options...

True, the spare sound drops to the bottom, but that’s why most lightweight cabs have ports there - to let all the heavy notes out. That’s why port size is so critical - if you let too much sound out, the cab simply floats away. At least, that’s my understanding of it all. 2 Quote Link to comment Share on other sites More sharing options...
