Been a while, so it's a good time to update this thread...
As you will have seen, I started off by building a very small compact subwoofer unit...and more recently replaced it with a larger unit, containing a 15" drive unit that I made a few years ago

It was great, but a little too large, and left me too little boot space for holidays with the kids' suitcases and toys

So, I decided to make something in between

I opted for a single drive unit, as I wanted to make the box as small as possible whilst maintaining the correct volume to match the thiele small parameters, and therefore get the best out of the drive unit. I chose an Infinity 12" unit, as the price and spec were more than suitable for my needs

Then it was a case of making the box...
I used 18mm MDF - nice and solid and weighty - and made a start on my 2 box system...
You can see that there will be 2 boxes, one for the drive unit, and one for the electronics - I decided to do something a little different this time

Top and back in position, with a matrix brace to assist in moving the resonant frequency of the rear panel out of the range it will be subjected to

Rear panel starting to take shape

Front cut and fitted

Shaped to fit the boot plastics

I needed to allow the air to circulate in the other box, so I cut in a recess
[img]http://i168.photobucket.com/albums/u177/marcrs323/323/sub%20v3/230520112603.jpg[/img]
then covered the hole with a false panel - this will line up with the split in the rear seat, and hide the hole

The other side needed a cut out
[img]http://i168.photobucket.com/albums/u177/marcrs323/323/sub%20v3/240520112609.jpg[/img]
to allow for the cables

test fit...

Time to paint some black

[img]http://i168.photobucket.com/albums/u177/marcrs323/323/sub%20v3/240520112612.jpg[/img]
and some red

[img]http://i168.photobucket.com/albums/u177/marcrs323/323/sub%20v3/250520112620.jpg[/img]
Then time to cover in heavy duty cloth
[img]http://i168.photobucket.com/albums/u177/marcrs323/323/sub%20v3/250520112624.jpg[/img]
but leave the rear panel for now
[img]http://i168.photobucket.com/albums/u177/marcrs323/323/sub%20v3/250520112625.jpg[/img]
Then it was time to add the finishing touch...some work on a panel for the rear...
[img]http://i168.photobucket.com/albums/u177/marcrs323/323/sub%20v3/280520112637.jpg[/img]
Yep, lots of cut-outs, ready for some foam...

And here it is...sub v3

more room

[img]http://i168.photobucket.com/albums/u177/marcrs323/323/sub%20v3/DSCF5876.jpg[/img]
You can see it slightly lit here...
[img]http://i168.photobucket.com/albums/u177/marcrs323/323/sub%20v3/DSCF5869.jpg[/img]
there are 96 LEDs illuminating the amp, 48 white for light, and 48 red to show the colour

[img]http://i168.photobucket.com/albums/u177/marcrs323/323/sub%20v3/DSCF5867.jpg[/img]
and the rear...

[img]http://i168.photobucket.com/albums/u177/marcrs323/323/sub%20v3/DSCF5779.jpg[/img]
the split is lined up with the seats

[img]http://i168.photobucket.com/albums/u177/marcrs323/323/sub%20v3/DSCF5872.jpg[/img]
the rear panel holds enough kit for a bit of a freshen up - detailer in the large bottle, wheel cleaner, tyre dressing, microfibre spray, paint cleaner, and wax...

No pics of the cloths, but they're on the other side of the box, tucked away
