Enclosure for DD2512a
 
Hi

I will have to build enclosure for Digital Designs 2512a. I will try to build one from DD site. As they say sub takes about 6L of space. Box would be made from 19mm(0.75in) MDF. I would go for 50cm x 50cm for top and bottom side, this will be base for everything else(green ones on page). Left and right sides(yellow) would be 50cm x 32cm. Back side 46.2cm x 32cm. Front(red) 39cm x 32cm, with hole= 29cm, 5cm from each side of the board.

Port(red) is 32cm x 32cm, which makes 7.2cm x 39cm x 32cm high port.

Is that ok?

I ask this because box should have about 60L or 2.25^ft, but I calculated only 47L, without port...Should I add port volume as part of box volume that sub uses? If I do that I get to 56L, that is ok, right?

Should I change anything or... comments are most wellcome

Hi

There are 33 of 35 screws on top, 2 are not there because there were too long. There are another 35 from bottom + 4x 5 that hold each side together, so that is 88 of 90 screws total :D

That you want? To send you original pics?

You should be able to see all of them :confused: ...

Hi

Loooool don't tell me that you like it so much?? I didn't even finnished it yet, should at the end look like it was/should be part of trunk that it is in :D. But thank you very much... I have to say it came out pretty good if I tell you that I did only hand drawing from top (1/10 scale) to get size of sides, so I could buy them, everything else was done pretty much as it was build, about 5-8 working hours later this came out... I just wanted to build it as fast as possible, to hear the sound of speaker... First test, about 30s from when I started car, turned on headunit and selected some song from USB, sound came out and I was left :bigeyes:. All other speakers before that I heared were nothing compared to this.
