This is my ported enclosure I built for the Adire Brahma MKII. It's 2.0ft^3 tuned to 28Hz.
The beginning of construction
Up close of my 28Hz tuned slot port.
The DVC terminal cup wired in parallel to produce a 4ohm system load. I can easily make a 1ohm system load by simply re-wiring at the terminal cup. It's a lot easier than removing the sub.
Testing/Break-in being powered by a QSC USA1300 professional power amp.
Excursion pic during testing/break-in. Will post bigger and better excursion pics after it's broken-in.
I incorporated a grill design used in sound reinforcement enclosures. I lost a sub due to no grill protection. Can't let this happen to my Brahma!!! The grill design allows 2" of excursion without any interference.

Overall, I'm extremely satisfied with the results. The sound is absolutely amazing. Hits extremely low and clean, very transperant. Right now I have it my apartment since I'm wating to get the a new amp for the car. I believe my neighbors hate me now since it's so loud. Anyways, I have yet to finish the exterior. Still have to decide on what to cover the enclousre with. I'm going to router the edges and then maybe apply Dupli-Color truckbed liner. Not quite sure about the truckbed liner since I've read some negative results about it.
For those of you who like the box. I'm willing to build it for a reasonable price. I would say around $110ish. If interested send me a message. BTW, I'm not trying to steal business from other builders on the forum. Just trying to led a helping hand.
