Please do. Do you know what the enclosure specs are? That may help me give you some info too.

before i post thoes pics, I got the wires and capacitor for free from a friend at vision audio. I cant return, but i figured i could use them? right?

free = good

keep the wires and sell the cap, search for the "big 3"

also, what guage wire is it?

Ok real quick: the middle sub slot is the only one i've cut to 15" so far. (thats why they look smaller) - im cutting the other two up to 15" this week.

Enclosure definitely looks excellent, and I love that concept. But, what is the airspace in that box?

Most 15"s call for 3-4 cubes, and that doesn't look like 9-12 cubes at all.

the box definately looks nice... I am really interested in the actual specs of the box to help recommend a nice sub

Thanks, I'm glad you like my design! It took like 2 weeks to build haha.

and i got the specs:

61" LENGTH

19" HIGHT

23" HIGHT (SLANT)

7.5" WIDTH (TOP)

21.5" WIDTH (BOTTOM)

24" PORT LENGTH

4.5" PORT HIGHT

Cap is going to be worthless. Don't use it. They tend to put a strain on an electrical system.

What is your goal with adding subs?

If you are willing to rethink a triple JBL 15" setup and switch to a strong single 15" or 18" sub setup, check out the DVC1 Fi Q and a KAC-X1R amp. Save you a ton of money and the 27mm of Xmax is nothing to scoff at. That amp will do rated or better power, according to the reviews out there.

Might have to throw another front baffle on the front and recut the openings to accomidate the subs. 3 cheap 15's might not be your answer. also port area might be a factor. whats the tuning freq?

ok i got the specs:

61" LENGTH

19" HIGHT

23" BASE TO TOP (SLANT)

24" PORT LENGTH

4.5" PORT HIGHT

Wow, surprisingly, before port and displacement, you have 15.4 cubes. So that should fit three 15"s perfectly.

Port depth?

 

[guitarman626 10+ year member]

port depth is same as bottom width, minus maybe an inch or two
