RE Audio xxx 15'' enclosure help

yea idk i have an 2005 xxx 18 i used the spec from the site for the newer one and i got it in a 4 sealed. I would do prob 5 ported to 34

i can design and build a box for you youll have to pay for the shipping also

3.5ft^3 with a 28-30hz tuning.

If this is the new style XXX, I have the same sub. Go with a large sealed box. Around 4 cubic feet sealed would be good. If you want to go ported, you need to go big. Like ~7 cubic feet big (net). Lots of port area and tune low. The ported box I had was 5 cubic feet net tuned to 31hz with 69 square inches of port and it had a very peaky response. I took the same ported box, sealed the port on it and the response was much smoother. Much better low end, too.

Ikr. Its confusing I built one at 33 hz at 5 and it sounded good but im a amatear at this box building stuff. It had holes and was leaking everywhere. I had it ported. I need one real good design. I want wood size etc, to give to the guy im going to have build it. I am willing to pay for this info. Any help would be appreciated.

some liquid nails would fix that up good lol. glue & screw shit together, then on the inside run a line of liquid nails.

If you would have gone smaller and tuned lower it would have cut down on that peak quite a bit. Going with a larger box is going to make it more peaky, so if you're tuning that high above the sub's fs, it'd be better to go with a smaller box to tame the peak a little. I wouldn't even think of tuning over 30hz with this sub, and I heard they're pretty much useless above 60hz, so you better have some good midbass to keep up(or at least try to).

and what do you guys mean by peaky response?

Like a big gain in output in a certain area, say 40-50hz, but then a noticeable drop in output down below that. I like to have stuff seem fairly flat down to about 30hz so you won't have to really adjust you sub level or bass knob when going from song to song.
