Well Ive done it, inspired by all the posts decided to give DIY a try. Built a 22"x22"x26 sealed cabinet and installed a Sound Splinter RLP15 powered by a EP2500. Just hooked it up and like I have read several times it seems like very little bass is coming out. I have the EP2500 turned up all the way and it seems very light. I think like others I am not used to such clean bass and seems maybe a little break in is necessary. Looking forward to tomorrow to try a little more volume cause its only been 5 or 6 hrs since the top was glued on. Hehe

Looks like you did a great job.
You're bass shouldn't be "light", it should be very impressive. Check your wiring. The first time I hooked mine up, it also seemed like something wasn't right. I'm not sure what I did to fix it, but I checked all my wiring, cut new ends on the driver side, and was blown away by the performance.
Are you getting the lights on your amp to flicker? You may need to turn up your receiver channel volume. If the lights on your amp isn't flickering during heavy bass like War of the Worlds, you got problems with something other than your sub. The lights might not flicker with music, so use one of the monster movies.- Bottom

Send some pics on how you hooked it up, that might help.Danish- Bottom

The signal lights are flickering when I turn up the volume during music. I think I need to turn up the receiver volume to the amp. Now where is that manual? I hooked up the driver in series with the positive lead to one coil and the neg to the other coil neg and the neg from the first coil to the positive on the other. Shew I think I said that right.

A custom cable - RCA to 1/4" or RCA to XLR? RCA to 1/4" adaptor, etc...
I set the mode switches on the EP2500 to 2-3-8 and 9 to on and the rest to off. Is that correct?- Bottom

It's takes the suspension a while to loosen up.
Looks like there's a bit too much damping material.
The way the braces are made you've created a tunnel. If possible it would be better if there was a way to cut additional openings in the braces, or enlarge the sections of the circles toward the corners of the box

I don't think the XLR would be a significant upgrade in this case, you could try both ways and see what you think.
I had trouble when I tried to use one of those adaptors, same problem - sound was very quiet. I built a custom cable to go from RCA to 1/4" and it fixed it.
Not sure what the exact issue was, faulty adaptor maybe???Danish- Bottom

I've used those and they're fine.
Also you may have a level matching problem between your sub out and the EP2500. How high is the sub output level setting?

Play with your room placement. Run some sweeps to see where you get the best response, or at least the response you like best.
You're sub won't have a ton of low end rumble without room gain. Putting it into a corner may give you that. Mine isn't in a corner, so I get a nice uniform response, but no room gain down low, so no rumble. Therefore, I got three filters on my BFD right now, +6 @ 20hz, +2 at like 23 and + 2 at like 28. It adds most of the rumble I desire, and doesn't take away from music. One of these days, I'm going to play with a DEQ or BASSIS and see the differance. But, I'm happy for now.- Bottom

The woofer output level is now at +2 what should it be?

Glad you got it working!
I usually set the gain on my sub amps at about 1/2 - 3/4 position and vary the processor level accordingly. I don't know if that is the right procedure, I just try to find something that's a happy medium (range-wise) for both pieces in question.
I usually end up with the processor level right around the midpoint, +/- a few dB.Danish- Bottom

It's very possible in that size enclosure there is more to be had with backing it off some? Very nice though. :T- Bottom

The box came out so dang big I guess I was trying to take up some volume.
The greater the amount of damping the larger the box appears to the driver. Less damping makes the box look smaller.

Steve and Thomas thanks for the insight, I destuffed the snasauge and I have foundation rumbleing bass at lower volume on the amp.- Bottom

If you build a larger box ie the 22x22x26 as above then you would need less stuffing than if you built a 16x16x16 box, since the 22" box already is a good size? Is this logical??

I agree the idea is not very intuitive; it might be helpful to know that it has to do with the fibers of stuffing absorbing heat energy as the air inside the enclosure is compressed. So the air tends toward a more constant temperature, behaving as if it were not being compressed as much as it really is - just like what would happen in a larger cabinet.
That's a pretty crude explanation and I hope the resident engineers will forgive me. I can't pretend to know anything about gas physics, but it sets my mind at ease to know there's something in there that makes a bit of sense.Paul G- Bottom

Well I watched my first movie last night. It was an action movie called state of the union and I am very pleased with LFE results. I had to turn down the bass to pacifiy the wife and dog. Cant wait to see what this thing can really do, havent had the house to myself much yet.- Bottom

I like the look of that and would love to leave the driver exposed, but you obviously don't have a 2yo running around with pencils and forks in hand :E- Bottom
