Yeah, I didn't think it was the driver. I did the crawl when it was in the sealed box, but not in the ported one. It is in the spot that sounded the best out of limited placement options I had (three), although in the ported box its too big to go anywhere but beside the couch as an end table so...

Ok, so I "finished it" and dropped the sub in for a test run for a few days before I try to turn it into an end table. It definitely gets louder and lower than it does in the sealed enclosure. It really gets loud between 30 to 40hz and then my lows start to pass off to the mains. It sounds a...

That's fair. I don't know much about vent air velocity and ports, but it looked like it modeled well in the PDF. I may round them out just a smidge to try and cover my inability to cut a good rectangular hole in the baffle.. Thanks!

For the flare, the pdf says 2 vent ends... do I do the long sides? The short sides? or does it mean I should flare all sides at both ends of the port? How much flare? Could I just sand the edges a bit with an electric sander? I don't have a router so.. thanks!

How well would this sub work down firing? And what effects would that have on the sound.. If it were firing right into a concrete floor? How far from the floor would it need to be? It would make the sub unreachable by the kids.

This might be a dumb question, but I'm ok with looking stupid. Instead of the Roxul, could I just put a pillow in there? The box is big enough, could I just buy a large poly pillow at Walmart and put it inside the box still in the case to keep any poly from coming out the port? Thanks!

I'm unfamiliar with using rockwool.. why that over poly? Is its purpose similar to poly or convoluted foam? I already have both of those lying around, although I could buy some rockwool if the reasons are good. Or is it just to use something different? How much of a flare for the port? Does it...

I'll caulk my face off... as far as bracing, if I follow a similar method to the pictures on page 3, is that enough bracing? It doesn't look like much bracing compared to some, but is it enough?

I'm finally getting around to this.. My awesome 30 year old table saw and it's rickety guide have caused some measurements too be off. I'm assuming it won't matter much if the port is off 1/16th or 1/8th of an inch here and there?

I am not getting anything near 99db @ 20hz. In fact it drops drastically at 40, gives a weak 30 to 40 and I'd say almost inaudible under 30.. and it sounds like sloppy farts at even moderate volume. To be fair it is in a crappy box. Although I believe it to be an air tight box it is poorly...

My wife and kids are going out of town tomorrow so I think it's time for me to give this a run. Right now I have it in a 1.5 cubed box sealed... and it sucks.. in every single way. Do you happen to remember what dimensions you used to cut the port pieces? or even the box for that matter. I...

Has anybody actually built this box? I think I'm going to give it a run, but was wondering if there was a build thread or listening impressions for it. At the price I can't imagine I could go wrong.
