I'm looking to build a serious quality HT sub that will really hit the lows, and with a FS of 15.4 hz thats enough to keep me smiling.

i was thinking along the lines of a rectangular box with a 6" port and roughly 15 cubes tuned to 20 hz, what do you guys think?

gives me a miniscule bump in the low 20's but keeps the f3 at ~17 hz.

i was thinking 1" MDF with a double thickness front baffle, but am not quite sure how to brace it.

(i can't wait for the IXL drivers)

thats what i will be using for an amp,

The buttkicker 1100w @ 4 ohm. (i like the idea of a separate sub amp instead of the plate amp setup because i can then put my sub in my trunk and just hook up the speaker wires when i want serious bass in my car

Hey BiNarY,

I'm figuring on 17 cubic feet tuned to 15hz. I'm not sure if a 6 inch port will be big enough for this sub. I'll have to find a vent speed calculator somewhere to find out. Personally I'm thinking an 8 inch port. The Buttkicker amp is a good choice for a sub amp. Lots of sub builders at avsforums are using it with no problems. I'll be going with a 2 channel pro amp since I'm building 2 of these subs. Can't wait for these subs to get here!

well i modeled it with winisd and it said vent speed would be well within acceptable ranges at 6 inches, but theres no way its acceptable for two. i wish i could find a flared 6" port, i don't have the tools to make one myself, and that sucks.

6 inch ports in Canada are hard to find. One place that advertises for them is http://www.2loud4you.ca/ but the site is dead. No updates, no response to emails. A U.S. sourse is http://www.thrilleraudio.com/. But cross border shipping makes it expensive to bring into Canada. I might have to make my own. If I do I can make one for you too. I've read up on it and it's not that hard.

yeah let me know if youre gonna make it, i'll definitely throw you like 15-20 bucks for it. + the shipping. its nice to have good stuff made

Another option for ports is to use Sonotube - very cheap and easy to get.

Good point. 6 or 8 inch sonotube with a 1.5 inch radius roundover bit and a person can make their own flares. I found some pics of a diy 6 inch flare using a roundover bit and some MDF.

The pics are of a 6 inch diy flare compared to a 4 inch store bought flare. It looks easy enough to do. I think I'll give it a shot.

Mark brought the IXL for HA people, many of whom are IB fans. So I think if in home the IXL, or if in car, the MJ.

Yeah, that's really the best way to go for larger ports IMO.
