IXL 18.4 HT sub

[BiNarY 0]

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.

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.
