IXL 18 meets the "Easy Button"

This is for the folks ready to pull the trigger on the IXL 18.4, or really anyone looking for a solid 400 liter box on the cheap, I plan on posting a revision allowing for a shorter port, for those that might object to the ~37 3/4" oal on the port, the center brace needs to be a little different, a minor adjustment.

If you can set the fence on the saw for 24", 23 1/4", 11 3/8", & 10 3/8", and use a circle jig, your good to go

I've got to give Vito props for the motivation to do this one, I like to go BIG, but this was what made sense to me for his setup.

Stats:

24 3/4" H&D by 49" L

~403 Liters as drawn
6" SCH 40 port of variable length up to 37 1/2" as drawn
Tuning ~11.5Hz as drawn


Looks harder than it actually is
You only need 2 sheets of 3/4" MDF to build this box.



First sheet gets cut into 24" wide strips

Second sheet is cut into 23 1/4" strips

The 23 1/4" strips are then run thru the saw again to make 23 1/4" squares

Take 5 of the 23 1/4" squares and cut 20" holes on center

Take 2 of the peices with 20" holes and rip them down to 11 3/8"

Take one of the halves and rip it again at 10 3/8"


I will post later on the port instalation and driver cutout

If anyone sees a way to do this cleaner, speak up

This box is for YOU FOLKS, Ideas are welcome

Mark,

I'm all about the roundover, but.....
I've olny got a few months of self-taught CAD under my belt, but I'm thinking Google Sketchup won't do roundover on a radius. If you, or anyone else for that matter could help me understand how to do that i'd really appreciate it. I do intend to convert the refined end result into a .pdf file format. I'd be happy to send it your way.

Since you the man to ask, may I have the measurement for the proper depth of cut to flushmount the driver, I'm drawing it with a 16.75" mounting hole and a 18.25" ID recess, but i'm missing the depth figure. I also need an accurate as possible figure for driver displacement, I eyeballed it at 4.25 liters.


Thanks
Dan

Collo,
Thanks, this is gonna be fun.
I never even knew that tool existed.
Mabey someone will arange for a group buy on 1.25" and 1.5" round-over bits, LOL.

Collo,
my puter just went to lunch, I drew a Torus @ 180 degrees of resolution on both axis, that's 32,763 entries. I thought it was never gonna get done LOL

Do you go by Bill or do you prefer Collo?


thanks again
Dan

32" OAL port and revised brace

Mark,
I know i've got dyslexic tendencys, 4.3 liters? 12 liters is huge, like the SD for the driver x 116mm depth, I think your over double the displacement at 12 liters.




Army,
sure 600L and a 8" port looks better for the most part. That's not what this is all about.

For me this box and Scotts RL-p build are about what can be done within the limits of 2 and 3 sheets of MDF, that don't require advanced assembly technique or knowledge.

So when someone wanders in and says, "Hey what box can "I" build that will make that new IXL whip azz in my HT setup?" there will be at least a solid "stock design" to use outright, or as a reference to improve upon.

For someone who is new to DIY it's easier to recruit help when you've got a solid plan. It seems virtually everyone knows someone with most of the tools and enough skill to execute the build properly, and more often than not that builder with the tools has never built a subwoofer due to lack of design knowledge or plans.
My goal is to make the build so easy to execute properly that, when a builder is approached with the plans, it's almost imposable to turn it down. We all know the results are addictive, and once that box is heard it's all down hill from there...


I'll finish the port support details tonight

corejonp1,
Thanks for the offer, I might take you up on it. I need to draw as much as possible so i can get better at it

Adamms,
thanks for taking the time to actually check it out. It is not put together the way you were thinking that's how the panels got to be that way.


Mark,
I've been feeling the same way lately, 24-7

Everyone,
Here's how you cut the port support and brace
I'll revise the instructions above and edit the post

Mark,
thanks

I am such a burnout, now that I look at the port brace, i'm thinking about changing it

I like this much better
