I have been debating on what to do with the Mach 5 MLi's that I bought. After debating on the decision I decided to try to design a Transmission Line from them . Heres what I came up with.

Its a Transmission Line enclosure tunned to about 52Hz. Now I dont know everything about designing enclosures but I read all that I could and tried some things that I thought were a starting point.

The box is not nearly finished yet. I still have to add a tweeter, crossover, experiment with stuffing, and put a finish on it. But it is done enough to give it a listen.

Listening to I am fairly pleased with the way it sounds. It almost plays low enough to not need a dedicated sub woofer. It is still a work in progress and I need to build another one to make a pair once every thing is figured out.

Have you thought about actually using them as a sub? Can you tune it lower?

I'd be interested in your design if you wanna send it my way.

Did you use MJK's tables or what to design it?

Heres how I went about it. I started by reading this simple tutorial.

Then I read all of MJKs pdfs on his site.

Then I read info on this site.

More particular that really clears up MJKs findings and adds some others.

After all that I felt somewhat confident enough to try a design.

Cool, those should excel down low. What do you plan to mate with them?

Nice job! On a personal note, look into getting ribbon tweeters for it. I find they mix well with the big HiVi's I have.

Best,

Very cool idea. Would be fun to run a MTSS set up with 3 MLI-s per tower. 2 enclosed somewhat like this and 1 run as a mid bass.

[mrogowski 6]

Actually, that's a pretty good idea. Let me know when you're finished it.

Man, I hate winter....

Very interesting. Im guessing you could un flold it a little bit to make it a floor standing design and retain the tuning frequency? Im eagerly awaiting to see what you've come up with for the x-over...

Also how does having two woofers affect the line length, if at all?

Thanks for the compliments. As for finishing them heres what I have planned.

I plan on making an enclosure in the shape of a trapezoid on the top of it(end opposite of the vent opening) to enclose the tweeter and crossover.

Tweeter I was looking at is this.

For a crossover I was looking at the premade ones from PE or picking up board from Radio Shack and making my own. Im open to crossover point suggestions. I was thinking about 2khz

For finishing on the enclosure I was thinking of this.

Looks good. Can you post your T-Line simulations. Where were you planning on putting the tweeter.
