There we go... im thinkin its an IB setup versus a sealed box.

 

Variable volume boxes, and switchable ported to sealed boxes, as well as movable ports to adjust tuning frequency have all been done.

But my box is none of the above...

Those are done without cabin gain thrown in, but since that's a function of frequency, it would effect both curves, equally (at least in a program, anyway).

Toby

 

Nope, did that already. It is definitely based on a sealed enclosure.

I'm not going to tell what it is...you'll have to see it. Or, if it doesn't work out, this thread will be deleted, and I'll say 'what box?'

As I've learned, things that look good on paper, don't always work out in the car, but this one looks good.

Also, I'm not reinventing anything, or doing anything that hasn't been done before. Sometimes, you just have to dig deep into speaker enclosure theory.

One more set of clues...it will be built out of regular MDF (or MDF and Plexi), will use regular speakers (either Crossfire or Oz), and will be powered by normal amps.

old school tech - toby show these kids how we use to do it in the old days..........

 

lol, i know you did. But When I was at the previous meet, toby kept pullin your chain and saying you only hit 115 (or something stupidly lower). We just went along with him

As for toby's box. I can only guess that its probably a huge sealed box (probably 4 cu ft.) I'd suspect he'd get that boost with a Phoenix Gold cyclone, but a regular sub, I don't know.

 

I wanna see this bitch it is probably the size of my car.

 

Like you have any clue what the enclosure even is.

 

Its built. While its not small, its not huge either...36x24x13.5 outside. I'm going to try and put it in my new 'shop truck' for the meet, but I'm not sure I'll have time. Hopefully, I can power it up in something.

When we see it will you even explain to us how it works? or is that a secret too
