Wacky TL idea, comments?

[sifka4]

Hey. I'm really into subs and would like to build something more complicated than a vented enclosure. I've done a bit of car audio, but I want to be able to use a larger sized woofer for the home (18" or 21").

I read a little bit about El-Pipo and thought about a way to compress the design. I've never worked with sonotube before so I don't know if it will work, but what do you guys think of this?










Could it be done, and if so would it even be worth it? Could it somehow act as a horn because the two outer output pipes combined are larger than the first output pipe? Just throwing some ideas down

It would look really cool, but probably a lot of work... an easy way to double the length of a pipe is to put a baffle down the middle...

Or pipe within a pipe........ Anyway, a tapped horn is a bit more complicated and many car audio sub drivers are excellent for the app and can probably match or beat an 18 or 21 TL with less power required if their published specs are reasonably accurate.

But wouldnt that somehow choke it? I would think with two 21" woofers and a 24" sonotube that this wouldnt be such a good idea. I don't have any experience here though so I could be wrong!

A 24" sonotube is going to choke 2 x 21". Using MJK's ballpark, a starting point for a TL would be a sonotube with a 24" RADIUS.

Looks like a regular vented speaker, with large long ports.
