I apolagize...I ramble but I type what I think.
I am contemplating building a sonosub or two for the house that my wife and I will be renting.
The threads I have found have answered alot of questions...however I still have a few.

It will need to fit behind my TV stand. (40" from floor to top of tv + maybe about 7"-9" with DIY center channel ontop) So lets say I made a sono sub that was 50" tall including the mounting feet on the bottom.

Approxamently how many cuft would this net for me?
Can I produce a low tuning (sub 20 hz) in a tube this short?
What length and diamater of pvc would I need for this?
What are the required subwoofer specs required for this setup?

One other thing...Could I possibly connect 2 other sealed sono tubes of the same height on either side with 6" PVC to make a larger chamber to equal the same air space as a a 7' tall tube? (think of how the y-wing fighters on starwars look)

What are my design options if I decided to go with a Box style enclosure behind the stand but wanted a llt.

I understand sub enclosures but...I think I'm missing something on what makes a sllt so different.
