A 10" that really wanted to be a tempest (1 Viewer)

I got 4 of these from my friend last night, at 30 bucks apiece i don't think they will be that bad. Granted these will be used mostly for music, but they will have huge slam to them.

We put two in a box with a volume of about 2.2 cuft and a port get this 80 inches long with a xsection of 50 inches squared, needless to say the box is going to be huge to accommodate the folded port. And the -3db point is at 50hz but the xmax isn't even touching the 13mm that these have so i will probably slap them on my BFD and bring them up so they roll off around 30ish.

The thing that i really like it the group delay is so freaking small, at 10ms these things will be supper tight, Olsen twins tight!!!

I will try and get the TS that he has for them so you guys can see what you can do for a box size.

Sounds like your woofer really wants either a small sealed box or a passive radiator. With a port 80 inches long, you are starting to get into quarter-wave antiresonance loading. A ported enclosure that replaces the port with a transmission line is called a Daline, or Decoupled Antiresonant Line. The air in the line actually contributes significantly to the output of the speaker, but there are generally more considerations in the design of a daline than just a really long port length. I think you might be disappointed. I don't know. We will see.
