$200 (US) seems a little excessive to lengthen the port, IMO. I remember seeing somewhere on the i'net(Youtube?), some kind of sub which used a fan to move more air, probably some kind of DIY.

There are plenty of fansubs on YouTube, it's true.

It could be more complicated than that. Generally you also want to increase cabinet volume as you lower tune, so maybe they found a way to do that.

There are two rotary subs that I know of, only one of which, the Thigpin, is still in produciton. I would love to hear this one in action as it is supposed to be in a category by itself.

I really enjoy my outlaw, it fills my 12x21x8 room quite nicely. I really don't understand why they don't get more reputation. It will definitely hit the lows as well. In Transformers and Kung Fu panda it hits notes that are barely audible but shake the door and windows.

Do you own an spl meter by chance? It would be nice to see a measured sweep to see how low it reaches in your room.

There are probably a couple of ways to do this. One would be to find some recorded test tones that you could burn to cd to play while you measure and record manually. I have not done this, but I think a couple of other people here have.

The other way is to use a program called REW which has a tone generator built in and is able to automatically record sweeps it generates using an spl meter connected through the computer and receiver.

REW will initially be more difficult as there is some setup involved in connecting all the bits and a little bit of a learning curve to calibrate everything. Once its all set up though, it is dead simple to run.

REW can be found here, The download link is in the sticky at the top of the forum.
