i typically tune to 25-27hz unless I get an awesome woofer that reproduce subsonic frequencies, than I'll tune to 18hz.

Thanks. I was thinking around 25hz with a 12" RE SE.

26hz on my fi Q sound **** nice and deep, i should try even lower :D
for movies, 17 -24Hz............. music 24 -28Hz or sealed. for a 50/50 of movies and music, maybe a large sealed, but idk

As low as you can get and still sound good. You need to factor what the driver/cab can do, what freq your main speakers cut off at, how much efficiency do you loose by going that low, and at what point does the resonace in the room just become a distraction.
Even if you could do a 12 hz tone at 90 db, most rooms would rattle so much it would be annoying and distracting. If your main speakers are only good down to 100 hz (common problem with small drivers), then you better have something that will reproduce 100 hz - 50 hz and not worry so much about the low twenties and teens.
I've seen alot of HT's with dual 4" drivers in the mains that can't do 180-80 hz for ****, and a sub that thumps at 50 hz and I find it annoying because of the huge holes in the spectrum.

didyouhearthat got a point here. On some movie, pictures on the wall and the wall themselft start shaking so much and you don't really hear the rumble, beside the rattling sound or everything that touch an hard surface

Audio engineers understand that at a certain point when the speakers are good enough, the room itself becomes the limiting factor to sound quality. Improving room acoustics can lead to a dramatic improvement in sound quality if you have decent speakers.
Still, I'd love to build a few giant sonotube towers with 18's tuned down to the mid teens.
