svs pb-13 ultra

hi all i just got a svs pb-13 ultra. i have a couple questions tho. my room is 12x14 with an 8 foot ceiling. it is quite small. one question is the manual states that you can tune the ports with plugs, but it doesnt describe the effect of sealing up all the ports. does the bass get much tighter? do you lose bottom end? would this sealed application be better for my small room. i also have it fully treated with bass traps and have am external eq to flatten the subs response.

second question, if i tuned the sub to 10hz by plugging 2 ports, will this be a waste of time because my room is not long enough to produce a bass wave that low?

thanks all

The group delay is better when sealed in the lowest region. With such a small room you won't be stressing the driver so distortion should not be a factor. I'd pick sealed.

You mean with out reflecting off of a wall? If that's your concern, then 80 Hz is about the limit of your room.

Your room is small enough so that EQ above the sub crossover would probably be helpful.
