Hello guys! Long time lurker here that finally got the guts to do his first post. I'll get the straight to the point, I'm split between either getting dual XS-15s or dual XV-15s for my room. Would sealed subs work better in a small room like mine (about 1200 cubic ft)? It says the XS-15 would go down 26hz but would it go lower in room like mine? I mainly watch movies so I like my bass to vibrate the seats but I don't want boomy sound. I had a BIC PL-200 so I feel like I was missing a lot of lower stuff (well at least from what I've read here). Any input would be appreciated smile.gif

If it is I would opt for dual xs15s personally that way u have more freedoms of movement for freq smoothing

In general, with comparable subwoofers, with a properly-made vented one, you will get deeper, flatter bass, until it starts dropping off, and then it will drop off faster than a sealed subwoofer will.  You also tend to get higher output before the drop-off.  With these, from looking at the manufacturer's claims, I personally would go with the vented versions.

With a longest room dimension of about 20 feet sealed is OK, larger than that ported is better.

I would get the ported. In the future, you may want to use it in a larger room.

You have to be careful when comparing the +/-3db Frequency Response of a sealed subwoofer. That rating simply tells you how low a sub will go while maintaining a flat response with out any boundry reinforcement. Place that sub in a small sealed room where 12db of room gain can lift the low end, then you have a sub that may reach +/-3db down to 12-14hz.

Ported subs generally follow thier base response because of the steep roll off below the tune. Room gain can still affect them but normally excessive room gain of a ported subwoofer will cause an big Peak in the response between 20-40hz. Also extension may increase slightly but normally never more then 5hz.

Exactly. The f3 of a Psa xs30 is 23hz (according to tom)

In my room I get extension down to 10hz +\- 2.5.

When I had a xv15 in my room which has 18hz as it's tune. I was getting extension down to only 15hz.
