Subs: sealed vs. ported


I need to add a sub. I don't have one now, so I'm not replacing anything, and I also don't have much in the way of preconceived notions. My reading is making me think sealed is preferred for music/2.1 channels, and ported is preferred for movies. Is this a fair assessment. I know everyone will have their own preferences for brands/models, and I'm open to suggestions, but it seems my first decision should be sealed or ported (or one of the brands that has ports and comes with plugs?)

The main benefit of dual subs in my opinion is having the ability to balance the low frequencies throughout the room, especially for music. The downside is you might find yourself looking for another black box to EQ the subs (more boxes and $$$)

I'm personally a fan of sealed subs. I've run a pair of SVS SB12s in the past that offered a great sound (smooth, muscial, well integrated bass)and impressive build quality. In addtion to the REL line, I would suggest taking a close look at the SVS SB13 Ultra.

I'm currently running a pair of HSU ULS-15s. If I can help with any questions about these, feel free to ask.
I've found a used ULS15 that I'm considering. I've looked into the SB13 as well. I'm leaning towards sealed - it seems when I'll care most about sound quality, sealed will be better, even if there's a trade off during movies. Hopefully, since I'm not used to having a sub I won't miss anything.

On the ULS15, Yakbob, do you use the wireless hook up, or is that just a gimmick that costs sound quality. It's not a big factor for me, but I was thinking it could at least help as I go through the placement ordeal. Find the right spot, then hardwire the sub?

I'll check out the REL's as well, since they seem to have a lot of fans. Thanks again..
I have a SVS PB13 Ultra in piano black in a 14x20 basement. Simply amazing for movies and music. I had a platform from HIFI Pyon custom built for it and I now have an AS-EQ1 to calibrate it to my Casta Model A speakers. I find the output of this sub to be incredible. Ive owned a Paradigm Servo 15(sealed) and a M&K MX350MK2(ported-pushpull) and the SVS just eats both. Ive thought of going with two SB-13 Ultras(sealed) but I'm told for movies my sub would allow more low level output compared to the two sealed subs. If down the road I wanted more I would just get another PB13Ultra or get one SB13Ultra and have the best of both worlds.....Big thumbs up for SVS...Definitely Recommended..
Yeah, I'm not doubting the grin-factor with the SVS PB13 Ultra, or the SB13 Ultra, or really any of the 'real' subs out there, especially since I have no reference. And I'm guessing that placement/integration will make as much or more of a difference than the variances between brands?

I'm not a cheapskate, but I like deals as well. So right at that point when the money's burned almost through my pocket, whichever one I can get 'the deal' on will likely find it's way to my room...leaning towards sealed, liking the SVS, can't shake the ULS15, even though I have seen some disparaging comments on HSU, I can't ignore the reviews either...(There are those who would call a Krell amp 'crap'...;)) Not having much luck finding REL, although eBay has one in Florida for $700, an R505? Any comments on that?
Yakbob - Any input on an REL Stadium III for $1700? One just popped up within 15 miles....A little higher than I wanted to go, but for a one time purchase...?
