sealed vs vented subwoofers


I'd like to ask the forum what the primary differences are in sound, performance, and application of sealed powered subwoofers vs vented either bottom vented, rear, etc. B&W makes most if not all of their current line of powered subs sealed. Yet I see other manufacturers offer vented subs. What is the difference? Do the sealed subs produce a higher quality tighter controlled bass vs a more sloppy reverberating type of LFE out of the vented types? Thanks.

Um, I've sold just about every kind of sub on the market over the years, and owned a variety of both. I'd say that, overall, the more musically accurate subs I've come across where "sealed" designs. But then I've had some excellent ported designs.
I would say it depends, and that you can get excellent perfomers on both sides. Sealed usually offeres a tighter more accurate response, seams like, while efficiency and output definitely seem to go to "the port". Still, I've found I can get good results with both. But, if I had to, in a music system, I'd likely lean to sealed. In an HT system, where all out output mattered, or in an undersized application in a larger room, I'd look at ported. Depends.
My favorite music/ht sub thus far has been the Paradigm Servo 15, hands down, in the past. But, I've had some very expensive sealed MTS infinity subs that were stellar as well. So, a lot has to do with design considerations, I'm sure.
I'm no expert speaker builder though...just an observer - lol.
Um, does this help? I can't tell.
