Are big subwoofers viable for 2 channel music?

The OP was asking specifically about home theater and the psa S7201. Thanks for the correction big_greg.

That psa S7201 looks strangely similar to ’stacked’ pro style marshall amps I’d see at concerts when I was a kid. I must be having flashbacks!

Sealed subs sound wonderful and have a massive mean ass bass attack without cuffing. And that is not to say all ported subs have cuffing. I especially like and prefer forward firing subs.

Hello tyray,

     The correct term for a distracting sound coming from the ports on some ported subs is chuffing, not cuffing.  Chuffing does not occur on sealed subs because no port is utilized.  You are correct, not all ported subs have chuffing.
     The conventional wisdom is that sealed subs are best for music and ported subs are best for HT.  The Audio Kinesis subs I use have port plugs so they can be operated as ported or sealed subs.  
     With these subs, I don't perceive a distinct advantage on music operating all 4 as sealed.  I operate mine without the port plugs as ported because I think they sound equally as good as sealed and the bass extension goes slightly deeper.

@tyray Actually, he asked about subs for music that would also work for home theater.  "Now my main focus will be music"

@noble100 I found the same with my 4 AK subs, without the port plugs they sound very good so the sealed vs vented sub dilemma I have a feeling it depends on other things, maybe the dimensions (length and diameter) of the port in proportion to the enclosure? Not saying sealed is not good, just that I assumed for music sealed was always better and Duke prove otherwise.

It is funny you said "they sound" the beauty of bass in my system is I forget about the subs, I don't tweak them, they are part of the room's furniture, I totally forget these exist, I don't "hear them". The only time I realize they are there is when I play rock and my wife starts screaming because candles and ornaments she put on top of the subs start falling off, otherwise to me they don't sound.

And again I'm not trying to promote my subs, PSA, rhytmik, excellent gear which I respect, but (again) quantity (4 or more) and ability to integrate them is more important than the actual brand.

Just that Duke of Audiokinesis if I'm not mistaken was the 1st "commercially" to approach the array, the concept and theory comes from Geddes I believe?

Oh ok, thanks again BigG! In that case I would recommend @smodtactical to get vented subs - and chose a manufacturer, shop or store that will let you hear them whether it be walk in and or has a decent return policy.

Also note that audio stores that are still open - now will a great time to go and listen as hardly no customers will be frequenting the store and you may get a chance to hear the differences between a sealed, vented or ported sub in a very quiet place to judge for yourself.

But if you do get a chance to hear a vented, ported or sealed sub - do so. Don’t take ours or anyone else’s word as a fact. Listen for yourself.
