Subwoofer Suggestion


Hi guys I need your suggestion regarding subwoofers. My system is composed of Focal Kanta 3, Kanta center, 706BK it would be used 50/50 for music and HT. My room size would be 13m by 4m by 3(Length,width,height). Would it be better to go for dual pb1000/sb1000 or single sb3000 or single pb2000 or single PSA S1500?

Kulo, where did you get that name? Hee Hee I just noticed that..

What about PE can you get their stuff where your at? They ship everywhere, I thought..

They have good units you can build from flat packs or they have a few premade units, too.

It’s an idea anyways.

Regards
@kulo  it doesn't have to be T9. Maybe go for the T7? The T9 is more than enough for my room. 
Baylinor I'm dying to try a rythmik sub but sadly there are no dealers here in my country.
I've asked for the price of rel t9i and it costs 1900usd it's out of my budget. 
If you go down that road, DM me and I'll tell you about it

For stereo I use dual Rythmick F12 sealed  subs. Loads of adjustments to make them disappear into the speakers. Plenty of power at 370 watts each with very tight musical bass. They have ported subs better fitted for HT.
I recently added a stereo pair of REL T/9i subwoofers to my Magnepan 1.7i pair. They have revolutionized my system. I’m a believer and vote for REL. Use the high level input. Good luck. 
I have quite a large room (28'x15x10-14', my ceiling slopes a little). I've rearranged this room a bunch of times and have had to find different places for my sub (REL T9). I only use it for listening to music (no TV). I've used the step by step set-up instructions from REL every time I've rearranged this room. I've been able to get amazing performance out of this sub every time. I think this speaks to the quality and thoughtfulness that they put into their products. There's one additional step I take setting up my REL. If you go down that road, DM me and I'll tell you about it. 
It would be underpowered for me, maybe not for you. Forced to choose, I'd take two small subs over one big one for that sized room. 
Testing it wouldn't be possible. So since dual sb or pb1000 is underpowered would it be better if I go for a 15inch PSA S1500?
Can you return them?

SVS or PSA over Focal or Klipsch. The 1000 series SVS subs are entry level and under-sized for that room. If the desired outcome is to add a little more bass, they'll do that, but if you're expecting a major improvement, you may be disappointed. Only one way to find out. Can you return them? 
I just fear that maybe the sb1000 wouldn't go deep enough, and for the pb1000 not to go tight enough. 
Two of the sealed SVS-SB 1000 should do the trick!  

Thanks for your suggestion corelli, sadly, there aren't any RSL dealers here in Philippines. Svs, rel, and PSA are the only ones available to me. Also, my maximum budget that I am allowed to spend is around 77k php which is around 1500usd. Also svs subs are like almost double the srp here compared to the US, so I can't really go 4 subs unless I go for klipsch.
Elliot sadly it doesn't reach deep enough
compared to the Revel studio2 that I auditioned. I've just recently made the purchase, this is my first hi fi system. To be honest, I'm still trying to decipher your response since I am relatively new to speakers. By the way upgrading later on isn't an option since my dad just wants a one and done system.
Thanks for your opinion guys, the dealer recommended the Focal sub 1000 F although I haven't heard it, I'm pretty sure that it won't be
enough for my room and I think I can do better with PSA or svs subs for that amoutn of money.
I have 4 systems - main (living room), office, bedroom, computer room. My living room is pretty big and opens into my kitchen. 4 subs there. All the others have a single sealed sub and sound great. 

If your goal is gut punching bass, you need big powerful subs. That's not what I'm trying to achieve when listening to music (although I have the gear to do that).  If there's bass content in the music, I hear it much like it would sound live. And when there's some really deep bass, it is visceral.

The OP has a big room. Multiple subs are the easy button for well integrated bass if there's room and budget. 
I just auditioned a pair of RSL Speedwoofers.  This is a compact 10 inch sub that has to be the best value sub for the money I have heard.  It can reach down solidly to 25hz, is compact, all for a bagain price of $400.  Shipping and return shipping included!  So get 4 of these subs and you ought to have effortless, smooth bass well suited for a 50/50 split of music and HT.  What have you got to lose?  Highly doubt you would return them

So just using a subwoofer is out
Certainly not.  Do whatever floats your boat.


Oh boy, I sure would like to hear those Kanta 3’s. Extending their bass, for music sometimes? For video sometimes? Complicated!!!

My advice: Stereo Pair of Subs located with the mains to maintain imaging. Careful control of crossover and volume. Self-powered, independent of the video system, i.e. extended bass ALWAYS.

As you must already know with your speakers, low bass is more directional than many think, and it has been pointed out, the narrower overtones of the wide low bass fundamentals give directional cues to the fundamental’s location.
......................................

The better the mains, the harder it is to achieve seamless extension, and you probably cannot personally listen, likely buy un-heard, I would want full return/refund (not store credit).

....................................

If ONLY for Video, adding bass effects i.e. Dinosaur Stomps, a single self-powered sub will work, balanced to be unaware of location or contribution unless you turn it off. But ....

When via 5.1, using sub out, then when using ’direct’ which is often 2 channel, or 2 channel mode, often the content’s original format, the sub will be off, no extra bass. I very often find the cable company or my AVR send/invent/use surround without me choosing it, and 2 channel sounds better. Therefore, for ANY home theater, you still need a decent amount of bass from your mains.

For stereo music or stereo video, extended bass always, a stereo pair of subs is needed, and very carefully chosen and controlled crossover/volume to work seamlessly with your existing mains. They need to be self-powered to maintain independence from AVR system.


..............................................

I suggest you further arm yourself for evaluation.

piano lows, bass, drums: I prefer using stand-up bass to evaluate bass: quality, control, directionality.

my music system: horns with 15" woofers, no sub

my video system, single self-powered sub, via 5.1, mains have 10" woofers for bass without sub, sub far from mains

my office system, bookshelf with single self powered sub, always in. music and video from 27" monitor/pc
...........................

good luck extending those beauties. btw, manufacturer probably has some advice, perhaps knows what other owners have tried/done.

Four small subwoofers instead of one big one.So just using a subwoofer is out now you need multiple subwoofers.REALLY. How about one big one like 18 inches and then a small one in every  corner. Bingo.No wait I have a 11.1 system....speakers everywhere.....Remember less is more.
To put it simply, using more than one sub helps cancel out peaks and nulls.  With one subwoofer, you may have spots where there is too much bass, and not enough in others.  Four small ones would be much better than one big one.  Do a search here for "swarm", lots of discussion and information available. 

Not to mention, you have a pretty large room.
