After listening to both SVS and SPL Ultra, I would said that both are very powerful sub but between the two SVS is way better with its deeper and tighter bass. And since both cost around the same, I highly recommend SVS BUT only if you have a large room to acccomodate it cos it's very huge and tall.
So for those who are thinking of getting this huge sub please take note of its dimension before taking the plunge.

I agree with u that the sub should match well with the rest of the speakers. In my opinion, the thing u mentioned about "getting a loud bass that drown the main speaker" is a problem with having the sub volume mismatched to the rest of the system. Personally I don't think it is a problem having a monster sub provided you level match it well.

Think about it, the goal is to be able to reproduce the full spectrum of sound from 20Hz - 20kHz and be able to do it at a specific level. Most main speakers can do 40Hz upwards, it's the deeper bass region from 20-40Hz that we need a sub for. Even then not all subs are the same. My 12Q goes down to 25Hz. If I wanted to hear down to 20Hz, I'd need a bigger sub - there's no way around it. Again just to be clear, I'm not saying that the bass volume is turned up high to drown out the main speakers. All I'm saying is to be able to hear the full spectrum of bass at a level matched to the main speakers.

Secondly about what you wrote: "even his 12Q is already blowing his roof off". Please don't make it so dramatic, I merely said that my ceiling vibrates. What is the cause? It must be the way the low frequencies are mixed on Iron Man. With Kung Fu Panda my ceiling doesn't vibrate. So I guess the soundtrack engineer on Iron Man must have put some really low bass on that scene. Now remember my 12Q is only spec'd to 25Hz, there are other lower notes that it cannot play well. Imagine if I had the SVS, it would reproduce down to 20Hz or even lower and this could cause more interactions with my ceiling. Yes, I would get more bass but it is counteracted with hearing more ceiling vibrations which decrease the quality of sound overall. So until I can control/tame the ceiling vibrations I don't think I will upgrade to a bigger sub.

I wonder if the volume level is the same across different brands of receivers. For me I listen at -22 dB. Of course another factor is speaker efficiency.



Yeah, hard to describe with words. I guess I should find some time one day to listen to your SVS then can experience the difference. Not only how low it goes, but for bass articulation, speed & dynamics.



Interesting to see your sub setting. After running Audyssey, my sub is set at -5dB.



At more than 5k, the SVS is beyond many people's bank account. Glad it didn't break yours... so means you have a bigger bank account than most of us

"even his 12Q is already blowing his roof off" just an expression lah.

Aiyoh, no need to pijak people like that...

alot malaysian house plaster ceiling rattling?

I'm just curious, freq below 30hz are more to audible or being felt?

At 30Hz I think still heard. Maybe below 20Hz will be more felt than audible.

Vibration not necessary is cause by the deepest bass. Sometimes it vibrate due to certain freq. Think of it like a tuning fork. Anyway, talking about value, looks like svs provide the best return. Might ask my friends consider SVS PB-13 Ultra.

PB13 ultra??

i guess need 2 hulk to carry

Moe than 50kg. If door to door, then no problem eh?

It's 155 lbs! Even to unbox might need 2 people, and also for moving position around the room.

I'm one of the lucky persons who was able to experience the 'boom-boom bang-bang' of htkaki's new toy svs pc13+

Svs did outperform spl 1200 ultra. Bass is tighter, more refined and provides more depth. I remember there's a scene where I can really feel the people running down the staircase from far, which spl could not provide. And a scene in Master and Commander where the blasting of canons took place. I felt like the canon is blasting towards my direction.

Other than that, I felt that svs did not outperform spl very much. In certain scenes I could not find any difference between both of them. Maybe just my peasant ears, but that's what I felt.

Giving the same price range, I'll still recommend Svs. But this is a real gigantic thing that will consume up your space. If you have enough space to play around, go for it. Guarantee no regret.

Too bad I will not be able to get this thing as my HM definitely won't approve it. I just bought the CHT-10Q not too long ago, and she'll notice the difference immediately if I change the sub. I heard htkaki said even pb13+ is also a gigantic thing which will break your back if u were to carry it alone. Guess I'll have to settle for spl 1200 ultra as I got a quite attractive deal from A&L for trading in 10Q for spl. My HM won't be able to spot the difference as both of them almost the same size.

A&L is like doing alot trade in for 10Q n 12Q lately for SPL

wonder why?

both are great sub. After hearing them my sub is reproducing a mere "fart".

IMHO, SVS has the upper hand if the audio track has continuous low freq sound. The SVS has no problem building up pressure with its cylindrical design. Velo's bass felt a little more "out of control" compared to SVS (after the first few low freq reproduction). Maybe it is because Velo is moving air that is not contained.

I think SVS's footprint is about the same as the velo, but because the sub height it may be hard to find a good location for it in our HT room that is normally a rectangle, and the front are sitting on 1 of the shorter end. It normally cant sit in between the front as it either be distracting or block the projection screen. Those who are placing their front on 1 of the longer wall of the rectangle room may want to consider the SVS. It could sit snugly on 1 of the corner.

I have 1 of the corner ready to house the SVS, but of course the bank balance doesn't allow it.

Yes, yes. We all have. Few corners also can.
Always ready.

those of you getting a SVS for your bedroom might want to put in lots of bass traps :

sigh....
I felt my 12R no value liao....
