SVS Sealed Subs... - Page 22

I've owned many different subs and the sb13 is no more difficult to set up for good results than any Other powerful small sub. As with any sub capable of high output, you really have to be mindful of room problems because you will be exposing room resonances and hearing the efffects of room decay with more ease. It's size is still quite manageable so it is not too hard to place

Teech teh controversiez! lul

Like the last AVS member who couldn't tame his, damn thing nipped off a few of his fingers.

Cheers for that, early indications show a massive dip at 80hz the crossover although that could be a phasing issue and a massive spike at 50hz which was able to be cured by a -12db peq change. From that point down its quite smooth although my 1300 cu ft room is not giving me the room gain that I was expecing below 40 hz I am currently looking at approximately 18hz at the -6db mark which is probably ball park for this sub....I imagine anyway

Rosie is still with me after 4 years. SB12-plus.

Hi,

What are the box dimensions or 'Rosie'

13.5 X 13.5 X 13.5...with the grill on the depth is 14.5.

Rosie still looks in mint condition.

oh, that is an older pic, but ya, she still looks the same today

SB13 is heavy.

Yes I am pushing it around my room and it is back breaking

$10 worth of furniture sliders is a great investment for anyone moving a heavy sub around.

Any update on the new SB13?

re-released in the Autumn, with new black gloss finishes on all sides.

No hardware upgrades so performance should be the same

^^ price and over all dimenssion?

I would imagine box size same as current model which can be found on their site; price no idea

l thought is was coming this summer?

And is gloss the only option? Thats bad. It gets scratches too easy.

SB13 contest- http://www.audioholics.com/news/editorials/svs-sealed-sub-audition-contest


If the specs are going to be same why the need to test for its performance?

My new SB13-Plus arrived last Friday and I've been using it most of the weekend. It cost me a small fortune to get here (New Zealand) and I ended up having to go and pick it up from the local CEVA depot (delivery was extra, even though I paid US$280 for door-to-door delivery...). They actually loaded it into the back of my SUV (that I had to borrow) with a forklift, on its little wooden pallet. I wasn't expecting it to be quite so challenging given that it's not actually that big.

This sub is built incredibly well. The bass is produces is equally impressive. I haven't had too much experience with subwoofers (I have had a Velodyne CT120 for over 12 years; before that an Energy then a Polk sub) but the improvement was dramatic. It's being used with a new set of front speakers (KEF Q900 and Q600c, replacing B&Ws), so it's hard to tell what is responsible for what (everything changed over in one go). The bass is much deeper than before, but what I like most is just how tight and musical it is. It's the sonic equivalent of a velvet-covered club. I think I'm a sealed sub convert, and I'm even thinking about getting another SB13-Plus (before the Ultra comes out, so I can have two cosmetically matching boxes). I suspect this sub will be joining the few permanent members of my home theatre.

My only suggestion would be for SVS to get someone to proof their user manual. It could really use some work.

Good point. Perhaps SVS has a trick up its sleeve?

The contest rules state that the ability to take acoustic measurements is not a requirement. With that said, some of the more experienced A/V forum members are comfortable taking in-room measurements (like with REW), and are certainly welcome to include those in their review.

But why? We all know how the SB13 performs in terms of measurements and based on reviews, SQ.

Did you guys decide to upgrade the sub? Or are you just doing this because you're reintroducing it?

Yes, the AH contest is fun way to promo the release of the SB13-Ultra. AFAIK no one has done a contest where three respected forum members all get to write reviews and have the forum community vote for which review they find the most comprehensive and valuable (again any acoustic measurements are strictly optional). The contest involves the forum community and promotes social networking, and we're excited about it.

Regarding the SB13-Ultra, as others have already indicated the hardware is the same - our Sledge STA-1000D DSP 1000W amplifier used in the PB13-Ultra and PC13-Ultra, and a variant of the Ultra13 driver optimized for sealed applications (overhung motor topology, a unique VC which is longer and has higher thermal power handling, and a gap extension plate to improve BL symmetry, lower THD, and increase effective Xmax). The cabinet is all new with a full piano gloss or real black oak veneer and a perforated/curved metal grille.

Make sense.

Question, the SB13 comes with a peq right? I forget if it did.

The SB13-Ultra comes with two (2) PEQs (boost/cut, Q value, freq). These are valuable when the AVR lacks subwoofer equalization, or for 2-channel rigs.

Hi All,

Does anyone know if SVS are still planning to launch the smaller SB10-NSD Sealed Sub? It was supposed to have been brought to market last year & there has been no news that I can find. I really hope that are still planning to introduce this model as lots of people still want a smaller sub due to placement & size constraints & it would also be a greta partner for many of the smaller lifestyle satellite speakers that are so prevalent these days.

Nice. I would definitely need that since i have pioneer SC-37 AVR.

Can you give a month when the SB13 ultra will be ready to ship? I was thinking of getting the SB12 then doing the upgrade thing you guys have for the SB13. I need a new sub badly. My current def tech sub has output to only 28hz. I like the way it sounds though in my 1500cu ft room. So either the 12 or 13 is going to be huge improvement.

Also i saw the audioholics review of the SB12 and it was tested to have output to 21hz- http://www.audioholics.com/reviews/speakers/subwoofers/sb12-nsd-subwoofer/sb12-nsd-measurements


The SB13 review from S&V says it has output to 23hz- http://www.soundandvisionmag.com/article/review-svs-sb13-plus-subwoofer?page=0,2

Shouldn't the SB13 measure lower than the SB12? Or this because of different testing procedures?

What kind of output can i expect from both the SB12 and 13 in my 1500 cu ft sealed room?

(I do have windows though)

We did massage the DSP EQ file for the SB13-Ultra, and the tentative FR spec is 22-350 Hz +/- 3 dB. But the bigger story when comparing the SB12-NSD and SB13-Ultra is the shape of the knee and the subsequent roll-off slope. The SB13-Ultra has a broader and more gradual knee and a shallower roll-off slope. This results in less phase change with lower group delay, and it will also take better advantage of available room gain. So in 1500 ft^3 room, the SB13-Ultra will dig deeper than a SB12-NSD.

In terms of max clean output, the SB13-Ultra has about 2X the max clean output (i.e., CEA-2010) as the SB12-NSD, so add about 6 dB to the values showin in Josh's SB12-NSD review and you'll be close. Estimating max SPL indoors at the listening position is more tricky, because of room modes. With that said, each nearfield boundary will typically add about 4-5 dB of additional output, with the ceiling adding maybe 2 dB. Room gain will add about 6-8 dB/octave of additional max output below the modal/pressure transition frequency in the room (probably about 35 Hz in your size room) - so additional max output from room gain is frequency dependent.

We should be taking pre-orders in August and shipping in September. We already have early production samples in-house (see our FB page).

Thanks for the explanation.

Another question. How accurate is merlin? I want the SB13 but it recommends the SB12. Yes my speakers are small but i'll be getting new speakers in the future. Wouldn't the SB13 work with a 100hz X-over for now? It goes up to over 300hz after all.

Since I have experience with the SB12 and SB13, I'll state that the SB12 will be enough, but if you can afford the SB13, you'll love it and not regret it. The real key as Ed mentioned is the shallower rolloff. It's a natural rolloff which naturally complements the inherent room gain that a small to medium room will exhibit (and you can tailor the rolloff in the amp controls to suit your room). With the SB13 in your room, you might get actual real extension down to 15 or even 10H whereas the SB13 will drop off quicker. The SB13 will give you room to grow if you ever want to upgrade your system
