It may be, but as previously discussed in this thread, positioning (of the sub and/or the listener) may also help solve your problem. As well as running your sub hot, EQing it, etc. However the first question we should have asked you is: how big is your room? This is generally what decides how much output you need, along of course with your listening habits (i.e. do you listen close to reference level or way below). Note that you may feel you lack bass even if you're listening at low volume.

You specifically said that you wanted to get realistic rumbles, and the key to that is to have plenty of output at 20 Hz and below. So unless you have a relatively small room, I think the answers you already got is pointing in the right direction: you may indeed need more than just another PB12-NSD, which would add 3 to 6 dB to your current setup.

In other news, I think my first SVS sub, an SB12, has a serious problem. At higher volume, distortion is clearly audible even with the limiter LED not lighting up. I'll contact SVS / Sonicboomaudio shortly (I'll try to make a video first), but do you guys think it's most likely an amp issue (e.g. busted limiter) or can the driver really be damaged?

My guess would be the amp. Real hard to break a driver, unless you are playing it stupidly loud.

That's somewhat reassuring as we were nowhere near reference level (but who knows -- the sub was hot by several dBs). Can the limiter even be "busted"? Anyway, I think it's time to call SVS and SBA... I'll report back.

My room is 21x12.5x9. Part of me wonders what ROI I would get out of more bass. I cranked up the db by about 3 and it shakes the room and I go, that's good enough. Then I read something somewhere where somebody said how great the sonic cannon scene in the Incredible Hulk was with their sub. I tried it with mine and wasn't impressed at all. Maybe I am missing something. The opening in Toy Story 2 is much more impressive.

even at that it would be hard to hurt a driver especially with svs heavy distortion limiters built in the amps.

Well as stated above, distortion is clearly heard while the limiter LED doesn't light up. Anyway, as soon as I can take a video of what happens I'll ask SBA and SVS and I'll report back here.

I'm just trying not to saturate the mic in order to record the distortion as we hear it, while showing the LED.

That does not mean the driver is bad...a bad cap on the amp will cause that. A blown driver will normally rattle if the spider or surround becomes detatched. If the voice coil burns then there will be no sound.

Hi Neutro -

Just send us a video (with audio) of the subwoofer making the artifact and we'll try to determine whether it's the driver or the amp. Either way, we'll make it right and the SB12-NSD is super easy to service in the field - a driver or amp swap literally takes minutes. Sorry for the problem and looking forward to your email. Send it to custservice@svsound.com and attention Ed Mullen and I'll be on the look-out for it. Thanks.

I've never blown a driver nor an amp before so thanks for the list of symptoms smile.gif I wouldn't describe the sound as a rattle, and there is still plenty of output, so I hope it's only the amp.

I'll sure do as soon as I can, and will send it to Mason as well as you. I've already performed a remove - reinstall of the amp on one of my Plus, so if the problem is only with the amp, replacing it on the SB12 should be real easy indeed.

The SB12 I had for a while for a review.
The noise depends on several factors. Test time that I had, the dsp hit the brakes effectively and leave a compromise between a given spl and a certain amount of distortion thd full (if I'm not mistaken, every day I learn something new).

The noise can be either a problem in the amplifier, a driver problem, or possibly some audible distortion, for being a sealed enclosure, this type of design makes the driver itself to lower frequencies, the distortion is more palpable, as tamien increases your tour max (at least in my tests and impressions with this subwoofer sealed subwoofer or types).

Just a comparison point: I was disappointed with what I was getting out of dual Pluses in a 1650 cu. ft. room initially, and tweaked location and EQ for weeks before getting (of course) outstanding results. So running the sub a tad hot, tweaking the location, and EQing it can really change how it sounds.

As for comparing scenes, it can be tricky. Some scenes are much more impressive on some subs than on others depending on the sub's capabilities and the frequency response achieved in-room, and also, the volume you listen the scene at. The Hulk sonic cannon scene is much more impressive now that my sub setup is tweaked, but it's far from being the most impressive in my personal opinion. I haven't watched the Toy Story 2 opening though, so I can't comment. An example on how scenes sound different: the Pulse server room scene is not that impressive on the SB12 (and I suspect it is responsible for the possibly busted amp!), but with the dual Pluses in 16 Hz tuning, it's one of the strangest, most impressive use of bass I've heard in a movie. Yet the gold standard is probably the Pod Emergence scene in WotW. There is such a wide variety of LFEs in that scene, it's unbelievable at high volume.

Your room at 2362 cu ft is not particularly large, and unless it's actually open to another large volume, it falls squarely into the "medium" size. For a sub to be "medium-size" certified by Audioholics, it has to satisfy the requirements listed here. It turns out that your sub (PB12-NSD) is large-room certified. So I suspect that you could squeeze a bit more out of your sub if you find it a bit disappointing.

Hi Ed and other educated SVS folks,

I run two SB-12NSD's in second floor room. One of the walls is open to stairs.

The size is appropriately 23 (width) x 15 (length) x 9 (height)

I spent time with a mic trying to find the exact locations to compliment eachother (using roomeq).

The results were this graph:




It seems to be +-1.25 db's from 20-80hz. The front sub has great low end response, but falls off around 60hz, the rear sub has great mid to high end response, but falls off below 40hz.
I did this (maybe I was wrong) provide a blending of the two. I don't get any localization with this setup, and have an overall good band.

Moderate playing music sounds great, as the volume comes up there seems to be a little lacking (maybe a personal taste), I think because each sub is only interacting at the specific frequencies with the middle being the merged point.

I found a 3rd location is the room that is better then both the current locations. It's VERY stable from 20hz to around 70hz naturally without any EQ(center of the room, left of seating).

Would I be better off with a single SB13 ultra in this location versus my current setup?

If I did two SB13 ultras. I'm not sure where the 2nd would go, the first location is great from a overall response stand point. The other locations not so much.

I thought it was big enough for my room size. I have been researching a lot and think it may be a couple things. Placement, which is front left corner right now, or lack of acoustic treatment. I don't know if I need bass traps or not or something else. Here are some pics.

I'm starting to think if I need a new receiver or if my subs are the problem. I was recently watching Snitch on dvd at a friends house and the movie was full of bass from the gunfire and the semi truck crash at the end. During the crash scene, it has this bass tone that was loud and only continued to get loud. My friend has a simple HTIB that only plays dvds. In my room, I have onkyo 805 with definitive tech speakers and a pb1000 and an older pb10 that are level matched. My room unfortunately is squared at 13x14x9 while my friend has his setup in his living room that is open. I sit roughly 3.5ft away from the rear wall and have the room fairly treated. Replaying the scene in my room, the subs don't produce the same bass I heard at my friends house. In fact, I often find myself wondering where the bass is at. I have speakers crossed over at 80hz and both subs are not cancelling each other out, that I know of. I calibrated each sub and speakers using the disney wow disc and I can certainly hear the bass when I use the sub test, but why is it gone from movies? Everything else is crystal clear and have no complaints, but I just don't understand how a simple htib sub is louder than my dual svs subs. Could his sub just be boomy and my subs are just flat or close to it from the acoustic treatment? The subs do play and I hear bass, but it usually isn't chest kicking type bass. Any ideas?

I'm not convinced that switching receiver would give you better bass

well my thought was that my sub out was failing or something. I am using a y cable for the subs and thought that having a dedicated out to each sub would fix it or maybe, it's another issue. I don't understand why they wouldn't reproduce the same bass a lesser sub does, either that or I'm underestimating the potential in these subs and should run them hotter. I calibrated speakers to 80db and each sub to 83db, according to Disney, and then turned both on, which gave an extra 7db, but figured that's hot enough.

Without room measuring capability such as what REW offers, one will never know.

On my part, the simple guess would be, you're sitting is some sort of bass sucking null in the impact zone which is the 40Hz to 100Hz range. The alternative possibility is you have some sort of bass hump that's hiding the impact bass. Without room measuring capability, nobody can say for certain.

Do you have room measuring capability?

Just saying, folks confuse a musical subwoofer set up with a Home Theater set up and these are two totally different creatures.

In the case of Home Theater, one is not suppose to notice bass as one would notice the bass of a music piece. Home Theater is tracked as a "sound effect" and one wants their system to respond to the effect and then go away to always be available for when called upon to reproduce the next sound effect.

If playing music, and one wants a pronounced bass line, cool, run it hot. if playing a Home Theater sound track and one is constantly aware of an overly pronounced bass effect, unless wanting the gals to sound like guys, then the bass is being run too hot as now it's about bass and not reproducing the sound effect. In the case of bass and movie based sound tracks, bass is not sugar or salt where one seasons to taste like one does with music.

Based on what I've read multiple times, this is where the conflict lies and without one having room measuring capability, one will never know what is happening with the interaction between what their subwoofer system reproduces and how this reproduction plays and gets along with the room's acoustics.

Lol @ upside down pic. Anyway, looking at your room, it looks like the PB12-NSD would have no trouble in it, so I'd definitely look into other avenues before sinking money in more subwoofage. That being said, adding another sub *would* be beneficial, but in terms of getting a smoother frequency response and better uniformity more than getting more output. Before we dig into what can be done, not sure if you mentioned what you have in terms of AVR? Do you have any subwoofer EQing capability (e.g. Audyssey)?

Could his sub just be boomy and my subs are just flat or close to it from the acoustic treatment? The subs do play and I hear bass, but it usually isn't chest kicking type bass. Any ideas?

I had the same impression with a good friend who is using a Pioneer HTIB once. The sub seemed suprisingly potent for such a large room. And keep in mind, I'm running dual *Pluses* in a small room. Of course, the smallest SVS sub can wipe the floor with that HTIB sub, and I could fit the entire HTIB sub in 1/3 of one of my cylinders. So what's up with that? Here are a few hints:
  • HTIB subs are indeed potent but for higher frequencies. They simply cannot dig down below 30 Hz, but at 60 Hz say, they are ok and can produce a bit of chest thump and satisfactory results for music, unless pushed at very high volume. But yes, they're typically quite boomy.
  • HTIB setups probably have an internal EQ that boost bass and highs to give a more impressive listening experience at the volumes they can handle. You have a setup that can be calibrated to be flat and play at reference level, which is not the same at all. Flat can lack flavor when compared directly with something that have a heavily skewed EQ.
  • You can run your subs hot. This is actually not illegal.
  • When listening at volumes below reference, bass should be boosted to be heard correctly. In systems with Audyssey Dynamic EQ, the dynamic EQ boosts bass and highs (giving the FR a smile-shape) more and more as the volume is lowered. It's hard to believe how much a bass boost is given by Dynamic EQ at low volumes -- it's several dBs. You can do the same in your AVR (I think the 805 doesn't have Dynamic EQ?) by using the loudness option and/or adjusting the bass setting.
  • You may have another setup problem, but it looks like every thing has been taken care of on your side.

On my side, with an Onkyo 818, I got a relatively flat FR that has very little bass at low and moderate volumes, unless Dynamic EQ is turned on, in which case the bass becomes thunderous. This is only EQing of the source. On top of that, when I raise the volume, I like to have a bit more tactile feeling so I use a MiniDSP to add a "house curve" that boosts quite a bit the very low frequencies (below 30 Hz). So configured, it's night and day from when I was using another AVR without Dynamic EQ: the AVR was totally awesome, but I was too shy and didn't want to touch that loudness or bass balance setting by fear of throwing the EQ out of whack. It turns out it's essential if you're listening below reference and want to have some fun with your subs, IMHO.

So my friend was trying to make a movie of the SB12 making those weird sounds I spoke of earlier. In order to better see the driver, the grille was removed.

Guess what? No more bad sounds.

So after all, not a driver issue, not even an amp issue. It's a grille rattling issue. One one hand it's a great relief -- the sub sounds fantastic even at high volumes with the grille off. On the other hand, recalling the wave of similar problems a few months ago, I'm not sure how easy to solve this will be. I'll contact SVS and SBA soon with pictures. But the troubling part is that it never did that before, so I'm not sure what did cause the problem. The sub is used more intensively right now so maybe the higher levels just made the problem manifest itself.

The grille itself looks to be ok: placed on a table, the four posts touch the table, so the grille is true. But there seems to be no way to make the four posts go inside their holes all the way on the sub. The two upper posts fit right in; the bottom right post almost fits in, the bottom left post does not fit. The grille doesn't touch the ground so the rattling is probably due to the post rattling inside the hole. Inside the holes, there are metal bits arranged in a radial fashion to hold the post. In the topmost holes, everything looks alright, but in the bottom holes, the radial pattern seems worn off.

On one hand, this looks like a relatively easy issue to solve. Barring any other solution, I guess it should be possible to jam foam somewhere to limit rattling. But the grille is wanted on the sub so using the sub without it is only a temporary workaround.

If anybody in this thread managed to solve the problem: how did you do it again?

Indeed, but in his case, the grille was *falling off*, not simply rattling. I remember reading about other members with grilles not fitting properly and I just wonder if there was a universal fix for the problem.

That has a metal grill, correct?
