post #10651 of 15693
Gosh. I have to Surrender my Card.

Can I still keep the subs? smile.gif

I use Room Gain Comp on my 99.99% music system. No Room "load up"

IMO? It's a great feature of the SVS.

I totally agree! However, it is another form of eliminating peaks in a room.
post #10653 of 15693
As difficult as it can be at first, to get our noggins around the concept of "Rolling Off" anything in our systems...

It can be helpful to consider what the natural Boundary Gain "profile" of the listening room is doing to the end-result. It's boosting things....enormously so in many cases, just the same an an EQ would. That "ain't right" either.

The Room Gain Compensation can be tailored quite closely to the behavior of your room, and THIS end result is an equally extended Bass performance that is neither understated, nor OVER stated.

Depends what you prefer, and of course...YMMV.

You've already got the feature, bought and paid for...and it's no extra charge to try it out over a range of movies, and/or familiar music, and then see which you really prefer.

Mine is set at 31hz....and I never looked back.

CV,

because you were so helpful with me figuring out my my SB13 when i went 2 channel, you get a pass. smile.gif

Does the bass sound "tighter" when you have it on? My bass is super tight already...but...nah I can't do it! biggrin.gif

I was listening to my PB12-plus tonight and I am getting a bottoming out/popping sound out of the driver at moderate levels. I just had the amp replaced under warranty because it wouldn't turn on any longer, when it would turn on it put out a steady rhythmic kind of thumping/clicking sound out of the driver. Also it would kind of crackle when the auto on would turn click it on(still does I think). I also have a PB12-NSD/2 which seems to go a lot louder than the PB12-plus and doesn't make these sounds or any other weird sounds at all, ever. Is this common with the PB12-plus for it to protest/bottom out/pop? I am not sure if it is possible that the driver was/is bad and that is what damaged the original amplifier? I know the PB12-nsd/2 has 2 drivers but it just seems like the plus just doesn't do it for me. I am just wondering if I have had a bad subwoofer from the start and that is why it has never really impressed me all that much. I do not abuse my gear and do not generally play it at all that high of levels as I have kids and a wife who doesn't like it loud. Any thoughts on the popping sound? Thanks

I set mine to 31 hz with slope -6. I can't hear a difference.

It sounded awful, with an obvious step between the sound from the speakers and the sub - not localisation or obvious channel level differences, but just a clear lack of blending. Setting XOVER back to 80Hz made it sound better.

Since the only ill effect expected from upping the XOVER is increased localisation, I played around some more and discovered that the +2dB bump was the culprit and that MCACC had got it just right. A few more demo listens with 100Hz confirmed that it sounded great - not enormously better than 80Hz for those demo samples, but noticeably better.

Later I'll do a more thorough job with frequency sweeps, but for now I'm happy to have followed your advice. Thanks!

Hey Isdec,

Rooms are different, so my particular settings might not be ideal for you.

If U can...run a new FR sweep with your system in present configuration...MINUS the Room Gain Comp.

This will help you determine the best RGC freq to choose, and the slope (6 or 12) needed.

Edit: I think that HT enthusiasts, and Music hacks like myself have differing views on what"s correct....but a "Constant" in the dscussion is that FLAT-IS-FLAT where Room Response is concerned.

Tools like Room Gain Comp can be your best friend...AND maybe even keep a few DB of Amplifier Power in reserve....for when you REALLY need it. smile.gif

You're right that Room Correction may be useful, especially if there is no other form of EQing in the loop. In a small room, room gain can be surprisingly large, but it's not the same as room modes, which will create huge peaks. In my small room, I have a large 9dB peak at 45 Hz; at a friend's, he has two, at 35 and 45 Hz, but both are wide and merge into each other. The 35 Hz peak extend all the way to ~25 Hz, so using Room Correction could have tamed it a bit.

But Room Correction is really meant to tame the room gain that is mostly prevalent below 35 Hz and is not peaky. Maybe room gain can cause sub-35 Hz frequency to be boosted when using an Ultra that is otherwise flat (in an anechoic setting) down to 25 Hz and below (depending if it's an SB13 or PB/PC13). Since I'm using external EQing, this is dealt with the EQ anyway. Room gain simply helps lifting frequency after the roll-off.

Note that except for bass test tunes and perhaps some electronica like dubsteb, and also few notes in organ works, there isn't much content in music below 30 Hz, so for 2.1-ch music listening, you won't lose much using Room Correction.

That doesn't sound good at all. Was the popping sound there before you replaced the amp? Anyway you should contact SVS. Yes, it's possible that the driver is bad. If you're able to record a video (with sound) of what you're experiencing, I'm pretty sure SVS will advise you quickly. In my case, I got two PC12-Plus and one of them was DOA. I doubt this is your case but in mine the driver was stuck and produced very little output even at max amp gain. SVS had me test the driver using a 9V battery (I advise you to do the test only per SVS's instructions), and there was no perceivable movement from the driver, only clicking sounds (whereas it's supposed to move a full inch). My point is: even brand new a driver can be damaged. SVS's service is great so don't hesitate contacting them again to explain your problem.

Good call Neutro. We're emailing with this customer and have asked for a video of the artifact. It will help us determine if it's the amp or the driver and then we'll be able to better recommend the next step(s) to correct the problem.

I'm going to try it. My guess tho is that my family room where my setup is > 2500 cu ft and it opens up to the kitchen that's about 2200 cu ft so I probably won't need this on.

But I do agree that it's great having a sub with this flexibility.
post #10662 of 15693
Neutro,

I don't really recall hearing the popping sound ever with the original amp that has since been replaced. The old amplifier just gradually would not turn on all of the time and when it did it would emit kind of a clicking sound, rhythmically out of the driver. I don't turn my equipment up much but when the kids are out with the wife I tend to crank it up a bit, but I don't want to hear a popping/bottoming out sound out of my hardly used subwoofer. I kind of wonder if the two incidents are somehow related. I don't know how I could have damaged the subwoofer. Thanks for the help.
post #10663 of 15693
I just received an e-mail from SVS with this main message:

"When we introduced our Ultra Speakers last year, we asked you to give them a try and backed them with a 45-day, no hassle audition policy. That policy covered shipping both to you and back so there would be no risk. Many of you jumped right in and our 45-day audition has received great response. So much so, that you asked us to extend it to all our products, and that's exactly what we're doing.

Effective today, and exclusively for our followers, all SVS products are available with free shipping to you—and free shipping back in the event it's just not the right fit. No questions, no push, no hassle - we promise. That means 45-days to audition our products in your home with your gear and your settings, risk free. So go ahead, give us a listen."

So, for the folks on the fence.................what are you waiting for????

SVS is one of those companies that I recommend over and over again. Amazing products at a good price and some of the best customer service in the business. Ed Mullen is indispensible for support and questions and gives some of the best advice in subwoofer options, setup and use out there. This new no risk trial is just another reason I can't recommend them highly enough. I've owned and used SVS subs in my rooms for well over a decade now and I've never had a single complaint.
post #10665 of 15693
Neutro - Thank you for your advice, I have the PC 13 Ultra set at 16 hz and will put it at 20 hz and see what happens. It just seemed a bit more substantial in the bottom end but as you explained I most likely will get more out of the two subs at 20 hz. I admit to not spending much time with the Ultra at 20 hz. I will keep you posted on the results. The UMC 200 is set at 80 hz. Both subs are in a corner placement on either side of the front speakers and is the only positions I can have them in.

Well it looks like you're in good hands now and I hope this will get resolved fast and without much hassle for you. Maybe the new amp is the culprit then. I hope the driver was not damaged, but frankly, damaging it would have been heard loud I guess.

***

A side question, kind of related (speaking about subwoofer noises). I already wrote about that event: we were testing out my older SB12 at a friend's house and we demo'ed it using the Pulse server room scene, which is notoriously harsh on HT equipment since it has very strong sub-20 Hz content on all channels (go figure). Anyway, the crossover sent all of that to the sub of course. But at the volume we were listening at (a bit high), with the sub running, huh, a bit hot, we heard plenty of strange noises coming out of the driver. We got the volume lower but we had to go pretty low to get rid of the noise.

It sounded to me like harmonics (higher frequencies) so I guess the sub was badly distorting. I thought the limiter would prevent that but thinking about it, I figured that for some waveform, maybe the regular bass signal (say 80 Hz content) is sitting on top of a huge 15 Hz wave, and the limiter have no choice to flatten the peaks off the crest of those waves completely lest the driver hit xmax. So maybe it's totally normal. The SB12 seemed to work very well for other content afterwards. Still, I wonder what are the chances that we caused damage to the sub? Was this only limiter-induced distortion? Anybody got unwanted distortion with that scene (it's on many demo discs out there such as Jindrak's and Superleo's volume 2).

I tried with my current setup and I did get an awful lot of dirty noises... but they were all coming from my air duct and vents rattling and vibrating, not the subs.
post #10667 of 15693
That's what the Ultra drivers buy us. It's a beast of a driver and is darn near indestructible!

I have the PC13-Ultra, also. Tuning it to 20Hz will give you a higher SPL than tuning it to 16Hz. I have mine unplugged and running at 20Hz.

Unbeatable offer for a product like this. I'd wager that SVS doesn't get many Subs returned anyway. smile.gif

+1. I feel the same way. All of my SVS subs are fantastic and I would recommend them to anyone. I helped convice a friend to buy 2 of the new Ultra sealed models they are incredible.
post #10673 of 15693
Neutro,

I have just sent a couple videos off to Ed so hopefully they can get to the bottom of what is causing these strange noises from the driver. It happens when it hits a certain volume then as you said I have to turn it down a ways to get it to stop or get outside of that range where it emits the sounds. Hard sound to describe but definitely is coming from the driver. My NSD/2 has always been bulletproof since purchasing and when turned loud it seems to "compress" but never emits odd sounds. I kind of wish I had a second NSD/2 over this PB12-Plus at this point. Maybe I have had a bum PB12-Plus for 2 years now. I have always had the NSD/2 going and it seemed to always kind of over shadow the PB12-Plus so that is why I didn't notice it not performing as it should have. Not sure here.

Thanks again for the help.

Ed and the staff at svs think it is the amplifier causing the odd sound. They were extremely helpful and are sending a new pretested amp out to me right away. Great service as usual. Hope its the fix. Thanks guys.
post #10675 of 15693
I hope it is!

On my end I finally decided to use the MiniDSP to add a house curve to my otherwise flat EQ, in the simple form of a single low-pass shelf filter. The added ULF punch is really nice and I love how easy it is to tweak the settings, live, on the MiniDSP. Maybe I exaggerated a bit though but the SUVs sure show their presence now biggrin.gif
post #10676 of 15693
Tommy! Great News! If Ed says it's the Amp...IT'S THE AMP BRO!

Ed is never wrong with these things.

It makes me feel good to see SVSs " emergency response team" respond so effectively.

Just another reason I'm so happy I chose SVS.

There IS NO OTHER!!!

All the Best!!

If it were up to me? I'd bite the bullet, sell a Kid, or do whatever to get the matching pair! It's extra money, but there will NEVER be any lingering doubts or regrets about the decision. Don't let me spend your money, but in this case? The extra $$ is cheap insurance against any possible disappointment.

It's the ABSOLUTE right thing to do!

Duals Rule!

My suggestion? Talk to Ed.


Edit: Allow me to condition my responses with the comment that I have NO intention of being the typical "Fanboy", or some kind of "Shill" for SVS.

My thing is...SVS treated ME like I was the only customer they'd ever had. Nobody ever tried to "sell" me anything...and in fact? Ed himself has thrown a penalty flag on some potential purchases that simply would NOT have worked.

This is what I define as INTEGRITY.

My listening enjoyment is off the charts BECAUSE of SVS. I believe not only in the Product...but Also in the People who support those products.

Money Well Spent!

What is the "Trade in list"?

I'm planning on upgrading from my dual SB12NSDs to dual SB13Ultras using the "Bill of Rights"
