AIUI the PB12 and PC12 NSD versions are sonically identical. It is only the form factor that is different.

Probably but that is a big room. I use my pair of PC12-NSDs in a room half that size and they sound wonderful. You may just need a bit more in that room of yours - maybe others with larger rooms and PC12-NSDs might care to comment (Fastslappy - you there?). Or fire off an email to SVS - they usually respond within an hour or two, even on a weekend, and are very helpful.

No. The driver is at the bottom and faces the floor - well it faces the plinth that the sub stands on but it is downward firing. The top of the sub is the port opening. It's not really going to make any difference to the neighbours though - if it shakes the room, it shakes the room

Can't comment on that, sorry. Other than to say a good sub is a good sub regardless of what it is used with.

EDIT: you might want to have a look at the Official SVS Owner's Thread where people are discussing right now the merits of different SVS subs in different sized rooms.

I guess I better toss my hat in as another satisfied PC12-NSD owner. Got mine as an early Christmas gift this past year. Have it corner loaded about 9 feet from the main listening position in a ~2500 cubic foot room with Klipsch RF-5 fronts, RC-3II center, and RF-15 rears, with an Onkyo TX-SR707 (with Audyssey MultEQ) as the brains behind the operation.

I have to admit to being duly impressed with the depth and clean output of this thing, even compared with its predecessor in my system, a PB10-NSD. First movie I watched with it was Green Zone; suffice it to say, the opening scene depicting the Shock and Awe campaign in Iraq shocked and awed me!

My Home Theater/Media Room is 13' x 26' so the cubic feet of our rooms are fairly close in size (assuming your ceiling is 8' high). I placed my PC12 in the corner near my Left Front Speaker and after using my Pioneer's MCACC calibration system the PC12 literally blows me away. I should mention that I don't use the whole length of my room for home theater (I have a computer and office equipment at the very back of the room), but when I'm watching a Blu-ray with plenty of LFE material I can stand towards the back of the room and still feel the *punch* and the *rumble*. Last night I watched Master and Commander and in the first scene, when the cannons start going off, the sound was awesome beyond belief. I NEVER experienced anything close to this with my sealed Velodyne sub (with a 10" woofer and a very small 80 watts RMS amp).

EDIT: I just caught the part of your post where you mentioned the "attached kitchen." That would make your room considerably larger than mine and so I guess I'm not qualified to compare our two set ups. If not for the kitchen, our rooms would be comparable (in cubic feet). I would highly suggest calling SVS to ask them what they suggest. They are truly experts in this field and will steer you in the right direction.

Hey Everyone - Looking for some final advice regarding my sub setup.

I got the SVS PC12-NSD yesterday and man, it's huge. I was expecting this monster bass performance. Instead, it sounds a lot like my old Logitech. I can't really figure out what's going wrong here. It's in a terrible spot, yes. But I figured the sheer volume itself could compensate for that.

It's located to the left of the front left speaker, kind of life in the diagram below, only swapped with the left RC-70.


I setup everything correctly. Gain is at 1/3, crossover disabled, phase 0.

Ran Audessey, and it rated the sub at -.5. Ok, perfect I thought.

I ran a few bass tests off of YouTube and it sounded brutally awesome. The problem is with movies and regular cable TV. Most of the bass feels like it's just rattling the floor. If I pick my feet up off the ground, I feel like there's significantly less bass.

My room is 21x17x9. I know it shouldn't have THAT hard of a time filling that space. Hell, my old Logitech did it fine. Surely an 800 dollar sub could too?

Anyway, I followed the advice of the many helpful people contributing to this thread and others:

LPF for LFE: 120hz
RC-70s: 60hz
RC-10s: 80hz
RC-LCR: 80hz

If I turn the bass level up manually to +2.5 dB (so it's 3+dB extra), it provides a nice punch I would have expected. I watched Casino Royale last night and felt the +3dB was required. But, is it necessary?

Barely any bass comes out for music. I'm not sure how to use 2.1 on this receiver...I've tried everything. I ran some music in multi channel stereo and it sounded alright, but certainly not what I was expecting for 800 bucks. Anyone have any advice?

Additional thought: Should I just pump the gain until my hearts content? I mean...the amp AND sub are covered for 5 years... Just a thought.

I got it yesterday so I'd like to take advantage of their liberal return policy if I really have to. When I was watching Casino Royale I caught myself constantly turning the volume down because the highs and mids were too much, but I was turned it up to hear the bass punch. Ah, first world problems. Any advice anyone?

If Audyssey set the sub to -5 with the sub's local gain at 1/3, then it's probably because Audyssey got a huge bass response at the main listening position. However, there are lots of non-MLPs where you will get much less bass impact in this room. After all, you've placed your sub in the middle of the room.

Unless you have a defective unit, your PC12 absolutely crushes your Logitech... no basis for serious comparison. I think that you have a placement or Audyssey measurement problem.

P-Nation,

I got a PC12NSD about 2 months ago (from an 8" energy), and went through the same thing. I ran Audyssey, put in a good BR, and watched with my wife. After the movie, we neither one could tell much difference. I knew it should not be that way. My room is about 4500^3.

No matter how many different Audyssey re-runs I did, the MLP just did not have the bass i was expecting. I downloaded REW and did some measurements at my MLP...and there were some very large nulls there.

After re-running audyssey, changing settings, etc...here is what has help me...YMMV though.

1) I was very limited on sub locations, to I bit the bullet and bought a second sub (pb12nsd). That REALLY evened out the bass in all seats, and eliminated the nulls at the MLP. I realize that might not work for all situations though. While the sound was much more even, I still did not think it was enough...which is #2 below.

2) Even with 2 subs and even bass in all seats, it still did not seem like enough. I think this gets to the reference level set by Audyssey and the preference level my family has. I still run the sub channel 3-5db hot. Not sure if that is really good or not, but in my 4500^3 room...that is what sounds best to us. We don't listen at extreme volumes, so I am assuming this is ok to do..plus the red limiter light on the back never comes on.

3) I think even with all the above, there is a difference between these "flat" types of bass responses compared to "boomy" subs. I think I was used to boomy and it has taken awhile to appreciate the quality of the sound with these subs.

Just some thoughts from my experience.

Actually, Audessey set it to - . 5.

I can see how you could confuse it with -5

Thanks for the lengthy and articulate post, I appreciate it.

1) I would really prefer to not purchase a second sub. The PC12-NSD is pretty huge and given I have such limited placement options I'm not sure where I'd place the second. I was humoring the thought of placing the PC12 to the right of the couch in front of the TV. However I would need one of those wireless sub adapters.... eeeehhhhh.

2) It seems most people run their subs hot. It's funny, with what Audessey set it at... the bass will 'pop' in during movies, but during mid-bass scenes I won't hear it at all. I guess it's how it should sound - I was just expecting more presence.

3) This is totally a possibility. I'm not looking for insanely high SPL bass, though. Just a more subversive sound. It's hard to explain.



Here's a crappy iPhone shot of the set-up I took last night in case I needed to bring it to the forums. You can see where the sub is. Awful spot, I know, but that wall the TV is on is where the cable comes out of and I'm in an apartment.

You're getting solid advice from gibsonpa above.

Your AVR bass management settings look fine.

Experiment with subwoofer placement to the extent possible - it looks like you might have several potential spots to try. You might find a different location which yields considerably better results - if so, make sure to re-run Audyssey to build a new EQ file. Regardless, with a single subwoofer in the room, you're going to fall victim to room acoustics and associated nulls to at least some extent.

The Audyssey sub channel level setting might be the most accurate from a level-match standpoint, but some enthusiasts simply want more and end-up running the subwoofer channel hotter. If you run the sub hotter, keep the sub channel level in the AVR down around -3 and then turn-up the gain at the subwoofer. This is preferable to running a really high AVR sub level.

Running the sub hot is fine and you won't hurt the subwoofer. Keep an eye on the limiter light, though. It's OK for it to flash briefly on loud peaks, but if it stays lit for longer periods of time and/or is lit very often, you are starting to compress dynamics and I would consider a PC-Plus (or duals) at that point. You won't hurt the subwoofer, but compressed dynamic range on bassy effects does tend to rob the presentation of excitement and realism.

Thanks for the wise words Ed! We spoke briefly a month or two ago when I was considering a B-Stock PC12-NSD. I ended up buying new, though.

I'll try adjusting the sub's gain setting and leaving the AVR's sub channel at it's Audessey calibrated setting of -.5. I'll report back with more information after I play around later tonight.

p-nation, I have a very similar arrangment except I am using a pb12 instead of a pc12.

Did you set all of the speakers to small in the Audyssey settings? I believe this is recommended as per the Audyssey thread.

Yes, all set to small. Otherwise it wouldn't have let me adjust the crossover settings. Thanks though!

Guaranteed this is strictly a placement isssue. Find a corner to put the sub in off possible. That should be the first try....mine shakes ybe neighbors house. Lol.

You could always try the crawl method to find good spot for the sub. Keep us posted.

You will have to move the sub off the wall in the photo. There is no way a single sub in a location like that will sound good. I recommend just inside the corner to the right or left rear of your couch. 3 to 4 foot in would be nice.
What would really be nice, is to rotate the room 180 degrees, putting your couch where the tv is now. that would make a world of difference in the sub, mains, surrounds. You would be able to spread out the mains like they should be. Your sound field would be so much nicer. You would think you had purchased a totally new system. Details would really pop more.
By the way you have nice looking mains. What brand?

Missed the line about the cable location. You have wireless and wired options.
If you flip the room 180, you can run the coaxial under the carpet going under the couch to the side and on to the tv. Just a thought.

In the diagram I hastily made I forgot to adjust the right side. The couch on the wall is a good 12 feet from the adjacent wall. So if it was in the right corner, it'd be like 10 feet from the MPL.

And thanks! They're Energy RC-70s with an RC-LCR center.

Would a wireless option suffice? I'd really rather not mess with the zen of the room at the moment, I really like the setup, despite lack of subwoofer placement options.

I get ya.

I was referring to a wireless option for the cable to tv situation on the 180 spin. As far as a wireless option for the sub signal, I would assume a wireless av transmitter receiver would suffice, but I have not tried this myself.
These look promising...

p-nation,

Someone can correct me if I am wrong, but I think the point Ed was making was not to adjust the sub gain "after" audyssey...but rather adjust your sub's gain so a re-calibration of audyssey puts the AVR trim a little more in the negative territory...like -5 to -3. That way, if you decide to run a little hot and bump the AVR trim up a few db...your AVR is still in the negative.

EDIT: After re-reading Ed's response...maybe he was saying to up the sub gain after an Audyssey calibration.

Based on my research (mostly posts from Ed over the years )...the new sledge amps work best with the AVR trim a little(?) negative (ie higher sub gain and lower AVR trim)...they work together.

In other words, you are trying to avoid Audyssey setting your trim to -1...they you bump it up 3 db...and end up with an AVR trim of +2...which is not ideal.

Does that help? I am sure someone will correct me if I am off base.

That way, if you decide to run a little hot and bump the AVR trim up a few db...your AVR is still in the negative.

EDIT: After re-reading Ed's response...maybe he was saying to up the sub gain after an Audyssey calibration.

Based on my research (mostly posts from Ed over the years )...the new sledge amps work best with the AVR trim a little(?) negative (ie higher sub gain and lower AVR trim)...they work together.

In other words, you are trying to avoid Audyssey setting your trim to -1...they you bump it up 3 db...and end up with an AVR trim of +2...which is not ideal.

Does that help? I am sure someone will correct me if I am off base.


I think you are right.
I have 2 PB13s with the sledge and I run them hotter and the AVR "cooler", lower. It seems to help most at higher volumes. The signal is being distorted that much more at higher volume with the AVR trim set higher.
I think for easy of use the AVR trim is easier for most. One can adjust on the fly, so to speak.

Ah - So you're saying to calibrate the sub with the dial at around 10 o'clock(for example... AVR adjusts sub level to -4(let's just say)... and then turn the dial to 1 o'clock for desired slamming effects.

Yes, exactly. A general rule when level matching the subs and the speaker channels is to run the gain hotter at the subs and the AVR sub trim level cooler.

That keeps the AVR sub signal clean and allows upward adjustability to run the sub hotter if needed.

Ed,

Thanks for your recommendation! I re-calibrated with the gain lower. Audyssey set the sub at -3.0 at the AVR. I then gave the dial a nice turn to the right... maybe to 1 o'clock (from around 10 o'clock) and WOW! A smile plastered onto my face. Those are the results I was looking for.

I can't imagine how much better it will sound with proper placement, but it's certainly meeting my expectations now. And after running some really high SPL bass tests, the limiter didn't blink even once. I think I'm all set for now.

P.S. Thanks everyone for your advice.

Thanks!... I actually noticed the limiter light was coming on quite a bit, though. During a movie like Inception, at least every 30 seconds or so.

I'm going to experiment a bit more with placement. Judging by the diagram I uploaded a few posts ago, would to the left of the couch against the wall be a good choice? Or perhaps to the immediate right?

Silly question but can this sub be laid on the ground? It ain't passing waf right now as she thinks I put in a sewer line in the house

No subwoofer I've heard has been able to produce the bass I've experienced in the Corps!

Must..stop...buying...every bluray release...

The limiter flashing occasionally on bass peaks is fine. If it was staying lit for a few seconds and/or flashing very frequently, then I would recommend lowering the gain a bit, reducing the master volume, or stepping up to duals.

I would try both locations; room acoustics can be hard to predict. While corner placement does excite all room modes, unless you have Audyssey to EQ the sub channel and smooth out the peaks, it's not always the best sounding placement choice. The PC12 is so easy to move around that it's short work to try all available locations in the room.

Yes, the PC series can be run horizontally with no problems. Just make sure the amp plate and power cord/sub cable are protected from roll-over. Many owners who run horizontal build a low-profile cradle for the PC to hold it steady.

has anyone with concrete floor had issues with the sub rattling off the floor. for example, the cafe scene in inception. it rattles so much that it shifts across the floor. +1 for the great bass, but it shouldn't do that right?

For concrete floors, installing a set of taller 3M half-round rubber bump-ons usually fixes the issue. Send us a note at custservice@svsound.com and we'll send you out a set at N/C.

Also, a small piece of carpeting under the subwoofer, or an isolation pad like the Auralex SubDude (or similar product) will also work.
