Thanks for the compliment! You know, I didn't really give it much thought when I placed them there... it was more for aesthetics I suppose. Maybe i'll move them...

Steve, nice setup. But why the TV so high on the wall? Any particular reason?

Update on the broken phono plug problem:

Turns out my GF has an otoscope, which happens to be ideal to look into very tight spots tongue.gif The situation is superbly inextricable here. The tip of the 1/4" phono plug, along with the plastic ring that comes just before it -- are in the bottom of the input socket, past the flexible metal retainer, in awkward positions. Removing the cover of the BFD I could insert a thin mini-screwdriver in the back of the input socket and make them move but I can't get enough leverage to push them out past the flexible metal bit. Well I can use the second input/output for now...

Update on the FR problem:

I managed to take a few FR measurements using REW tonight. eek.gif It's all over the place lol. I tried taking 3 measurements across the couch. The one in dead center is the worst, with two gigantic nulls. The good news is that it's not really a seating position (it's a 2-seat couch and the measurement was right in the middle). This happens to be the exact center of the room in the two axes so no wonder there are nulls there. The situation is slightly better on the right and left positions but there's still peaks and valleys (and, surprisingly, huge nulls above my crossover frequency frown.gif ). The peaks and valleys are not exactly the same on each side and it appears REW cannot average measurements, so I tried EQing for the "most likely" seating position. REW did relatively well I think, except that one PEQ used to tame a peak on one side created a big dip on the other side.

The overall result is not bad for a first try and I like what I hear. But during the course of the exercise I noticed two things:
  1. I think I'll really benefit from the second sub biggrin.gif No joking -- it should really help with that kind of problems. I can't wait now.
  2. The current sub location (which I used for the first time) provides good bass along one wall but very little at the main seating locations. I think it's simply the worse location I tried yet for a sub in my living room. I'll see how much time I'll have to wait for the second sub, but maybe I'll try putting the current sub where my SB12 was.

As far as extension goes... There's a peak at 17-18 Hz which is probably due to the sub's tuning, and which BFD cannot really tame because it is limited to 20 Hz. That peak is actually the peak response after EQing the sub. It drops amazingly fast below that though -- because of the ported alignment however: I can see the high-pass filter effect which doubles the slope of the decay, but even lower. Technically for the SPL level to be back to the main's level you have to go down to about 13 Hz; high-pass filter slope becomes apparent below 12 Hz. So extension seems great actually. With duals this should be solid. I'm tempted to try sealed tuning just for kicks.

EDIT: at FR measurement levels, no, I could not actually perceive anything below perhaps 20-25 Hz.

I'm not posting any FR result yet because it still looks ugly and it's temporary. Next step is actually listening to something else than frequency sweeps, and probably try another location for the working sub. Also, packing the problem sub and hope that SBA still has some PC12-Pluses in stock.

The closed tuning will most likely tame the 17Hz peak and extend the low end while loosing some dB max SPL. But with dual setup max SPL would not be an issue for you biggrin.gif

Can you give a sketch of your room with dimensions and furniture positions ?

No reason specifically, but some mitigating factors/thoughts on the matter are:

1. It appears a bit higher than it really actually is since the ceiling is only seven feet. The midpoint of the mounting bracket is at the 5 foot mark.

2. The room was remodeled in the not too distant past, and the section where the mounting bracket is was reinforced (ie it's not just drilled into a single stud) for good measure. I like the thought that I could probably hang from the mount and it would still hold, so I'm not itching to move it.

3. Going back to 2, it's difficult to estimate how high a TV should be in an empty room redface.gif I reckoned about 3 feet for the TV stand and another foot for the center speaker, plus the TV would hang down a bit from the midpoint of the mounting bracket, so 5 feet seemed OK at the time.

Edit: Doing a quick and dirty calc, with the assumptions of a 9 foot distance to the screen, and a three foot rise from my eye to the top of the screen (which ought to put the top of the screen above the six foot mark), I'm a bit under a 20 degree vertical viewing angle, which should be alright according to this:

It seems SVS ran into some production problems with their PB12-NSD grilles. Brian got the same problem as you apparently (go back a few pages and you'll see what it's all about). I guess you should contact SVS about this if indeed the grille cannot be installed correctly or falls off during usage.

I think you should. It seems, at least for the frequency range covered by the mains, reflections on the bare floor can cause all sorts of weird FR alterations. Then again if you don't notice anything abnormal it's not the end of the world. Our ears are not very sensitive to very sharp nulls for example.

Can you give a sketch of your room with dimensions and furniture positions ?

I did not express myself correctly -- after EQing there's no peak to speak of (the worst offender was at 55 Hz and got trounced by the BFD). Instead the response rises slightly as we go down in frequency due to room gain and the house curve programmed into the EQ. The max response is thus at 17.3 Hz, which is great. It drops fast below that but as I said, I should get reasonable output down to 15 Hz. I'll tell you if I notice it tongue.gif On Monday I ordered a bunch of blu-rays for about $10 each, including a few 5-stars and otherwise bassy movies (Hot Fuzz, Clash + Wrath of the Titans, The Raid: Redemption). I'm curious to test sealed mode mostly to see if 1) I can have real output much below what I was getting with the SB12 and 2) if I can actually notice it or tell if the Plus sounds different when sealed.

EDIT: forgot to add that once EQed, the Plus sounds *much better*. I listened to a bit of music -- not too loud alas -- this morning and was quite pleased. Also the "Amazing Life" THX trailer had *lots* of punch, whereas with the SB12 it strained a bit there in comparison.

As for a sketch of my living room, here it is:


The room is frustratingly narrow at under 11' and I can't really use the area between the main entrance and the kitchen area since it's dedicated to dropping grocery bags, giving space for my daughter to try and remove her winter coat, pants and boots, storing said garments, etc. BTW all furniture scaling is approximate. We settled on that arrangement because it allows seating on 3 sides, which we like more than our previous arrangement that had the 3-seat couch back to the bay window and the TV in front of it. It also reduces reflections from the window on the TV, and allows correct placement of surrounds. The tilted black rectangles are my fronts and surrounds -- yes, the mains are behind a couch and an armchair (but with the mids and tweeters above the armrests at least). This is suboptimal but there's no other solution unless we decide to shop for new furniture. Or a new house.

As you can see I don't have much space for big subs in there. The PC12-Plus are about the same size as the red clouds denoting possible positions. Position 1 was where my SB12 was placed when the TV was on the wall between the living room and kitchen area. It is a "known good" position that produces a relatively even bass, with strong intensity along the bay window and where the TV currently is, and atrocious bass in the entrance area. Also rattles a vent close by. Position 2 is where my SB12 was located as of last week. Corner loading boosts outputs, and creates surprisingly strong bass at the main listening position (2-seat couch). I thought by symmetry that would also apply to position 3, where my working cylinder currently is. But either the location doesn't have the same effect, or the woofer + ports arrangement creates a different distribution because strong bass is produced mainly along the 3-seat couch. Position 4 was never tried and would imply negotiating a new location for a utility table and a solution (shelf, probably) for placing the surround speaker there.

My first plan was using positions 1 and 3, but since position 2 had good bass at the listening position with the SB12, I feel I should test the Plus there too. If it works well, I wonder if using positions 1 and 2 would be acceptable since they would be on the same side of the room. Also it could reduce bass on the 3-seat couch. Distributing the subs across the room while still using position 2 would mean putting the other sub at position 4 with unknown consequences and with the most work involved (installing a shelf or mounting the speaker on the wall). Finally, positions 2-3 would reduce clutter in the rest of the living room and use maximally the front stage, but that would be a very tight fit I think.

As for other positions... that would be very difficult. The bookshelf behind position 1 will probably be moved elsewhere in the house, so that means I'd have some wiggle room around it. But we have to keep a passage from the entrance area to the couches so position 4 cannot be extended to the armchair. Position 3 has some wiggle room if I move a potted tree, but that would involve negotiations and possibly the death of said potted treed due to lack of sunlight if placed behind a black tower biggrin.gif

No, a rug doesn't affect the sub frequencies. It takes several inches of absorbing material to slightly reduce the amplitude of sub-80 Hz waves, and / or walls with mass (such as bricks).

A rug isn't going to make a lick of difference to bass frequencies unless you used 6"+ of roxul for padding. Which would be a very squishy rug.

As for mids/highs, removing the rug may be noticeable.

Need some help, hooked up the PB-12 nsd out of the box the way it was recomended and really not much bass...Unfortunately my reciever has no auto eq so I have to get out my SPL....Can anyone walk me thru on what I should do to get the right readings and adjustments....I did this years ago for my old sub and I had great low end...It's just been along time since....
Thanks for any help with this...My Reciever seems like it only ranges in the LFE from -12 to 0.

Put the gain on the sub between 10 and 12 o'clock. Put your test tones to where the mains are playing at 75db. Then test the sub level. You can measure it to 85db on the spl meter.

Adjust the avr level to get your sub calibrated. But it should be around 0 on the avr. Adjust the gain on your sub higher if the avr level is too far in the plus and lower the sub gain if it is too far in the negative on the avr. +/- 2 on the avr is optimal

Hello.

If I were you I would try to order a second PC13-Ultra, you will have the benefits of dual subwoofers and space enough power.
In my humble opinion, be a better choice than a Submersive.

It may be a good idea, but it makes sense Subwoofer capar two that are designed to give maximum explosion vented mode.

In any case take modo16hz can help flatten the area and create a response curve more smooth and only lose an average of 1.5 or 2 dbs.

I'm almost 100% sure that the 2 and 3 will be the ideal, generally is one of the best places where dual subwoofers behave.

These two positions are going to take my PC13 PB12 plus ultra and to optimize the response of my room.

It takes me arrives Plus, if all goes well, between Monday and Tuesday comes to my house ... As I said before, I promise pics of the new beast.

There are basic audio tones on all of the THX Optimizer titles(mostly DVD, some BD), listed here: http://www.thx.com/consumer/home-entertainment/thx-certified-releases/

Another option is to pick up a used copy of the Avia II DVD, which has a reasonably wide assortment of audio test tones, or the Disney WOW World of Wonder calibration discs.

Rick: don't panic biggrin.gif We'll walk you through a solution, I'm 100% sure. First thing first; you say your receiver has no sub EQ and the LFE level goes from -12 to 0 dB. Can you give us the model? I'm trying to see what kind of bass management it is capable of. If your LFE level is restricted to that range it's mainly to attenuate it in case it's too boomy; set it to 0 dB and make your adjustments through the sub itself.

As Brian said, begin with a gain between 10 and 12 o'clock. For now set the phase to 0, and the low-pass filter to "disabled" (all the way up). Using these settings, how is the sub sounding? Is something actually coming out of it? Or is it dead silent?

As for test tones, they're nice to adjust the settings to perfection but let's make it produce nice bass first. There are lots of places to get test tones -- one of the members here even created a great DVD image for that.

Hi Lecter. I'm already in 16 Hz tuning -- I did not even try maximum explosion vented mode yet (I guess this is 20 Hz tuning biggrin.gif ) -- please don't be offended Lecter, English is not my first language either, so I know how it is, I just think SVS should rename the boring-sounding "20 Hz mode" to MEVM.

Ok I have a Yamaha 5550 ...When I set it to 0db I have to put the sub gain at about 3/4 to get some low end, and it isn't anything that you would be impressed with. If I go off of my analog inputs from Blu Ray to dolby digital I do get more low end..I remember having this problem when I originally set up my old sub, but after making different adjustments. It was like all of a sudden someone flipped a switch and everything clicked and I heard what I was waiting for...Now I'm back waiting for that....

Hi

Next year, beginning five years of study to learn English perfectly. I have really wanted to learn English, so perfectly as I speak my language (Spanish).

Indeed 20hz mode is more muscular, is 1.5dB or stronger than 2db 16Hz mode, but you lose so much energy and sealing earthquake effect (A after all, is what it comes to getting these beasts SVS), I think that is your sell

The points before you comment, are ideal. It is also to measure and test issues, but generally there are universal rules on the placement of subwoofers. Referring to have one in the near field, it is my recommendation, since the LPF of LFE goes up to 120hz and this can be annoying and reachable for you. As a starting point, test point 2 and 3 (You will not regret it).

It just does not have the performance and quality that conveys the SVS PC13-Ultra.

According to the data there, the PB12-Plus sounds as refined as the PB13-Ultra DSP is just not as strong. Average is 3 dB less, but in comparison with the PB13-Ultra BASH 750w, the PB12-Plus DSP on the heels, I have understood that is practically comparable in terms of pure performance with the BASH 750.

I have been running a PB12 Plus (Bottom Firing) for about 6 weeks now and as much as I want to be, I have not been impressed. My room is 20x32 with an 8 foor ceiling. The sub is about 8' from the rear wall and connected to a Yamaha RX-A3010, calibrated using the same. I tweaked a little using the PEQ on the sub. Sub gain is as high as safely possible at 12 o"clock. I have a Velodyne HGS-12 in the front and even though it sounds pretty good, I expected more. It is an open floor plan, so the kitchen opens up, right off the same room (which I'm sure doesn't help). Is my room just too big or did I get a dud? Any advice?

Well 20x32x8 is already pushing 5000 cubic feet, and if that doesn't include the kitchen, then yes, that is a huge room. I'd expect a PB12+ to still give a decent accounting of itself (older model I take it since you mention its downfiring?), but depending on your expectations and judging by your impressions, you're going to need a lot more subwoofer to get the job done.

Edit: PS: if your subwoofer is 8' away from any walls, you might try corner loading for some additional output.

Not to worry. I decided to measure for kicks; the top of the TV screen is 10" from the ceiling, and eye height is about 40", so I am indeed OK on vertical viewing angle. Interestingly enough, the space between the center and the TV is only 14", so I'd guess the angle of the photo is somewhat deceiving as well. In any case, I can't say I've got any complaints with it in day to day use biggrin.gif

It was like all of a sudden someone flipped a switch and everything clicked and I heard what I was waiting for...Now I'm back waiting for that....

I'm browsing the manual for your Yammy right now. Be sure you're setting all your speakers to Small (SML) in the 1 SPEAKER SET menu, and the BASS item set to SWFR. This will send all LFE and all content below the crossover to the subwoofer. According that manual, your receiver can output a test tone for your subwoofer (after testing all other speakers -- note that if BASS is set to MAIN instead of SWFR, you will not hear the subwoofer test tone). It seems that on your receiver the sub cross-over is fixed at 90 Hz. For now I don't see other settings that could affect the sub signal on your receiver.

Except of course for the source. What are you listening to exactly?

Another thing to look at is the cable itself. You could try swapping it with another one; if it is damaged internally it could attenuate the signal.

Also sh!t happens. I just got a PC12-Plus with what looks like a stuck woofer. If your sub is defective SVS will take care of you. But we're not there yet.

Where are you going to study? UK? US? Canada? It's a great idea and I wish I had the courage to do that.

Indeed 20hz mode is more muscular, is 1.5dB or stronger than 2db 16Hz mode, but you lose so much energy and sealing earthquake effect (A after all, is what it comes to getting these beasts SVS),

Yeah looking at the FR graphs, I thought the 16 Hz tuning mode looked like a great compromise. The variable tuning is one of the reason I went with Pluses instead of NSDs...

since the LPF of LFE goes up to 120hz and this can be annoying and reachable for you.

You have a point. On some AVRs (Audyssey-equipped) the LFE channel has its own cross-over and you can redirect the upper frequencies to the mains; but that's not my case. Having symmetrically positioned subs will help with the mid-bass present in the LFE channel. I guess the real answer to that is to try both positions.

Is that mainly due to DSP and amp? or do you feel the driver you used is not up to par? It's certainly one of the most impressive sub I've ever seen tongue.gif

They do have very similar FR curves... Doesn't the Ultra do 10 Hz tuning? Maybe very close to sealed mode anyway.
