It will overhang by 1/2" on each side. That will be plenty stable.

Thanks ransac

Hi everyone. I have a question. Is it possible to bottom a 20-39PC+ with the following setup. All speakers calibrated even, not running sub hot, receiver set to -16, LFE@00dB, sub gain @11. Watched The Incredible Hulk last night, and the last battle scene where the two combatants are dangling from the helicopter, and fall, I hear a loud knock once. I replayed it and i heard it again. This is in a 1750 cu. foot room. Should this be possible, and can a sub bottom a couple of times without damaging it?

Thanks for your input,
Sven

I have a SVS PB12-plus which is pretty much the same sub. My room is smaller than yours, everything is calibrated, I'm running the sub little hot.
I've bottomed it quite a few times now. Normally it's an amazing sub, but a couple of these new movies in the new sound formats is killing my SVS.
I've since turned it down a tad, I'm sure it hates me by now.
But yeah I've had it a year before I bottomed it, weird sound huh?
First time it happened I thought books had fallen off my shelf, but it was the sub. I haven't noticed anything different sounding since, but that is a good question of damage from bottoming. I wonder if the fuse would blow before damage occurred??
Anyone?

When I had the same sub, it bottomed on King Kong when the ship hits the rocks and on Harry Potter 2 when the dragon flapped his wings. It was a horrible sound. I upgraded to a +/2 and haven't had it bottom once.
How hard it bottoms will determine if damage will occur. Since SVS doesn't use a paper former, it has to bottom hard or often to cause damage, but I wouldn't want to press the issue.

My Living Room consists of a 52" Sony XBR5 and recently purchased Ascend Acoustic Sierra 1's Rt, Lt & Center. I have been reading and researching for a sub. Because of the furniture and limited floor space I had decided on a downward firing cylindrical sub and was close to ordering the yet to be released SVS PC- 12 plus. (Living Room Area 22’ x 14’ x 8’). I would love to be able to fit in a big box sub with a depth of 25" and a width of 20" but that would be impossible. The SVS cylinder has a diameter of 16 " and height of 40" a much smaller footprint. It would be used for HDTV via Comcast cable, Blu ray and music, equally divided.

I have repeatedly heard people speak about the tighter more articulate bass associated with sealed subs and I've seen the graphs that describe it. Can you please tell me, with your SVS sub, when playing music do you feel like something is missing? Do you say to yourself, "Oh this doesn't sound very good I can't discern the bass guitar (pipe organs) or the bass is just not in sync with the other instruments." Or is it something that an average listener playing music from their ipod, CD player or phono, whose input into the AVR is with analog RCA cables wouldn't notice. Do you find when listening to music the bass to be too “boomy?”

I don’t believe this is considered cross posting. The link below concerns my quandary regarding ported vs. non ported, specifically the new Ascend Rythhmic sub vs. SVS PC12-Plus but it contains the attachment to the room I’m discussing.

I would appreciate your thoughts on how your SVS subs, in general, perform when listening to music.

If any of you have specifically matched your SVS with the Ascend Acoustic Sierra 1’s I would love to hear your thoughts.

Thank you for your time, responses and suggestions

Just curious, what did this turn out to be? Cable or amp?

I am thinking about getting the SVS SB12-plus for our living room about 2300 cubic feet. I can not put anything large in that will mess up the aesthetics of the room, WAF. I notice not to many talk about this sub, and wanted to see if anybody has it and can tell me what they think.

It turned out to be a bad cable. I have not had any issues with the sub once I replaced the cable.

The SB12 is a sub with excellent sound quality which particularly excels with music. Due to it's size, it's deep bass capabilities are somewhat limited and therefor has the least deep bass output in the SVS line. It's a good choice if you must go small.

The previous rev of SVS subs got a bad rap for musicality. I never had a problem, but there were differences between them and some of the competing subs of that generation. The SVS seemed more bottom weighted. Over the last 2 years, they improved the NSD line, brought out the Ultra13 and now the Plus is getting a facelift. No one's heard it yet, but talking to Stephen Ponte, it's going to feature a more overdamped sound, "sealed like", with great extention and power. What you're likely to notice is the SQ improvement vs output (which is limited by the same physical dimenions, driver size and power). So what you're worried about shouldn't be a problem. There weren't any phase timing problems with the earlier Plus subs. They weren't sloppy or slow. The new sub should be quite a musical improvement as well. Hope this helps.

I've read the reviews and the specs on the SVS SB12-plus and it sounds like a good sub, but I would like to get some first hand knowledge from some owners on what they think. I will not be cranking the volume up to max levels, mostly will be used for Blu-Ray HD sound, Directv HD, and occasional cds, at moderate levels.

What more can I tell you? I've had a pair from when they first came out over two years ago. If there are any more details I can help you with, ask away.

What do you think of your PB12-NSD overall? I don't see a lot of discussion on the PB12. I got mine last week but I had a couple issues unfortunately. My new amp will be here tomorrow so I am hoping I will be very happy with it. Not so much so far but these things happen...

You say you have a pair of SB12-plus, I would like to know how just one works. I do not plan on buying a pair.

The reason for the pair is that the room they are in is 6000+ cu.ft. and is open to the rest of the house. In your 2300 cu.ft., a single SB12 will do a good job up a decent volume. What it will not do is shake your foundation with killer deep bass. When played within is range of clean output, it's a great sounding sub. If you wish to play movies at very loud, so-called reference levels, the SB12 will not cut it.

I'd suggest trying corner-loading for a single SB12.

Thank you so much for taking the time to respond to my inquiry. You have relieved me of a lot of anxiety I was having about ordering one before it underwent critical review.

I'm looking for a sub(s) for my HT. Open for all suggestions at this point.

Room size is roughly 13x24x9.

Been looking at the 20-39PCI and getting 2 or perhaps getting one of the new PC12-Plus or older 20-39Plus.

Does anyone have a similar size room with either of these for suggestions?

Thanks.


Also, is anyone near Atlanta willing to let me listen to one of their setups? Of any SVS sub.

I tried the 20-39PC+ in a wide open, 8800cf space. It was almost there and gave some good punch, but the room was just too big. Traded it in on the +/2. Now I'm good. I think I would spend the $100 and preorder the new PC+. The motor is beefier and looks to be based on the Ultra design.

Anbody experience problems with their amp on the SVS 20-39 PC+. I had it running fine for about 10 minutes through Iron Man, decided to move it to another corner to see the sound difference. Now it won't power back on. When you turn off the switch, you can hear a very faint whine, but when you turn it on, it is silent and no green light.

SVS told me to unlpug it and turn it off for an hour, possibly a capacitor?

Anybody experience the same issue?

In my @2,000^3 room my two Pb10 for me weren't quite enough for HT. Your 2,808^3 room one 20-39 Pci maybe good for your needs but for me I would want two. 2 Pb10 is suppose to have the same output as one old plus. So if I were you I would get the new Pc12 plus . If it weren't enough get another later. But if you have a tighter budget and you want mainly a ht experience vs music the 20-39 Pci two of those probably would be the best deal. Hard to say what you like. One maybe enough for you??

for normal people, i think a PB10 in a sealed 2k room should be sufficient

So is this for "Normal People".

I have one. I have had it for about 8 months. First of all, I love it, , no exaggeration, but bear in mind, this is my first sub. It is my favorite part of my audio equipment, no doubt. The thing that brought my HT experience to a level I never had experienced...I am just glad I didn't wait any longer. I might have never gotten a sub, if it wasn't for my new plasma tv, which had speakers that rattled. So I decided to do the HT thing, including getting a sub for the first time. Just wow. It rumbles, grumbles, slams, plays music I do not regret it that is for sure. I listen to movies around -5 to -8 usually, and that gives me plenty of sound. If you listen at a lower level, it is probably fine too. All that said, do not be concerned if you see other posts by me in other threads about getting an Ultra-13. It is something I have considered just because I am convinced, for me, I will have fun with it, that it should be a step up, deeper extension etc. But if for some reason I cannot get it, afford it, whatever, I would happily enjoy the SB-12plus that I already have. HT is cool for me right now, with what I got, my movie/tv/music experience is better than ever.

Don't think I'm normal!

Want to have the most bang for the buck....I"m leaning towards getting a PB13 now. Maybe another later.

Still thinking about the PB12-plus too.

if you are even thinking about the PB13 - i recommend that you save money to get what you really want ... you'll upgrade anyway, might as well spend it right the first time.

+1. In the past year and a half I've gone from a Velodyne VX-10 to an Infinity PS212 to a single SVS PB10-NSD, then added a second PB10-NSD, and finally sold those and got an Epik Castle. Take it from me - it's much cheaper to do it right the first time . And jagerbombster, I'm not normal either. My Castle is in a 900 cubic foot sealed room.

Hi guys. I posted a little while ago when I experienced what I believed to be a driver bottoming out on my SVS B4+. Link below of review of the sub:

http://www.hometheaterhifi.com/volum...er-9-2003.html

I'm running a Quest QA-3000 pro-amp (Australian Made) which is bridged to 2100watts. As a poster said above these new Audio tracks are extremely high in the bass department. I have my sub calibrated below 75db (approx 70db) at reference being 0 on the receiver (Onkyo 805 using as pre-pro). I never get anywhere near reference normally around -14 on the volume when listening to True-HD or DTS-HD MA. I hear a metal ding sound during a bass heavy moment ie Ironman breaking the sound barrier for the first time and now in the new Hulk movie where his fighting the Abomination has him on the ground and punches him I hear it again. The peak limiter light on the amp flashes briefy as well. I mean could the amp really be drawing 2100watts to power these scenes? Going by that review of the B4+ it should be capable of handling these bass bits. There are 4 port holes in this sub and at the moment I have 2 blocked. I'm getting a bit frustrated and disappointed that I'm finding the limits of this sub. The reason I went all out and spent the money which was alot was so I had a sub that could handle anything that was thrown at it and I'm not running this hot at all. I read reviews of other subs like the Fathom series handling these scenes no problem as well as the PB13Ultra. I mean this sub of mine has 4 12" drivers but I simply cannot see where the other 2 are in relation to the 2 which are facing outwards (silver cone on both ends of the sub). I have e-mailed SVS but no one has photos or a decent diagram showing the outlay of the B4+. I really need anwsers before I either buy some new 12" drivers from a local seller here in Australia being Deep HZ, or simply turn down the sub more and live with it. I'm hoping someone on this forum has this subwoofer and can enlighten me on some of the questions and problems I'm experiencing. Thanks in advance.

simon, i am totally not familiar with that subwoofer ... but you should get a hold of the SVS big guns like Ed M, Ron S about the B4+

also, maybe a subsonic filter would do you good (it's basically a highpass filter, that lets you UP the volume on the frequencies that matter and stop the low frequencies from bottoming your sub)

there are many ways to get a highpass filter:
-Behringer units like the DCX models
-Velodyne SMS-1
-FMODs

Thanks for the reply Ribbit. I sent SVS a few e-mails explaining my problem and Ron did get involved but even he didn't have a detailed pic or production photos of the Sub. I got a basic sketch from them showing the driver layout but it was hard to see. From the drawing it showed the 2nd lot of drivers directly behind the ones that have the cones showing on both ends of the sub. I really had a close look inside the centre enclosure and cannot see how there could be a driver behind the other ones. When you look at the driver on one of the ends it's end goes into the centre of the sub (centre enclosure) refer to the link that users the term centre enclosure to know what I mean. I was told that there are definatly 4 drivers but I cannot see where the end of the drivers are other than the 2 that are visible from both ends of the sub. God it gets very confusing and it's hard to explain it to people without actually looking at one in the flesh. I need someone at SVS to find a pic or draw a proper diagram to show me the configuration. If indeed I need to replace a driver I need to know how to access it. I mean I'm hoping whoever designed had that in mind in case of a driver failure. Thanks again for your suggestions will have a read about them.
