Thanks, Ed! Does the same thing hold true for the difference between the PB12 (or PC) NSD and the newer ported 2000 models? This kind of question comes up fairly frequently on various threads, and I had it wrong.

They are close at 16/20 Hz (mostly port and box size), and above that (25-80 Hz) the PB/PC-2000 has about +3 dB over the NSD.

The SB12-NSD isn't quite the bargain it was just 3 days ago. Apparently Huppins/Onecall realized they are the only internet seller that still has them in stock, and brought the price up $50. I would suspect that means they are low stock, and selling reasonably well, probably partially due to all the recommendations on AVS.

Just wanted to jump in with a brief subjective PB 2000 comment...

We periodically encounter posts requesting comparisons/opinions between various ID subs within the PB-2000's value range. Databass, test report, and various anecdotal GTG information will surface supporting the prowess of one sub over the other. Although the numbers do tell a story, they do not tell how a sub sounds. And most of us understand that a room's physical and acoustic properties, sub location(s), and proper set up all influence a sub's performance. Having said this and as a previous owner of dual PB-2000's, I still hold them in high regard relative to FR and in particular sound signature and sound quality in medium sized and even some large rooms for both movies and music. To put this in perspective, I've auditioned in my home comparable and larger products from PSA and JTR. Also, as you're both aware, I've recently owned PB-13 Ultras and currently own the PB-16's. Some subs may/will outperform the PB-2000's in terms of output. However, IMO few have better sound quality. YMMV

Ed,

When you get a chance, would you please explain the Room Gain Compensation feature of the PB16? The Owner's Manual doesn't provide much information on what it actually does, or how to employ it. Does it boost the selected frequency by some fixed amount, or does it cut the selected frequency? It sounds more like attenuation to me, but I don't remember seeing an explanation of it. I am also not clear on what the RGC slope of 6db or 12db does in this context.

Thanks for the help!

Regards,
Mike

Not meaning to step on Ed's toes but thought I'd throw my 2c in as I had one of each (PB12-NSD & PB-2000) and ran them together for several months. Whilst the PB-2000 definitely had a bit more impact in the mid-bass range , I noticed the difference waaaayyy more down low. In my room the NSD had very little output under 17-18hz. The PB-2000 on the other hand still has noticeable output around the 15hz range . The Edge of Tomorrow intro would show this off very easily, with the NSD only playing the first 3 tones (30,25,20) and only some minimal cone movement on the 15hz tone. The PB-2000 shakes the house on the 15hz tone. The WWZ hand grenade scene is another where the NSD would drop off about half way through the sweep, whereas the PB-2000 does this scene very well.

I concur...had the same experience with the same scenes. Not only does the PB-2000's response go that low but it sounds good doing it. Other subs seem to "rumble" while the PB-2000 for lack of better descriptors plays...tight, smooth, clean, and clear.

I recently relocated an old rarely used PB10-NSD to my theater room to see what would happen. I've got it behind my MLP for nearfield impact. Wow. Aside from throwing my back out lifting it improperly, I'm starting to get used to it. I actually had to turn the gain down a little bit as it was a little overwhelming and threw off the balance in the room.

I'm still playing with it, but so far...yeah. PB10 + 2x PB-2000 is pretty awesome so far. That's a lot of bass for my little theater.

SALE OR TRADE my SVS PC-2000: Hi SVS people - I'm in the NYC area and would love to trade my like new PC-2000 for a PB-2000 on the off chance that fits anyone's needs. My place is just too small for the PC-2000, so going back to a cube works for us. If anyone's interested in just buying it, I'll do $675.

P.S. My apologies if I've posted this in the wrong place - kind of new here.

I found this digging around their site.


"ROOM GAIN COMPENSATION
This menu option compensates for excessive amounts of ‘room gain’ (a rising low-end bass response most common in smaller listening rooms). Excessive room gain can create a bloated or bottom-heavy sound from the subwoofer.

The acoustic roll-of slope of the SB13-Ultra is designed to complement available room gain in most listening spaces, so this menu control is rarely used with the SB13-Ultra. It is more commonly used with the SVS variable tune models (PB12-Plus, PC12-Plus, PB13-Ultra, PC13-Ultra).

The room gain compensation control is adjustable for frequency (40 Hz, 31.5 Hz, 25 Hz) and slope (6 dB/octave and 12 dB/octave). When enabled, this control will reduce the output of the subwoofer below the selected frequency. The steeper the selected slope, the more aggressive the effect. The factory default setting is Disabled.

AVR: If the A/V receiver set-up function equalizes the subwoofer channel (such as Audyssey MultEQ XT or XT32), the room gain compensation control is not required. If the A/V receiver set-up function does not equalize the subwoofer channel, the room gain compensation may be beneficial to reduce excessive amounts of low-frequency energy in smaller listening rooms to help restore a more balanced presentation.

2-CH: If excessive amounts of low-frequency energy are present in smaller listening spaces and the presentation seems bloated or bottom-heavy, the room gain compensation may be beneficial to help restore a more balanced sound."

Dunno if that answers your question, but I'm guessing it's more descriptive than the manual.

Thank you very much! That's exactly the kind of description I was looking for. I assumed that the RGC attenuated only, rather than boosting, but the question came up in another thread, and I wanted to be sure.

The RGC is essentially an adjustable high pass filter. It attenuates output below the selected frequency. The rate of attenuation is defined by the slope (6 dB/octave or 12 dB/octave).
