I think one of the leading factor in that case is that the driver is physically at a different position in the room. It's well known that if you take a front-firing sub and turn it around so that it...

Indeed -- if you look at the impulse response for the SB12-NSD, which is sealed of course and has a -3dB point at 220 Hz, it's roughly equivalent to the PB13-Ultra in 20 Hz mode:

Well, not sure I want to stir things further but here is more food for thought on that topic.

In a linear system (which a subwoofer is not, but strives to be), the frequency response is the...

Still, I think we kind of need a good spectrogram software dedicated to bass hunters for movies and music. I kind of started one on my free time but quickly got frustrated by the state of...

Sorry for the delay... if you get DTS Master Audio bitstreaming from the PS4 in some discs, I doubt there is any incompatibility with the receiver. I have no idea why the core DTS track is sent to...

Rather, I think every doubling of the distance reduce the output by half, i.e. 6 dB, so going from 2 m to 4 m removes 6 dB.



That site is exactly why I posted the question -- I was wondering...

Thanks a lot for having taken the time to dig that up. Very interesting.



Yeah deviation from linearity *is* compression right? So compression begins to be noticeable at 100 dB, 2m on their...

Concerning the grilles on the RC's... I find them super nice. Without them the speakers are very "in your face", perfect for demo nights with the guys, etc. With the grilles on, they look like black...

BTW Mega is indeed controversial because of its founder (infamous Kim Dotcom) but I think it's much less shady that many, many sites out there. I have no idea why they use that scheme for saving...

As retro said, contact SVS & your dealer first (assuming you did double-check your AVR and sub settings like trim level, gain, etc.). I'm pretty sure they will instruct you to remove the amp to check...

I missed the original poster. Well as always I'm with you bear. It has to be noted that you can't expect low THD below port tune in a ported sub, and in fact from experience, you can't expect much of...

On one hand it looks pretty much the same as the PB-2000 sound-wise. A few people on this thread got one, and I've not seen negative comments regarding the new layout anywhere.

As you can see on the first post, there is now a Vol. 3, but it's no longer a demo disc. Rather, it's a demo folder containing the .m2ts files themselves, which can be played by various software &...

Interesting, I'll look into that -- but still, I think it is a bit too general a statement. I mean technically, if I'm getting, say, 93 dB SPL without compressing 12 ft away from my aluminum dome...

Well I can't say I have exceptionally good ears so I can't really say if I get compression or not in the highs and mids. But the sound seems exceptionally clear to me. It's just that crashes (e.g....

That being said, two PB-2000s in a 1600-cu ft room is already a lot. One question that hasn't been asked is, do you know if you're reaching the...

The PS3 cannot play the .m2ts files (or at least, not all of them, might depend on the codec/format), unless of course they're on a BD (go figure). You'd need to transcode as you discovered.
