Hi,

What you guys think about the SVS PB12-NSD compared to Velodyne DPS-12 ?

(Velodyne DPS-12, DLS-4000R, VDR-12)

I got both Subwoofer tested, SVS PB12-NSD, Velodyne DPS-12

My Impressions between PB12-NSD and DPS-12

-SVS PB12-NSD, goes deeper, smoother, much clearer than the DPS-12

-Velodyne DPS-12, hits harder, got more impact, muddy sound, I can feel it got more Output than the PB12-NSD

I got the Velodyne DPS-12 about 2 years ago but sold it already,

I received my SVS PB12-NSD last week still adjusting, testing.

I like the PB12-NSD playing Music, it goes deep, cleaner, it's more accurate than the DPS-12.

For movies, I think the Velodyne DPS-12 got more

You did get some interesting responses to this same discussion you stated in avsforum.

I recently replaced my old Velodyne CT-120 with an SVS PB12 Plus - there is a dramatic difference, but comparing those two particular subs is hardly fair

The velodyne should have a jazz setting, i believe its similar to the dls series. That will give you the tighest and cleanest result. Anyways, i hope you keep the svs!

Hi,

Yes, I just needed more advices from experts in this forum,

Is your Velodyne CT-120 same as the DPS-12, DLS-4000R, VDR-12, in performance.

So, how was the Velodyne CT-120 compared to the SVS PB12-Plus, there is a dramatic difference?

What's the Pros, what's the Cons between the Velodyne and the SVS

-Velodyne CT-120

-SVS PB12-Plus

Can you see, hear a difference, a big upgrade from a Velodyne CT-120 to a SVS PB12-Plus?

Thank you

The Velodyne CT-120 is pretty low-end compared to any of the Velodyne subs you have mentioned.

The SVS PB12 Plus has a 525W amp and goes down to 16. The CT-120 has a 120W amp and goes down to 25Hz. By my ear the PB12 Plus produces a cleaner sound (less "boom"), produces output far lower (as the specs suggest), and is obviously far more powerful. Like I said though, it isn't a fair comparison because the "when new" cost of the CT-120 was less than half of what I paid for the PB 12 Plus.

As you said,the PB12-NSD goes lower, and is cleaner and clearer which is the way it should be. This Sub won't put out sounds that arn't on the soundtrack. You also state that the DPS-12 seems to hit harder ( Muddy ) and more powerful. This is the way Subs can sound when they are putting out more Distortion, and they only Seem more powerful. Many Subs when tested by the experts are rated at no more than 10 % THD for "Best Sound" when determining Db output at specific Hz levels for this reason. The DPS-12 starts to distort above this 10% level when it trys to go lower thereby giving you a different sound. If you want to see an expert review done on the PB12-NSD go to your search engine and put in Subwoofer tests-archived SVS PB12-NSD #2. Have a look at the blue Db ratings for this sub. Over 96 Db at 16 Hz and close to 112 Db at the higher Hz levels. The DPS-12 will come close lets say around 25 Hz as an example ( I used to have the #'s ) at 104 Db or so but can't perform across the Range like the PB12-NSD. When you get to the site click off Archives so you can look down your list until you find SVS PB12-NSD #2. The Stats alone prove that the SVS is the more powerful Sub. It will take a bit of getting used to though, until you hear more movies that include lower soundtracks.

If you see Subwoofer tests round 4,5-6th may 2007 (hometheatreshack.com site ) after following original instructions,go through that site.....then click archives at the top.......scroll down subwoofer list and go to page 2. Find SVS PB12-NSD #2 for the review  " OUTDOORS "

Hi Larry777,

Thanks a lot for sharing your informations, very helpful,

I agree with you 100%, the PB12-NSD is a Superior Subwoofer, the Velodyne DPS-12 sounded as more impact or fuller sound, etc, and the SVS PB12-NSD has less punch but with a clean output.

The DPS-12 makes me feel more that I'm in the action of the movie, the PB12-NSD sounded great also, goes deeper, but something else with the Velodyne, just sounds differently.

I'm wondering what if with Dual, 2 x PB12-NSD, will sound better with impact, fuller, as loud like the Velodyne. Larry, does your PB12-NSD fills enough your space, have you considered going with Dual?

How do you like your PB12-NSD, can you tell, hear a difference between your Polk Audio PSW-505. Was it a big upgrade to you, considering the PSW-505 a good subwoofer too, right?

I know the PB12-NSD is better in Sound Quality, but still the DPS-12 made me laugh in movies with a lot bass

My impressions the DPS-12 fills easily my room than the PB12-NSD,

Thank you

Spnai,I havn't considered adding another PB12-NSD sub as one is working ok at this time. I have a wife and 3 children who can handle clean quality sound, but arn't crazy about overpowering unbalanced sound. THE pb12-nsd does the complete job including getting to the lows very well  at any volume level ( A/V Receiver volume ) so I can play it loud or low and everyone is happy due to the sound quality.  Two of these subs together  though would put out I believe about 5 to 6 Db's higher SPL's on average than one,so the sound would be louder and have more impact. The question is do you want or need this much increase when your other speakers are considered for overall sound,which is a personal choice. My Polk Audio PSW 505 is a very good sub also and could hit hard with its 300 watt bash amp ( wasn't boomy or muddy ) but couldn't go as low as I wanted. My main concern was getting the sound from my movie soundtracks as close as possible to the original reproduction as intended by the Director. Thats why I went with the SVS. These additional sounds make the movie more enjoyable for me. The Polk 505 seemed to have more of a low tone presence to it on a continuous basis ( even when the lows wern't called for ,similar to your DPS-12 I would think ) with the highs and mid range sounds behaving like they were comming " through" the lows,rather than being part of a balanced sound on the same plane. Adjusting the SUB Volume can help with this at the expense of this presence that you seem to like.  If your PB12-NSD is set up in the right spot and your A/V Receiver crossover is set at 80Hz or slightly higher depending on your other speakers, I'm not sure why you arn't getting the sound you want. Are your other speakers set to Small ? Make sure you don't have night mode or something similar set on your Receiver which will take away from your Sub output. Do you have the Sub Db rating of your Receiver set a bit above your other speakers ( lets say 3 Db or so ) ?

Hi Larry,

I'm using a Denon AVR-2808CI (AVR-988), my speakers are all set to small, the crossover frequency set to 80Hz to all of the speakers, the subwoofer set to 120Hz, LFE. The Auto-EQ set my speakers, FL 0.0dB, C+1.0dB, FR 0.0dB, SW+3.5dB, SR-3.0dB, SL-3.0dB.

Thank you
