Hi Guys,

 

I've seen many threads comparing the PB12-NSD vs the PB12-Plus but what do you think or the PB-2000? Is it worth it to drop another 500$ (I'm in Canada) for the Plus?

 

I already bought the PB-2000 like 3 weeks ago through SonicBoomAudio.com. Was supposed to have it last week and now they told me they won't receive the PB-2000 before the 20th of march.

 

So here is the question... Get the new PB-2000 or spend 500$ for and older but bigger model?

 

 

Thanks!

Thanks for the reply. In term of output (mainly for movies), will I hear and feel a big difference between both? I do like that "chest thump" feeling on action movies :)

 

Also, could you give me more information on that variable tuning feature... I'm sort of confused with the info I could find on the net...

All depends on how loud you listen...if you plan on listening at reference levels, I need to know your room size because neither sub may be up for the task. Variable tuning allows you to block the port(s) and achieve deeper bass extension at the expense of 40-80hz output. If you want chest thump then all ports open would probably be the best since chest thump frequences are centered around 80hz.

Thanks a lot for your time Basshead,

 

Here's more info to work with:

 

Receiver: Denon AVR X-4000

Front: Polk RTIa9

Center: Polk CSIa6

Surround: Polk FXIa4

Sub: Polk PSW125 (suck...)

 

Room is 14 x 18 with 8 foot ceiling which is roughly 2000 Sqft. There's a door size opening front left.

 

I use it 90% for movies and 10% music. Volume level is variable depending if my son is at home or not but often the volume on the receiver is -10b to 0db... Those polks are a bit inefficient speaker... They sound well but requires tons of power. Next buy is an Emotiva XPA-5 when WAF goes up after that sub comes in...

Option 3 is the best: Get the new PB-2000, and then save the difference towards a 2nd PB-2000 later on. If the PB12-Plus is indeed only 3db more than the PB-2000 (not doubting basshead, just don't know), then dual PB-2000s should provide you more maximum output. Duals also have the potential to produce a smoother in-room response through a wider seating area.

Yes I have the RTI-A7 powered by aAdcom GFA-555II, made a world of difference. The A9 definitely need a good power amp.


That being said I would get the PB12+, it will do the best job keeping up with your A9's especially after you feed them some emotiva power!!

Id have to agree and point you to the plus series unless you went for dual pb2000s at the same price range

Dual will provide more output? I really thought it only produce a smoother in-room response through a wider seating area... More choices...

 

Also here in Canada, Dual PB-2000 (900$ each) is almost the same price as the PB13-Ultra (1900$). If I drop 2K on the sub... My Amp will have to wait for a while so my only choices for now is really going single PB-2000 or PB12-Plus...

 

I guess I'll go for the PB12-Plus...

 

Thanks a lot guys!

Duals can easily provide +6db more output than a single sub of the same model.

...EDIT...


If Bill Fitzgerald says something opposite than what I believe I am going to take his word. He knows more than me

That only happens with you place both subs in the same location I thought. But spreading them out still gives you a 3db boost

No. I used to think that until Bill Fitzgerald told me otherwise and said use the 6db number. Didn't quite understand it all (you know Bill's explanations) but it seemed to make sense

+6 db is tempting but my wallet doesn't agree :)

 

Last question... Is there a "break in " period for a sub or I can just crank it up when I receive it?

Well according to Ed Mullen the PB12+ has a 6db advantage over the NSD, the PB2000 has 2.85db average advantage over the NSD. Most of that is above 30hz. I suspect the PB12+ probably has a bit more then that down around 16hz-20hz. The PB12+ of course is the more robust subwoofer, being its massive driver and variable tuning. I do not see a single PB2000 keeping up with those A9's with a good power amp. Your talking 6 -7" drivers that will hit with authority down to 30hz in room. My A7's actually dig to about 28hz before rolling off sharply.


That being said, Dual PB2000's or a single PB12+ would be a good choice, I was merely sticking with the OP's options. However it is the norm for threads here to take a left turn quickly.

I'm paranoid and like to give it an hour or two of breaking in before I start blasting it. And I don't like the idea of blasting it straight out of the box when it's been sitting on a cold FedEx truck. But that's just me.

I was actually surprised that you didn't beat me to that suggestion

I know I almost suggested it....however I have been trying to refrain from pushing folks a different direction even if it imo is for the better. Not everybody wants duals even tho again imo it is a must.



The only time I was ever happy with a single sub is when I had s massive DIY passive 15" sub stuffed in closet of my 10x12 bed room. This was back when I was 14yrs old and I am 32 now. Tells ya how long I have been playing with Bass.

Reading subwoofers thread after another... I'm now thinking of keeping my order for a PB-2000 and... buy another in the next months... My receiver has Audissey Platinum with Sub EQ that can balance 2 subs separatly...

 

I think the best upgrade path for me is:

 

1- Getting rid or that Polk PSW125 and replace it by a PB-2000 (should be a good difference... I hope so at least)

2- Get that Emotiva XPA-5 to power these watts-hungry polks

3- Buy a second PB-2000...

 

Unless I win the lottery tonight ;)

I think going with dual PB200's is the way for you to go. Also what are you planning on crossing your A9's over at??? I ask because even a cheap $200 sub can usually put out more bass under 80hz than even really good towers. Now with a cheap sub the bass wont be as clean as the A9s. But I would try crossing them over at 80hz or IMO 60hz at the lowest. I find in my setup 80hz crossover all around is the best. So I guess my point is, is an external power amp necessary?

I don't know if my settings are correct but for now I use these with my "awesome" PSW125:

 

RTIa9 Front: 80 Hz

CSIa6 Center: 90 Hz

FXIa4 Surround: 110 Hz
