Yes I do have that freedom. My initial inclination was to go with dual SB-2000 subs, and use the ARC capabilities of the Anthem 720 to aid in positioning and tuning them. I just wasn't certain if the PB-3000 would be a better fit here. Thanks for the input!

If your primary usage is music then advantage would go to SB-3000. To be honest I’m not sure the the SB-3000 would have much advantage over the PB-10 at the very low end but certainly a big step up in the rest of the range.
I have a 12x15x8 room here and have exactly this problem.

Just got a single SB-3000 in and it's in optimal placement, calibrated with Audyssey, new marantz avr...
Music is amazing, but as I run sound tests, output below 40 hz is pretty limited. and ULF non existent.


To be clear, the music quality and higher bass 40-80hz is phenomenal...But I didn't really appreciate how much advantage ported subs have over sealed in moving air (duh).

I'm going to swap for two PB-1000s or one PB-2000 and would appreciate insights.

It's a pretty square room and I don't have a lot of dead spots...


Advantage of PB-2000 is higher quality sub with cleaner output, and probably enough output for the room, but has potential for nulls.
Advantage of two PB-1000s is massive ULF output, but won't go as low or as clean as PB-2000, with advantage of giving more even base throughout given my AVR has two sub pre-outs.

would appreciate thoughts.

Hi,

First, I probably wouldn't characterize dual PB1000's as having massive ULF. With ported subs, the biggest limitation in low-frequency output is the tuning point of the particular subwoofer, since ported subs roll-off pretty fast below the tuning point. If you want strong low-frequency performance (massive ULF) you need to start with subs which have lower tuning points. The single PB2000 will have a lower tuning point than the PB1000's, and a single PB3000, will have a lower tuning point than the PB2000.

Frankly, if I were you, I would probably upgrade to a PB3000. It is a better sub in every way than the two models you are considering, and it will dig deeper than either of the other ported models.

If a single SB3000 sounds good in your room, without a lot of dead spots, then a single PB3000 should sound good as well. I would always recommend dual subs, where someone has the flexibility to position the subs properly for improved frequency response. (That is not always a simple exercise.) But, I would also recommend starting with the most subwoofer, and the lowest tuning point that I thought I wanted, for ported subs, and then just adding a second identical subwoofer later, if and when I needed to.

Again, if you like having a single SB3000 in your room, then you should also like having a single PB3000. The biggest difference is that it will have far more low-frequency SPL and TR (tactile response) than the sealed model has. And, you would always retain the flexibility to add a second one later if you chose to. But, you would be starting at a much better starting point, in my opinion.

The question of whether to buy one better subwoofer now, or two lesser ones, is a question that nearly everyone wrestles with at some point. The advice to start with the best sub you can is, however, the best advice I know. I think that you had that in mind when you bought your SB3000. As you said, you just underestimated the low-frequency difference between sealed and ported subs.

I hope this helps!

Regards,
Mike

Mike gave you good advice as he always does. Once thing to add. You don't have a very large room (assuming it is fairly enclosed) and in many situations people get decent room gain from a sealed sub in smaller rooms and therefore get good response into ULF territory. Square rooms typically have issues with significant nulls and peaks. When you say you have little under 40hz and no ULF I wonder if some of this is your room and placement. So before changing subs around it may be worth investing in a usb mic plus REW to measure and see what's going on.

If you are quoting this guy as a basis for your recommendation of subs then man you have it wrong. That being said, the monolith is a better sub and the one I would pick.

Thats why i said "subjective feedback"

Also this is the only comparison of the PB3000 vs any subwoofer. It's also better than nothing for anyone who's curious.
I also understand that Youthman is new fairly new to the subwoofer game and still learning (same for myself).

I'm curious why he didn't take any measurements like he did in the past.

Howdy! New member here looking for a recommendation. I've had two PSW-505 Polk Subwoofers but the amplifiers have decided to die off. Looking for a replacment around the same size but with hopefully more performance. Not looking at Polk anymore due to the poor quality of their amps. How would the SB-3000 13" Sealed vs PSW-505 12" Ported compare? Would SVS offer a significant upgrade? Note still planning to run duels.

Audioholics review of 3000 series up so we now have some real data and direct comparison to 4000 series. 3000 is impressive as has been primarily subjectively observed. Comparing max output of PB-3000 to PB-4000 in standard mode PB-3000 equals and primarily bests the PB-4000 at 25Hz and above. At 20Hz and below the PB-4000 retains an advantage which is further exaggerated in extended mode but at the cost of output higher up as expected. Impressive and if one is happy with the extension offered by the PB-3000 hard to justify the PB-4000.

https://www.audioholics.com/subwoofer-reviews/svs-3000

I'm also curious how the PC-4000 compares with the PB-3000. While same driver and amp the PC versions have typically had slightly less output and extension at the low end presumably due to slightly lower total volume. So the PC-4000 might be extremely close to the PB-3000. I like my PC-4000s due to my ability to fit them in my living room but it's possible due to the smaller size of the PB-3000 compared with the PB-4000 I could squeeze them in and they would potentially be less visible.

This has made my decision whether or not to sell my dual 3000s and get dual pb4000s much harder. I do like the 3000s and their output but lacking piano black is the biggest issue I have with them. I am currently running a single pb4000 and was looking to pick up a second one but now i am not sure. Ugh.

Wow. Really can't see much reason to buy a 16U or PB4000 unless you really like the looks. For most people outside of this forum <=20Hz output isn't all that important. Pb3000 doesn't seem to be missing much of anything else otherwise.

pmanyon,

Sir, you just posted the (Perfect) video that I was hoping to find.

I'm getting ready if all works-out to replace my now 20 year old 4 Mirage BPS400 subs.

My choice after extensive research is to get 4 SVS PB-3000 Subs with the, (SVS - SoundPath Subwoofer Isolation System - Black) feet/pads.

I wish I could find more information on having 4 subwoofers versus 1 or 2 Subs.

Especially if the information was relating to the SVS PB-3000 subs.

https://www.youtube.com/watch?time_c...ature=emb_logo

4 SVS PB-3000 subs are it ...........
