Upgrading sub to get a live feel.


I currently have a set of JBL 4319 which has its history as 4310. They are studio monitors and as a result they sound like studio monitors you hear everything, but they lack the physical presence on the low end. They have wonderful mid range and voice presence. I also have a pair of SVS SB1000 to help with the low end. 

I want to eventually upgrade to JBL 4367 with upgraded pair of subs, for this reason, but in the mean time would a sub upgrade be considered before the speakers.

I missed seeing how big your room is.  That's going to make a big difference in how you approach things.

I have a single SVS SB-12 NSD in my small computer room and it provides more than enough bass in that small space and integrates really well with my speakers.

In my large living room, which opens out into my kitchen, I have two SVS SB13 Ultra subs and two Rythmik F25 subs spread out as far apart as I can in a "swarm".

I’ve experimented a lot with this system. My speakers have 3 12" drivers and I thought I didn’t need subs. In fact, it seemed like the speakers had "too much" bass.

I tried adding in just one of the F25s in the front of the room near the speakers and that sounded really good, but only at the sweet spot. Just down the sofa where my girlfriend sits there was a big peak and it was really boomy and sounded terrible.

I tried positioning one of the subs behind the sofa and this was much better, but it wasn’t until I put all 4 subs into play in different locations all over the room that I really noticed a big improvement. The soundstage expanded, the boominess is gone, and there’s plenty of presence. I still have some tweaking to do, but I have to agree that using multiple subs in a large room can have a really positive effect.

The subs I used are overkill for this space, I’m sure I could have gotten by with smaller ones, but I already had them in place for my home theater system. Someone suggested that the smaller SVS subs aren’t up to the task, but there’s no need for sub 20hz extension for most music and 4 of even their entry level subs should make a big improvement in a large room if you have the need and the space for them.

While there’s no need, nor would it be practical to have multiple subs in the small room where I have my computer based system, my large living room with no room treatment benefited greatly from using multiple subs.
More than one way to skin a cat.  Not that I'm endorsing cat skinning by any means.  I like cats.
I'm not sure what the best answer to that question is.  My intuition is that it would be better to have the ported ones farther away in case there's port chuffing.  On the plus side, the PB 1000 will go lower and have more output than the SB 1000.  I suggest giving SVS a call and let them know how you plan to use them and get their advice. 
I would have stuck with sealed subs and got more of the SB 1000 or SB 2000.  Are you using the system for home theater also?
I still don't think we know how big the room is or what the OP's budget is.  Adding two additional subs that have more output should be an improvement regardless of room size.  If the four subs don't have enough output and he can stretch his budget, the PB1000's can be exchanged for something bigger.  Let the poor guy aft least try out what he's bought first. 
If the OP has the budget, bigger is better. It's a good thing to have headroom. Again though, I would suggest that we let him try out the subs he has already ordered (and can return) and see what he thinks for himself.
