Subs or Turntable?

OK, thanks. That is easy. The turntable. Given the speakers you have and the TT. 

While your speakers do not plumb the depths, your room is relatively small and they should perform well. Unless you are going for an unnatural kick in the chest. Then the turntable will bring a much bigger improvement in sound quality. 

Although, personally I no longer use my turntable... although I have a $45K vinyl leg. Because my digital leg sounds the same or better. So, at this time in  the evolution of audio, I would no longer invest in vinyl.

Now that you’ve described the system (not sure anyone could give reasonable advice without that information) I’d say go for the subs. But I like @m-db  recommendation on the Rhythmik subs.

Edit:

I just reread your post and saw the size of your room. Not sure why you think you need subs in such a small space. Unless you have some serious bass suckout issues, I will change my vote to a new turntable.

@ozzy62 Second floor, suspended flooring, plus multiple room nodes creating a very noticeable bass suck out from around 45-60hz. Good set up has made significant improvements, but I have always wondered if introducing some phase control in that range, or more placement options could help even things out a little. But I have been hesitant to bring in subs because it’s not a big space and it doesn’t need more slam. Much more about evening out the dip. 

But frankly the TT sounds more fun in my brain so I like where your heads at! 

Don't think of it as one or the other....just which one if first

To ghdprentice's comment, assess your listening preference of digital vs vinyl.  If you are a vinyl guy and this table really excites you then go for it.  

When the budget allows, get one sub and then later another

I vote turntable but a Technics SL1200 G instead of the VPI.  

My personal experience with subwoofers is that they add some benefit in a low percentage of music but can detract and cause issues with even more music.  Even with technically proficient integration of very good subwoofers I clearly noticed issues with bass cancellation and a penalty on rhythm and drive. Especially noticeable on jazz recordings with intricate, fast paced rhythm and percussion.  The subs stole some of the life, energy and burst.
