For bass heads out there it is the cheapest answer and also helps with not having to have the volume so high that neighbors complain. That is why I finally tried near-field is my neighbors complained about the bass shaking things in their house and hearing it.
See...those are exactly my thoughts. I had a little revelation when I placed my sub behind my seat a few days ago. I got a 200% increase in tactile feeling, didn't have to have the sub turned up too high that it was struggling, and some really deep, intense bass. I thought...the whole reason I have a sub is for these things...if I can get this from having it nearfield, then I am getting what I wanted!
Right now the small room in my basement where this is setup (actually smaller than I thought...it's 12'x8'x7.5' plus the little alcove thing at the back) is the only finished portion of the basement. Eventually when I finish the whole basement, I may not have the option of having a sub nearfield, but I am going to do my best to design it so that it's possible. If the subs behind the couch, it's completely hidden, which will make my wife happy as well. win win right?

I think you're right to wait and do sub and amp all at once, and do it right the first time. You can still use the 10 until you upgrade (or if you can sell it) and it sounds like the nearfield location might be an improvement that will hold you over a bit? Definitely go for an amp with DSP or use a MiniDSP or something if you go with a sealed sub, because you can gain a lot from it. I'm about to start tweaking with REW and a MiniDSP, and hope to really tighten up the sound of my new 18s. The best thing is you can, within reason, tailor the sound to a response you prefer, whether that's big output down low or more into the midbass region. I need to experiment with both. Do you have room to use the 18 nearfield?
Thanks, I think that's the best option. I do have room for the 18" nearfield for sure. I can fit it right behind both loungers.
I never really considered DSP too seriously, but I think I'm at the point where the next sub will require it. I've come a long way since being happy with my Polk PSW100. I think I am at the point where I can tell where there are nulls and dips in performance, and having DSP will help that a lot. Is DSP especially important with a sealed build because of the dropoff below 40 Hz and the interaction with the room?

The driver is rated at 600 watts RMS, I ran it off of 120 watts for a week or so and had lots of deep base.
Dsp makes a huge difference, a cheap Inuke 1000DSP used will do the trick.........that's the cheapest bang per buck good performing combo.....you can use your amp for now and save for a DSP model Inuke.
Takes music and movies to a whole new level.
I went from 4, ported 12`s to the single sealed 18 and it blows them away.
This is very encouraging. I don't have anywhere near the output of your 4 12" ported (I think you have 3 BIC F12s and a PL200 right? I believe I read your post earlier this week).
I was looking at the iNukes, and I think going with the 3000 might be a better long term solution for if (when) i decide to add another 18" down the road.
I have to state again that I am super jealous of the prices you get in the US for electronics. Things are significantly more expensive here in Canada, and our dollar sucks right now too.
iNuke3000 with DSP - $430
UM18 - $464
Sheet of MDF - $80
Paint/Stain - $20
With tax it comes out to $1,120. I could probably sell my current sub for about $500, but it's still quite a bit to fork out in the end.
Maybe I should take a road trip down to the US during black friday or something...
