Tool fan needs help with speakers (and electronics)

Will you add room treatment (including a nice rug and pad underneath?

If keeping the way it is, something from Ohm Walsh may be of interest.

Otherwise:

* Outlaw RR2160: ~$900
* NHT C4: $2000 or Polk LSiM 707: $2100
* 2x Rythmik F12-300: $1400 (your cubic space is huge, which needs large subs, and you need dual subs to combat room modes, or get room treatment, but bass corner traps are expensive).
* Maybe, a Topping D50 (in silver to match) if you feel the DAC on the Outlaw isnt great, though this can be bought after the fact.

Use the bass management on the Outlaw to crossover at around 60Hz.
If you want as are somewhat tech-savvy, $300 for a MiniDSP 2x4HD and mic to do DSP for the subwoofers (and the speakers if you also want to).

Get some nice cables: 
* speaker cables 
* subwoofer cables 
* Toslink cable

Thanks for suggestions, everyone. I appreciate it.

Tool sounds incredible on both my Golden Ear Triton References And Triton One speakers.  Clean, clear and very powerful bass. 

Tannoy or JBL. Will give you big soundstage and dynamics. 
If you get models with 10” drivers you’ll hear drums that don’t sound compressed the way they ca do on slimline tower speakers. 

Right up my alley.

Given that your room doesn't have much in the way of acoustic treatment, OHM Walsh speakers might be a great fit.  They are meant to use reflections to their advantage.  Huge soundstage, deep bass.  

You can go new, or buy some used and have John upgrade them.

Or, look at there "deals" on used, demo, or refurbs they have.

Then I would look for a nice integrated amp, probably class D as Ohm's like power and you might get more bang for your buck.

Possibly the powered golden ears (new or used) Tool sounds good when the speakers can thump, the powered bass section will allow you to have less power with your amp selection.

Golden Ears and OHM's both tend to be fairly smooth on the top end, which would also be nice with a room like yours where the tile floor etc may end up being a bit brighter.

I might consider budgeting for a decent area rug in front of your speakers though.
