The monkey on your back, or in this case, the monkey in the room is The Room! @helomech nailed it: you are really constrained by your room. 9X11 by??? 6 to 7 feet since it is a basement??? Cinderblock???
You really should consider a 'near-field' setup like the one @helomech suggests. Taking the Tekton DIs out of the equation, you generally should be able get a higher quality speaker if you choose a monitor over a floor stander, for the same spend. You have said 2.1 is a possibility...it would be great if you could incorporate a sub with the monitors, or preferably 2 subs. But the room is going to limit this...it will be easy to overwhelm the room, so something that is delicate, has a smaller woofer, and doesn't go down super low. If you don't, the excess energy will just get sent up the walls and the flooring above you, and into your home. You've said you like hard rock. : ) Given the room size, front porting speakers or transmission line speakers that port to the front or to the bottom would also be good options.
Talk to Eric. Maybe it is better to go with one of his other models, and incorporate a sub, one of his or another brand's. I still think the DIs will work, just leave a sub out of the mix, and plan on major room treatment in your situation. @teajay recommends Linear Tube Audio as a fantastic pairing for the DIs, and this would help you accomplish (along similar lines) what @last_lemming is recommending.
Given your room, I still recommend a headphone setup as a very good option. I purposely mentioned the 10K level to give you a feel for what you could accomplish for not that much more than your stated budget of 5-6K. The 5-6K, wisely applied to the complete chain will easily get you to around 85% of what the 10K spend would and will kill the equivalent spend for a speaker setup. Plus you get to take the room completely out of the equation. Set the room up for comfort and use, as you prefer, without having to spend a dime or time on treating it.
