@blin116 - My room was on the cusp of requiring the 3000s, but the room volume for the 2000s overlaps with the room volume for the 3000s. I went with the 2000s, primarily for the cost savings. As you can read in this thread, this was nine years ago, and I am still quite thrilled with them. So, I would think the 1000s will work for you if that’s what Ohm is telling you. That said, while the x000 series has really similar sonics up and down the line, the larger models will offer deeper bass extention and somewhat better dynamic capabilities. Now, I also use a pair of subwoofers with my 2000s. Is it overkill? It depends. I am a bit of a bass freak (well, ok, not "a bit of" - I am a full-on, for life, unrepentant bass addict), so for me, the subs would have been kept even if I had sprung for the 3000s. So, of course, if you ask me, I would take the money you save on the 1000s and buy one, or better, two, good (I stress, GOOD) subwoofers. But I would surely wait for your 1000s to fully break in first. You may not feel the need for any extra oomph or extension in the bass.
And, if you really regret getting the 1000s instead of the 2000s, you can always return the 1000s and get the 2000s (although the shipping will get expensive).
Separately, you should think about deadening the wall behind your couch. Sitting against the back wall is never ideal, acoustically. Most Ohm users agree that "live-end, dead-end" works well. IOW, the front wall should be live, acoustically, while the back wall should be dead (or dead-er). I tried covering up my 60" plasma screen with a quilt, and ended up leaving it uncovered - the sound was better that way. These speakers are different than dynamic-drivers-in-a-box speakers, and respond better to different room treatments and positioning than those speakers. Keep that in mind as you break them in. And, please, allow them to break in. The changes are quite dramatic, IME.
I am powering my 2000s with 150 watts per side as well (although the subwoofers have their own amps, so the main amp is rolled off, first order, below 80Hz), and it is generally plenty of power. I did try out a pair 500 watt monoblocks with them at one point. They were marginally better, but not so much so. I stuck with the 150 watt per channel amp I had. But I may move up to a higher power amp someday. I guess the point is that these speakers will work with lower powered amps, and still sound really good. But, they will respond really well to any improvements you make upstream - whether that is better power, better source gear, even better wires. I am still amazed at how the Ohms allow me to clearly hear differences in upstream cables and gear.
In addition to the helpful folks at Ohm, we on this thread will be happy to help you if you have any other questions.
