No matter what you buy, there is always the chance you may not be 100% satisfied.
It would be best if you can find those speakers to audition.
Another Hi-Fi speaker I recommend is the ultra accurate NHT Absolute Zero, which measures +/- 0.9 dB from 100Hz-10kHz on HTM. NHT also allows a 30-day free return if you don't like them. So free shipping both ways. You will not find any speaker out there at any price that measures more accurately.
NHT had them on sale a few weeks ago for $175 each. They may still give you the sales price if you talk to them in person, especially if you were to buy 3 Absolute Zero + 2 SuperZero ($55 each B-stock). That would be ($175 x 3) + ($55 x 2) = $635 shipped/30-day free trial.
However, I would recommend that you get a Rythmik LV12 sub for $589 shipped. The LV12 measures flat from 19Hz-300Hz (LFE-in/Sub-in from AVR), so you can set your crossover to 100Hz and be perfectly peachy.
$635 + $589 = $1224 shipped.
I used to own 5 SuperZero + NHT 10" sub in a 5.1 setup. For movies and music, they are one of the most accurate speakers I've ever heard. These NHT bookshelf speakers are very accurate, especially the Absolute Zero, but they really have ZERO bass.
But as long as you have a tight accurate sub (like the LV12) and set the XO to 100Hz, it will sound great.
But NHT allows 30-day free return shipping. So you are covered.
NHT also has the 10" sub for $599 shipped w/ 30-day trial if you want 100% risk free for both speakers + subs. I doubt the NHT sub will perform as well as the LV12, but it is 30-day risk free return.
