The RB-81 II is loaded with Klipsch’s proprietary Tractrix Horn technology which produces a unique combination of precision, clarity and effortless power.

4 out of 5 eggsA little bass-heavy; rather expensive; really nice

Pros: --Very clean sound
--Equally good loud and soft
--Clear highs without harshness
--Very solid bass

Cons: --Bass heavy
--More directional than expected

Other Thoughts: These would normally be out of my price range for bookshelf speakers but I found a barely-used pair for the price of the Infinity Primus pair I had been considering (i.e., under 2 bills).

Be sure to position these with the horns near ear level. You'll definitely notice a hit in the highs if you are close to the speakers and get too far off-axis vertically. And that will bother you because the bass is already somewhat overemphasized. Clear, but might be too much bass for some kinds of music.

I have these paired with a small Miller-Kreisel 3-piece system providing a bit of help in the highs. But the MK sub is hardly needed. I turned down the sub volume and crossover because the Klipsch really don't need any help except in the deepest bass regions.

Bottom line: I probably wouldn't pay anything close to retail for these. Certainly not without extensive direct comparison with competitors. But if you see a 50% off sale, and favor speakers with really good bass and clean highs, you could be very happy with these.
