Klipsch RP-600M II

The spec. on the two-way bookshelf speakers like Sierra 2 looks impressive (34hz-27khz) but be cautioned that, with a ribbon tweeter, its mid-range frequency response might be compromised.  Ascend is certainly doing a better job.  This similar limitation is shared by GoldenEar BRX.

They’ve received many good reviews...I found the Triangle Borea 03 and Elac Uni-Fi 2.0 to be equally as good but different, and also some Dali’s but don’t remember model......the Klipsch is regularly available as "open box" from authorized dealers for about $450 including shipping...and if it matters, most reviews seem to find the Klipsch much less sensitive/efficient than advertised...fortunately I found a pair of Salk Monitors at a great price and didn’t have to decide, though it’s a much more expensive speaker...

The Mark 1 Klipsch rp600m is very good enough if you know how to match it.I am playing them this morning they sound so close to my Diapason Adamantes.

i have these lil klipsches in a bedroom in our country home

they are ok for casual listening, they can get raspy when pushed but certainly have a lively sound, and are efficient, so one can use a smallish amp
