Klipsch RP-600M II
The most sensitive speaker on this page and the only one with a Cerametallic woofer. Klipsch publishes 94.5 dB at 2.83 V / 1 m, 44 Hz - 25 kHz +/-3 dB and 100 W continuous power handling, in an internally braced cabinet with bi-wire binding posts and a rear Tractrix port. If you are running a low-power tube or class-A amplifier, this is the Klipsch built for it.
Strengths
- 94.5 dB published sensitivity - the highest here, and the reason low-watt amplifiers get paired with Klipsch
- A 6.5" Cerametallic woofer takes the published low end to 44 Hz, deep enough to skip a subwoofer for most records
- Dual binding posts for bi-wiring or bi-amping, and cork pads rather than rubber bumpers for stand use
Trade-offs
- Still passive: an amplifier and a phono stage are separate purchases on top of it
- Published at 15.75" tall and 13" deep - this is a big "bookshelf" speaker and it will not fit a shallow shelf
- The titanium tweeter on an expanded horn is the most forward treble in the lineup; it rewards good pressings and exposes bad ones

Note. Sensitivity is the whole argument for this speaker. At a published 94.5 dB it needs roughly a quarter of the amplifier power an 88 dB speaker does to reach the same level, which is why Reference Premiere turns up so often on the end of small tube amplifiers. Klipsch qualifies the figure the way it does the rest of the range - 2.83 V into half-space - so read it against other Klipsch numbers first.
