A friend bought the RP-600Ms based on Mr. Guttenberg’s review and is very pleased.

He’s enthusiastic, a great ambassador for HiFi and seems like a solid guy.

As a newcomer to this forum, it would seemingly be helpful to have an area dedicated to ongoing reviews of the major Klipsch lines. Maybe I’m just missing that?

Through my iPhone, the midrange on that system was a touch muddy. 😉

As mentioned above by Dean, the 4 db added to their sensitivity measurements after testing @ 1 watt input (2.83 volt) @ a distance of 1 meter. Most manufacturer loudspeaker testing is done in a anechoic test room. So Klipsch adds 4 db of generated sound pressure level to account for the end user's room gain.
Seems rather arbitrary to me, not every user's room is the same size, flooring surface, dampening qualities. But it does make their (Klipsch) published sensitivity data appear really impressive.
For example, a 10 db gain from X level equates to a doubling of the sound pressure level. For example 100 db to 110 db.
Huge difference between playing your LaScalas @ 2.83 volt input in a 12x12' bedroom (door closed) with a tile floor, versus say a 30x30' LR with wall to wall carpeting and many sound dampening furnishings and/or an open floor plan. Actual distance to the listener's ears from the transducer is a big factor too. The room gains for each room in my analogy are quite different. So to test your product (loudspeaker) for sensitivity and add a 4 db room gain arbitrarily on top of the actual test result seems disingenuous to me. Just my opinion. Kipsch sensitivity data is on another level compared to other home loudspeakers. Also as I mentioned above, numbers that second party testing can never realize (such as audiophile websites/testing/review data). Or in the old days published audiophile magazines.
Most home loudspeaker sensitivity numbers are usually 84 to 95 db @ 1 watt input . Try to find any other loudspeaker brand/manufacturer @ any cost equaling 104 db sensitivity in their published data.
Hopefully I made myself clear above. Dean has way more expertise than I.
👍🏻 Many thanks for the thorough explanation.

Well that explains it. 4 db is pretty huge.
Can you please explain “room gain” as it relates to sensitivity.
thanks
