How Many Ohms Are The Klipsch Rp 600m

I used a calibrated DPA 4006 microphone and DRA Labs’ MLSSA system to measure the Klipsch Reference Premiere RP-600far-field M’s frequency response. How many ohms are the klipsch rp 600m? For the nearfield frequency response, I used an Earthworks QTC-40 microphone. For the measurements, I took off the grille. The Klipsch is said to have a sensitivity of 96dB/2.83V/m, which is very high. My estimate was much lower, at 89.6dB(B)/2.83V/m, but this is still higher than is usual for a small two-way speaker. Figure 1 shows that the RP-600M’s impedance magnitude (solid trace) stays above 10 ohms throughout the treble. This means that, at least in this region, the Klipsch is very efficient, drawing much less current from the amplifier than a nominal 8-ohm design. The impedance is lower in the midrange and bass, with a minimum of 3.5 ohms between 180 and 220 Hz. There is also a current-hungry combination of 5.3 ohms magnitude and –42° electrical phase angle (dotted trace) at 128Hz. This suggests that the RP-600M will work best with tube amplifiers driven from their 4-ohm output transformer taps.

A small break in the impedance-magnitude trace just above 300 Hz suggests some resonance in that area. How many ohms are the klipsch rp 600m? I used a plastic tape accelerometer to study how the enclosure vibrated. found on all panels a robust, high-Q mode at 316Hz and a lower-level mode at 422Hz. I would have thought that because these are low in frequency and loud, they would cause midrange congestion. It’s important to note that HR didn’t mention any problems in this area. This could be because he used Blu-Tack to stick the speakers to the stands so they wouldn’t move (footnote 1).

In the crossover region, Klipsch’s response in the far field is a little bit weak. Even with spatial averaging, the tweeter’s level is still too high. So, I wasn’t surprised when HR found that the RP-600Ms “slightly emphasized the leading edges of notes.” HR also wrote that he liked the sound of the RP-600Ms with their grilles on “a little bit more.” Because of the grille, about 1dB less sound comes out of the tweeter between 3kHz and 8kHz. How many ohms are the klipsch rp 600m? The Klipsch’s horizontal dispersion comprises a steady and well-controlled roll-off in the treble on the speaker’s sides as the frequency increases. This usually means that the stereo imaging is precise, but HR noted that the soundstage was “moderately narrow.” Above 13kHz, however, the horn-loaded tweeter becomes very directional, making the speaker a little thin in the top octave in large or damp rooms. In the vertical plane (shown in Fig. 6), a suckout happens 10° above and 20° below the tweeter’s axis, where the two sound waves meet.


How many ohms are the klipsch rp 600m? The RP-600step M’s response in the time domain shows that both drive units are connected with positive acoustic polarity. Before the woofer’s step starts, the tweeter’s step has already started to fade. This suggests that the best blend between the two units is below the tweeter’s axis. Klipsch’s cumulative spectral decay plot (fig. 8) is immaculate.
