We used the Rives Pro Audio Kit to perform some in-room near-field measurements of the system and were particularly pleased with the results. All measurements were taken in the newly-redesigned Reference System 2 using a calibrated condenser microphone at 1 meter from the loudspeaker. Full range tests are shown at a 70dB - 100dB scale while low frequency tests have a 50 - 100 dB scale.

Here you can see the overall in-room frequency response of the system at 1 meter with the various "high Frequency Energy" settings available. On the main 4200e LR speakers Reverberant yields a 1.5dB drop in high frequency output, while Damped yields a 1.5dB gain. Depending upon your listening environment, this can be a great way to balance the system and yield a flatter summed response at the listening position. Boundary compensation is only partially shown on this response chart, but it effectively engages at midrange frequencies. While we did not have time to sufficiently test all possible positions, it would appear as if Boundary Compensation in this measurement also showed some gain from 280Hz through 600Hz.

Here we see the lower rolloff of the 4200e LR speaker beginning at around 80Hz. The 4th-order crossover gives us a 24dB/octave slope which is fairly accurately represented here.

Adding the 642e SB subwoofer into the mix, we see that the system's in-room measurement shows usable frequencies down to 22.5Hz. Any anomalies in this measurement are a result of the room acoustics which are currently being treated in Reference System 2.
