This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the 3010 satellites (purple trace), 3070S subwoofer (blue trace), and 3090C center channel (green trace). All passive loudspeakers were measured with grilles at a distance of 1 meter with a 2.83-volt input and scaled for display purposes.

The 3010’s listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +2.00/–2.22 decibels from 200 hertz to 10 kilohertz. The –3dB point is at 103 Hz, and the –6dB point is at 66 Hz. Impedance reaches a minimum of 4.89 ohms at 7.5 kHz and a phase angle of –43.05 degrees at 3.5 kHz.

The 3090C’s listening-window response measures +1.49/–1.07 dB from 200 Hz to 10 kHz. An average of axial and +/–15-degree horizontal responses measures +1.53/–3.70 dB from 200 Hz to 10 kHz. The –3dB point is at 100 Hz, and the –6dB point is at 81 Hz. Impedance reaches a minimum of 4.60 ohms at 7.7 kHz and a phase angle of –38.83 degrees at 2.9 kHz.

The 3070S’s close-miked response, normalized to the level at 80 Hz, indicates that the lower –3dB point is at 34 Hz and the –6dB point is at 30 Hz. The upper –3dB point is at 174 Hz with the Crossover control set to maximum.—MJP

Mark, how would you say these compare to the RSL or Wharfedale systems you reviewed a while back? I know that's not a fair question to ask, both because of the distance of time and the sheer quantity of products that pass through your setup. I had been planning to get one of those, but this Q Acoustics system seems like it might prove a bit disruptive to the status quo.

I'm also looking a purchase real soon on a 5.1 setup and have been considering RSL CG3 system based on the reviews I've read and after speaking with RSL on the phone. I would also like to know what a professional's opinion would be between the RSL CG3 or CG4, these Q Acoustics, and the Wharfedale system that was reviewed on this site last year. Thank you all for your opinions, advice, and great website.

when giving performance ratings, is this in comparison to a specific price range. for example, how would you rate this vs. the Elac unfi bookshelf 5.1 system.

I also have a similar question to what was posted earlier. I am looking at the RSL CG4 5.1 system and would appreciate your feedback on how this compares to the Q Acoustics system reviewed here with one small change. I am considering the 3020 instead of the 3010 that comes with this package and would thus purchase individual components. I appreciate your opinion!!!
