Impedance and Sensitivity
Q Acoustics Concept 30's nominal impedance level is
6 ohms but can go down to as low as
3.9 ohms, and has a sensitivity of
87 dB.
Sensitivity
Bookshelf Speakers
Nominal Impedance of the 6 Ohms makes the Q Acoustics Concept 30 a relatively difficult to drive speaker compared to more frequently found 8 ohms speakers from nominal Impedance perspective.
Sensitivity
With a sensitivity level of only 87 dB, Q Acoustics Concept 30 is a difficult to drive speaker from Sensitivity perspective, make sure to choose an amplifier with a high output if you like listening to your music at high volume levels. You may especially have a hard time using Tube amplifiers which are traditionally very low power compared to Class A/B or Class D amps.

Input Type
Concept 30 has Binding post type connectors and lets bi-amping/bi-wiring. Bi-wiring can enhance the overall transparency of your loudspeakers by using separate speaker wires for the low and high-frequency drivers from a single amplifier. Bi-amping, on the other hand, involves using separate amplifiers for the high and low-frequency drivers, potentially resulting in a greater dynamic range and reduced distortion.
