Show original supplier description
The Kicker QSS674 is a premium 6.75-inch convertible speaker system from the Q-Class line, representing the pinnacle of Kicker technology. Built as a matched component system, the QS 6-3/4 inch separates are designed for pure sound. They utilize Mylar capacitors for enhanced audio fidelity. The system includes external QS Series crossovers, offering flexibility by allowing the use of a single amplifier channel or bi-amplification for greater control. These speakers perform optimally with a recommended power of 100 watts RMS, handling up to 200 watts peak power. Key specifications include a 4-ohm impedance, 87 dB sensitivity, and a wide frequency response of 40-22kHz. The system comes with crossovers featuring a high pass of 24 dB at 2800 Hz and a low pass of 12 dB at 2800 Hz. High-frequency output attenuation can be adjusted at 0, +3, or +6 dB, allowing for fine-tuning of the sound profile to your preference. The Q-Class line requires expert system design and installation experience and is exclusive to Kicker-trained retailers.
