QUANTUM QE subwoofers impress with their very compact design. The QE622 subwoofer is almost daintily, but with its aluminum die-cast basket, the dual magnet driver with 2 x 40 oz and the sewn bead, he signals: “Caution, it can become very loud!” The slightly larger subs have a powerful 2 x 63 oz double magnet and just like the QE622 a pole core drilling and also a ventilated T-Plate for optimal cooling. The QE622 has a large 2 “(50 mm) voice coil with an RMS Power Rating of 250 Watts and the QE822 as well as the brand new QE1022 carry a 2.5” (64 mm) Voice Coil with a Power Rating of 400 and 600 Watts RMS. Extremely long-wound voice coils of 30 or 36 mm winding height allow a linear stroke of +/- 10 mm. Both woofers have a double voice coil with 2 + 2 ohms each. This can be used to configure impedances of 1 x 4 Ohm or even 1 x 1 Ohm. Without problems, several subwoofers can also be operated in series on an amplifier.
