[QUOTE="Crown_amps, post: 2516334, member: 562002"] oad Roaster A remarkable subwoofer full of state-of-the-art technology. The speaker has a Dual voice coil. This feature allows the voice coil to travel at greater distances with very low distortion. A much higher efficiency is achieved. as the inner voice coil is considerably closer to the magnet plate than in most other speakers. The unique design of these 'double driving' hi-tech voice coils and the perfect symmetry result in a very low harmonic distortion. The performance of the speaker is further enhanced by the dual spider suspension in a "push-pull" configuration. Free Case Included! Diameter 12" No. of Coils 2 Impendance 2x4 Ohm Frequency range Power RMS 800 Watt Power Max. 2400 Watt SPL 85.9 dB Max. Voice coil excursion 16.5 mm Resonant frequency 29 Hz Voice coil resistance 2.9 Ohms/Coil Xmax(linear oneway) 0.65" Cone Area - Qts 0.334 Vas 40L BI Force Factor 27.656 TM Magnet weight 200 Oz [/QUOTE]
