Built using the latest in subwoofer technology, Ultimax subwoofers are the pinnacle of low frequency driver design. An Ultimax subwoofer test the strength of your foundation with fast, articulate, gut-wrenching bass. Dual 2 ohm voice coils allow for stereo 2 ohm and mono 1 ohm wiring configurations when connecting to high current car audio and professional audio amplifiers to extract maximum power. For home audio applications, simply wire the voice coils in series for a benign 4 ohm load for greater amplifier compatibility. To improve power handling, increase thermal management, and reduce power compression, Dayton Audio designed the Ultimax Series with large black anodized formers and vented pole pieces, under-spider ventilation, and two-layer copper voice coils. Over 1-1/2" of travel (3/4" Xmax) is kept completely linear through the use of dual spiders that also limit distortion and rocking modes. "Tall-boy" rubber surrounds with integrated gaskets maintain driver surface area during extreme excursion moments. Thick, one-piece Nomex honeycomb covered cones are covered with woven, heavy-duty glass fibers creating ultra-still cones that resist deformation. A large copper sleeve and copper pole cap in the motor reduce energy storage from inductance, with the side benefit of lowering distortion for "faster" response. Large dual-stacked, high-energy magnets handle the heavy lifting and bring Qts down to a level where Ultimax subwoofers can be used in vented or sealed cabinets and enclosures. Cabinet Recommendations: Sealed 1.5 cubic ft. (net internal) with 1 lbs. of Acousta-Stuf polyfill, f3 of 35 Hz with a 0.707 Qtc alignment Vented 2 cubic ft. (net internal, not including driver or port volume) yields an f3 of 22 Hz Product Details Speaker Series Ultimax Series Model Number UM12-22 Color Black Unit of Measure Each UPC 844632099250 Warranty - Parts 5 Years Warranty - Labor 5 Years Product Shipping Weight (lbs.) 23 Speaker Type Subwoofer Power Handling (RMS) 600 watts Power Handling (max) 1,200 watts Continuous Program Power -- Impedance 2+2 ohms Sensitivity 86.7 dB @ 2.83V/1m Frequency Response 20 - 1,000 Hz Voice Coil Diameter 63.5 mm Magnet Weight -- DC Resistance (Re) 3.2 ohms Voice Coil Inductance (Le) 1.25 mH @ 1kHz Resonant Frequency (Fs) 26.2 Hz Mechanical Q (Qms) 3.62 Electromagnetic Q (Qes) 0.71 Total Q (Qts) 0.59 Diaphragm Mass Inc.
