Eminence KAPPA PRO-10LF Each Eminence Professional model can be identified by its cast aluminum Eminence chassis that is lightweight and strong. Aluminum does not conduct the magnetic field out of the gap, thereby making the motor strength higher and the stray magnetic field lower. Each chassis and all metal components are coated with an epoxy-acrylic finish using an in-house e-coat process. The thickness of that coating can be controlled to within 0.001”; critical when working with close tolerance transducer motor designs. Then front and rear sealing gaskets are added on each model to accommodate front or rear loading. There are 26 unique models available in the Professional series. Each was designed with a specific application in mind. From heavy-duty subwoofers, low distortion woofers, and super high-power woofers to lightweight neodymium transducers in truncated frames for line arrays, there is an Eminence Professional model for your application. Each product includes a lot of Made in the USA pride. 10" low frequency driver600 W RMS power rating91.6 dB sensitivityEnhanced low frequencyExcels in compact vented or horn loaded bass guitar or subwoofer enclosures PRODUCT SPECIFICATIONS Nominal Basket Diameter 10", 254 mmNominal Impedance 8 ΩPower Rating 600 Watts RMSMusic Program 1200 WattsResonance 39 HzUsable Frequency Range 47 Hz - 2 kHzSensitivity 91.6 dBMagnet Weight 105 oz.Gap Height 0.375", 9.5 mmVoice Coil Diameter 3", 76 mm THIELE & SMALL PARAMETERS Resonant Frequency (fs) 39 HzDC Resistance (Re) 5.47 ΩCoil Inductance (Le) 0.97m HMechanical Q (Qms) 8.97Electromagnetic Q (Qes) 0.29Total Q (Qts) 0.28Compliance Equivalent Volume (Vas) 72.97 liters / 2.58 cu.ft.Peak Diaphragm Displacement Volume (Vd) 271.4 ccMechanical Compliance of Suspension (Cms) 0.37 mm/NBL Product (BL) 14.46 T-MDiaphragm Mass Inc.
