New LASE LW15-1600 Low Frequency Transducer ( Woofer) Incredibly linear frequency response characteristics, extreme high power handling while generating the lowest harmonic distortion of any comparable 15-inch trasducer wtihin its application range.The LW15-1600 uses a fibre loaded cone assembly along with a high excursion triple roll surround. This combination provides remarkable strength and a peak to peak maximum excursion of 52mm.The T-pole also features A special spaced gap demodulation technology, progressively braking the voice coil, providing a much smoother transition for the moving mass as it reaches its maximum excursion limits.Forced air venting system. The transducers low frequency extension, coupled with its extremely low generation of harmonic distortion,also makes it ideal for use within critical listening applications such as studio monitoring subwoofer system. Features: 4-inch, fiberglass inside/outside copper voice coil 1600W continuous program power handling 97 dB Sensitivity 30 Hz ? 1.5 kHz Frequency range Aluminum demodulation ring Forced air ventilation and 14mm top plate for minimum power compression Dual spider design with silicon based dampening control Triple-roll surround and corrugated straight cone geometry We Carry A Full Line Of RCF, Celestion & Eminence Speakers & Drivers If Youre Looking A Particular Model And You Dont See It Here Please Send Us A Message Most Orders Placed Before 2PM and Paid thru PayPal Are Shipped The Same Day; Monday to Friday
