Description
The LASE 21LW-4000 21" Speaker Low Frequency Woofer w/ 4.5" Voice Coil
The LASE 21LW-4000 low frequency transducer is the result of many years of development with the goal of creating new levels of professional audio performance standards. This products features improvements in all the key areas of transducer technology. Incredibly linear frequency response characteristics, the highest power handling of any comparable transducer, the lowest power compression. The LASE 21LW-4000 features a fibre loaded cone assembly along with a high excursion triple roll, constant geometry surround: this combination provides remarkable strength and a peak to peak maximum excursion of 54 mm. The new dual forced hyper-venting system guarantee a very efficient voice coil ventilation for minimum power compression and incredible power handling.
