Item Condition - Open Box, Great:

This product works like new, is well-cared-for and in great condition. May show limited signs of wear or use and may be missing non-essential parts, accessories or original packaging.



Great "Boom" For The Buck!

With 1000 watts of peak power handling and 250 watts RMS, the JBL CS Series CS1214 subwoofer handles a serious amount of power. Some of its great features include a frequency response of 35Hz – 200Hz which enables you to hear the wide bass range that you’ve always wanted. And with a sensitivity of 90dB, it provides for better performance at lower power levels. The woofer cone is polypropylene and very light, ensuring maximum performance and efficiency. JBL also uses a progressive spider on the CS Series, which offers better control at the excursion limits, rather than the linear spider commonly used by other manufacturers. This helps reduce distortion even at the highest output levels.



The Sound of quality

Sonic Electronix, one of the leaders in car audio, recently visited Harman, the premium global audio and infotainment group, at their research and development locations in Northridge, California and Detroit, Michigan. The purpose of these visits was to utilize and combine the powerful brand of Harman and the industry leading knowledge behind Sonic Electronix to begin working together on developing future car audio projects.
