These 12 inch, low frequency drivers, are the original ones that came out of the QSC K12 speakers. Both speakers had issues with the power modules and these two low frequency drivers are all that I've decided to salvage out of them. Everything else has been binned. These low frequency drivers are in perfect working condition - no tears or rips. Please note that they are sold as a pair. Please bid only if you are sure that they are exactly what you need as a replacement driver for your QSC K12. Also please do not confuse these low frequency drivers with the drivers used in the QSC K12.2 (or mark 2 speakers), as those use different drivers with a lower impedance. Starting bid £99, no reserve, no early finish and no international shipping. Free collection from Ipswich or I can post and I shall do my best to pack them up as good as possible. If you have any other questions please let me know and I shall get back to you. Thank you for looking.
