Up for sale, a matched pair of JBL K120 speakers in excellent condition and in good working order. With heavy duty alnico magnets and 4" voice coils, the K120 is an extremely efficient and powerful speaker, easily able to handle 100 tube watts with crystal clear top end and rich lows. These speakers have close serial numbers and both have their original JBL cones. In fact the only difference between the K and D series 120 speakers is the extra ribbing on the K's surround to better handle bass frequencies.

Both speakers retain their original cones and aluminum dust caps, and the cones are stamped with the 21032 cone code, which is identical to the code seen on original D120Fs. The frames are clean, the JBL labels are minty, and both speakers are rated for 8 ohms. Each speaker has been tested at near peak wattage and works as it should with no tears in the cones or rubbing of the voice coils.

This vintage, clean, and original K120 pair is ready to be installed in your guitar or bass amp!
