Up for sale I have this amazing pair of JBL 4311 speakers that are from the 1970's. This is the studio version of the famous JBL L100's. These speakers work perfectly. Guaranteed for 30 days. Gorgeous walnut cabinets. All drivers work exactly like they should and the sound is pure 1970's bliss. I do have the original grills. The foam around the tweeters is original. I do have brand new foam that I ordered that I can give you. I just prefer the original foam.
