4311 should be the old L-100.. the older models 4311 have the alnico drivers, and some prefer the older midrange driver with the inverted dust cap. I prefer the better woofer of the L-166 and recommend that model.. you should be able to find a pair on ebay for around $400.
Which JBL 4300 series speaker is recommended?
Looking for a JBL speaker system for a second system to play mostly rock music.. There are lots of 4311 and 4312 speakers available. Which of the series are recommended or are there any others that would be recommended instead. Not looking to spend an exorbitant amount but am flexible.
