Can any one help identify my speakers


Here are some pox. Not home made. Was told they were prototypes of L400 that failed to evolve. They use L91 lenses.

It doesn't resemble Bose at all. It looks like a kit using L300 components in a homemade cabinet. JBL offered separate components with crossovers and specifications for cabinet designs. Many people took advantage of this because it cost less to build your own.
No joke these are probably not prototypes. The slotted down directed "lens" is very JBL like. The slot tweeter with the glass prism is also a JBL inovation. This is probably a DIY experiment although I must say it resembles the Aquarious line of JBLs. Look them up over on the Lansing Heritage site. It would be a rare collectors item if it was a prototype for one of those. I don't think it is one however. When did you get these?? Also the CAR speaker company uses a similar midrange horn lens on there reproduction of the JBL Hartsfield. Good Luck
Mechans, The lens you mentioned is for improved horizontal dispersion of the midrange driver and the slot tweeter is actually acrylic, not glass. These drivers are typical of JBL's 1970s products. Also, the OP's speakers look nothing like JBL Aquarius.
