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.

If they were prototypes, and you already know that, how can anyone else know more?

I was told that but don't know for sure and was hoping some one here might be able to shed more light on it.

Kinda look like Bose, but more DIY look.

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.

Etoinshrdlu, These would be great speakers if you are interested in low powered SET amplifiers. The drivers are very high quality, high sensitivity and all have Alnico magnets. Alnico is an iron alloy with aliminum, nickel and cobalt. With a little research you will find the drivers, removed from the cabinets and sold separately, are very desirable. You can sell the drivers and buy something like Dali speakers which are being blown out at Price Dumper. They aren't the best speaker, but these blowout prices make them worth considering.

I was told they were originally acquired in the late 70s.

Etoinshrdlu, I would agree the drivers are from the 1970s. The midrange and tweeter look like the same drivers used in the L300, but the woofer looks different. The L300 uses a 136A woofer which has different mounting holes than the woofer in your photos. I still believe your speaker was a kit. Look at the crossover. I am sure this is a corssover for kits.
