Hi,
yes ,these are a version of speakerlab horns made in the 80"s.Speakerlab actually made 2 types,this one pictured on Ebay,and a 2 part type CLONE of the Klipschorn.Buyers beware dont buy,unless you can confirm it is Authentic.There are no lables on the tweeters or drivers.They were available already assembled,and sold in do it yourself kits.The cross overs are very cheap.I know because a bought a pair of these for 800 dollars from a add in a newspaper.I am in the process of rebuilding mine.For a while speakerlab used Ev tweeters,and in later years made their owm molds and manufactured there own drivers.It is hard to find parts that match,as speakerlab was changing frequency and ohm factors.Speakerlab does not like to talk about these speakers,and has no parts to upgrade them.I was lucky because they original version matched klipsch specs exactly,I cant afford a pair of Khorns so I will stick with these,but it has been a hassle to upgrade them.Another noticable asspect is the way speakerlab mounted ther tweetrs,klipsch mounts them vertical,speakerlad mounts the in a Horizontel manner.In later years speakerlab used passive radiators in the one part cabinet.Also they made the midrange horns out fiberglass.
