Hello Chad329, Jazzcourier is exactly correct by the L150A brochure. Mine is dated 3/81. However, the Lansing Heritage site shows a 1982 full line catalog which states; The L150A is finished in oiled walnut. It is also available in the same custom finishes as the L250; Transparant Black Stain, Indian Rosewood, Macassar Ebony, and White Oak. Grille colors available are Brown, Blue, Black, Rust, Tan, and Maroon. When bought,I was 19 and they were a floor model,walnut/brown grilles. That was 1984 and I still own them,along with many others(larger)JBLs. Your L100 doesn't even compare. They will go very low but like ALOT of power!! Mid-fi amps/receivers don't do them justice (I know,been there done that starting out). They need an amp that can keep good control of the woofers. At one point I had upgraded the x-overs with wonder caps and resistors,new 5-way binding posts and also made them bi-ampable.In my experience they performed very well with my Aragon 4004 and my Krell KSA100mkII,KSA250. Hope all the info helps. Please e-mail me if you have any questions,I will gladly help. Sincerely,Dave Geiss. Poltergeiss@comcast.net.
