Info needed on ADS L1530 speakers.

My husband purchased a set of these ADS L 1530 speakers.  They are outstanding in their field!!  But he's gone and I don't know what year he bought them.  It was in late 1970's or early 1980's I think.  I am selling them now.  I just put them on Craig's List.  Want $1,000 for the pair if you know of anyone who wants them.  I'll send pictures to interested folks, etc. 

I remember going into Waltham Camera and Stereo back in 1980 and comparing L1530 to L1230s. I found the 1530s to be boomy and slow on bass. Ended up getting 1230s. The price was 1200$ for the 1230s and 1500$ for the L1530s. The 1530s were used by Telarc to master alot of there early CDs when they first came out. They bi amplified them.

to the prrson trying to sell try the ADS Facebook group also....that speaker is thought highly of in those circles.... although maybe not at $1 k
