I just had to put this in:

In the mid '70's for a year and a half or so, a band I played in at that time would occasionally practice at one of the band members homes, where we would use a pair of L200's (his father's) for vocal reinforcement. From what I remember, they got the job done well, and the abuse we put them through went undetected when they were used for their intended purpose.

Regards,
Charley
