Hi,
I am at the point to buy a set of second hand speakers : BL1, BL2, BL4000, BL3.
I wish that I know what must be physically checked on the speaker to make sure that I am making a good deal?
Also is there any Type / MK / Serial number that must be avoided ?
Is there any particular song that you guys use to estimate the quality/state of a speaker ?
Thanks for your help,
Mat
