I've got two Altec 604Es that I'm going to sell. Both were reconed years ago by OC Speaker. Before I sell them I would like to get their frequency response curves tested and printed out.
Does anyone know of where I can take them to get their curves?
OC Speaker doesn't do it, and neither does Speaker City in Burbank, or All Stage Pro in Santa Ana. Of course Great Plains Audio does it, but I've already had an incident with them shipping a speaker back to me, so I don't really want to go with them again.
Any other suggestions?
