Excellent condition Audio Research EC-4 tube 3 way electronic crossover with new set of 6 selected 12AX7 Ruby tubes. The crossover points are on the sticker at back of the unit. You can select the crossover points by swapping out some caps and resistors per owners manual. Slightly complex math involved. Please download a manual and study the work involved before purchasing. Audio Research offer this service also. Please inquire with them. Selling with fixed $25.00 shipping and insurance via FedEx Ground to lower 48 states only.
Questions for the seller |
|---|
| What speaker system did you use this on? Acquired on a trade. The frequencies are listed in the back. The factory settings are typed and my testing in hand written frequencies. You can have them changes at the factory to you liking or do it yourself from the manual you can download. I was going to use it on Magnepan tympany 1D 's with a subwoofer. Never got around to changing frequencies for that application.Thanks. Zaw |
