      Do you have the specs on these? I just was given a pair of Heathkit AS-21s. The cabs were trashed but have been in storage for 30 years. The speakers are almost new. The horns look like they just cam out of a factory box. I know the specs on the 806's, but not the 474A's or the N-800 X Over.

      Thanks
      Mike

      The N-800 is a 2nd order butterworth with a crossover point of 800 hz. I don't know the value of the pot or how it was wired. Never took it apart. Consider biamping if you have access to active XO's. Also consider replacing the 806 driver with an 802 or 902. Great Plains Audio has 16 ohm versions for about $200 each or buy a set of 8 ohm 9028A from ebay and build your own 2nd order butterworth or biamp.
