Sunn Alpha 112r

[Kurt]

Hi-

I recently found one of these amps in my parent's house with a blown speaker (it has one 12-inch). Does anyone know the impedance needed in a replacement?

Thanks!

Hello kurt:
 Those amps came with two different types of speakers. The Alpha112 & 112R had a #81-0162 8ohm (6.4 ohm DC) speaker, the 112P & 112PR had a #81-0166 8ohm speaker. Both used the same basket & coil assy but the latter had a stiffer spyder because of the port tuning.
