My home intercom/music system uses 45 ohm speakers, with a series pot to control (reduce) volume at the speaker. I have one speaker outdoors that's gone bad, and the OEM replacement is outrageously priced. I can't find one for less than $50. I'm looking for any reasonable solution that saves money.

I've tested a normal, lower impedance speaker and it does work, although I'm concerned it would eventually cook the amp. I could eliminate that concern by adding a cheap $20 amp such as:

But I don't have power installed near the speaker. It's not too far away though. Short of adding a power amp, are there other clever solutions to consider?
