[Elecraft] 4-ohm to 8-ohm question

[Eddy Avila]

My K2 audio output is 4-ohms which I drive into an 8-ohm ICOM speaker with filters. Yes, it works OK, but I would like to match them better.
In the "olden" days I would simply use a 4-ohm to 8-ohm audio transformer, but I can't find them anymore! Really, I've looked at all the suspect places, including eBay and Amazon.
Any suggestions, I just want and easy, simple way to matching the two impedance's without losing power which would happen if I used a resister across the ICOM speaker. I know I can just drive a small audio amp between them, but that means more wires to power up the amp......
Thanks to all
