All of mine pay fine through an 8 ohm speaker, the Hammarlunds, the Allied A2515, even the Radio shack DX-160 has an 8 ohm speaker. Some have 3 screws for the speaker hookup, one is common, always used, then there is one for 4 ohms, and one for 8 ohms. The DX-160 has the speaker that Radio Shack sold for it, with a 1/4 inch plug. The only communications receiver I have whose external hookup is for high impedence, so it can hook to transmission lines for remote speakers, will be the Scott. Even the Scott has its own built in monitor speaker to use if it is not hooked up to a transmission line. I don't know what sets you have been using, but it certainly has not matched my own experience.
