Hartke Speaker Impedance.

[goingdownslow]

I have a Hartke Kickback 15 combo for playing at home. Although I have had it for some years, I have just noticed the speaker output on back of amp says 8Ω minimum but barcode label on port says 6Ω and also a sticker on the speaker says 6Ω.
Manual specs say 120 watts @ 8Ω and contains !5" 8Ω speaker.
Not sure what to make of it.

Have you had the combo from new? Are you sure it's the original speaker? Could the "6" actually be a badly printed "8" ? (OK, I admit I'm clutching at straws with that one!).

Cheers,
Yes. had it from new.
Have been searching on the web and have found a few references to them (Hartke) using a 6Ω speaker and also that the amp is 120 watts @ 4Ω. Have mailed Hartke support for more info.

Hey Pete,

The Kickback amplifiers are designed to work with the internal 6 ohm speaker for maximum output. The amplfier says 8ohms because we don't want people hooking them up to 4 ohm speakers. I'll check on the nomenclature in the manual etc. but no worries we make thousands of the Kickbacks and they are workhorses and extremely reliable. Enjoy!

So, if you hook an external speaker into the output labeled '4 Ohms', does it cut off the internal speaker?

Just had a look at my Kickback12, Its the same, saye 8 Ohms on the amp, and 6 Ohms on the label.

Nice to get a reply from 'the horse's mouth'. Good for Hartke.
