I have a Hartke 15 Kickback combo for playing at home. Taking the speaker out to get at something rattling around inside I noticed it had a sticker saying 6 ohm.
The manual spec says 120 watts into 8 ohms, and also 8 ohm 15" speaker. What gives?
I haven't got a meter handy to check if this may have been the dc resistance, but surely it should be marked with the impedance.
I used to have the same combo and the speaker was labeled 8ohms. The amp was also an 8ohm minimum amp. Sure part of the label isn't worn off? Get ahold of a meter, if it's reads anything above 5 - 5.5, it's an 8ohm speaker.
Dc resistance is 4.6 ohm.
I have found other mentions on this forum and the web of it being a 6 ohm speaker, but no explanation of the effect on the amp which has/says 8 ohm minimum load.
Are Hartkes specs wrong or does this combo have the wrong speaker in?
That reading would indeed be a 6ohm speaker....wierd.
If it's the original aluminum cone hartke driver it belongs in there. Maybe a way to get a little more power from the amp but still can't handle a real 4ohm load?
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!

Larry's too cool, what a guy. He's right, mine was super reliable and sounded damn loud for what it is. Eventually sold it to fund other stuff but sometimes I wish I wouldn't have....handy little thing.
Hi i have a Laney Richter 120 watt kick back style amp and about 10 yrs ago i replaced the original speaker with a 12 inch Hartke which i was under the imperssion was a 8 ohm but is now a 6 ohm..am i still able to add a 8 ohm speaker box to this amp??
