Hey guys. I'm interested in getting a Hartke LH500 but I have a slight issue with that.
The head has a 4Ohm impedance but Hartke don't make a cab matching its impedance that has enough wattage. Is it okay to match the 4 Ohm head with an 8Ohm cab?
(If it helps - The head is Tube)
Cheers

Its preamp is tube but the power amp bit of it is solid state.

What this means is that 4 ohms is its minimum impedance- use a lower impedance total load (speaker cabinet or cabinets) and it'll fry. But you can use a higher impedance than that, and it'll be just fine, but it'll lower the wattage which it puts out.

According to its manual it puts out 350W at 8 ohms. That lower wattage will also make it easier to find suitable cabinets which can handle the wattage.

I'll have to put the Classic T models on my to-try list. Shame the finish options there are Anachronism Gold, Nuclear Waste and Aged Clown, because in principle the plaintop is right up my alley.

Awesome, so that means that I can use higher impedance cabs with it, right?

^ Yeah. I mean it said in the manual that you could use an 8 ohm cab with it (and even quoted what the wattage would be if you did that), and even on the back of the thing it has two 8-ohm jack sockets. I'm guessing that means it's ok.

If only impedence was that simple... but as a general rule, you'll be more than fine with an 8 ohm cab.

Brilliant!
Cheers guys

I'll do a big write up about impedence (and hopefully kickstart the new bass FAQ thread in the process). It's a lot more complicated than 'cab x is 8 ohm, cab y is 4 ohm.' Those a re what's called nominal impedence- depending on the frequency being played, the impedence can dip to as low as 2 ohms!

Oh absolutely, I'm aware it's frequency dependent, don't worry. I just meant that for the purpose of this thread and for what he wants, "It'll be fine" is probably a perfectly adequate answer. (I'm guessing that companies, when they say what impedance is safe to use, are also aware of this? I hope so, anyway )

Good luck with that FAQ thread. I'm currently in the process of trying to do one (actual several ones) for the guitar and G G&A forums, and it's a pain in the ass. Haven't actually done any work on it for a few weeks, I'd better get back to it at some point I suppose.
