100w SS head thru 75w speaker?

[twanguero]

I had been running my yamaha G100 head through a 2x10 cab that was listed as 60w. It sounded great but I wanted to try the detuned 1x10 cab thing with it. I have a 75w ragin cajun I was thinking of trying with this.

Now, I know 100 solid state watts is not the same as 100 tube watts. How does this relate to speakers? I can never get this amp above 3 or 4 on stage, so do you think the Cajun would be in danger of blowing?

The short answer is: no worries. The speaker will overheat before crapping out. I unintentionally ran 130 watts of 6L6 tube power into a single 100 watt Scumback for 3 hours at heavy volume and distortion. Kept working and continues to work to this day (see sig). The back of the speaker got really freaking hot... but didn't blow.

So, based on my experience, go ahead and try out the Rajin Cajun. It's supposed to be a powerful speaker in it's own right... so you may find it to be perfectly fine even after several hours of use/abuse.

Make sure you have the ohms correct and (just for safety's sake) every once in a while make sure the speaker magnet's not overheating.

I have a G100 2x12 and almost sold it. Love that amp man!

Sigh. So because you got away with it, all scenarios are safe? :jo How do "have the ohms correct" with a solid state amp?

To the OP, a watt is a clearly defined unit of power. The speaker doesn't know if it's hooked up to a tube amp or a solid state. If the maker of the speaker says don't put more than 75 watts into it, I'd take their word for it.

Yup. Experience has been a tough teacher for me, but I gladly yield to your opinion.
8 ohm output into 8 ohm speaker = "ohms correct".
I still say, try it.

Solid state amps have a minimum impedance. You don't need to match output like you do on a tube amp.

Thanks y'all. Yeah the g100 says 4 or 8 ohms on one speaker out and 16 if I use a&b speaker outs. So I'm alright there. I'll try it and see if what everyone says about the one speaker detuned cab is true. Maybe not on a gig yet... Wouldn't wanna blow a speaker on stage.

[Darth Tater]

Your solid state will produce the most power into 4 ohms, the least power into 16 ohms, so go as high as possible.

I'd be careful running your 100W amp into the 75W speaker. If you tend to crank the amp you could fry the voice coil of the speaker. That's why speakers have wattage ratings....

[twanguero]

I never get this amp up past 9 or 10 oclock, so maybe it will be alright. I was babying it with the two 30w 10s that were in it before. I've heard the detuned 1x10 is even bigger sounding and the Cajun is a better speaker than the others, so I'm gonna give it a try.

You're right, I wouldn't try it at 4 ohms. Maybe 8ohms will be safe. Thanks for the input!
