XoSo Posted December 10, 2017 Share Posted December 10, 2017 Sitting in my spare room I have an (oldish) Fender 4x10 cab that I bought a few years ago to match to a HH 100w guitar head I was messing around with. It's a curious thing there is no rating plate on the back and no labels on the back of the speakers, there is just a tiny little plate by the rear speaker input that says Fender L082163. It's unported and completely sealed at the back - I imagine it was built as a guitar cab rather than a bass cab. It had no problem at all being matched to the 100 watt HH head but I'm wondering if there is any way to find out the maximum output of the speakers? The reason I ask is that I am about to get an Ampeg PF-500 and I'd like to hook itup it to in the short term until I can afford a proper bass cab. I know all I need to do really is plug the amp in and see what happens but it would be nice to know!!! Quote Link to comment Share on other sites More sharing options...
XoSo Posted December 10, 2017 Author Share Posted December 10, 2017 Sorry, should have also added, I only want this set-up for home practise, not for gigging. Quote Link to comment Share on other sites More sharing options...
Bill Fitzmaurice Posted December 10, 2017 Share Posted December 10, 2017 Even if you knew what it is there's no way to know the maximum output of the speakers. If what you're really asking is what is the maximum power input rating it doesn't matter all that much, it will distort long before that point is reached.

XoSo Posted December 10, 2017 Author Share Posted December 10, 2017 quite, and I'm almost certain that at low 'home practise' volumes the cab will easily be sufficient. I ask more out of curiosity than anything - i'm a very 'untechnical' person and didn't know if there was some way to test speakers or not, I suspected not to be truthful.

Bill Fitzmaurice Posted December 11, 2017 Share Posted December 11, 2017 The way that driver manufacturers test power handling is to feed them pink noise at a given voltage for a given time period. If the voice coil doesn't burn out they do it again at a higher voltage, and so on until it does burn out. I don't recommend you try that.

XoSo Posted December 11, 2017 Author Share Posted December 11, 2017 Lol. No, quite!! Think I will use it with caution until I can afford a bass cab Quote Link to comment Share on other sites More sharing options...
Jack Posted December 12, 2017 Share Posted December 12, 2017 (edited) You can use a Powersoft K20 and your favorite dubstep track to find the limit quite easily. Once. Edited December 12, 2017 by Jack spelling Quote Link to comment Share on other sites More sharing options...
MoonBassAlpha Posted December 15, 2017 Share Posted December 15, 2017 Apparently, Wembley Loudspeakers offer a service where they put the magic smoke back in to loudspeakers! Quote Link to comment Share on other sites More sharing options...
