I recently bought an Aguilar Tone Hammer 500 and it was great when I bought it. Recently though it has started hissing through my bass cabinet. It also hisses through the direct out XLR output into a mixer. The Tone Hammer is 250watts at 8ohms and the speaker I use is a Hartke which is 200watts at 8ohms. Did the fact that the speaker is a lesser power than the amp blow the amp? I am going to send it to Aguilar to repair since they come with a 3 year warranty but I need to know if I should also get a cabinet that is a higher wattage.
Any help would be unbelievably appreciated! |

The power rating of the cab has nothing to do with your problem

Designers tend to try and limit this noise but to do so adds expense. Bean counters don't like extra expenses so often they overrule the engineers saying a little noise is good enough.
Edit: As Munji opined sometimes it IS the nature of the beast.

At least it is absolutely free of hiss and noise.....

None of my cabinets have tweeters/horns so those of you with such devices in your bass cabinets may hear more hiss than I do, which is basically, none, at any sane volume level.
