Current limitor

palesha · 18th May 2006, 03:00 AM

My friend is blowing woofer from his 2 way active pro speaker. The amplifier doesn't hv limitor circuit. How to solve this problem?

Stop using audio equipment far above the volume level that it can reasonably handle

The best limiter has a pair of ears stuck in it, and a hand to turn the volume knob.

Well said Eva.

Giving advice to others is simplest thing in the world. But helping them is really important.

By educating him to use his equipment properly you will be doing him the biggest favour you can.

Hi palesha,
The advice you have been given is the correct advice. I agree 100%

Physics. The voice coil can only get rid of so much heat, no matter what you want to believe they are rated for in power. I have personally seen many pro loudspeakers burned out due to excessive power. They will only take so much.

This is supposed to be about audiophiles...

I can't recall any driver that doesn't like **** waaaaayyyyyy before it starts to burn.

Am I alone here? Is this thing on?

Hi poobah,
I'm sure the "CLACK" of the voice coil striking the back plate wasn't a hint either.

I always say, if you burn out a woofer, you deserve it!

I found the following project. It looks to be useful. Anybody hv built it?
Project 52 : Audio Amp Output Power Limiter

Hi palesha,
Good thought, but it will not help if the amplifier is not driven into clipping. Also, if you are opening speaker relay contacts, they will burn under load.

An over easy compressor may help the situation. That will limit the levels going to the amplifier. Of course, if your friend turns it up - poof!
