help troubleshooting samson db500A powered 15 main

Basscrime · 11th January 2012, 06:58 PM

Hi, i bought a pair of samson db-500A powered 15 inch 500 watt speakers used of craigslist a while ago, used em for a fiew shows and love em.
there biamped, the tweeter and 15 each have there own amplifier.

PROBLEM:

I was mixing at home the other day and noticed that one of the 15's in one speaker wasnt playing anything, i was only getting sound out of the tweeter, so i turned the speaker off, then back on again and the 15 kicked back in. the same thing happened again a day later but this time it didnt kick back in as soon as i restarted it, so left it off for a while, turned it back on and the 15 was playing music again.
turned it on this morning, and the 15 played music for one song, i played another song 10 mins later and my 15 isnt playing anything again!!
I have never heard of or seen a problem like this before, could it be a loose connection to the amp for the 15?
i have shows coming up this month so i need my FOH mains badly.

any and all help is much appreciated.

i was just listening to a track while i had the 15 working, and then it cut out but it didnt cut out, it faded out like someone slowly pulled a fader down on a mixer, this is verry strange...

i'm convinced there is a design flaw. I have the same problem with one that a client brought for a repair. I'll be able to tell you later, once i've figured this one out.

Well, come on, why not share the solution with all of us?

When I see that symptom in anything, my first reaction is dirty cutout contacts on a jack. But it certainly coul dbe many different things.
