ampeg bse410hlf problems

[ROTOBACH]

2 out of the 4 speakers quit working on this cab...i know i had it hooked up wrong to begin with (dumbace i am) ... my gk backline 600 has 2 outputs so i hooked eack up to the 2 inputs ( i thought) on the ampeg cab....found out later one in an input and one is an output on the speaker cab...did i blow the input jack?? or the 2 speakers???

bummed...it sounds like shite..

advice??

thanks

To be honest, I don't think that using two leads would cause any problem at all because the two speaker output sockets on the back of the GK head are wired in parallel and so are the two input sockets on the back of your cab. If I'm right, all it would mean is that you had twice as much conductor between your head and your cab - just as if you were using one really thick, heavy gauge cable.

It may be that something else cooked those two drivers and it was just a coincidence.

Can anyone else back me up on this?

P.S: Funny...I used to own a BSE410HLF and it only had one input socket...hmm.

In general if there are two jacks, they are in parallel.

Some cabs have biamp capability, or other "features" and might have jacks for different purposes, but as far as I remember the 410 cabs generally all just have parallel jacks....

So long as the amp has parallel jacks, and the speaker also does, you don't damage the speaker by connecting two cables. You have a lot more chance of damaging the amp...... in case the cables are NOT identically wired.......

But as far as an "input" and an "output" jack...... nope......

You are correct. There is no point in using two cables, but it won't hurt anything assuming the outputs are wired in parallel (which they are).

300 watt head into 200 watt cab = damaged speakers

I'd be taking a peak inside that cab to make sure a wire/plug connector hasn't just came loose.

I'm pretty sure the BSE410HLF is a 400 watt amp.

Oh wait.. the Backline is an 8 ohm head right? In that case, yeah you probably just overpowered the cab. If it was a 300 watt 4 ohm head you would have been safe. Since the BSE410HLF is 400 watts at 4 ohms, that makes it 200 watts at 8 ohms.

I actually did the same thing with one of my older stacks. Not only was the head 8 ohms, but BOTH cabs were 4 ohm 300 watt. I knew NOTHING about ohms at the time and figured that the 300 watt 8 ohm head was still compatible. Wrong.

Haha good thing for me they were all mix-matched amps I had gotten from yard sales/Craigslist for a grand total of 200 dollars
