Killed my Avatar tweeters, what now?

[thudfromafar]

Should I just yank the crossover and tweeter outta there?

I'm gonna sell them eventually but dont worry, I'll disclose the details, and take a slight price hit,

[Rick Auricchio]

You can simply disconnect the tweeter wire, but if it's truly dead, where's the harm in leaving it alone?

You should leave the tweeter in the cabinet; removing it would create another port, which would alter the cabinet tuning. You don't want to do that.

[thudfromafar]

I probably should have elaborated more...

No sound comes out of the tweeter except for HISSSSSSSSSsssssssssssss!!

I guess I will just disconnect the tweeter then!

If it was dead there would be no hiss.

[thudfromafar]

True, I guess I was speaking more in terms of function. There's 10x more hiss than ever before... and no other sounds.

[hachi kid]

replace the tweeter?

[hwystar]

I may be one in a few, but I never much cared for them and always disconnected them to begin with, but thats just me.

In your case, the tweeter is likely high-pass only which means you can either remove the tweeter from the circuit at the earliest point (closest to the jack, before the filter/circuit board parts) or just run wires straight from the jack to the 10's. As far as woofer/cab performance/power handling/whatever you'll end up with the same thing, just no clack/sizzle as the woofers are likely not low-passed anywhere. If you have a good-sized copper coil between your + on the input jack and the + on the woofer, this wouldn't apply but I bet you don't.

[hyp.spec]

who needs tweeters anyway?

(flame war starting in 1...2...)

[thudfromafar]

Thanks will33. I'll check into that. I just want to bypass/remove the x-over I guess.

I never used the tweeters. That's likely why they got busted in my cabs... I had the attenuators set somewhat low (not off though), and must have hit em with a big burst, maybe clipping or something, I dont know. I only kept the x-over connected for the possible resale value...

[keyboardguy]

Is the hiss reduced when you turn down the tweeter volume knob?

And have you contacted Avatar how much $$ for a new tweeter if needed?

Mike

Yes, and no I don't want a new tweeter if needed

[will33]

Leave the tweeter in there just to plug the hole so it doesn't cause any weird cab tuning / woofer problems. Don't hook it up though. Then just wire from the input jack like in the series/parallel example here....

http://www.colomar.com/Shavano/4x12wiring.html

The 10's will be getting the full range signal and the tweeter will be out of the picture. Series/Parallel gives you the same ohms with 4 speakers as you would have with 1. ex: a single 8ohm speaker = 8ohms obviously, 4 -- 8ohms speakers also = 8ohms.

[thudfromafar]

I have two 8-ohm 12" cabs, does that change anything from what you said?

[lbwdog]

If the woofers are 8 ohms, the cab will remain 8 ohms. Two cabs in parallel will be 4 ohms.

[Rick Auricchio]

Are you sure:

1. The hiss isn't just coming from the bass or amp? (Try another bass or amp)

2. The amp isn't blowing the tweeters? (And would blow tweeters in any cab)

[thudfromafar]

I'm sure it's not coming from the bass or amp. It wasn't there when we started playing, and then after a few songs, it was way louder hiss. I turned up the tweeter and tapped the bass strings and can't even hear anything out of the tweeters, other than the loud hiss.

I was running my plx1804 into it, that's 900 watts into 4 ohms. I'm pretty sure I just hit a loud note and bam.... although, the woofers were sounding fine -- I'm sure that's because I had a steep high pass filter set, and compression/limiting, and the gains less than halfway... I should have done a low pass also, though...

The tweeter/L-pad is only rated for 50 watts so...... I must have hit a big spike, and L-pads were barely on...

[otis_thick]

Take some black gaffers tape and cover it...you wont hear the evil hiss anymore and when you are ready to sell it take it off...
Now if you are trolling to get us to say we hate foster horns....go outside and play

[brendanbassist]

Is the hiss present even when you aren't playing? Or when you turn down your tone or the highs on your amp? It really doesn't sound to me like the problem is with the tweeter...

Actually I'm pretty sure the new Avatar crossovers have a 12db/octave crossover on the woofer too. So if he just disconnects the tweeter, the woofers won't be running full range.
