LSi15 tweeter not working

I'm wondering if there isn't a short inside your amp that isn't shorting out right now.Political Correctness'.........defined

I hope not, its going to suck if I get this all fixed and it blows up again

damn, the multimeter is fairly basic and can only test things like voltage, resistance and amperage. I was hoping I could measure the resistance of the cap to indicate at least if its making a connection or now.
Thanks for the help by the way, I know a new crossover is on the way but I am just curious what died exactly on this one -
The caps won't measure a short unless defective,so they are likely fine unless there are signs of physical damage to them.If the resistor measures open circuit that's why your tweeter is not working.I would also suggest removing and disconnecting the tweeter and check the DC resistance across it's voicecoil leads.If it also measures open then it's also toast.

I did check for resistance across the tweeters voicecoil leads, it measured open.
I tested all the resistors and the only one that's open (bad) is the one for the tweeter.
I tested the coil things (I don't remember what they are called lol) and they tested short.
the yellow capacitors I couldn't get to test, but a couple of the black ones did test "short"
based on that I imagine I have some bad caps, or what else could it be? -
OK looks like you have atleast a resistor and tweeter failure.The inductors will measure a short since they are just coils of wire.The bigger caps may initially measure as short but after they start to charge will not if you leave the meter on them for a bit.I did check for resistance across the tweeters voicecoil leads, it measured open.

IIRC, the drivers all worked, so the rest of your board components are ok.
What I would be concerned about is what took out the resistor and tweeter. That answer has to be in the amp.Political Correctness'.........defined

yeah they sure didn't blow up on their own lol, which is why it concerns me that emotiva says the amp is ok -

That's Emotiva's response to the problem.
Polk's response ?Kenneth Swauger wrote:No problem, Polk will take care of you, you're in good hands
Blindsay, I hope you can see the difference.
And, as a thought, when you get your Emotiva back that is ok, pop the hood and have a look-see under the hood. Will you see any components that have been changed ? I have my opinion, but do that. Pop the hood.
That will, IMO, also tell you a lot.Sal Palooza -
I agree when you get the amp back check for replaced parts, did you write the serial # down to check if they send you a replaced unit.
I'm sure Emotiva will have put the amp through a proper set of tests to check for shorts and or other issues, but if it shows nothing then what to do.?
Are you sure your not leaving something out that maybe you forgot, like we're you playing the speakers very loud just before turning them off, and when you turned them back on this happened?
How often have we heard this story about, well it was working last time I turned it on..
From what I have read the UPA's do not have a known flaw, but the Polk resistor is a known flaw.
I'm not saying that is the cause and or could do the rest of the damage as well, but it has to be something.mrbigbluelight wrote: »That's Emotiva's response to the problem.

I do have the serial number recorded, but I imagine they would repair it, the parts inside the amp seem pretty modular.
I know everyones first instinct is that I played it too loudly but I promise that's not the case, I live in an apartment with cranky neighbors so I cant turn it up very loud. Heck the night before when I had the amps hooked up and working it was so late I had them quieter than even on just the onkyo. It was really just to power them on and make sure they were working. The next day when I went to power the amp on as soon as it clicked on then it all went to heck.
As far as trying the amps out to make sure they are ok. I don't really have any speakers to guinea pig but I do have a pair of Cerwin Vega LS-12's that have a fused input so they might be more likely to surive if something goes wrong, unless you guys have any ideas how I could test each amp to make sure they are not a time bomb waiting for me to just power them on -
is there any conceivable way that the resistor blowing could take out the tweeter with it? Emotiva still suggests the amp is fine

It's likey the excessive current that nuked the resistor also fried the tweeter .is there any conceivable way that the resistor blowing could take out the tweeter with it? Emotiva still suggests the amp is fine -

The blown resistor in the crossover is not in itself indicative of an amp failure,but the smoke emitted certainly indicates some component(s)(resistor in the output section?) was stressed beyond it's rating,if only briefly not causing fatal failure.

Just curious Bluefox Emo must have acted this way before by the accusation you just hurled..?

That's because the function of the "Similar Threads" box is to show...ahem...similar threads. If you will notice the dates posted, they have been over several years time and will likely find similar questions crop up from time to time on every manufacturer's forums."Some people find it easier to be conceited rather than correct."

maybe I was quick enough in shutting the amp off before it caused permanent damage /shrug -
I did not notice the dates..nor did I look for them.
Agreed All manufactures have a Trouble Shooting Forum.
I was just curious as to why Bluefox would think that Emo would Secretly/ Decieve their customer and fix it, they are not immune to failure nor is any other company.That's because the function of the "Similar Threads" box is to show...ahem...similar threads.

Regardless of what they might have done in the past or not, they most certainly do not do that now as there are multiple threads about problems and criticisms on the forums.
Why are you defending such a blanket statement like that, when you know it was wrong to post.For the same reason they remove posts/threads concerning problems or criticism of their products from their forum.ATC SCM40's,VTL TL 2.5 Preamp,PSB Stratus Goldi's,McCormack DNA 500,McCormack MAP-1 Preamp,Pro-Ject Xtension 10 TT,Ortofon Cadenza Red/Nordost RedDawn LS Speaker cables, Bryston BDP-2, Bryston BDA-2,PS Audio AC-3 power cables -

That they are deceptive regarding repairs or scrutinzing their fourm?It's a well known fact. -
In other news It looks like I am going to take the plunge since I have the speaker apart anyways to upgrade both the woofer and crossovers.
what a project this is turning into haha
edit: and to be clear im not doing that myself, looking at vr3mods right now -
