You might have seen that I blew one of my Amphion tweeters (at first) along with my amp…made sure it was the speaker by plugging into other channel with same results: no tweeter. But I hooked everything up again the other day and now I’m getting nothing from my left speaker…
I just got the replacement tweeter in today, but now I’m suspecting it’s something bigger than the tweeter. But I’ll need that new tweeter because I fucked it up trying to pull it out. (Dented the cone)…sigh.
So my question is this: should I just find someone to work on this thing? I would assume putting in a new tweeter won’t make the woofer work again lol. I should wait, right?
Anyone remember my first attempt at a wooden diffuser I. Around 2014?

I’ve replaced the Amphion woofer, tweeter and rear passive radiator. None were exceptionally difficult.
Sounds like you might be in the troubleshooting amp phase, though.

Makes me wonder what happened to blow the tweet..

Nashville Speaker repair is on Facebook talk to them full service including recone so they know speakers unlike typical electronics tech. I know they do both SR and JL audio car stuff so I’m sure the Amphions should be no problem.
Otherwise try some wire directly from the working amp ch to the woofer. You will then know if the woofer is bad or if its wire harness or something burned up in the x-over.
The other thing you could try is this if you had a multi meter is call Amphion and see what the resistance of the woofer should be and take a quick measurement, you could also ask if they have someone they recommend for service.
If you don’t feel up to either maybe make an offer of any local member who knows how to do either gets a free T shirt for coming over and checking the woofer.

Damn man…you’re having a string of bad luck…time to hit the casino and turn it around! What amp are you using again?

From what I found on line the voice coil resistance should be about 5.6 ohms so anyone with a VOM in Nashville and knows how to use do JK a solid!

I do have a multimeter somewhere...but you'd have to explain it to me like a 5 year old. It’s actually pretty simple, set the meter to measure ohms, if it has a range switch set it to its lowest range. Disconnect any wires from the woofer then touch one probe to each of the woofer’s terminals, +- doesn’t matter, if the coil is good it should measure approximately 5.6 ohms. One of the easiest and least dangerous uses of VOM! |

Woofer measured @6.0 That should be good, but I would call Amphion and double check since there is an Amphion suffer on the driver’s model #, my hunch is is a stock version that Amphion QC’s but they might be a more custom version. |

I'll report back about what's happening...but they're working!
