Awful Smell From My Amazings

Was checking out my surround system today. Put in the movie Polar Express. At the beginning of this movie the train pulls up at the kids house. Might have had it up at bit to loud. Anyway the grills on my amazings started to billow out and the meters on my silver 9t's were banging against the maximum side of the amps. Hit the volume button once I realized what was happening but suddenly this awful smell filled the room. When I checked at the back of the speakers I could small this burnt odor. Wonder what I cooked. They seem to be still working. Could it have been the crossover. One other time when I had too much bass energy The leads inside the woofers came together and created a short. The crossover then heated up and smelled terrible. The difference was they didn't seperate the first time and they shut down the woofers. This time all the woofers seem to be active. Maybe the wires just came together when that particular sequence in the movie took place and the woofers were really moving forward. If I take them apart what should I check for??? Never thought I could get enough bass energy to have that happen. Art.

Re: Awful Smell From My Amazings

Art, disassemble the speaker from rear to front and inspect the crossover. You should have some sort of residue either on the board itself or from the capacitor(s) or the bigger resistor. Post a photo of your findings, please.

Re: Awful Smell From My Amazings

I'm guessing the crossover caps. Take the back off and look to see if there is electrolyte spilled (needs to be cleaned up and caps replaced). Was the smell musty? Any smoke?
It should sound like it isn't there!

Re: Awful Smell From My Amazings

Got he backs off. Surprisingly I can't see anything burnt or blackened. Maybe I got lucky and they just heated up enough to stink. I stilll wonder if the two leads from the bass speakers came together just long eough to cause a short and heat up the crossovers. The honeycomb front of the woofers must have really come forward if I noticed the grillcloth billowing out. Think its time for me to get a good sub.

Re: Awful Smell From My Amazings

Art...WTF?!? Who were you trying to impress this time? :lol:

I'd check the impedance also; if you burned any section of the voice coil, it will lower your impedance, possibly dangerously (for the amps).

Re: Awful Smell From My Amazings

I fed my pair of Amazings Plats with bi-amping setup with Technics SE-A3 on the low end and Denon POA-3000 on the ribbons. I think I was testing the pre (Aragon Aurum) at that time so I played Hotel California on repeat.

For some reasons, I got a sudden urge to see how my amps can handle the Plats. I cranked and cranked and cranked more. No sweat for my amps. But when the needle hits 200W (8 ohms readings) on the meter of SE-A3, I heard fart fart fart from one of the speakers. I immediately turned off the volume and looked at my plat. Sure enough, one speaker got a damaged woofer from over excursion. Damn, there goes my $50 bucks. #-o

Another one of Amazing story to brighten the OP day! As others suggested, take a look at the XO and check the resistance of the ribbon and woofers.

Good Luck fixing it!

Re: Awful Smell From My Amazings

How do you check the resistance of the ribbon and woofers.???????????????

Re: Awful Smell From My Amazings

I just unsoldered the wires leading to the speaker woofers and ribbon assembly at the crossover and measured from there. Do you remember what ohm rating you are looking for?

Re: Awful Smell From My Amazings

You can do a preliminary impedance check AT THE TERMINAL CONNECTORS.

You should get around 4-5 ohms resistance. If it's lower, you've probably burned a voice coil. If higher, it's possible you've opened a circuit in one of the crossover caps. You can go from there, but that will give you at least an indicator. Post back what you find at the terminals connectors.

Before you go tearing your stuff up - 8-[

Last week I had the same problem with my great BOSE speakers. I panicked until I realized my Bride had farted near the bass tube.
