so my wife just texted me from home ....honey don't get mad, I was just listening to some music ( not overly loud) then I could smell a kind of electrical burning from one of your new speakers.... I look at the message again and think...maybe this is a joke..but no. I just completed some new Mini Statements ( about 2 months old) , assembled with pre made cross overs from Meniscus and driving them with an Emotiva XPA 2. I get home in 5 minutes ( usually takes me 20) and have a short time to check them before having to be back at work. Cannot smell any burning smell from the ports/ drivers. I turned them on and they sound OK, all drivers OK...couldn't conduct any precise listening checks. Will check them over tonight when I can...anything I should look for? Im sure my wife would greatly appreciate any advice!!!!

I had a pair of speakers once where an incorrectly wired impedance circuit caught fire inside the speaker and cooked a resistor. After it had cooked itself and stopped burning, later I really couldn't smell anything either. But a look inside showed black score marks on the inside of the cabinet where the resistor lay black beside it.
I would say the only way to be sure and put your mind to rest is to take a look inside. Not saying what happened to me happened to you. But a visual check is probably the only solid proof that confirms everything is OK.Seek out and destroy early high gain room reflections- Bottom

The only other thing that occurs to me is to check for DC offset on the amp- this can be a problem for speakers, but usually manifests much more disastrously!the AudioWorx

I really hope so!! or she may be sleeping on the sofa!....I'll take the drivers out and take a look at the cross overs when I get home this evening. Not the easiest as the cross overs are in a lower section of the cabs, but I stuck them on with super strong Velcro so may be able to at least see if I can see any burning...- Bottom

Is he sending a matching one for the other channel as well? How much power (amp power) are you running? What are the midranges power rating? Are you sure the crossover is crossing over the mids at a high enough frequency and at a steep enough slope?Seek out and destroy early high gain room reflections- Bottom

Well, I'm not Jon but John and have had two speakers destroyed by DC at the output of two different amps. You can measure DC offset at the output of the amplifier with a volt meter. With the amp turned on put the test leads of the volt meter or multi-meter on the amp output. The DC should be in less than 0.1 volt. I've measured about 45mV at the output of properly working amps.
Sounds like you've found the problem but best to check out the amps to be sure, that it's not just an under rated resistor.

Just noticed if you zoom in on the cap in my picture it's value is 9.1uF, then checked the wiring diagram for the mini statements mid and that cap should 5.6uF so think i have the wrong value cap in there....what will this do to the mid sound? I got the x overs per wired in kit form.- Bottom

Thanks Jim, I thought the speakers sounded good with the wrong crossover, once I get the right one in there hopefully ill notice a difference. Just wondered if it will just be noticeable in the mids or whether the whole sound will change.- Bottom

One would have to look at what that cap was doing in the crossover design (look at the entire crossover design) to make guesses on what will change.Seek out and destroy early high gain room reflections- Bottom
