It's either an excess of glue or some dewd on the assembly like splooged into the port.

I have to admit, Onkyo makes some damned sexy subs.

New and improved goop? Likely a feature. When my software doesn't work as intended, I try to convince people it's a feature

It's Onkyo's trade secret, Chinese secret sauce. Be careful not to touch it, taste it, breathe it, or allow even 1 part per million to escape into the air. Better get yourself a hazmat suit.

I'm just a caveman. Your modern world frightens and confuses me.

Maybe that's all that's left of Onkyo, the company

It looks like a glue they used to minimize vibration of certain components, the PCB, and the leads through the chassis. Pretty common for amps inside speakers where they are exposed to high-pressure sound waves. I wouldn't worry about it. Some things you shouldn't open up, don't want to know, I see nothink...

you may have voided warranty by opening it, tread carefully & read the documents before taking it back & admitting you opened it

definitely doesn't look right though.

to quote DonH50 "It looks like a glue they used to minimize vibration of certain components, the PCB, and the leads through the chassis. Pretty common for amps inside speakers where they are exposed to high-pressure sound waves."



Don is right, it is to minimize vibration. Some high end speakers, like Sonus Faber, encapsulate the entire crossover for this same reason.

It's the new Audio Virus. It spreads quickly and can infect all the electronics in your home. The only known antidote is to close up the sub, never open it again and learn your lesson from it.

I agree with you. The glue is there for a good reason. However, this is an example of a poor workmanship and does not instill confidence in Chinese manufacturing processes.

Oh my imagine what would happen if that virus spreads to all your electronics! Close it up quick!!

Yea should not hurt anything but just sloppy build and installation. I suppose too much of that goop could easily cause overheating though.

Think I would send the pictures to Onkyo.
