Bought a Boss Elite 8" subwoofer from SonicElectronix.com which was sold as new.
This speaker was DEAD right out of the box.
My multimeter read 0 ohms on the terminals
Rather than suffering the time and aggravation of dealing with customer service again I decided to carefully dismantle the speaker and see what was wrong... when I removed the dust cap from the center of the cone I was shocked to see dust and grit all around the area of the coil cylinder... this debris was not caused by my cutting through the hard plastic dust cap with a razor knife... it was obviously there when the speaker was assembled. This area of any speaker must be completely free of any kind of dust or debris in order for it to play correctly and for it to last... I could smell a burned odor from around the coil area and when working the cone up and down I could feel a scrubbing in the cylinder action... this speaker was sold as new and was dead on arrival... if you want to understand what I'm saying here you can go to YouTube and search... Rebuilding a subwoofer... and see how they're constructed... My guess is that due to a careless mass production of these cheap speakers is that time is more important than quality... I'm really shocked at what I've found... The cylinder area of a speaker works up and down with every pulse of sound and should be perfectly clean... I can see scrub marks on the inside of the sleeve that works up and down around the coils... I am really disappointed in what I have found and now I'm thinking about the saying ( You get what you pay for) Wow... I would have never expected this from any speaker manufacturer...
