Everybody talks about the best stuff. Nobody ever talks about the worst. We,, here's your chance! Only caveat? It's in the question. It's gotta be in the last decade. If it was all-time it's too open. Leaves too much to the imagination and can often be hard to quantify because one person might have heard the speaker but others didn't.
Of course there are the knee-jerk responses like Bose or calling out entire manufacturers like modern KLH, a Taiwanese conglomerate, a mere shell of it's past glory. That's all well and good but there has to be a speaker you heard somewhere that just reminded you of goats farting in a church. Well, time to name names! Let's hear it! What's the worst speaker you've heard from 2000-2009?
Me? It has to be the Sony Xplod Mobile ES speakers. Specifically the 6.5" coaxials. Back in the mid-90's Sony Mobile ES was the bees knees and major bang for your buck. It was Sony flexing their engineering muscle. Then they cheaped out and went for the Xplod series which was dog poo. Not too long ago, Sony announced that they were switching gears and getting back to quality stuff instead of quantity stuff. They announced the Xplod ES series. I was intrigued. Then the warning signs came up...only sold in BestBuy. That ended up not being true but it was a huge red flag. I went and listened anyway. I gave them the benefit of the doubt because of the installation location but I was so sorely disappointed. Such potential and it wasn't any better than the entry level Dual crap next to it but almost 3 times as much. Very sad.
