I needed some cheap, small speakers for my desk,
Amazon had a pair of Denons for only 60€ (66$), I just couldn't resist.
My expectations weren't that high, but still, they were crushed immediately:
While the mid-range and base section sounded fine, very surprising for their size, the highs were TERRIBLE.
Take a normal pair of speakers and glue pillows in front of them - that would be the closest I could think of.
Since I'm an electronics engineer I've decided to take them apart and take a peek:
Wait! What?! No crossover?! You gotta be shitting me Denon.
Just and electrolytic capacitor in front of the tweeter, that's all.
An that's not even the end of it: The value was totally off - 2µF - that's a crossover frequency of (I don't know) 8 or 9 KHz.
So I spent some time to design my own crossover network ;)
It was worth it, I'm now able to enjoy music on those speakers, that's why I want to share this project with you guys.
Disclaimer: It isn't pretty, but it get's the job done:
