Pros: Cleaner sound and a wider stereo soundstage than the Zealot ZE41, with less distortion at high volume for better instrumental detail and clarity.

Cons: The Zealot ZE41 still wins on raw bass depth and price. Large and heavy like the rest of the boombox class, and clarity still isn’t up to dedicated hi-fi speakers.

How it compares: Just above it: Harman Kardon Onyx Studio 9 - $109 cheaper. Just below it: Zealot ZE41 - $6 cheaper.
