Short answer: the Harman Kardon Onyx Studio 7 if sound quality matters most, the Zealot S95 if price matters most. The Harman Kardon Onyx Studio 7 ranks #12 of 73 boombox speakers at $298.90. The Zealot S95 ranks #24 at $159.41, $139.49 cheaper.
What the Harman Kardon Onyx Studio 7 offers: Warm sound with boosted bass. Watch for: Sounds a little sterile. 8 hour battery at medium volume, teeny bit less bass than the Onyx 6. Not at loud as others. No water rating.
What the Zealot S95 offers: A good value for the boombox class. Appears to be the same internals as the ZE01. Bigger case and goes deeper than the ZE01 Watch for: A little rolled off up top and not that balanced through the rest of the range. Clarity isn’t as good as better speakers.
Buy the Harman Kardon Onyx Studio 7 if sound quality is the priority over the price, or the Zealot S95 if the price is the priority over sound quality.
If water resistance matters to you, the Zealot S95 at IPX6 (powerful water jets) holds up far better than the Harman Kardon Onyx Studio 7 at no water resistance.
