Short answer: the Harman Kardon Onyx Studio 7. It ranks #14 of 98 boombox speakers by sound quality (rated 4.1/5) at $248.90 and is still sold new; the W-King H10 ranks #75 (rated 2.7/5) and is discontinued, so it is only an option used.
The Harman Kardon Onyx Studio 7 is the better-sounding, deeper-bass choice. The addition of dual tweeters gives the Studio 7 a wider, more spacious presentation than older Onyx models. Its bass reaches about 37Hz before falling 10dB, against 54Hz for the W-King H10. It links with other speakers (Wireless Dual Sound), which the W-King H10 cannot. The tradeoff: Consumer Reports finds the bass prominent and boomy, mids hazy, treble slightly smeared and the soundstage congested.
The W-King H10 is the louder, longer-running pick. Comes with wireless microphone. Alan Ross Reviews measured it at 115dB at full volume, against 96dB for the Harman Kardon Onyx Studio 7. It is rated for 24 hours of battery against 8 for the Harman Kardon Onyx Studio 7. It is rated IPX6, while the Harman Kardon Onyx Studio 7 has no water resistance. The tradeoff: Not very deep bass.
Buy the Harman Kardon Onyx Studio 7. It is rated higher for sound quality, and the W-King H10 is discontinued, so it is only available used.
