The Two Speakers In Full
JBL Partybox Encore 2: $330 Samsclub eBay
Pros: The Encore 2 improves the original with dome tweeters, a less boomy balance, slightly deeper bass, longer battery life and two included wireless microphones. Its compact karaoke-ready design and 7-band EQ make it more adaptable indoors than the earlier Encore.
Cons: It still lacks some upper-bass punch and cannot match the scale of the larger PartyBoxes. The main value is compact karaoke convenience rather than full-range party output.
