Sony ULT Field 7 vs Soundboks 4
Buy the Sony ULT Field 7 for a portable all-rounder: it is smaller, lighter, has a karaoke mic input, built-in lighting and full IP67 protection, and it costs far less. Buy the Soundboks 4 if raw volume and stage-ready inputs matter more than portability: it hits 126 dB with dual 10-inch woofers and takes XLR and TRS gear. The Soundboks 4 is the louder, tougher-connector speaker, but it weighs 35.5 lbs and costs several times the Sony.
