JBL EON ONE Compact Rechargeable Portable PA SpeakerThe JBL EON ONE Compact is a PA so portable, youre ready to rock at any moment. Though you can carry it in one hand, its sound is big enough to fill the room. The system produces 112 decibels of rich, crystal clear sound across its entire frequency range, offering uncompressed bass even at high output levels. An 8 woofer extends the low end response to 37. 5Hz, almost an octave lower than comparable PAs. Four channel digital mixer on the EON ONE
