*Typical specs for this NDR model:* - *Drivers*: 2x 8" or 10" woofers + tweeters = heavy bass - *Output*: Usually 120W - 300W RMS depending on exact model - *Battery*: 4-8 hours at 50% volume. Has AC power input too since I see the cable on top - *Features*: Bluetooth, USB, SD card, FM radio, mic/guitar input, LED light modes - *Design*: Handle on top + wheels sometimes, but this one looks carry-style
