Like new JBL Eon One has Bluetooth functionality, RCA, XLR, 2 channels, and monitor. Has 3 columns that attach and extend up. You can use one, two or all 3 depending. The speaker comes with a super cool roller base for ease of movement with a cover that clips on the base at each corner and covers the entire speaker. Easy to pack and transport. Offers big, clear sound for outdoor parties and events. Selling with some hesitation but need to move on from a floor speaker. Love JBL and the sound and ease of this speaker for a variety of events. Specs are 400 wide x 540 length x 670 tall with stand. Each speaker tower section 500 long so 1500 total. Height in total is 2170. Has not been used hard.
