A:Answer Thank you for your inquiry. For a 50x100 room, our JBL Flip 5 is great for "personal" background music in one corner, but it won't "fill" the room for a party or event. For a room that large, we recommend a more powerful unit, like the JBL Boombox 4 or the JBL PartyBox Club 120. These models are designed to deliver high volume and deep bass needed to cover large areas and keep an event lively.
