The JBL PartyBox Stage 320 already crushes most of its competition when it comes to portable party speakers that can actually fill a space with serious sound, and now it’s dropped to $449 on Amazon which is a record low from its usual $599 price tag. This beast combines two 6.5-inch woofers with dual dome tweeters to pump out enough volume to energize a tennis court-sized area, while its telescopic handle and rugged wheels let you roll it wherever the party calls. You’re getting a legitimate pro-grade speaker system that doesn’t need an outlet to keep the music pumping for up to 18 hours straight, plus it looks incredible doing it with synchronized light effects that react to your playlist.

Built-In Show That Goes Beyond Basic Bluetooth
The PartyBox Stage 320 doesn’t just play music but it also turns rooms into real event spaces: The two 6.5-inch woofers give you clean bass even when you turn the volume all the way up. The 25mm tweeters, on the other hand, handle high frequencies with a level of accuracy that most portable speakers can’t match. You can connect your phone via Bluetooth, plug it in through the aux input, or use the USB port to play music directly from a drive.
The built-in light show has starry patterns, trailing light effects, and strobes that sync up with the beat of your music. These lights change and pulse with the beat and intensity of the music which make the space feel more like a club than a backyard. With an IPX4 splash-proof rating, you can set this up by the pool or on the beach without worrying about water splashing on it or a light rain starting.
This speaker has a replaceable power pack that gives it an 18-hour battery life: This is different from other speakers that die after a few years when their sealed batteries wear out. You don’t have to buy a new speaker when you need a new battery; you just change it out. A 10-minute quick charge gives you two more hours of battery life, so even if you forget to plug it in overnight, you can still get it ready for an event in the afternoon.
You’re saving here $150 on a speaker that was already a great deal at full price.Speakers that are this powerful and have this many features usually cost more, and the ones that do have this much power don’t usually have lights, battery swapping, or professional audio inputs. This price drop makes it a no-brainer for anyone who hosts events or needs serious sound for events.
