The Universal Stereo Acousticup is a pair of collapsible speaker amplifiers designed to hold your smartphone/tablet and route each speaker output to an adjustable amplifying megaphone. Each speaker deflates to less than an inch tall, but can be instantly popped back to full size. Pop up the left speaker, then the right, pop in your smartphone or tablet, and be amazed at how much louder and cleaner your system will sound. No batteries, no power, no wires, no electronics - just a simple, convenient, pocket sized amplifier. Space in slot for phone + most covers. Perfect for picnics, BBQs, parties anywhere, anytime! No fuss, no muss, no remembering to charge it up. Invented by master Kurt Schmitz at the Dan Murphy Memorial BBQ. Ingenious!
Works with any smartphone or tablet less than 11mm thick. Includes iPhone5, iPhone6, Samsung S3, S4, S5, HTC One, iPad Mini.
To pop open, lay cone edge down, raise back until all segments open, stroke edges to pull tight. For best base results, place in center of Base Bucket (sold separately).
