Alpatronix C3 Ultra-Portable Mini Capsule Speaker with Enhanced Bass & 3.5mm Audio Jack for Apple iPhone, iPad, iPod, Samsung Galaxy, Nexus, HTC, Blackberry, Nokia, Smartphones, MP3/MP4 Players, Tablet, PC, Laptop [SONPRE EDITION] - (Black)
this speaker puts out some bass.  I use it with my mp3 player and laptop and i can hear it throughout the house.  It has a very handy little recharging cable too. It has usb on one end that connects to an ac adapter as well and on the other end it splits into an aux plug and the connection plug (like on the bottom of cell phone).  conveniently i can use this handy cord for other devices.
