The PodXtreme Sound Box claims to have a secret resonator (Ooh!) that gives this little speaker a great big sound. It's powered by a built-in rechargeable Lithium ion battery which sucks power via USB or mains. Supposedly it functions the "same way as a quality subwoofer", which seems like a suspiciously good deal at $29.95. (But it would be totally worth it if it did create "rich, powerful, party casing sound." I always wanted to case rich parties courtesy of a dingdong in my pocket.)
