LG features twice in this edition of the column with two very different but similarly strange speakers. The "Levitating Portable Speaker" has as descriptive and accurate a name as the "Small Transparent Speaker" from last month's edition of this column. You can call it "PJ9" if you prefer the duller moniker. Yes, through the magic of electromagnets and a base station, this speaker will levitate and pump out audio in every direction. LG's Dual Passive Radiator system is designed to provide strong high- and mid-range tones.
