FL-B003 Dual Passive Radiator Bluetooth Speaker IPX5
97 x 76 x 32mm, 3.5W, passive radiators either side for bass
FL-B003 uses two passive radiators to get low end out of a body only 97 x 76 x 32mm. A passive radiator moves with the air the driver pushes, which is how a pocket speaker produces bass it has no room for.
The unit runs 3.5W on an Actions V4.2 + EDR chipset from a 1200mAh cell, and is rated IPX5 against spray.
What This Model Does Better
Dual passive radiators
Real low end from a pocket-sized enclosure, not an equaliser trick.

Spray and rain resistant, so the speaker can live outdoors.
1200mAh in a 97mm body
A long session from a unit that fits a coat pocket.
Bluetooth 4.2 + EDR
A stable modern link with low idle drain.
