The Logitech S715i's excellent bass response is helped by two rear-firing passive radiators. Connections for aux input and power adapter are also included on the back, as well as an integrated kickstand.
A total of three drivers are placed on each wing of the Logitech S715i, not including the two passive radiators mounted on the back. By utilizing frequency crossovers and a tuned enclosure, the Logitech S715i delivers fantastic sound for the money.
Compared with previous portable speakers from Logitech, the S715i is the largest and most powerful portable systems we've tested. Inspite of its relatively large size, it's still slim enough to fit in a backpack or messenger bag.
