Sony XS-FB101E 10cm Dual Cone Car Speaker, 210W Peak

Our review

This is a compact 10cm (4-inch) Sony speaker built around a dual cone layout, with an aramid carbon fibre matrix woofer and a quoted frequency range of 45–23,000Hz. Power figures are worth reading carefully: 210W is peak, while CEA and rated power sit at 30W, so it is best matched to a head unit or small amplifier delivering roughly that continuous range rather than a big dedicated amp. It suits drivers replacing tired factory speakers in a small car, or anyone wanting clearer vocals and fuller bass from a modest setup. Before buying, measure your existing speaker mounts and confirm the 10cm size fits, and check the depth behind the door or parcel shelf. Compared with basic single-cone speakers of the same size, the dual cone design and aramid woofer are the main points of difference; compared with component sets, you give up a separate tweeter but gain simpler installation. Available on Sokonia.
