Comparison REL T/9i vs REL T9

The presence of a wireless connection in a subwoofer is most often Bluetooth: this standard is practically generally accepted in modern electronics, it is supported by the vast majority of smartphones, tablets and laptops. Note that we can talk about connecting an audio signal, as well as connecting to a device like a smartphone or tablet to manage settings. However, the latter option is not common — mainly in concert models, based on the ability to reconfigure the subwoofer even in a situation where there is no direct access to it.

If we talk about wireless sound transmission, then this option is convenient primarily from the point of view of choosing the optimal installation location: moving the subwoofer around the room, you do not need to mess with wires, and the Bluetooth range reaches 10 m. However, the quality of sound transmission with a wireless connection may be lower than with wired, but for bass this point is not as noticeable as for other frequency bands.
