Q. Can The Speakers Be Left Out All Year?

A. They are weather resistant so can be left out all year round, however we do recommend bringing them in for winter if possible.


Q. Is The Amplifier Waterproof?

A. No, the amplifier must be installed indoors in a dry location. Alternatively you can mount it in a suitably IP rated plastic external enclosure.


Q. How Far Away Can The Amplifier Be From The Speakers?

A. You need to keep the amplifier as close to the speakers as possible, mostly because it is Bluetooth and the range for Bluetooth is approx 8-10 metres so we always suggest keeping the amplifier as close to the listening position as possible.
