The indoor/outdoor Rocketfish RF-WS02 wireless speaker features a built-in class D amp with 20 watts of power to give you everything you need in one small package. Inside the RF-WS02 is a five inch driver speaker and a two inch tweeter. Twenty watts of power is on the higher end of most wireless speakers in this class and the sound you get as a result is very enjoyable.
You have the option of running the RF-WS02 using 8 C batteries or the included AC adapter. If you opt to use batteries you can take advantage of a unique option on the Rocketfish speakers. Inside the battery compartment is a switch that can be set to alkaline or NiMH if you have rechargeable batteries loaded. If you set it to NiMH the speaker will actually charge the batteries for you when it is plugged in. Just be careful not to make the wrong selection if you have non-rechargeable alkaline batteries loaded or you could cause damage to the speaker or the batteries. If the speaker is set to NiMH there is an LED light that will indicate the charging status of the batteries. It will flash green if it is in the process of charging and will stay solid if charging is complete. In order to help battery life, the speakers will automatically shut off after five minutes if they are not receiving any audio signals.
The speaker has a water resistant futuristic cylindrical shape and the antennas are hidden inside the enclosure to add to the stylish look. There are controls on the speaker for volume and to turn the bass boost option on or off. You have options for how you want to use the speaker because it provides a left-right-mono selector which depends on how you are using it. If you use it in tandem with another RF-WS02 then you select left or right, otherwise the mono setting is where you’ll need to set it. Other cosmetic features you will find are additional LED lights for the power, pairing status, and bass boost status. As is the case with most Rocketfish wireless speakers the speaker should be pre-paired at the factory so that they are automatically communicating with the sender unit as soon as you power them up. If for some reason that isn’t working, there is a manual pairing button located on the back of the speaker as well as the sender unit.
The sender unit (transmitter) for the system operates at a 2.4 GHZ wireless frequency which is a common frequency these days. Most wireless computer networks and cordless phones also operate in that band. You connect the sender unit to your sound system using a run of the mill RCA cable. The transmitter is powered by a standard AC adapter and has a link LED that indicates whether it is paired up with a speaker or not.
