Stormeo • 12/17/2019, 2:17:43 PM What does B-stock mean?
Customer Service • 12/17/2019, 2:17:43 PM
Hello, B-Stock refers to an item that is either pre-owned, refurbished, scratch & dent or open box.
tony • 12/17/2019, 2:17:43 PM Is it normal for some rain/water to get inside of the speaker?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Tony: It really depends on the speaker placement. You need to stay away from Sprinklers or potential standing water. And it is a good idea to bring these in for the winter months. All access points are protected with liberal application of silicon. But the perforated grill over the speaker will let water to the front of the Cone and surround which are waterproof. But if water accumulates at the bottom of the speaker for any length of time especially during the off season it an cause problems (that is why we recommend bringing them in during Winter months).

DAN GEORGE • 12/17/2019, 2:17:43 PM What is the wattage of this model and when can I expect availability?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Dan: This should be in stock next month; the power rating is the same as the Bluetooth Frog speaker; 2 x 10 watts. TL/4687
Michael Gilligan • 12/17/2019, 2:17:43 PM Are these true wireless speakers or are there connections and power supply?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Michael: Good question, in fact, the only thing wireless is the connection from your Bluetooth enabled device and the Master Rock speaker which features a Bluetooth Receiver and 2 channel Stereo power amplifier which you have to run an AC power supply to the Master Rock with the external waterproof power supply that comes with the kit. But you are not done yet, then you have to connect the Satellite Rock Speaker to the Master Rock using the speaker wire that is supplied with the kit as well. I hope that answers your question TL/5090
