fred • 12/17/2019, 2:17:43 PM How do I order a new power supply
Customer Service • 12/17/2019, 2:17:43 PM
Hi Fred:Contact our customer service at 1 (562) 697-2600. I believe we have replacements in our RMA returns department. Multiple Bluetooth Speakers use this same power supply.TL/5633
J C • 12/17/2019, 2:17:43 PM How much wire is provided to space the 2 speakers apart?
Customer Service • 12/17/2019, 2:17:43 PM
Hi JC:The speaker wire provided is 25 to 30 feet. Typically we recommend 8 to 12 feet apart for best stereo separation. The extra wire is just in case you need to be creative when hiding the speaker cable between the master and satellite speaker.TL/5643
Jared • 01/16/2021, 1:08:28 PM How much distance in wiring is there between the master speaker and the satellite speaker?
Customer Service • 02/03/2021, 7:08:47 PM
Hi Jared: The unit comes packed with 15 feet. I believe the Master speaker is the left channel and the satellite is the right channel. If your prime listening area is 8 to 10 feet away, that is roughly the distance you want to space the two speakers. You have an extra wire if you need to route the wire in and around obstacles preventing it from running in a straight line between the two. Ideally, the music should appear to come from the center point between the two speakers when listening. TL 2-3-2021
Ronnie Jones • 03/05/2021, 7:51:28 AM how many speakers can be paired
Customer Service • 03/08/2021, 12:05:16 PM
Hi Ronnie: The BTR150 comes as a stereo (R & R&L) pair of Rock speakers, with one channel being the master rock with a Bluetooth Receiver and two (2) channel stereo amplifiers built-in. You have an external power supply (25') cord that needs to connect to an AC Outlet. The kit comes with a speaker wire, so you connect the Master to the second rock that is a passive speaker. It is a closed system, so you are limited to the two speakers. Checkout the BOM4.1.2, an 8" Subwoofer enclosure with a built-in Bluetooth Receiver, 100Watt Mono Sub amp, and a pair of 60 Watts per channel stereo amplifiers. The amplifiers are rated at 4 ohms so that you can power one or two pairs of matching speakers. Technically you could drive two to four pairs of the RX550 speakers from the BOM4.1.2. All that plus the 8" Subwoofer makes for an interesting and affordable outdoor sub-sat system. It is currently out of stock but due in by the end of April, just in time for the summer season.

Floyd • 04/17/2021, 9:03:35 AM Will the speakers have issues with a Bluetooth transmitter that uses aptX low latency audio codec?
Customer Service • 04/29/2021, 12:05:02 PM
Hi Floyd: My understanding is Bluetooth is totally backwards compatible. Ours were all V3.0 but will be getting updated to version 5.0. There has been a shortage on the new chips. I have not heard of any issues with latency so far. TimL/4-29
