About the OSD BTP-650

Archer A.

Outdoor speakers with a wireless twist

Usually, installing outdoor speakers involves long runs of speaker wire to a receiver or amplifier that stays indoors. But OSD's BTP-650 is a forward-thinking option that makes it easier to enjoy great sound outside. And you don't even need a receiver to make it happen. These Bluetooth-enabled outdoor speakers are great for pools, covered patios, decks, and more, and they're easy to install and start playing.

Outdoor speakers with a wireless twist

Usually, installing outdoor speakers involves long runs of speaker wire to a receiver or amplifier that stays indoors. But OSD's BTP-650 is a forward-thinking option that makes it easier to enjoy great sound outside. And you don't even need a receiver to make it happen. These Bluetooth-enabled outdoor speakers are great for pools, covered patios, decks, and more, and they're easy to install and start playing.

Built-in Bluetooth for easy streaming and setup

The BTP-650s have Bluetooth built in for easy access to music from your compatible phone, tablet, or laptop.  The "main" speaker houses the amplifier and Bluetooth module. It connects to an outdoor AC outlet with the included water-resistant power supply. The second speaker is completely passive and connects to the main speaker with an included run of speaker wire.

Weather-resistant enclosure with potent drivers

These speakers feature rugged composite resin cabinets, meaning they're durable enough to crank out tunes year-round, rain or shine. Their rust-proof aluminum grilles protect the drivers from any bumps and bangs that might occur during installation or afterward. If you live in a salty environment, OSD recommends spraying the grilles with clear coat for maximum protection against corrosion.

Each speaker has a punchy 6-1/2" polypropylene woofer that deals out tight bass. Above the woofer is a 1" silk dome tweeter for smooth, clear highs.

Versatile mounting bracket

These speakers come with unique mounting brackets that give you perfect positioning even in less-than-ideal spots. OSD recommends installing the speakers under a covered area for maximum longevity.

Product Research


Weather Resistant Enclosure (IP54): The OSD Audio BTP-650 powered outdoor speaker utilizes a composite resin, acoustic suspension (sealed) enclosure that has been silicone sealed, plus a powder-coated rust resistant aluminum grille and mounting bracket to withstand the outdoor elements. The OSD Audio BTP-650 is IP54 rated, meaning it is protected against water spray and dust build-up. The BTP-650 is designed to withstand all types of weather and perform under some of the harshest conditions.

Note: The BTP-650 is weather resistant, but not waterproof. It cannot be submerged in water.

2-Way Powered Speaker: Each loudspeaker houses a 1" silk soft-dome tweeter and a 6.5" polypropylene cone woofer for full-range, outdoor sound (300 to 500 sq/ft) . The main powered speaker includes a built-in 150 watt amplifier that powers the drivers in both speakers for dynamic sound with low distortion. The passive speaker connects to the main powered speaker via spring post terminals and the included 24.5' speaker cable.

  • 1" Silk Dome Tweeter: The OSD Audio BTP-650 features a 1" silk dome tweeter. This silk tweeter material is well suited for outdoor applications because it is made from microscopic iron particles suspended in a non-conducting viscous oil which helps dissipate heat and promotes longevity.
  • 6.5" Polypropylene Cone Woofer: The BTP-650 houses an 6.5" polypropylene cone woofer with rubber surround. Polypropylene is a popular speaker material due to the added stiffness and durability it offers over paper cones. Polypropylene cone woofers produce rich bass and detailed midrange for very balanced sound overall.

Built-In Bluetooth: The OSD Audio BTP-650 powered outdoor speaker features built-in Bluetooth 3.0 with support for wireless audio streaming (A2DP). You'll be able to wirelessly transmit audio from your Bluetooth-enabled smartphone, tablet, laptop, or desktop computer to the outdoor speaker system. You'll still control music playback and view song/artist/album info from your source device (not the speaker). Only one source device can be paired, connected, and used for playback at a time. The rear-panel power switch can be left On, when the speakers are not in use, allowing them to automatically re-connect with the last paired device when back in range. If not using the speaker system for long periods of time, the power switch can be turned Off. The speaker system has a wireless Bluetooth range of approximately 30' to 50'.

Note: The BTP-650 does not offer a wired source input.

Mounting Options: Each speaker comes with its own powder-coated, rust resistant aluminum bracket to mount the speakers on the outside of your home. The brackets allow you to mount the speakers vertically or horizontally. When mounted vertically, the brackets let you swivel the speakers a total of 180 degrees (90 degrees left or right), as well as tilt the speakers a total of 60 degrees (30 degrees up or down). When mounted horizontally, you can swivel the speakers a total of 60 degrees (30 degrees left or right), as well a tilt the speakers a total of 180 degrees (90 degrees left or right). You can also use the mounting brackets to position the speakers vertically or horizontally on a tabletop or other flat surface.

  • Vertical Dimensions: 7.8125" (w) x 11.9375" (h) x 9.625" (d)
  • Horizontal Dimensions: 11.9375" (w) x 7.8125" (h) x 9.625" (d)

Power Requirements: The main powered speaker needs to be located near an AC outlet where you can connect the included power supply to the speaker in order provide the electrical current needed for the built-in amplifier and built-in Bluetooth receiver. The AC power supply features an attached 3.5' cord that plugs into an AC outlet and a 16' cord that plugs into the back of the main powered speaker.

  • When mounting the power supply outdoors, you must use a GFI protected AC outlet with "in-use" waterproof cover.
  • The power supply is IP67-rated and waterproof. As a precaution, try and limit the power supply's exposure to harsh weather, water spray, and other outdoor elements.
  • The AC power supply measures 6.125" (w) x 1.4375" (h) x 2.125" (d).

Customer Q&A

11 questions already asked

do both speakers produce sound when using bluetooth?
[ jeffrey  Mar 02, 2023 ]
1 answer
Yes. Both speakers operate together at all times as long as they are properly connected to one another using speaker wire.
[ ZACHARY  Mar 03, 2023 ]  Staff
Are these speakers weather proof? Could they be placed under the eave and remain outside?
[ JIM  Feb 24, 2023 ]
1 answer
These fantastic OSD BTP-650 speakers can be installed under the eave and permanently mounted outdoors, Jim. The OSD's have an IP54-rated all-weather housing but do need AC power supply for operation. Make sure to mount one speaker close to an electrical outlet, and you are good to go! The second speaker is passive and does need to be physically connected to speaker #1 with traditional speaker wire. These are true performers, with a silky-smooth sound perfect for any musical styles!
[ Bo  Feb 25, 2023 ]  Staff
Do these support SCMS-T (Serial Copy Management System-Transfer) protection? I'm looking to pair these with a projector that lists that as a requirement for connecting via bluetooth.
[ Ben B  Nov 05, 2022 ]
1 answer
None of our Bluetooth speakers will list SCMS-T as a feature sadly, Benjamin. Not knowing the exact model of projector being used will mean my info will be a little vague and I apologize. The SCMS-T feature as I understand it means that there is a copyright protection codec built into your projector that would prohibit it from streaming music specifically that does not have that coding. This most likely will not affect the projector's ability to connect to the speakers, only what you could potentially play on them. The good news here is since there are some questions marks with the connection, you can always return the OSD BTP-650's if they did not connect.
[ Bo  Nov 05, 2022 ]  Staff
Can I connect these speakers via Bluetooth to my turntable, located inside the house?
[ DANIELA  Oct 10, 2022 ]
1 answer
The wireless range for those speakers is up to 50 ft so, as long as your turntable's transmitting the signal within that range, you should be able to pair them together. The closer they are, the better the signal especially if there is a wall between them.
[ ARIELLE H  Oct 10, 2022 ]  Staff
Do these speakers need to be powered on/off every time you use them?
[ MICHAEL  Sep 02, 2022 ]
1 answer
It is only necessary to turn off these speakers during longer periods without use. If they are being used daily, they can be left on.
[ ZACHARY  Sep 02, 2022 ]  Staff
Do they play in stereo or just dual mono?
[ Clint  Feb 18, 2023 ]
1 answer
Greetings Clint, and thank you for your question. The left speaker has the built in stereo amplifier, the right speaker uses wire to connect to the master. It is a stereo left and right set up, not dual mono.
[ THOMAS  Feb 19, 2023 ]  Staff
Is there anything else needed to make these function besides what is included here? (additional receivers, etc.)
[ C  Dec 04, 2022 ]
1 answer
You just need to add your favorite Bluetooth source, Cheryl! These OSD BTP-650 speakers have an amp built into one of the speaker units and they also come with 24.5' of speaker wire to connect the two speakers together. They also come with mounting brackets included, so once you install them and power them up you can pair your smartphone, Bluetooth turntable, TV, whatever Bluetooth source you'd like then listen and enjoy.
[ Bo  Dec 05, 2022 ]  Staff
Would I be able to use these for TV Audio with my outdoor TV essentially like a soundbar type of setup?
[ Garret  Nov 02, 2022 ]
1 answer
These speakers do not have any wired input but if your TV has a bluetooth transmitter then you can link them wirelessly and get your audio that way.
[ ARIELLE H  Nov 03, 2022 ]  Staff
How many watts?
[ Javier  Aug 17, 2022 ]
1 answer
Greetings Javier, and thank you for your question. The OSD BTP-650 has a 150 watt amplifier built into the main speaker that powers it and the secondary speaker as well.
[ THOMAS  Aug 17, 2022 ]  Staff
Installed them and they worked great , a few hours later I couldn't reconnect, kept saying can't connect . Why ??
[ RICHIE  Jul 05, 2022 ]

[ ZACHARY  Jul 05, 2022 ]  Staff
Hi there, do you know if you can connect four of these speakers (two sets) to one audio source?
[ CAMPBELL  Apr 09, 2022 ]
1 answer
Almost certainly not. The only audio input for this speaker set is a Bluetooth receiver, and Bluetooth can only connect to one transmitter at a time. To use two of these speaker sets with one audio source, that source would have to have two Bluetooth transmitters.
[ PATRICK  Apr 11, 2022 ]
