Eric A.

Wall-mountable outdoor speakers with a convenient wireless touch

OSD's BTP-525 offers a new way 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.

Wall-mountable outdoor speakers with a convenient wireless touch

OSD's BTP-525 offers a new way 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

These speakers 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 5-1/4" woofer for solid bass and midrange. Above the woofer is a 1/2" 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-525 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-525 is IP54 rated, meaning it is protected against water spray and dust build-up. The BTP-525 is designed to withstand all types of weather and perform under some of the harshest conditions.

Note: The BTP-525 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 5.25" polypropylene cone woofer for full-range, outdoor sound (300 to 500 sq/ft) . The main powered speaker includes a built-in 100 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-525 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.
  • 5.25" Polypropylene Cone Woofer: The BTP-525 houses a 5.25" 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-525 powered outdoor speaker features built-in Bluetooth 5.0 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-525 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: 6.520" (w) x 9.963" (h) x 8.162" (d)
  • Horizontal Dimensions: 9.963" (w) x 6.520" (h) x 8.162" (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

7 questions already asked

Can both speakers be hooked to an amp instead of using the Bluetooth function?
benton  May 26, 2023
1 answer
They cannot, Benton. If you need a set of passive speakers (no Bluetooth or amp built-in) I would use the OSD AP850 in the link below. These need a separate amp for use and have no Bluetooth onboard but have the same sound quality and robust build that you would expect from OSD!
bo  May 26, 2023 (Staff)
Can you connect 4 speakers together?
george  Feb 17, 2023
1 answer
Unfortunately, this would not be possible. These speakers are designed to work in a set of two with one Bluetooth source playing.
zachary  Feb 17, 2023 (Staff)
Do these speakers accept a 3.5mm audio cable input or only bluetooth?
lisa  Sep 12, 2022
1 answer
Those OSD speakers are only bluetooth.
arielle h  Sep 12, 2022 (Staff)
I'd let to have 4 of these speakers linked together is that possible?
emanuel  Jan 24, 2023
1 answer
That is a great question. Unfortunately these speakers don't have any inputs or outputs to link them to other components.
arielle h  Jan 25, 2023 (Staff)
can you power with 12v dc?
howle  Aug 22, 2022
1 answer
Greetings Toye, and thank you for your question. The included power transformer converts AC to DC then to the speakers built in amplifier, so technically it runs off DC. We are not going to recommend doing that because you would have to cut the wire off the transformer to connect a 12 volt battery. After that you will have no warranty, or return policy.
thomas  Aug 22, 2022 (Staff)
I'm trying to connect these speakers to an outdoor TV, my TV recognizes it as BT Speaker via Bluetooth but it stalls out when trying to pair with it. Any advice?
eric  Aug 06, 2022
1 answer
If the transmitter in your TV can recognize the speaker but won't connect then perhaps the signal between the two isn't strong enough. If possible, you may want to experiment with the distance between the master speaker and the TV to confirm a solid connection can be made.
arielle h  Aug 07, 2022 (Staff)
do you need to power off after each use ?
thomas  Jul 12, 2022
1 answer
These do not need to be powered off.
