Features

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

16 questions already asked

Q
Can these be run from 120V instead of using the power lead?
dan  Apr 12, 2025
1 answer
A
Greetings Dan. Thank you for your question. Crutchfield is not going to recommend using anything other than the included power supply. If you wanted to hard wire these, you might want to run it past the manufacture. Their number is 888-779-4968.
thomas  Apr 12, 2025 (Staff)
Q
Are you able to use these with your outdoor TV Especially if it is a smart TV ??
terry  Jan 25, 2024
1 answer
A
If your outdoor TV offers Bluetooth transmission capability, then it should be possible to wirelessly connect the TV to the speakers. However, there is no guarantee that there may not be some amount of latency issues where the audio may lag behind the video.
zachary  Jan 26, 2024 (Staff)
Q
is there a volume control for the built in amp or is it at a preset level ?
frank  Jan 09, 2024
1 answer
A
There is no volume control on the OSD BTP-525 outdoor speakers, Frank. Volume will be controlled by your connected Bluetooth device.
bo  Jan 09, 2024 (Staff)
Q
Can you buy longer wires to get the speakers further apart?
brent  Dec 13, 2023
1 answer
A
Greetings Brent. Thank you for your question. Both speakers have spring terminals that can take any speaker wire. Preferably wire that have extra shielding for moisture protection as well as UV ray protection.
thomas  Dec 13, 2023 (Staff)
Q
How do you power this unit on and off, is there a remote?
e  Jul 16, 2023
1 answer
A
Thank you for your question E Torres. There isn't a remote control that comes with these speakers, your phone or tablet will be used to control the speakers. 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'.
andrea  Jul 16, 2023 (Staff)
Q
Can both speakers be hooked to an amp instead of using the Bluetooth function?
benton  May 26, 2023
1 answer
A
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! https://www.crutchfield.com/p_452AP850B/OSD-AP850-Black.html
bo  May 26, 2023 (Staff)
Q
Can you connect 4 speakers together?
george  Feb 17, 2023
1 answer
A
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)
Q
Do these speakers accept a 3.5mm audio cable input or only bluetooth?
lisa  Sep 12, 2022
1 answer
A
Those OSD speakers are only bluetooth.
arielle  Sep 12, 2022 (Staff)
Q
Do these speakers play in stereo?
joseph  Feb 22, 2025
1 answer
A
These speakers will produce a stereo sound with the left channel audio coming from one of them and the right channel audio coming from the other speaker
jason  Feb 22, 2025 (Staff)
Q
Can I use these speakers with A/V R?
michele  Oct 19, 2024
1 answer
A
Hey Michele, so these speakers are not something to be utilized with an AV Receiver. These are powered bluetooth speakers that are just designed to go outside so you can wirelessly play music from your phone to. We have advisors who can be reached by calling 1-800-324-9695 that can help recommend the best speaker for your goals.
red  Oct 19, 2024 (Staff)
Q
Can these speakers be hardwired, bypassing the bluetooth?
kevin  Apr 09, 2024
1 answer
A
Greetings Kevin. Thank you for your question. Nothing is impossible, but this will be close to that. The amplifier input to one of these is hardwired, and the output terminals are to run to the second passive speaker. If you take apart the master speaker, you could technically connect speaker wires to the speaker from another amplifier, but at that point, why not just buy outdoor passive speakers.
thomas  Apr 09, 2024 (Staff)
Q
If these speakers do not need to be turned off, what's to keep my neighbor from connecting to these speakers and playing "their" music?
l michael  Jun 28, 2023
1 answer
A
Greetings Mike, and a great question. This system can only have one device paired at any time. Once your device is disconnected from these, another can pair up. The only two things to avoid your neighbor from pairing would be keeping your device close, and paired, or turning the power to off.
thomas  Jun 28, 2023 (Staff)
Q
I'd let to have 4 of these speakers linked together is that possible?
emanuel  Jan 24, 2023
1 answer
A
That is a great question. Unfortunately these speakers don't have any inputs or outputs to link them to other components.
arielle  Jan 25, 2023 (Staff)
Q
can you power with 12v dc?
howle  Aug 22, 2022
1 answer
A
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)
Q
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
A
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  Aug 07, 2022 (Staff)
Q
do you need to power off after each use ?
thomas  Jul 12, 2022
1 answer
A
These do not need to be powered off.
