Ready for on- and off-road action
Own a Jeep Wrangler or side-by-side UTV? Then give your sound a big boost with this Alpine Turn1 Bluetooth speaker. It mounts easily to your vehicle's roll bar, and when you reach your destination, you can pop it off and take it along to keep the music playing. And the Turn1's built-in mic lets you take hands-free calls from your paired smartphone.
Big outdoor sound
The Turn1 features two tweeters and two midrange drivers plus a pair of side-firing passive bass radiators. Alpine tuned this speaker specifically for outdoor use. And they equipped it with 40 watts of built-in amplification, so you can be sure your tunes will sound great in the open air. Not enough? You can wirelessly pair two Turn1 speakers for true stereo sound.
Simple installation
The speaker's mounting bracket attaches securely to your vehicle's roll bar with four adjustable straps. The cast metal bracket has a foam underside cushion to prevent scratches to your roll bar. Another set of quick-release straps makes it easy to remove the speaker from the bracket and take it with you.
Other cool features
The built-in rechargeable battery delivers up to 12 hours of operation. A 3.5mm stereo minijack input means you can plug in a compatible portable music player. And the 3-foot carry strap is a nice touch when you're enjoying your tunes in the great outdoors.

Features
Outdoor Stereo Sound: With two midrange drivers, two tweeters, and two external passive radiators, the Alpine Turn1 (AD-SPK1) portable Bluetooth speaker provides a stereo sound performance that can produce up to 36-watts (RMS) / 40-watts (Peak) of powerful sound. The Bluetooth speaker is tuned specifically to be played outside, so even in open-air with wind or other noise, music still comes through clear.
Waterproof & Dustproof (IP67): The Alpine Turn1 (ADSPK1) portable Bluetooth speaker is waterproof and dustproof with an IP67 rating. It is 100% protected against solid objects like dust and sand; plus has been tested to work for at least 30 minutes while under 6" (15cm) to 39" (1M) of water.
Note: The unit is only IP67 certified in Bluetooth mode; it is not waterproof or dustproof when charging the battery or the Aux input is being used.
Bluetooth 5.0: The Alpine Turn1 (AD-SPK1) features built-in Bluetooth 5.0 with support for wireless audio streaming (A2DP/AVRCP), Hands-Free Communication (HFP), Simple Secure Pairing (SSP), and Near Field Communication (NFC). You can pair multiple Bluetooth devices with the Alpine Turn1 (AD-SPK1), but only one device can be used for playback and phone calls at a time. The speaker will automatically connect with the last paired device when its within wireless range (up to 33').
- Wireless Audio Streaming: You can wirelessly stream stored music libraries, online music apps, and other audio content from your Bluetooth-enabled device to the Alpine Turn1 (AD-SPK1) speaker. You can also control basic playback functions such as Play/Pause and Previous/Next Track from the Bluetooth speaker. Advanced music navigation and song/artist/album information will still need to be done from your Bluetooth source device.
- Hands-Free Communication: You can even answer calls on your Bluetooth connected phone from the Alpine Turn1 (AD-SPK1) speaker. A ring-tone will be heard through the speaker and you can use the speaker's top-panel controls to answer/end the call. The caller's voice will be heard through the speaker, while you speak into the unit's built-in microphone. You cannot make calls from the Alpine speaker. However, you can make a call from your Bluetooth connected phone and it will automatically transfer the call over to the Bluetooth speaker.
Note: Your Bluetooth music will be paused during a phone call and will automatically start back up when the call is ended.
True Wireless Stereo (TWS): Using Bluetooth, you can wirelessly pair two Alpine Turn1 (AD-SPK1) speakers together for True Wireless Stereo (TWS). You speaker will act as the left audio channel, while the other speaker acts as the right audio channel for a broader stereo soundstage.
Aux Input: In addition to Bluetooth wireless connectivity, the Alpine Turn1 (AD-SPK1) is outfitted with a 3.5mm Aux input for connecting an external audio source with an analog output or headphone jack. The Aux port is located behind a flip-out rubber cap.
Note: The Aux input takes priority over Bluetooth; when you have a Bluetooth source playing and you plug in a Aux source, the Bluetooth source will be muted and the Aux input will play.
Rechargeable Battery: A built-in rechargeable Lithium-ion battery (3600mAh) provides long-lasting playback time. The battery can be charged using the included microUSB-to-USB cable and an optional USB/AC power adapter (sold separately - see Accessories Tab). It has a charging voltage of 5V/1.7A. The auto power-off feature ensures efficient use of the battery when not in use for about 10 minutes.
- Playback Time: 7-8 hours (70% volume) or 12-14 hours (50% volume).
- Charging Time: 4-6 hours
Note: The Alpine Turn1 (AD-SPK1) does not comes with an USB/AC power adapter; one must be purchased separately in order to charge the built-in battery.
Roll Bar Mounting Bracket: The supplied mounting bracket system allows you to easily attach the Alpine Turn (AD-SPK1) portable Bluetooth speaker to your Jeep Wrangler roll bars or your Side x Side roll bars. The included cast metal bracket is designed with a foam backing to ensure protection from scratches on the your vehicle when installed.
Included Carry Strap: The Alpine Turn1 (AD-SPK1) comes with a 3' carry strap that is adjustable and padded. The carry strap comes pre-installed, but can be removed.

The Alpine Turn1 produces amazing sound from a fairly compact unit! It has better base than my JBL of similar size yet the highs are still crystal clear. I mounted it in my UTV and at the end of the day, it's still has enough charge to enjoy by the campfire. It won't disappoint!!
