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.

Q
Is it loud enough to hear over a Harley davidson motorcycle when running down the road?
[ Danny  Jul 22, 2022 ]
1 answer
A
This Alpine gets pretty loud, Danny. Now a punched out S&S motor with those shorty Screaming Eagle straight pipes this could have issues with, of course! However if you aren't running a fairing, don't want to install a head unit/amp/speakers setup these are pretty slick. You could essentially use the included roll bar universal mount to put this anywhere it fits on your Harley. Being waterproof too makes this a pretty good solution!

Q
Will it mount to a boat t-top?
[ Tyler  Jun 28, 2022 ]

This Alpine Turn1 Waterproof Bluetooth speaker will basically mount to anything, Tyler! It's super flexible. Your mount base has those two adjustable straps to mount to a wide variety of roll bars and pipe sizes, so most likely you will be able to mount it to the boat t-top! This Alpine BANGS for the size too, we love this unit.

If you find room,it's fairly big & heavy , but sounds great
[ SHELDON  Feb 27, 2022 ]
A
I can't answer this conclusively. I was going to mount it to my golf cart but did not try
[ DOUGLAS  Feb 27, 2022 ]
A
It would probably depend on the style of motorcycle and specifically the handle bar configuration. They work great in my Jeep and Can Am UTV. On the bigger full dress cruisers I think you could figure out a mounting location. The looks of the installation may not be pleasing to the eye. These speakers emit sound from both ends of the tube. I would build a cardboard model to scale and try out all possible locations on your bike. If you don't need stereo sound and a single mixed source will do, placement of a single speaker would work much easier. Engine and wind noise could also be a factor with or without a fairing. The speakers produce good sound levels in a large room, garage or outdoors, but may not be enough for use when riding. I use mine for music at the destination and seldom during driving activities. They are great on a golf cart as well. I do have a pair of these and the stereo separation is very good. The water and dust proof features are well done. Material quality is also excellent. Hope this helps.

Can this be used on a jetski?
[ Mel  Nov 26, 2021 ]

Mel, I do not have a jet ski. 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. From the specs it should work, but I am not sure the sound would be able to be heard clearly at speed and rough water conditions. Once you arrive at a rest stop or destination they will work fantastic. If you are looking for loud clear music while riding, I think more power will be necessary. Traffic and road noise can limit sound quality and clarity when used in an open jeep or side by side. Your vehicle speed and terrain will play a big part. Give them a try since there is a 60 day free trial. Paul

Q
Could this be used on a Motorcycle?

Its build quality would allow it to be used on a motorcycle as long as you have a place to mount it.
