When you spend as much time around boats, beaches, campsites and backyards as we do on Cape Cod, a portable speaker has to do more than sound good. It needs to survive the environment. Salt spray, sand, rain, drops on the deck and the occasional dunk are all part of the game.
That is where the Turtlebox Cub really separates itself.
The Cub takes the rugged DNA of Turtlebox's larger speakers and puts it into a much more portable package. At just 8.6 inches tall, 7.2 inches wide and 5.75 inches deep, and weighing 5.3 pounds, it is compact enough to carry just about anywhere without sacrificing the big sound Turtlebox is known for.
Built for the Cape Cod Lifestyle
The first thing that stands out about the Cub is its construction. This isn't a speaker you have to baby.
It carries an IP67 waterproof rating, is buoyant, and can be submerged in up to three feet of water for 30 minutes. Turtlebox also describes it as drop-, crush- and dust-proof. For anyone who fishes, boats or spends summer days on the beach, that kind of protection is a major advantage.
And the floating feature is particularly reassuring on a boat. If the Cub goes over the side, you have a chance to retrieve it rather than watching a $330 speaker disappear into the Cape Cod Bay.
One important note: after exposure to saltwater, Turtlebox recommends rinsing the speaker with fresh water, and the charging port should remain closed around water. It should never be charged while wet or connected to power around water.
Don't Let the Size Fool You
The Cub may be small, but it isn't a small-sounding speaker.
Turtlebox rates it at up to 118 decibels, with a 4.5-inch woofer, 1.3-inch titanium tweeter and Class D digital amplifier. The result is a speaker that can easily provide the soundtrack for a beach day, backyard gathering, fishing trip or boat ride.
What impressed us most about the Cub is that its design prioritizes outdoor use. Turtlebox says it is ideal for groups of up to 20 people, although the larger Original is the better choice when you need greater bass and sound carry for a bigger gathering.
In other words, the Cub isn't trying to replace a giant party speaker. Its strength is delivering big, clean, powerful outdoor sound without making you carry a giant box around.
Excellent Battery Life
Battery life is another strong point.
The Cub is rated for 14+ hours of premium sound on a single charge, with USB-C charging and a 49.95 Wh lithium-ion battery.
That is plenty of runtime for a full day on the boat, a long afternoon at the beach or a weekend of camping. USB-C charging is also convenient because you aren't stuck carrying a proprietary charger everywhere you go.
Party Mode Is a Great Feature
One of the Cub's best features is its ability to connect with other Turtlebox speakers.
Using Party Mode, you can pair multiple compatible Turtlebox speakers together for a much larger sound field. The Cub can also use True Wireless Stereo to pair two Cubs in left/right stereo configuration.
That gives you the option of starting with one compact speaker and expanding your setup later.
For a large outdoor gathering, multiple Turtleboxes can make considerably more sense than trying to make one speaker do everything.
Perfect for Boats, Beaches and Backyards
For Cape Cod, the Cub makes a lot of sense.
It is small enough to throw into the truck before heading to the beach, compact enough to fit aboard a boat without taking up valuable space, and tough enough to handle the inevitable bumps and splashes that come with being around the water.
The stainless-steel tie-downs and rubber feet are also thoughtful touches for boaters. The speaker isn't designed simply to sit on a living-room shelf—it is built around the realities of outdoor use.
It is equally at home at a backyard cookout, campsite, tailgate or even sitting beside you while you're rigging tackle.
Cub vs. Turtlebox Original
The obvious question is whether you should buy the Cub or step up to the larger Original.
Turtlebox itself positions the Cub for smaller gatherings and more portable applications. The Original produces more bass and carries sound farther, while also offering a larger battery and additional inputs.
For most individual anglers, boaters and beachgoers, however, the Cub's smaller size is a major advantage.
You're much more likely to actually bring it with you.
The Bottom Line
At $330, the Turtlebox Cub isn't competing with inexpensive Bluetooth speakers. It is competing on a different set of priorities: durability, outdoor performance, portability and sound.
And that's what makes it such an appealing piece of gear.
The Cub is small enough to carry, loud enough for a group, tough enough for the outdoors and waterproof enough for life around the water. For Cape Cod anglers and boaters who want music without worrying about every splash, sandy hand or sudden rain shower, it is a particularly compelling choice.
The Turtlebox Cub is a great example of the philosophy that sometimes the best outdoor gear isn't the gear with the most features—it's the gear you don't have to worry about.
For summer on Cape Cod, that's a pretty valuable feature.
