The Cub portable speaker is engineered to deliver high‑output audio performance in a compact, durable format suited for outdoor and mobile use. Measuring 8.6 inches in height, 7.2 inches in width, and 5.75 inches in depth with a weight of 5.3 pounds, it integrates a Class D digital amplifier driving a 4.5 inch woofer and 1.3 inch titanium tweeter to produce sound levels up to 118 decibels. A rechargeable 49.95 watt‑hour lithium‑ion battery provides more than 14 hours of runtime on a single charge, supported by Bluetooth 5.4 connectivity for stable wireless operation.

The housing is rated IP67 for water and dust resistance, allowing submersion up to 3 feet for 30 minutes while maintaining buoyancy. A rugged construction designed to resist drops, crushing force, and debris enhances durability in demanding environments. Party Mode enables multi‑speaker pairing for expanded sound coverage, while true wireless stereo allows left and right channel separation. Integrated touch controls manage playback, volume, and pairing functions, and USB‑C support allows efficient charging and device power output.
