GoHawk Motorcycle Bluetooth Speakers RD88-S Supreme Soundbar

In this review of the GoHawk RD88-S Supreme soundbar, the bottom line is simple: riders who want a compact, weatherproof motorcycle stereo with clear midrange and flexible hookup options will appreciate this unit. The RD88-S targets Harley touring riders, ATVs and scooters that need a tighter installation than separate fairing speakers, and its single biggest selling point is the six-driver array that delivers defined stereo separation and solid bass for a soundbar of this size.

Key Features

• Six high-output drivers: Four 1in silk tweeters, two 2.5in woofers and dual 1.6in passive radiators provide crisp mids and enhanced low-end for fuller sound on the road.
• 300W peak power: Peak output capability gives transient headroom so music stays clear at higher volumes during highway riding.
• Expandable via RCA: Dual RCA outputs let riders add two external speakers later to create a wider, more powerful outdoor stereo system.
• All-weather construction: IP56-rated aluminum housing and chrome finish resist rain, mud and vibration for reliable outdoor use.
• Multi-source playback: Bluetooth streaming, USB playback, 3.5mm AUX and FM radio provide versatile listening options from smartphones and USB drives.
• LED and remote: Machined bronze logo with blue/white LEDs and a backlit wired remote plus an LCD make mode and volume changes easy while riding.

Who It's For

The RD88-S is best for riders who want a single, compact stereo solution that mounts to 7/8 in to 1.25 in handlebars and offers more punch than a basic single-speaker setup. Touring riders with cruisers such as Harley-Davidson models will value the aluminum build, weather resistance and the built-in amplifier for a clean installation.

Those seeking extremely high SPL or studio-grade fidelity at loud volumes should look elsewhere or consider adding the optional external speakers via the RCA outputs. Also, if you need a custom-fit fairing installation rather than a handlebar soundbar, this form factor may not match that requirement.

Pros & Cons

Pros

Cons

• Some users report the maximum loudness can be limited for very noisy conditions or large open-vehicle setups.
• The chrome finish and LED styling may not match every bike aesthetic preference.
