What the REL AirShip II Actually Does
The REL AirShip II is a wireless transmitter and receiver system, not a subwoofer. On its own it makes no sound. Its job is a specific and important one: it carries the signal from your system to a compatible REL subwoofer without a physical cable run across the room. If placing your sub where it sounds best means a long, awkward, or simply impractical wire, the AirShip II removes that obstacle while preserving the clean, low noise signal path REL insists upon.
Think of it as the freedom to position your subwoofer for the best acoustic result rather than the most convenient cable route. The transmitter sits at your source location, the receiver rides with the subwoofer, and the two communicate wirelessly so your low frequency information arrives intact.
Where the AirShip II Sits in REL's Wireless Range
REL offers a small family of wireless solutions, and the AirShip II is the highest performance option in the lineup. It sits above both the REL Arrow and the REL HT-Air MKII.
Each of these systems shares the same core goal of eliminating the wired run, but they are designed for different subwoofer families and performance tiers. The HT-Air MKII and Arrow are matched to their own compatible subwoofers, while the AirShip II represents REL's most refined wireless implementation for the models it is designed to serve. Because each transmitter system is engineered to work with specific subwoofers, the most important step is not choosing the most capable option on paper but choosing the one that matches your sub.
Why a Purpose Built Wireless System Matters
Bass is unforgiving of a compromised signal. REL builds its subwoofers to integrate seamlessly with your main speakers, and a wireless link has to honor that same standard of clarity and timing. The AirShip II is designed as REL's premium answer, giving you placement flexibility without introducing the noise, dropouts, or lag that a generic wireless kit might. This is why REL builds its own systems tuned to its own subwoofers rather than leaving the connection to chance.
The practical payoff is real. You can tuck a subwoofer into the ideal corner, place it behind seating, or move it across the room for stereo pairs and line arrays without running cable under carpet or around door frames.
Confirming Compatibility: The Most Important Step
Because the AirShip II serves a specific set of compatible REL subwoofers, matching it correctly is everything. A wireless system paired to the wrong sub simply will not do its job. Before you commit, confirm that your subwoofer is one the AirShip II is designed to serve.
Within REL's music focused and home theater ranges, popular candidates for going wireless include the REL T/5x, the REL T/7x, the REL T/9x, and the REL T/9x SE from the T/x series, along with the retro voiced REL Classic 98 and REL Classic 99. On the home theater side, subs such as the REL HT/1003 and the REL HT/1205 are built for LFE slam and may call for a wireless link when placement gets tricky.
Not every one of these subs uses the same wireless module, so the golden rule stands: verify that the AirShip II is the correct system for your exact model before purchasing. If it is not, one of REL's other wireless options, the Arrow or the HT-Air MKII, may be the intended match instead.
Ideal System and Use Case
The AirShip II is for the listener who wants REL's best wireless performance and owns, or is buying, a compatible subwoofer where a wired run is impractical or undesirable. It is equally at home in a two channel music setup where you want the sub tucked out of sight and in a home theater where routing cable to the ideal bass position is a headache. If you are considering a stereo pair or a stacked line array of RELs for greater output and a larger soundstage, wireless placement freedom becomes even more valuable.
Pairing Thoughts
Keep the pairing sensible and matched in intent. A premium wireless system pairs naturally with a sub whose performance and placement flexibility justify it. Rather than reach for the most expensive combination, choose the subwoofer that fits your room and system, then confirm the AirShip II is the wireless system REL designed for it. That single check protects your investment and guarantees the seamless result REL is known for.
