ULTIMEA SUB10 10-Inch Powered Subwoofer with Wireless Adapter

ULTIMEA SUB10 is a powered 10-inch subwoofer with a wireless signal adapter and app-based bass controls. Its stated 550-watt peak output, adjustable crossover and multiple wired inputs suit compatible home audio systems, but the wireless link does not remove the need for AC power.

At a glance

The included adapter transmits the audio signal wirelessly and is claimed to pair with up to two SUB10 units. Each subwoofer still needs AC power.
The app is described as controlling volume, a 30-180Hz low-pass crossover, 6-band parametric EQ and phase from 0° to 180° in 1° steps.
Line/LFE, RCA, XLR and speaker-level connections provide options for compatible audio systems.
The listing states 550 watts peak output and low-frequency response down to 20Hz. These are manufacturer claims, not independently verified measurements.

Pros and cons

Pros

Wireless signal transmission can reduce the need to run a subwoofer audio cable across the room, while the unit remains mains-powered.
App-based equalization, crossover and phase adjustment offer several ways to tune integration with main speakers.
Multiple connection types accommodate a range of compatible receivers, amplifiers and powered speaker setups.
The listed package includes a protective grille and several audio and power cables.

Cons

Wireless operation still requires AC power at the subwoofer, so it is not a cable-free installation.
Compatibility is limited by the source output. The listing specifies a low-level signal below 2V for its soundbar and wireless-adapter guidance.

Who is it for?

A good fit for

Home-theater listeners adding dedicated bass to a compatible AV receiver or powered speaker system.
Buyers who want app-based crossover, EQ and phase adjustment for matching bass to their speakers.
Setups where avoiding a long subwoofer signal cable is useful and an AC outlet is available near the subwoofer.

Less suited to

Systems that only provide an incompatible passive-subwoofer connection or lack a suitable low-level signal input path.
Installations needing a subwoofer that does not require a nearby AC power connection.
Outdoor or wet locations, as the listing says it is not water resistant.

Frequently asked questions

Does the SUB10 work without a power cable?

No. The adapter sends the audio signal wirelessly, but the subwoofer itself still requires AC power.

Can the wireless adapter serve two subwoofers?

The listing says one adapter can pair with up to two SUB10 units. Each unit still needs its own AC power connection.

Will it connect to any soundbar?

Not necessarily. The listing requires a low-level signal below 2V from a suitable Sub Out and says it is incompatible with soundbars designed for passive subwoofers.

What can be adjusted in the app?

The listed app controls include volume, a 30-180Hz low-pass crossover, 6-band parametric EQ and phase adjustment from 0° to 180° in 1° steps.
