Description
With the SKAA Stage One XB Sub, the Stage One gets a significant dose of extra low-end. This compact active subwoofer is designed for anyone who wants more impact, depth, and body from their mobile PA system without relying on a large traditional subwoofer with long signal cables.
The XB Sub utilizes two 8-inch woofers in a compact bass-reflex enclosure. This combination provides surprisingly deep low-end response from a relatively portable system. According to the manufacturer, the frequency response ranges from 25 Hz to 180 Hz ±3 dB, ensuring the XB Sub not only provides a solid punch but can also reach deep into the sub-bass.
144 watts RMS amplification
To drive the system, the Stage One XB Sub features two Infineon Class-D amplifiers of 72 W RMS each. Together, this delivers 144 W RMS of amplification power.
The maximum acoustic output is 122 dB SPL. As such, the XB Sub is designed to deliver a clearly audible and tangible low-end extension without the subwoofer becoming unnecessarily large or heavy.
Two 8-inch woofers
The enclosure houses two 8-inch woofers with rubber surrounds. Each woofer has a continuous power handling of 80 W and a peak power of 120 W.
The dual-driver configuration provides extra cone surface area, making it possible to produce a powerful amount of low-end from a relatively compact cabinet.
The two woofers work in tandem with dual tuned bass-reflex ports, further optimizing air displacement and low-end response.
Extremely deep low-end
One of the most striking features of the Stage One XB Sub is the specified frequency range of 25 Hz to 180 Hz ±3 dB.
This is particularly interesting for music where low-end response is a vital part of the experience. Think of DJs, dance, house, electronic music, live music, and events.
The Stage One itself handles the mids and highs, while the XB Sub focuses on the lows. Together, they create a more complete and full-range PA system.
Fully wireless with SKAA
Just like the Stage One, the XB Sub utilizes SKAA and SKAA Pro. This allows the subwoofer to receive the audio signal wirelessly without a Wi-Fi network.
The reliable wireless range is up to 50 meters according to the datasheet, with actual range depending on the transmitter and antenna used.
This means you can easily place the XB Sub in a different position than the Stage One without having to run a long audio cable.
For mobile PA systems, this is a huge advantage.
SKAA Pro for professional applications
The XB Sub supports both SKAA and SKAA Pro. With a standard SKAA source, up to four receivers can be used simultaneously. With a SKAA Pro source, up to two receivers are available.
This allows the XB Sub to become part of a flexible wireless audio system where multiple compatible speakers and receivers work together.
Low latency
SKAA is developed for wireless audio transmission with low latency. For the Stage One XB Sub, the specified transport latency is approximately 36.71 ms in SKAA mode and 19.39 ms in SKAA Pro mode.
For a mobile PA setup, this is particularly interesting when the subwoofer is wirelessly combined with other speakers.
Long battery life
The Stage One XB Sub does not depend on mains power. The built-in Li-Ion 6S 2P battery has a capacity of 99.65 Wh.
At normal listening levels, the XB Sub can function for up to 40 hours according to the manufacturer. Even at full volume, the specified playtime is still up to 11 hours.
A full charge takes approximately 2.5 hours.
This makes the XB Sub particularly interesting for mobile applications where a power outlet is not always available.
Compact and mobile
With dimensions of approximately 27.4 × 61.7 × 49.5 cm including feet and a weight of only 15.5 kg, the XB Sub remains relatively easy to transport.
The enclosure is constructed from 12 mm birch plywood and finished with a black speckle coating. This combines professional construction with a size that fits well with mobile PA systems.
Perfect complement to the Stage One
The greatest strength of the XB Sub is revealed in combination with the SKAA Stage One.
The Stage One handles the mids and highs, delivering a wide and detailed sound with its 3-way design. The XB Sub takes care of the deep low-end.
The result is a system that sounds significantly fuller than a single Stage One and can provide a much greater impact, especially with bass-heavy music.
And because the connection is wireless via SKAA, you don’t need to run a traditional signal cable between the Stage One and the subwoofer.
