Audio Pro C5 MkII W Review: Compact Wi-Fi Speaker With Serious System Ambition

The Audio Pro C5 MkII W is positioned as the smallest monoblock model in Audio Pro’s C-series, but its specification sheet suggests a speaker designed to do more than casual background playback. This second-generation W version adds a modernized app platform, broad wireless support, multi-room capability and a more flexible control system, all within a compact MDF enclosure. This review is an editorial assessment based on the documented design, features and specifications, not a hands-on listening test.

Design & Build Quality

The C5 MkII W follows the restrained Scandinavian design language Audio Pro is known for: a simple rectangular cabinet, clean lines and minimal visual clutter. It is compact enough for a desk, kitchen shelf, bedside table or small living-room surface, with dimensions of 130 x 250 x 150 mm and a weight of 2.4 kg. That makes it notably smaller than many traditional bookshelf speakers, while still housing amplification, wireless electronics and a three-driver front array in a single enclosure.

The cabinet is made from MDF, a sensible choice for a compact powered speaker because the material’s density helps control unwanted cabinet resonance. The speaker uses a bass-reflex arrangement, with an oval rear port intended to extend low-frequency output from the small enclosure. Because the port exits at the back, placement matters: leaving some breathing space between the speaker and a wall is advisable to reduce the risk of exaggerated bass or cabinet-boundary effects.

A removable magnetic grille is included. This is a practical detail because it allows the owner to choose between an exposed-driver look and a more discreet protected front. Magnetic attachment is also preferable to push-in plastic pegs from a longevity and usability standpoint. The speaker is offered in white, black and gray finishes, with the grille color matched to the cabinet while the drivers and tweeter grilles remain black.

Another thoughtful construction detail is the angled rubber foot arrangement. The front feet are taller than the rear feet, tilting the enclosure slightly upward. For a speaker likely to be placed below ear height, that geometry is acoustically purposeful: it helps aim the driver array toward the listener and may reduce immediate reflections from the supporting surface.

Driver Layout and Amplification

The Audio Pro C5 MkII W uses a three-driver configuration: one 4-inch long-throw mid-woofer for low and mid frequencies, supported by two 3/4-inch tweeters for the high-frequency range. The crossover is specified at 3800 Hz, while the claimed frequency range is 50 Hz to 20 kHz at -6 dB. For a compact all-in-one speaker, those figures indicate an engineering focus on extracting useful bass extension from a small cabinet without resorting to a physically large enclosure.

Amplification is handled internally by digital Class D amplification. The stated allocation is 25 watts for the mid-woofer and 2 x 8 watts for the tweeters, for roughly 40 watts of total system power. Because the amplifier, crossover and drivers are designed as one integrated system, Audio Pro has more control over gain structure and driver matching than would be possible with a passive speaker connected to an external amplifier.

The speaker supports streaming quality up to 24-bit/96 kHz and file formats including MP3, WMA, AAC, FLAC and Apple Lossless. Those capabilities do not guarantee a particular sonic character, but they show that the platform is not limited to compressed Bluetooth-style convenience playback. The underlying architecture is built to handle higher-resolution network audio within its supported ecosystem.

Features & Technology

The most important change in the W version is the integration of the Audio Pro W app platform, developed in collaboration with WiiM. That matters because much of the speaker’s appeal depends on network functionality rather than only its physical controls. Through the app, the C5 MkII W can access streaming services, internet radio, system settings, speaker grouping and audio adjustments.

Wireless support is broad. The speaker includes Wi-Fi on both 2.4 GHz and 5 GHz bands, plus AirPlay 2, Google Cast, Spotify Connect and support for TIDAL and Qobuz. Bluetooth 4.2 is also available for direct wireless pairing, but the more sophisticated use case is clearly network playback, where range, stability and service integration can be stronger than basic Bluetooth operation.

Multi-room support is central to the proposition. Multiple Audio Pro W-compatible speakers can be grouped, controlled centrally and adjusted independently. The compact C5 MkII W therefore makes sense not only as a standalone speaker, but also as a secondary zone speaker in a larger home audio arrangement. Six physical preset buttons further support that role, allowing quick access to saved services, playlists or radio stations without needing to open a phone every time.

Connectivity & Usability

Physical connectivity is more useful than expected for a compact wireless speaker. The rear panel includes RCA line input, a subwoofer output, a service USB port, a setup/reset button and the mains power connector. The RCA input allows connection to an external analog source such as a DAC or a turntable system with suitable phono amplification. The subwoofer output is especially welcome, because it gives the owner a clear upgrade path if deeper low-frequency output is desired in a larger room.

The speaker does not include an internal battery, so it is intended as a mains-powered home speaker rather than a portable outdoor unit. That design choice is consistent with the product’s multi-room and hi-fi-adjacent ambitions, but buyers looking for a grab-and-go Bluetooth speaker should note the distinction.

The top panel carries an unusually complete set of hardware controls: power, source selection, Bluetooth pairing, track navigation, play/pause, volume adjustment and six preset buttons. The source options include Wi-Fi, Bluetooth and line input. The volume control is specified with 100 steps, which should allow finer adjustment than basic low-resolution volume buttons. Even so, the most complete control experience is clearly through the Audio Pro W app.

App Control and System Setup

The Audio Pro W app is available for major mobile platforms and is required to unlock the speaker’s full network feature set. Initial setup involves joining the home Wi-Fi network, completing software updates where available and configuring the speaker inside the app. Once configured, the app provides access to presets, currently playing content, source selection, internet radio, grouped speakers and system settings.

The app’s deeper settings are extensive for a speaker of this type. Users can rename the speaker, check device information, configure a music alarm, manage presets, view internet connection quality and set an automatic standby timer. Audio settings include a 10-band equalizer spanning 31 Hz to 16 kHz, plus a range of prepared EQ presets. Input naming and input-specific volume behavior are also supported.

Additional streaming-related controls include Google Cast settings and access to Logitech Media Server for users with that kind of library infrastructure. This breadth reinforces the C5 MkII W’s identity as a compact network speaker rather than a simple Bluetooth box. Without the app, the product can still operate through Bluetooth or analog input, but its main advantages are tied to Wi-Fi streaming and software control.

Performance Potential and Value for Money

Because this is not a hands-on test, performance can only be assessed from the engineering choices and documented specification. On paper, the C5 MkII W has several ingredients that should help it perform credibly within its compact size class: a dedicated mid-woofer, dual tweeters, internal Class D amplification, a bass-reflex cabinet, 24-bit/96 kHz streaming support and adjustable DSP-style control through the app’s equalizer.

The rear-ported enclosure and claimed 50 Hz lower extension suggest Audio Pro has prioritized bass reach for a small cabinet, though placement will be important. The subwoofer output also reduces one of the usual limitations of compact all-in-one speakers by allowing the system to be expanded for more substantial low-frequency support.

Value depends heavily on the buyer’s intended use. The C5 MkII W is most compelling for someone who wants a compact, mains-powered home speaker with AirPlay 2, Google Cast, Spotify Connect, multi-room support and an analog input in one tidy unit. It is less ideal for users who only need casual Bluetooth playback or battery-powered portability. No USD price was supplied, so a numerical value judgment cannot be made here, but the feature set is broad for a speaker of this physical size.

Verdict

The Audio Pro C5 MkII W is a compact wireless home speaker with unusually broad streaming, control and expansion options for its size.

Conclusion

The Audio Pro C5 MkII W is best understood as a compact networked hi-fi speaker rather than a simple wireless convenience product. Its strongest assets are its well-considered MDF cabinet, three-driver amplified architecture, extensive Wi-Fi streaming support, app-based control and the inclusion of both RCA input and subwoofer output. AirPlay 2, Google Cast, Spotify Connect, TIDAL, Qobuz and multi-room grouping make it highly adaptable in modern homes, while six physical presets provide a useful shortcut for everyday listening habits. The limitations are equally clear: it is not battery powered, it does not include a remote control and its most valuable functions depend on the Audio Pro W app. Placement also deserves attention because of the rear bass-reflex port. For buyers who want a small, stylish, mains-powered speaker for a desk, shelf, kitchen or secondary room, the C5 MkII W looks like a strong and flexible option. Those seeking portability or a purely Bluetooth-first speaker should look elsewhere.
