Key Takeaways

TLDR Summary: In the realm of compact speakers, the Audioengine A2+ Wireless boasts convenient Bluetooth connectivity, alluring for the modern listener who prioritizes seamless streaming. Its sound signature is crisp with an admirable clarity in the highs and mids, though bass enthusiasts may yearn for more depth. Meanwhile, the Micca RB42 Reference speakers, sans wireless functionality, demand a traditional wired setup but reward with a richer, fuller soundstage. The RB42's deliver a warm, encompassing bass that belies their modest footprint. Ultimately, the choice between these two boils down to the listener's weight on wireless convenience versus acoustic fullness.

Speaker Comparison

When it comes to compact bookshelf speakers that deliver substantial audio quality, the Audioengine A2+ Wireless Bluetooth Speakers and the Micca RB42 Reference Bookshelf Speakers stand out as popular contenders for a spot in your living space or office. Both speakers aim to blend a relatively small footprint with a soundstage that defies their size. The A2+ with its built-in DAC and wireless capabilities, and the RB42 with its rich bass performance and classic passive design, each offer a distinct flavor in the realm of personal audio.

Starting with the Audioengine A2+, these speakers offer a sleek, minimalist design that's perfect for the modern desk or shelf. Their aesthetic is one that blends seamlessly into any contemporary setting. The inclusion of Bluetooth aptX technology is a nod to convenience, allowing you to stream high-quality audio from your mobile devices without the hassle of cables. This wireless feature makes them an excellent choice for those who prioritize ease of use and clean setups without compromising on sound quality.

On the flip side, the Micca RB42s are a throwback in the best sense. These speakers require a separate amplifier or receiver but reward the extra effort with a warm and enveloping sound. The RB42’s larger drivers and rear port design contribute to a more room-filling bass which is often missing in speakers of this size. They are perfect for the traditionalist who enjoys the hands-on aspect of setting up and fine-tuning their audio system.

Sound Signature and Performance

When it comes to sound signature, the Audioengine A2+ presents a clean, balanced output with a focus on clarity and detail in the mids and highs. Although they may lack the deep bass of larger speakers, they compensate with a surprisingly punchy lower end for their size. These speakers are ideal for a range of genres from classical to acoustic where nuance in the higher frequencies is appreciated.

Comparatively, the Micca RB42 speakers lean towards a warmer, fuller-bodied sound. They're capable of delivering a more pronounced bass response, thanks in part to their larger 4-inch woofers and ported design. This makes them particularly enjoyable for bass-heavy music, movies, and gaming, where the impact of the lower frequencies enhances the overall experience. The midrange is rich and vocals come through with a natural tone that adds to their inviting sound.

Connectivity and Power

The A2+ comes into its own with its integrated digital-to-analog converter (DAC), which means you can connect them directly to your computer's USB port for an instant audio upgrade. This feature, along with their Bluetooth capabilities, means multiple devices can be connected simultaneously without the need for switching cables or inputs. The convenience factor here is a considerable advantage for the A2+ in today's multi-device world.

Conversely, the passive nature of the Micca RB42s means that they need a separate amplifier to function. This can be seen as an added expense or a customizable feature, depending on your perspective. For the audio purist, the ability to pair the speakers with an amplifier of their choice is appealing. It allows for more control over the sound and the potential for future upgrades. However, for someone seeking a more straightforward, all-in-one solution, this might be seen as a drawback.

Considerations for Space and Usage

Ultimately, the choice between the Audioengine A2+ and the Micca RB42 might come down to the intended use and the space they will occupy. The A2+'s compact design and built-in features lend themselves to a clutter-free office or bedroom setup, where space is at a premium, and simplicity is key. The wireless functionality is particularly handy in these environments where cables can be cumbersome.

In contrast, the Micca RB42s, with their more traditional bookshelf speaker design, might be better suited to a dedicated listening room or home theater setup where they can shine in partnership with the right amplifier. They offer a more immersive sound that benefits from a little extra room to breathe. The RB42s are for those who don't mind a more complex setup in favor of a potentially more rewarding listening experience.
