Premium Bookshelf Design

The Microlab B77BT is designed in a classic bookshelf style that seamlessly complements any room décor. Its compact rectangular shape and wooden cabinet construction make it ideal for placement on desks, shelves, or entertainment centers. The wooden MDF enclosure is not just for aesthetics—it plays a vital role in enhancing the acoustic performance by reducing vibrations and absorbing noise for cleaner audio output. This elegant and natural design fits well in modern or traditional setups, making it both a functional and decorative audio solution.

Powerful and Balanced Audio Output

Equipped with a powerful 2.0 channel stereo configuration, the B77BT delivers a total RMS output of 48 watts, ensuring high-volume performance without distortion. Each channel provides 16 watts of RMS power, supported by a 4-inch woofer and a 0.75-inch tweeter per speaker. The result is a dynamic and rich sound profile with deep, punchy bass and crisp, detailed treble. The built-in amplifier optimizes audio delivery, ensuring that music, movies, and dialogue are heard with clarity and depth, suitable for casual listening or immersive entertainment experiences.

Advanced Connectivity Options

The B77BT supports both Bluetooth 4.0 wireless streaming and traditional wired connectivity through a 3.5mm-to-2RCA input. This dual-mode capability allows users to effortlessly switch between wireless and wired sources, offering flexibility for a wide range of devices. Whether connecting a smartphone, tablet, laptop, or TV, the speaker delivers consistent performance across all media. The Bluetooth connectivity supports a range of up to 10 meters, ensuring stable playback without interruption or signal drops during use.

Customizable Sound Controls

For personalized listening preferences, the B77BT includes manual bass and treble control knobs located at the rear of the speakers. These allow users to fine-tune the audio to suit different music genres or personal preferences. A front-facing volume knob provides easy and quick adjustments during playback. This hands-on approach gives users complete control over their audio experience, making it ideal for those who appreciate adjusting sound output to match their environment or mood.

High-Quality Driver Configuration

The speaker set features a dedicated 0.75-inch tweeter and a robust 4-inch woofer on each unit. This driver setup ensures accurate reproduction of both high and low-frequency sounds. The tweeters deliver sharp, clear highs, making vocals and high-pitched instruments sound lifelike and distinct, while the woofers produce strong, full-bodied bass that adds depth to music and movie soundtracks. The separation and clarity between frequency ranges allow the B77BT to produce a full and immersive audio experience suitable for various multimedia applications.

Enhanced Bass Reflex Architecture

Each speaker cabinet incorporates a built-in bass reflex tunnel, which is designed to improve low-frequency response by efficiently managing airflow within the enclosure. This design enhances the bass performance, allowing the speakers to produce deeper, more resonant lows without requiring a subwoofer. The bass reflex system also reduces distortion at higher volumes, ensuring that sound remains clean and accurate, even during intense audio playback.

Versatile Multimedia Compatibility

The B77BT is highly compatible with a wide range of devices, including smartphones, tablets, PCs, TVs, MP3/MP4 players, and CD/DVD players. Its 3.5mm-to-2RCA input and 4-pin terminal output offer seamless connectivity options for both casual and professional setups. While it lacks USB ports, memory card slots, or a remote control, the focus remains on delivering premium audio performance through solid physical and wireless connections. Its simplicity, combined with high-quality sound and durable design, makes it an ideal choice for users looking for reliability, versatility, and superior sound quality.
