GTA-400M, GTA-800M specifications

Boston Acoustics has long been a prominent name in the world of high-fidelity audio systems, and its GTA series of speakers exemplifies the brand's commitment to delivering exceptional audio experiences. Two standout models in this line are the GTA-800M and GTA-400M, both designed to meet the needs of discerning audiophiles and casual listeners alike.

The Boston Acoustics GTA-800M is a floor-standing speaker that delivers powerful, dynamic sound with its dual 8-inch woofers. These woofers work in tandem to produce deep bass response without compromising clarity in the mid and high frequencies. The speaker features a 1-inch aluminum dome tweeter that ensures smooth high-frequency reproduction, providing an expansive soundstage that fills any room. This model has been engineered to handle high power levels, making it an ideal choice for both music and home theater applications.

Meanwhile, the GTA-400M is a compact bookshelf speaker that stands out for its versatility and performance. Equipped with a 4-inch midrange driver and a 1-inch tweeter, the GTA-400M excels in producing detailed sound with excellent imaging. Its smaller size makes it perfect for limited spaces, yet it does not sacrifice audio fidelity. The GTA-400M is equipped with advanced bass port technology, allowing it to deliver a more extended low-frequency response, making it an excellent choice for music lovers who appreciate rich bass without the need for a subwoofer.

Both models come with Boston Acoustics' proprietary technology, including the advanced waveguide design, which improves dispersion and optimizes sound distribution across the listening area. This ensures that no matter where you sit in the room, you can enjoy a consistent audio experience. The cabinets of both models are constructed from high-quality MDF, providing durability and minimizing resonance, while the elegant finish adds a touch of sophistication to any room.

In terms of connectivity, the speakers are equipped with high-quality binding posts that accommodate a wide range of speaker cables, making setup a breeze. Whether you are building a state-of-the-art home theater system or simply looking to enhance your music listening experience, the Boston Acoustics GTA-800M and GTA-400M are exceptional choices. With their combination of advanced technologies, elegant design, and superior sound quality, these speakers are sure to satisfy any audio enthusiast.
