The Eris 3.5BT media reference monitors deliver studio-quality sound in a sleek, compact format, making them ideal for home studios, video productions, and high-fidelity gaming setups. With a power output of 25 watts per side, the Eris 3.5BT reference monitors provide impressive performance while ensuring clear and precise audio playback. The 3.5-inch woofer of the Eris 3.5BT delivers rich, palpable bass and a clear sound image thanks to its design and construction. The 1-inch silk dome tweeter produces refined high frequencies and is designed to radiate sound in a wide pattern, creating a large optimal listening area. The improved intonation of the speaker compared to earlier models results in fuller bass and a smoother transition, leading to articulated, precise transient reproduction across the entire frequency range and a less fatiguing listening experience. A convenient knob on the front adjusts the level of the amplifier and the loud, clear headphone amplifier, which connects via a jack on the front. With four types of inputs, including the fast and reliable stereo Bluetooth 5.0 connection, it is easy to connect nearly any audio source to the Eris 3.5BT reference monitors. The high and low-frequency controls allow you to easily adjust the frequency response of your Eris speakers to compensate for room acoustics and achieve the best possible sound reproduction.
