Sound you can trust.
Eris studio monitors are used worldwide by audio engineers who need to hear every detail of their recordings. Ideal for gaming and home video production, the E4.5 BT uses the same technology as the larger Eris models to deliver studio-quality sound with a smooth frequency response in a compact size.

Convenient wireless Bluetooth connectivity.
With four different types of audio inputs, it’s easy to feed audio to your Eris E4.5 BT monitors from almost any source. Fast, reliable, stereo Bluetooth 5.0 connectivity lets you go wireless, streaming sound from a smartphone, tablet, laptop, or other Bluetooth source. Play games, listen to music, and even create content wirelessly. When you want a wired connection—say, from a computer, turntable, TV, or other line-level source—the Eris E4.5 BT has you covered with rear-panel, left and right ¼-inch TRS and RCA inputs and front-panel 1/8” stereo inputs. A loud, clear, front-panel headphone amplifier lets you work and play in stealth mode, without disturbing your housemates.
Clean overall sound, smooth high end, and a wide sweet spotEvery Eris-series studio monitor utilizes a woven composite low-frequency driver. The weave and nature of the Eris E4.5 BT’s 4.5-inch woofer result in tight bass that you can feel, as well as cleaner overall sound. The one-inch silk-dome tweeter produces a smooth and refined sound, accurately reproducing transients and high frequencies. The tweeter is designed to radiate sound with a fairly wide pattern, creating a large optimal listening area or “sweet spot” so you can move around and still hear an accurate stereo image. With 25 watts per side of onboard power, the Eris BT-series monitor speakers pack a serious punch, while still delivering clear, accurate audio. | Easy-to-use controls.A speaker’s response is affected by where you place it and the acoustics of your space.
