Key Features
HONEST. Eris 3.5BT near field studio monitors deliver studio-quality, accurate sound perfect for music production, hi-fi audio listening, or multimedia reference.
EXPRESSIVE. Clear, accurate audio with a big low end — Eris 3.5BT's woven-composite woofers’ weave and nature result in tight bass that you can feel, as well as cleaner overall sound.
POWERFUL. Compact speakers that pack a punch — 50 Watts of Class AB dual amplification (25W per side) provide all the volume and loudness you want without sacrificing tonal balance or audio clarity.

ULTRA-WIDE LISTENING SWEET SPOT. The natural high-frequency response of the 1-inch low-mass, silk-dome transducers (tweeters) provide superior stereo imaging from nearly any listening angle.
ALL THE CONNECTIONS YOU NEED. ¼-inch TRS balanced inputs on the back panel for professional audio devices, unbalanced RCA inputs for consumer electronics, plus a convenient front-panel ⅛-inch TRS stereo aux input for your phone.
PRECISION-TUNE TO YOUR ROOM. High- and low-frequency tuning controls allow you to customize your audio output for your ears, room size, and speaker orientation. Whether on a desk, bookshelf, or next to a turntable or record player, Eris 3.5BT's produce clear, room-filling sound.
QUICK-SWITCH TO HEADPHONES. The easy-access front panel headphone output and built-in headphone amplifier allow for plug-and-play headphone media reference when needed.
ADD MORE LOW END. The 50W, 8-inch companion Eris Sub 8BT studio subwoofer delivers a massive low-frequency boost and Bluetooth connectivity to your Eris 3.5BT’s, creating a powerful 2.1 speaker system.

Pros & Cons
👍 Pros
- 50 watts of Class AB amplification (25W per side) delivers surprisingly full sound from a compact 3.5-inch form factor
- Bluetooth 5.0 plus three wired input types cover virtually any source device without adapters
- High- and low-frequency tuning controls let you compensate for room acoustics and desk placement
- Front-panel headphone output with built-in amp allows instant switching to private monitoring
👎 Cons
- 3.5-inch woofers have limited low-end extension, so bass-heavy production work may require adding the companion Eris Sub 8BT
- Compact driver size means they won't fill larger rooms with the same authority as 5-inch or larger monitors
- Bluetooth audio compression may not meet critical listening standards for final mix decisions
