Compact Studio Monitors with Honest, Accurate Sound

The PreSonus Eris 4.5 BT 2nd Gen are 4.5-inch media reference monitors built for home studios, video production, and gaming setups where desk space is limited. With 25 watts per side and a 2-way active design, they deliver clear, even audio across the frequency range. This model is the right choice for creators who need studio-grade monitoring without the footprint of larger nearfields. Bluetooth 5.0 lets a phone or laptop stream straight to the cabinets, and improved voicing over the previous generation brings richer lows and smoother crossover transition.

What Sets These Monitors Apart

Inside each cabinet, a 4.5-inch woven glass-fiber composite woofer pairs with a 1-inch ultra-low-mass silk-dome tweeter through a 2.8 kHz crossover, creating a wide optimal listening area. The Class AB dual amplifier delivers 50 watts total with a peak SPL of 100 dB at 1 m. High and Low Acoustic Tuning controls (±6 dB, centered at 10 kHz and 100 Hz) compensate for placement against walls or corners.

Power and Amplification — Headroom for Real Sessions

Each driver runs on its own dedicated amplifier channel, improving transient response and lowering distortion compared to passive designs at this tier. The dual-mono configuration keeps left and right channels electrically separate for accurate stereo imaging.

• Total Power: 50 W — 25 W per side, enough headroom for tracking and mixing at nearfield distances
• Amplifier Type: Class AB dual mono — dedicated channels for each driver on both sides
• Peak SPL: 100 dB @ 1 m — plenty of volume for bedroom and small-room setups

Drivers and Frequency Response — What You Hear

Driver materials are chosen for a flat, honest response rather than a hyped consumer sound. The woven-composite woofer stays stiff for tight bass, while the silk dome tweeter avoids the harshness metal domes can introduce on long sessions.

• Woofer: 4.5-inch woven glass-fiber composite — stiff cone for tight, controlled low end
• Tweeter: 1-inch ultra-low-mass silk dome — smooth highs with wide dispersion
• Frequency Response: 70 Hz – 20 kHz — full-range coverage for music and video post
• Crossover Frequency: 2.8 kHz — smooth handoff between drivers for coherent imaging

Connectivity and Room Tuning — Plug In Anything

Four input types cover every common source, from an audio interface to a phone. The front-panel headphone jack with its own volume knob turns the monitors into a desktop listening station for late-night work.

• Inputs: Bluetooth 5.0, 2× balanced 6.3 mm TRS, 2× RCA, 1× 3.5 mm stereo — covers interfaces, mixers, computers, and phones
• EQ: 2-band Acoustic Tuning (HF ±6 dB @ 10 kHz, LF ±6 dB @ 100 Hz) — compensate for desk or wall placement
• Headphone output — front-panel jack with dedicated level control for silent monitoring

Who Should Buy the Eris 4.5 BT 2nd Gen

The Eris 4.5 BT is the right choice for bedroom producers, podcasters, and video editors who need accurate nearfield monitoring in a compact cabinet. Gamers benefit from Bluetooth 5.0, which streams from a phone or tablet without touching the wired connections. Content creators with an audio interface will appreciate the balanced 6.3 mm TRS inputs, while RCA and 3.5 mm jacks connect a TV or media player for casual listening. The included cables mean the pair is ready to use straight from the box, and the matching Eris Sub 8BT can be added later for a 2.1 setup.
