Notes: Really great value monitors from PreSonus, packing a punch from 4.5-inch woofers despite their compact overall dimensions. Bluetooth connectivity for added versatility.

This monitor comes with free Studio One Prime and Studio Magic plug-ins.

Supplier's notes:
PreSonus Eris-series 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 Eris E4.5 BT employs the same technology as the larger Eris models to deliver studio-quality sound, with a smooth and accurate frequency response. Yet they're compact enough to fit almost anywhere.

Clean overall sound, smooth high end, and a wide sweet spot:

Every 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. That's why Eris E4.5 BT active media reference monitors offer controls to adjust the high- and low-frequency content, so your Bluetooth speakers always sound their best. A convenient front-panel volume knob sets both the speaker level and the integrated headphone amplifier's level.

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 1/4-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.

Accuracy defined:

Like all PreSonus speakers, the Eris E4.5 BT offers consistent, accurate listening, with the smooth and even frequency response that has made Eris studio and media reference monitors popular around the world. Their compact and powerful design makes them an ideal solution for any small space. Want extra-deep low end? Pair compact Eris E4.5 BTs with PreSonus' powerful Temblor T8 active subwoofer for a truly full-range sound system that fits almost anywhere.

Professional Performance and Design

M-Audio's BX4BT monitors produce 120 Watts of professional sound inside a futuristic design that delivers pro-grade sound. The two-way design features an Acoustically-inert MDF cabinet with bass reflex that pushes low frequencies through modern Black Kevlarr drivers. Plus, enhanced rear ports and computer-optimised natural silk dome tweeters deliver the full spectrum of frequencies needed for any type of media.

Front & Rear Panel I/O

The BX4BT monitors offer all the connections you need to playback audio from all your devices. The rear panel features 1/4", 1/8", and RCA inputs, while the front panel features 1/8" aux input and a headphone connection that turns the speakers off for private listening. This feature is great for those late nights in the home office or mixing sessions where you don't want to disturb anyone.

Speaker Placement Controls & EQ

The M-Audio BX4BT features a Left/Right Active Speaker Position Switch letting you choose which speaker is sounding from the Left or Right side. This is useful if you are left-handed and want the speaker with the front panel volume control on your left side, or vice versa. Also on the rear panel are High-EQ and Low-EQ controls to boost or cut the low end or add some shimmer to the highs.

Limitless Creativity with MPC Beats Software DAW - Effects and Instruments Included

The M-Audio BX4BT comes bundled with MPC Beats, the powerful music-making and recording desktop software DAW for Mac and PC based on iconic MPC hardware.

Supplier's notes:
Presonus' best selling studio monitors just got better! Eris 4.5 BT media reference monitors deliver studio-quality sound in an elegant, compact form factor that makes them ideally suited for bedroom studios, video production, and high-fidelity gaming setups.

With 25 watts per side of onboard power, the Eris 4.5 BT reference monitors pack a serious punch, while still delivering clear, accurate audio. The weave and nature of the Eris 4.5 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 refined high-frequencies and is designed to radiate sound with a wide pattern, creating a large optimal listening area. Improved speaker voicing over previous designs delivers richer lows and a smoother crossover transition for articulate, accurate transient reproduction through the frequency range and a less-fatiguing listening experience.

A convenient front-panel knob sets the level of both the power amp and the loud, clear headphone amplifier, with its front-panel jack. With four types of inputs, including fast, reliable, stereo Bluetoothr 5.0 connectivity, it's easy to connect just about any audio source to your Eris 4.5 BT reference monitors. High- and low-frequency controls let you easily adjust your Eris speaker's frequency response to compensate for the acoustics of your space and create the most accurate sonic reproduction possible.

Need a little more low end? Add an Eris Sub8 BT to build a perfectly matched 2.1 sound system that fits almost anywhere.

Notes: Excellent studio-quality sound in a compact package from this clever PreSonus design. 4.5-inch coaxial drivers deliver point source reproduction, for precise imagine and off-axis response.

Supplier's Notes:
The Eris Pro 4 reference monitors employ a single point-source coaxial design for clear and accurate sound reproduction. This design provides superior phase alignment between components and delivers a wide sweet spot, precise stereo imaging, and symmetrical dispersion patterns - unique advantages for Dolby Atmos immersive rooms as well as stereo mix environments.

The Eris Pro 4 also delivers finely detailed transient response, and stunning dynamics that create a natural and less fatiguing listening experience. A 1-inch ultra-low mass, silk-dome tweeter ensures snappy, accurate transient reproduction, while a 4.5-inch woven-composite woofer offers tight, clear bass, with plenty of punch and no flab. A ported enclosure and 80 Watts of power allows the Eris Pro 4 to reach down to 55 Hz.

Acoustic tuning controls let you configure the Eris Pro 4 for your room and three-way Acoustic Space tuning can compensate for the effects of speaker placement against a wall or in a corner.

Flexible input options let you connect almost any line-level source, from mixers to audio interfaces and more. You'll have no problem hooking your Eris speakers up to virtually anything. Lastly, provisions for wall and ceiling mounts make it easy to integrate Eris Pro 4 monitors into any stereo or multi-channel system.
