Its space-saving cabinet, wide sweet spot, and flexible acoustic tuning make it a strong fit for home studios, edit suites, and small professional control rooms where clarity, stereo imaging, and controlled bass response matter.\u003c\/p\u003e \u003ch2\u003ePreSonus Eris Studio 4 Competitive Differences\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eCustom EBM waveguide delivers a wide 120-degree horizontal sweet spot with focused vertical dispersion for improved stereo imaging and reduced desk reflections\u003c\/li\u003e \u003cli\u003eCompact 4.5-inch design with 50W Class AB biamplification, front-firing port, and tuning controls for accurate monitoring in smaller rooms\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003ePreSonus Eris Studio 4 Description\u003c\/h2\u003e \u003cp\u003eThe \u003cstrong\u003ePreSonus Eris Studio 4\u003c\/strong\u003e is designed to bring accurate monitoring and impressive low-end performance to compact production spaces. Its 4.5-inch woven-composite low-frequency driver produces tight, controlled bass with more punch than you might expect from a monitor this size, while the ported enclosure helps extend response down to 55 Hz. For producers and engineers working in smaller rooms, this makes it easier to hear the balance of a mix without moving to a much larger speaker.\u003c\/p\u003e \u003cp\u003eHigh-frequency detail is handled by a 1-inch ultra-low-mass silk-dome tweeter paired with PreSonus’ custom Elliptical Boundary Modeled waveguide. This design provides a broad listening area with natural stereo imaging, making the speaker especially useful in desktop setups where movement around the mix position is common. Narrow vertical dispersion also helps reduce reflections from work surfaces, improving clarity and preserving mix detail.\u003c\/p\u003e \u003cp\u003eThe monitor’s flexible rear-panel tuning controls allow users to tailor performance for their room and placement. Adjustable high-frequency and midrange controls, acoustic space settings, and selectable highpass filtering make it easier to optimize response whether the monitor is placed near a wall, on a desk, or used alongside a subwoofer. Balanced XLR and 1\/4-inch TRS inputs, along with unbalanced RCA connections, make the \u003cstrong\u003ePreSonus Eris Studio 4\u003c\/strong\u003e easy to integrate into a wide range of studio and multimedia systems.\u003c\/p\u003e \u003cp\u003eBuilt-in protection circuits add reliability for daily production use. RF interference protection, output-current limiting, over-temperature protection, transient protection, subsonic filtering, and a soft-start amplifier design all help the speaker operate cleanly and consistently. The result is a compact monitor that is well suited for mixing, playback, editing, and general studio reference duties.\u003c\/p\u003e \u003ch3\u003eEris Studio 4 Features\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eCompact powered studio monitor for small mixing rooms and desktop production setups\u003c\/li\u003e \u003cli\u003e4.5-inch woven-composite low-frequency transducer\u003c\/li\u003e \u003cli\u003e1-inch ultra-low-mass silk-dome high-frequency transducer\u003c\/li\u003e \u003cli\u003eCustom EBM waveguide with 120-degree horizontal and 60-degree vertical dispersion\u003c\/li\u003e \u003cli\u003eWide sweet spot with focused vertical control for reduced desk reflections\u003c\/li\u003e \u003cli\u003e50W Class AB biamplification\u003c\/li\u003e \u003cli\u003eFront-firing acoustic port for enhanced bass response\u003c\/li\u003e \u003cli\u003eAcoustic tuning controls for HF, midrange, acoustic space, and low cut\u003c\/li\u003e \u003cli\u003eBalanced XLR and 1\/4-inch TRS inputs plus unbalanced RCA input\u003c\/li\u003e \u003cli\u003eInternal power supply with IEC connector\u003c\/li\u003e \u003cli\u003ePower switch with on\/off LED\u003c\/li\u003e \u003cli\u003eBuilt-in protection for RF interference, output-current limiting, over-temperature, transient, and subsonic conditions\u003c\/li\u003e \u003cli\u003eSoft-start amplifier design helps eliminate popping on power-up\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eEris Studio 4 Specifications\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eProduct Type: Powered Studio Monitor\u003c\/li\u003e \u003cli\u003eLF Driver: 4.5 in woven-composite transducer\u003c\/li\u003e \u003cli\u003eHF Driver: 1 in (25 mm) ultra-low-mass silk-dome tweeter\u003c\/li\u003e \u003cli\u003eAmplifier Power: 50W Class AB biamplification\u003c\/li\u003e \u003cli\u003eMonitor Amplifier Power: 25W per Speaker\u003c\/li\u003e \u003cli\u003eFrequency Response: 55 Hz to 20 kHz\u003c\/li\u003e \u003cli\u003ePeak SPL: 99 dB at 1 meter\u003c\/li\u003e \u003cli\u003eCrossover Frequency: 2.7 kHz\u003c\/li\u003e \u003cli\u003eWaveguide Dispersion: 120 degrees horizontal x 60 degrees vertical\u003c\/li\u003e \u003cli\u003eAcoustic Space Settings: Flat, -2 dB, -4 dB\u003c\/li\u003e \u003cli\u003eLow Cut: Flat, 80 Hz, 100 Hz at -12 dB per octave\u003c\/li\u003e \u003cli\u003eHigh Frequency Control: ±6 dB, continuously variable, center 10 kHz\u003c\/li\u003e \u003cli\u003eMid Frequency Control: ±6 dB, continuously variable, center 1 kHz\u003c\/li\u003e \u003cli\u003eInputs: 1 x Balanced XLR, 1 x Balanced 1\/4 in TRS, 1 x Unbalanced RCA\u003c\/li\u003e \u003cli\u003eInput Impedance: 10 kOhm\u003c\/li\u003e \u003cli\u003eCabinet Material: Vinyl-laminated medium-density fiberboard\u003c\/li\u003e \u003cli\u003eConnection Type: IEC\u003c\/li\u003e \u003cli\u003eVoltage: 100 to 120V\u003c\/li\u003e \u003cli\u003eProtections: RF interference, output-current limiting, over-temperature, turn-on\/off transient, subsonic filter\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eWhat's In The Box\u003c\/h3\u003e \u003cul\u003e \u003cli\u003ePreSonus Eris Studio 4 powered studio monitor\u003c\/li\u003e \u003cli\u003eIEC power cable\u003c\/li\u003e \u003c\/ul\u003e","brand":"PreSonus","offers":[{"title":"Default Title","offer_id":51887972417818,"sku":"117005","price":129.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0894\/2714\/9082\/files\/presonus-eris-studio-4--4-5in-powered-studio-monitor--wide-sweet-spot-with-50w-class-ab-power_954559d1-d772-4dc6-a44c-617b7873319f.webp?v=1775065217","url":"https:\/\/squarecable.com\/products\/presonus-eris-studio-4-4-5in-powered-studio-monitor-wide-sweet-spot-with-50w-class-ab-power","provider":"SquareCable","version":"1.0","type":"link"}
