{"product_id":"presonus-eris-studio4-4-5-active-studio-monitor","title":"PreSonus ERIS-STUDIO4 4.5\" Active Studio Monitor","description":"\u003cp\u003eThe PreSonus Eris Studio 4 is a single 4.5-inch, 2-way active nearfield studio monitor designed for music production, recording, editing, and critical everyday listening. Its built-in biamplified power section eliminates the need for an external speaker amplifier. It is well suited to compact home studios, desktop production setups, and small mix rooms.\u003c\/p\u003e\u003cp\u003eWith a 4.5-inch woven glass-fiber composite low-frequency driver and a 1-inch silk-dome tweeter, the Eris Studio 4 is voiced for detailed monitoring across a 55 Hz to 20 kHz frequency range. The 50-watt Class AB biamplified design supplies 25 watts to each driver section. Peak output is rated at 99 dB SPL at 1 meter.\u003c\/p\u003e\u003cp\u003ePreSonus uses an Elliptical Boundary Modeled, or EBM, waveguide to shape high-frequency dispersion. Its 120-degree horizontal by 60-degree vertical coverage is intended to create a broad listening area while helping reduce early reflections from a desk or console. The 2.7 kHz crossover integrates the woofer and tweeter sections.\u003c\/p\u003e\u003cp\u003eRoom-adjustment controls help tailor the monitor to practical placement conditions. Continuously variable high- and mid-frequency controls, selectable low-cut filtering, and Acoustic Space compensation provide useful adjustment when a monitor must sit near a wall or corner. A front-firing port supports low-frequency output while allowing more flexible desk placement than a rear-ported design.\u003c\/p\u003e\u003cp\u003eBalanced XLR and 1\/4-inch TRS inputs support connection to an audio interface, mixer, or monitor controller, while the RCA input accommodates unbalanced sources. For stereo monitoring, use two Eris Studio 4 monitors, one for each channel. The monitor can also be incorporated into a 2.1 setup by using its low-cut control with a suitable subwoofer system.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e4.5-Inch Composite Woofer:\u003c\/strong\u003e Delivers controlled low-frequency reproduction from a compact active monitor.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1-Inch Silk-Dome Tweeter:\u003c\/strong\u003e Provides detailed high-frequency response and transient reproduction.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEBM Waveguide:\u003c\/strong\u003e Creates 120-degree horizontal and 60-degree vertical sound coverage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e50-Watt Biamplification:\u003c\/strong\u003e Uses separate 25-watt Class AB amplifier channels for each driver.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAcoustic Tuning Controls:\u003c\/strong\u003e Helps adapt monitor response to room placement and system needs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThree Analog Inputs:\u003c\/strong\u003e Supports balanced XLR, balanced TRS, and unbalanced RCA connections.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe Eris Studio 4 uses a vinyl-laminated medium-density fiberboard cabinet with optimized internal bracing and a front-firing acoustic port. Its 2-way layout combines a woven glass-fiber composite woofer with an ultra-low-mass silk-dome tweeter. The cabinet measures 10 inches high, 7 inches wide, and 7.28 inches deep, with a weight of 8.82 pounds.\u003c\/p\u003e\u003cp\u003ePlace each monitor vertically, with the tweeter at seated ear height, and angle the pair inward toward the listening position. PreSonus recommends positioning monitors 8 to 12 inches from walls when possible; use the Acoustic Space switch when placement near a wall or corner is necessary. Connect only one line-level source to each monitor at a time, use balanced cabling where available, and connect the included IEC power cable to a grounded AC outlet.\u003c\/p\u003e","brand":"PreSonus","offers":[{"title":"Default Title","offer_id":45669173329990,"sku":"ERIS-STUDIO4","price":114.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/61RatFb1prL.jpg?v=1784479993","url":"https:\/\/audiowatt.store\/products\/presonus-eris-studio4-4-5-active-studio-monitor","provider":"Audio Watt Store","version":"1.0","type":"link"}
