102 dB (E5) maximum continuous SPL When youre ready to get serious about recording, its time to step up to PreSonus Eris-series studio monitors. Cheap computer speakers and home-stereo speakers wont reveal the truth about your mix. They arent designed for that. In contrast, Eris speakers are real studio monitors, delivering a very accurate response with a tight bass and very clear upper end. Thats what you need in a home studio. Thanks to well-designed Kevlar low frequency transducers, low-mass silk-dome tweeters, responsive Class AB amplification, and professional acoustic-adjustment controls, Eris delivers the goods. Yet Eris-series speakers are ultra-affordable, making them a terrific value. And with two models, you can easily find the Eris monitor that best suits your studio needs. If space is at a premium, or if you want the ultimate in portability, consider the compact Eris E5, which takes up just 7 x 10.24 x 7.68 inches (178 x 260 x 195 mm) and weighs in at just 10.2 lbs (4.63 kg). You can shoehorn this little beauty into almost any studio space. The E5 sports a 5.25-inch, Kevlar low-frequency driver, mated with a 45W, Class AB amplifier; and a 1-inch (25 mm), silk-dome tweeter powered by a 35W, Class AB amplifier. It can crank out a clean 102 dB SPL, peak. Frequency response is rated at 53 Hz to 22 kHz. For a studio monitor in its size and price class, thats impressive. All Eris speakers have front-ported enclosures made of vinyl-laminated, medium-density fiberboard (MDF).
