PreSonus Eris E4.5 2-Way 4.5″ Near Field Studio Monitor (PAIR)

The Eris E4.5 speakers’ 4.5-inch woofers result in tight bass that you can feel, as well as a 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. They also have 25 watts per side of onboard power that deliver clear and accurate audio.
