PRESONUS Eris E5 Active Studio Monitor (Each)

The PreSonus Eris E5 is an active studio monitor with a 5.25" Kevlar low frequency driver and a 1" low-mass silk-dome tweeter, which produce an accurate response with a tight bass and clear top end. Eris E5 monitor speakers are certainly no slouch in the volume department, featuring Class AB bi-amplification, with 45W LF and 35W HF power amp stages. They also come loaded with a range of professional acoustic-adjustment controls, boasting three EQ controls in its Acoustic Tuning section: High, Mid, and Low Cutoff. These controls enable you to adjust the monitors to the room you're in. The Low control is also useful when using the E5 with a subwoofer.
