The Eris Pro Sub 10 brings 250 watts of serious low-end power to your professional home studio or music production facility. The 10" glass-composite driver combines with a front-firing bass-reflex port to deliver clean, powerful low-frequency reproduction down to 20 Hz with excellent transient response. Add the Pro Sub 10 to your existing system and experience true full-range audio. The Pro Sub 10 is designed to integrate seamlessly with the PreSonus Pro series full-range monitors (sold separately) but can also be paired with any existing system. A continuously variable lowpass filter allows you to set the sub's effective operating frequency between 50-130Hz so you can choose the ideal crossover transition for a variety of full-range monitors. The rear panel features Stereo balanced XLR and TRS inputs, RCA unbalanced inputs, pass-thru outputs with a high-pass filter, and a subwoofer out for connecting a second Pro Sub 10 (sold separately). There's even a momentary footswitch (included) that removes the Sub Pro 10 from the chain so you can A/B your mix without it for easy reference.PreSonus ERIS-PRO-SUB-10 Features:10-inch, front-firing, glass-composite, low-frequency transducerFront-firing, bass-reflex acoustic portContinuously variable lowpass filter (50 Hz to 130 Hz) sets the upper frequency reproduced by the subwooferSwitchable highpass filter removes frequency content below 80 Hz from the full-range subwoofer outputs to the main monitorsMomentary footswitch (included) bypasses the subwoofer, highpass filter, and Sub OutInput gain control (-30 dB to +6 dB, continuously variable), polarity invert switch, and ground-lift switch170 watt (RMS), Class AB amplification for up to 113 dB SPL, with a frequency response of 20 to 200 HzLeft and right, balanced XLR and ¼-inch TRS and unbalanced RCA main inputsLeft and right balanced XLR and ¼-inch TRS outputs and XLR subwoofer output for connecting a second Eris® Pro Sub 10 PreSonus Eris Pro Sub 10 10 Active Studio Subwoofer.
