Hello! Can you show me the on-axis frequency response graph of the eris sub8 (front firing) subwoofer? I have the intention to build up a presonus 2.2 monitoring system with two presonus eris e5 monitors at the sides and two eris 8 subs in the center position... I want to set up all the four speaker (subwoofers too) in line with my face (at my face height) with a distance between me and each monitor of 1,5 or 2 meters in the way for a full surround. To make this type of placement i need to know the exact on-axis frequency response of the eris sub8 (front firing) so i can chose the appropriate cut! Thank you for attention, have a nice day
