I have one Epik empire and am looking to add another subwoofer to my theater. I want to stay around $1000. I would not mind adding another empire but was wondering if there might be another option that would hit harder. Placement may be a problem. My room is 18ft across front, 15ft deep and 8 ft high. As I look at screen there is a 10 foot opening on left with rest of room enclosed. My sectional only allows placement in rear left corner or beside sectional on the right. Front corners of the room are filled with cabinet and fireplace. My empire is now in the left corner. The new sub would have to be along right side wall or swapped with empire. The hsu 15 inch ported and sealed subs have stellar reviews. I do not know if the would blend well with my empire. I am looking for the kind of bass that you feel in your chest. Thanks for any help.
