There will be no charts or graphs in this post. The setup was done with an RS SPL Meter and the Sound & Vision disk. My ears were the only tools used for this evaluation.
I have had six different subwoofers in the last 18 months searching for the right product at the right price. I have had this incredible subwoofer for over a week now and it continues to get better. My family room doubles as the HT room and presents a challenge for any single subwoofer, as it is approx 7000 cubic ft and has several large openings to other areas. Prior to the EP-600, the best sub for providing bass that can be both felt and heard had been my Velodyne DD-18. That sub was great for HT and music but was not a good fit (size wise) due to the way the room and furniture are laid out (WAF issues). The (very) vertical EP-600 and its relatively small footprint is a perfect fit in the room, but could it match the DD-18 in quality output? The answer for me (and the W) is an unequivocal yes. This subwoofer puts out the strongest cleanest bass I have heard in my space. I did extensive listening of both music and movies this past weekend the EP-600 just got better with each new challenge. From the Pearl Harbor attack to UB-571 to Batman Begins and Kingdom of Heaven this sub just nails all of the low frequency material. The 600 has none of the “overhang” or boominess that I have heard with other subs. I guess fast is the best way to describe the sound of the EP-600. Explosions, bass guitar notes or just the general movie low frequency rumble that is so prevalent these days, takes on a new character with this sub. I can honestly say that I have found my subwoofer for my HT. It meets all of my criteria in terms of quality output and affordability.
