Got my dual Empires yesterday. All I can say is WOW!!! These two subs filled my ~13,000 cubic feet with a TON more sound than my 17 yr old Velodyne F-1200 did.
I played some of my reference music CDs right off - stuff I know intimately, starting with The Great Organ At Methuen (one of the best pipe organs in the world) with master organist Michael Murray playing J.S. Bach's Fantasia and Fugue in G minor -- that will blow your mind if you're a basshead. Then I played Flim & the BBs' Tricycle
, which is one of the best quality recordings I know of, with tremendous "thump" and fidelity. Wow! Then I played the first 15 mins of The Bourne Ultimatum
at full reference level. HOLY CRAP!!!
I'm running a Denon AVR-3200 with B&W DM601s on the right and left and a matched B&W center (don't remember the model). B&W DM100s in the back.
Started w/ the subs side-by-side in front of the audio rack, separated by only a few inches, but aimed w/ the fronts at a 45º angle relative to the room. Later in the day, my 50' cheapie RCA connects arrived and I moved the subs - 1 to the front right corner - about a foot away from the side wall and 2 feet from the front wall, in front of the piano - firing right and left. The other Empire went at the back of the room, next to the fireplace (off center and about 6 feet from one side wall) and up against the back of the built-in cabinets. I did a very brief "subwoofer crawl" and decided this positioning would suffice for a few days 'til I can do more in depth analysis.
Can't say how the Emprires compare to anything but my old Velo F-1200 - but ONE Empire blows it away in depth and impact. They sound "warmer" and full and grounded to me than the Velo did, which seemed so tight and controlled as to be somewhat "sterile".
Oh - regarding hookups... It's been about 15 years since I fooled around with the settings/options in the Denon, so I'm not sure what's what. The cable currently comes out of the pre-out "subwoofer" out on the back of the Denon, into a "Y" splitter, and then from there into the "Crossover" input on each Epik. I tried using the "LFE" input on the Epiks, and it sounded horrid - flat, lifeless and muddled with a lack of depth.
Anybody happen to know off the top if there's a better connection option? Don't recall if my satellites are set to "small" or not in the setup. (The receiver's video output isn't hooked up to the TV at present - have to disconnect the DVD IIRC to connect the receiver's video for the setup screens to show on the TV.)
