For sale is a pair of ES1010i subwoofers in black. You can find the specs here emptek.com/es1010i.php These subs are gorgeous looking and more than adequate for music. I wouldn't recommend them for HT use in anything bigger than a medium sized room - unless you were using them along with bookshelf speakers as fronts. The reason I have a pair is I used them to set up a 2.2 system in a medium sized room. They have served me very well. I have now moved to a smaller room and the subs are overkill. I'm asking $375 shipped to CONUS for each subwoofer or $700 for the pair. I have all the original packaging. You can find a detailed review here: www.audioholics.com/subwoofer-reviews/emptek-es1010i These were purchased in Dec. 2013 and came with a 5-yr warranty on the cabinets and woofers. EMPTek (now RBHSound) has excellent customer service.
