There are many, though for my money the main competitors are Ohm (lousy website, great products: http://www.ohmspeakers.com/productline.cfm http://www.ohmspeakers.com/productline.cfm) and the DCM TFE series http://www.dcmspeakers.com/products/cabinet/tfe200.htm http://www.dcmspeakers.com/products/cabinet/tfe200.htm . Pair with heavy-duty 2-channel amplifier like the Onkyo M-282, or a decent Denon, Harman Kardon, NAD, etc. home theater receiver.
