Summary: Excellent sound. Thunderous for the home theater. Have 4 of them hooked up (1 in each corner for balance). Patiently wait for a good deal on here. Every now and again you'll see a sub $400 seller for an $800 sub.
Summary: worked good until it stopped working. Second velodyne sub I have bought that just stopped. Good thing the store offers money back guarantee. Will never buy another velodyne product again. EVER
Summary: Don't buy this.. ive bought it, stop working 1 month after warranty and velodyne wont reconize they have problem with the main board and wont repair or make a deal.. 250$ can for the part and 60 $ for the repair .. so at this price will buy a brand new one and better quality.
Summary: My sub is dead. No sound reproduction.....everything looks working, but not sound anymore. I am in Brasil and have only one dealer/repair....i will see how much it will cost to repair....depending of the repair cost....i will have a new sub, but not Velodyne ! Sorry.
