It's a good thing I own a drill press or I would have had a difficult time fitting the bracket to my drum throne. It does not come with any holes pre-drilled and I also had to drill out the rivets holding the rubber feet on the bracket so I could mount it to my throne. Without a drill press it would be a daunting task to drill through the thick metal.

Great service and easy installation. These add so much to the home theater experience!

Works as advertised. The only issue is the need to tighten down the bolts holding the transducer to the mount. Only 1 wrench is included which doesn't allow you to fully tighten it which results in a little rattling. Once I fully tightened the bolts the rattle went away.
