This unit was damaged by shipper. I have had replacement hardwood top and bottom panels manufactured and have replaced the mid-range driver with OEM from Revel. The unit will occasionally drop in level after some use. I have had the speaker checked locally; all drivers appear to be intact and functioning properly. It appears that the crossover is the source of the intermittent; the crossover also shows signs of physical damage, again probably from the shipper damage. I have since replaced the unit with a new Revel Voice 2. This is a wonderful speaker when working properly.
Given the background I have outlined above, this sale is AS IS, WHERE IS, WITH ALL FAULTS.
