These are the rear surround speakers from a Revel Ultima Studio and Voice based home theater - you can find the other components listed separately here.
There's not too much to say about these other than the condition is great and the packing materials complete with the exception of a single cardboard flap on the box (which we will obviously deal with if they need shipping).
The speakers are available for view in Mountain View from 11am-7pm, Monday-Saturday. Add 3% if paying through PayPal. Please note that California residents will be have to pay sales tax.
