How are the speakers finished? A black piano finish would be done differently than a wood finish, or marble.
Cabinet finish.....
I have a a pair of Teledyne AR-9 towers that are in perfect working order, and the cabinets are a solid 8-9 in rating but I want to gloss the finish up a bit, what can be used with good results to get a nice rich semi-gloss to glossy effect? thanks Chad
