Ive seen more speakers completely ruined over the last 10 years from people trying to paint them black
,what is the deal with black speakers that would fuel the desire to destroy any future value of the speaker,other than for parts on ebay
Really,i dont get it at all,what does a black speaker have to offer that a cherry speaker dont,unless a living room is done in all black laquer(pretty tacky lookin) why wont a cherry finish fit the decor.
A word of advice for painting speakers,it will INSTANTLY drop the value of the speaker to zero,home made paint jobs end up looking like pure he!! & unless an automotive painter uses a high epoxy based primer before painting the finish will never hold,it will peel & chip like crazy,keep in mind that these type primers are not in the normal range of use in the automotive painting industry.
Even for a professional,painting (properly) over veneer that has a finished surface is not easy,it requires use of a high performance epoxy primer because the existing veneer is always too thin to properly sand out the finish,without removing the old finish normal primers will not sink in,they just lay on top of the wood causing a very poor bond.
My advice would be to either live with the finish you have now or to sell your speakers & use the proceeds twords a pair with a finish that you want,there is no cheap/lasting process to change a finish of a speaker, unless your skilled in cabinet refinishing yourself,then you can go over the old veneer with your chosen veneer.
