This is a DIY build of a RJB Design (Roman Bednarek) I really love this speaker but due to financial problems I am forced (by my wife) to sell off some of my collection. This speakers uses one of the most highly acclaimed tweeters available. The Hiquphon OW1 is a 3/4" soft dome tweeter that has excellent dispersion and blends in so seemlessly its sounds "invisible" Truly amazing sounding speakers. Excellent detail and imaging. The cabinets have cherry veneer on top, sides, back and bottom. The baffle is solid curly cherry. Crossovers use all Jenzen inductors and Mundorf capacitors.
