Huge greetings to all fans and connoisseurs of beautiful JBL 4345! I recently sold my favorite 4350 and decided to build copies of the 4345, but I want to use the 2-inch 375 drivers instead of the 2421.If someone can give me any advice, recommend changes to the crossover scheme, I will be very grateful. With huge greetings to all participants! Gennady.
