I pretty much stole the cabinet from the Klang/Tong Nada if memory serves. Quite a large cabinet really. However, I deviated in my crossover design from normal practice by NOT making measurements quasi anechoic but in-room for the bass. As a result the room gain was taken into account then. Even so, I still think I should have considered a smaller cabinet for a bit of low end punch. Nothing I can't fix with EQ and proper placement though. 😁
