I did both. Bought the Madisound cabinets and built them exactly to spec with the MUndorf Silver/Oil Capacitor. I also had a pair of cabinets built from 1" Baltic Birch, no port and a much more sophisticated crossover as used in the World Designs WD26 which uses the same woofer and a less expensive SEAS tweeter. The birch pair with the crossover outperformed the simpler A26 by a large margin.
