Product review of BFB, 'These circuit boards make it easy to layout and construct a clean functional crossover. Shipping and service are first rate from Madisound. They even refunded and overage on postage. Don't know of any other company that does that. It cost a bit but the crossovers have a really professional look and feel. It is important to note that this board comes with 3/16" spade connectors and not the more standard 1/4". If you do not have any you might consider ordering. I am very happy with the results.'
