I have a chance to acquire the mini Valencia looking Madrid cabinets (empty) with the lattice grills. My question: I have a set of N500 crossovers and 511b/802 drivers. Would a 416 woofer work well in these cabinets as a bass bin crossed at 500Hz. There is a small square cut out above the 15" woofer cut out in the cab- so it wouldn't be a sealed enclosure. These would look like mini A-5s and would be very much eye candy. But would they be ear candy? Inside dimensions of the cab is 18 3/4" x 20 1/4" x 15 1/2". Any help appreciated. Thanks in advance
