Generally, I prefer a sealed enclosure over vented. However, for either type, it all depends on how well the designer has executed his/her design, and how well the apes in production can stick to the blue print. Sealed enclosures are usually more forgiving of small variations in woofer/enclosure parameters. A LOT depends on the particular "Q" chosen for the design for either type. Like Carl says...listen for yourself. Now how about a WELL executed transmition line enclosure......? (check your furnace filters because there could be a lot of flying fur on that topic)
