[QUOTE="helotaxi, post: 355778, member: 550915"] Trying to use an unpowered sub as a passive radiator will at best sound bad. That being said, the original Speaker Warehouse Blazer that won the IASCA 0-100W category at the finals 4 times in a row had an enclosure for 4 iso-pairs of JL 10W5's that had a moveable baffle in it to change its internal volume. It was a custom flapper type valve that was gasketed and moved by a linear actuator, so it can be done, sort of. I think you will be better off directing your energy elsewhere to get better sound, i.e. getting a basic enclosure to the proper size to optimize the 10 rather than trying to complicate the problem.
