Question: have any users of high output subs suffered any home damage as a result? My new SVS doesn't have me concerned for the structure of the house but......There is a plaster stucco ceiling on the room underneath my 'boom boom' room. It has hairline cracks, but they've been there for a long time (and I can't see any enlarging of them after pumping the Haunting at reference). Am I in danger of causing the plaster to relocate to the floor? Has this type of situation happened to anybody else? My roomate, who owns the house, says that he doesn't care, but all things considered, I'd rather not have to clean up the mess.
