The only way way to crack the tank is if the subwoofer was creating a pressure inside the tank and it was airtight. The only way the pressure could relieve itself is if it cracked the tank. Don't you guys watch mythbusters on Discovery? They tried it with a subwoofer in the car and couldn't get the glass to crack because the air found ways out. No worries on this one.

Thats true but they used too large a wave. They used a driver that was like 5 feet across and it did not hold up in the test. I have done SPL contests. Thats where people who will one day be deaf come to compete the the amount of Sound Pressure Level they can create with there subs and amps.

I have seen several windshields and rear windows pop out.

Yes they popped out due to air pressure and not frequency. But I have also seen a singer break a glass with her voice. The military has also tested sound waves as a weapon. While I dont think you can turn up your subs and break your tank. I do think that you can freak out the fish or vibrate the rocks and make them topple if they are not secure.

Heck when I get my theater going the dresser upstairs vibrates.

Last night my dad came home from work in miami, so I figured I would test out the sub for him. I threw in the SACD of Pink Floyd's Dark Side of the Moon, and on the first track, the heartbeat intro was shaking the picture frames around the living room, but at first I just thought it was part of the music... And that was with the sub's gain turned down to 30%ish....

Has/does anyone worry about their tanks cracking from too loud a sub? Anyone with a loud sub close to their tanks? I'm interested in hearing what others think.

Thanks

a buddy of mine has two salt tanks, he is also a home theater nut. Everytime i go over his house he has me sit in the "drivers seat" to feel how loud the new system upgrade is. He has a couple of subs in his living room alone. If anyone would break a tank from a loud woofer it be him. Never had any problems.

BTW they're in the same room aswell.
