    I read somewhere (don't recall where) that putting a prolonged sine test tone through a sub can damage the driver. I use DVE to calibrate, and am concerned that the "rattle" test is using a sine waveform, so I am hesitant to crank it to locate rattles caused by my new toy (my new SVS.... my precious... ). My question is, how long of exposure is too long?

    Sorry not much of an expert here, but aren't you suppose to do that at only between 75db and max 85db only and I guess it'll only be for a few minutes only to plot your graph of less than 20hz right up to 100 hz in 5 hz increments(or is it 10 hz increments). I am sure your SVS can withstand the punishment for a while anyway.

    I believe that what you should be afraid of is the sub bottoming out(which usually sounds like a loud Clack) where the driver is literally hitting metal.


    PS. I got these from reading the SVS sub manual.
