I recently noticed a vibration in coming from the sub area of my Cambridge Soundworks T500's, I can easily & consistently reproduce this vibration using the THX 200-20 Hz crossover sweep tone. It occurs for ~1-2 secs during the early part of the sweep, ~5 secs after starting, and then is gone for the duration of the sweep. The low end of the sweep sounds fine. If I power off the sub amp there is no vibration during the test sweep. There are no loose screws, or other loose items on the outside of the speakers (I removed all the grills) that could be making this sound. Both the 10" powered and 12" passive sub look fine on inspection.
I was unable to locate the source of the vibration but it appears to be coming from inside the speaker enclosure to me. I am not sure if removing the sub would cause issues with the sealing of the enclosure so I did not want take it out without doing some research first.
My SVS PC13-Ultra will be delivered tomorrow
, and I was planning to run this in conjunction with the internal subs on the T500's in a front and rear configuration. It looks like CWS no longer produces the T500's and mine are ~4 years old so they are not covered by warranty any longer.
Thanks in advance.
