I bottomed out my new VTF 3 MKII - Should I be concerned?


Please help me put my mind at ease. My pre/pro has some screwy settings when using its test tones. So when I initially set up my new sub the settings were way too high. Then when I put the bass cd from HSU in the CD player. The sub made, for the lack of a better word, a very loud farting sound for about 10 seconds before I could turn off the pre/pro. It sounded great with music at decent volumes today. Should I be concerned that I have damaged my new sub? Is there any way I can determine if I have done anything to it?

Thanks for any and all assistance!

Happy Holidays!

Give Hsu a call on Monday, but if you are now listening at proper levels and are not experiencing any problems, I am sure it is fine.

The VTF/STF 3 amps are very sensitive to input voltage and don't require a lot of output from your pre-amp/receiver.

Setting by ear will pretty much always have you ending up *HOT* (ie +5dB to 15dB loud).
An SPL meter is a pre-requisit for balancing your setup levels.

Its doubtful you have done any permenant damage as the driver can take a fair amount of punshment. But avoid it by being gentle especially with the BAS disk on track 1 with that loud deep sustained 16Hz organ going crazy. Its a TN1220 favorite.
