 Hi Rodny
What sort of levels dB(C) were you running at to hear noise at 10hz?
Was this on sinewaves? I'm wondering if the signal you were feeding it had heavy distortion which produced an audible harmonic.
I ran my IB array at 10Hz up to nearly 100dB(C) (uncorrected RS meter) using REW in the "Frequency follows cursor" mode.
The IB was completely silent though the room was shaking violently. I stopped at about 1/4" cone movement because I feared the windows would break if I pushed it any harder.
Are you sure your box or something else isn't vibrating in sympathy somewhere? |
It was about 90dbs with only one side, the signal was from the REW sine waves, I was using the RS meter, and yes the house made some real loud noises:holycow:
I went back and listen to the subs at 10Hz and one of the subs its making a noise, its like the aluminum cone rubbing on something
, if I have time this weekend I will check all the subs, it could be a speaker wire behind the sub.
