I was just playing a few 20hz-20khz test tone to test response of my center channel (https://rbhsound.com/sv661c.php) and thought of playing a 10hz test tone to see the response and to my surprise, I could see the woofer cone moving. My center channel have rated freq of "55Hz-20kHz (±3dB)" and I was not expecting it to response 10hz frequency.
So, I want to ask:
1. does all speaker respond to freq beyond their rated frequency?
2. if above is true, what is significance of rated freq on product specs page.
My testing setup:
1. Source : Youtube on macbook pro(chrome)
2. Connection : HDMI
3. AVR : Denon 3600h
4. Speaker : RBH SV661C
It will good if other users can also share their test result if their speaker responds to freq below 20hz or outside the rated freq band.
