This is NOT a sub-woofer test. This is a speaker low-frequency test. This test will not, and does not work with sub-woofer. Sub-woofers in virtually every modern audio system has its own channel. It's the ".1" in a "5.1" or "7.1" system. This audio is NOT sent to the sub-woofer .1 channel and does not test, nor work with sub-woofers as typically employed.
