Question: are jbl subwoofers any good?
Answer: One of the best features of the JBL GTO car subwoofers is the high sensitivity rating. With a 93dB sensitivity rating, the 12-inch car subwoofer is one of the most efficient subwoofers on the market. This means that if you sit 1 meter from the subwoofer and use 1 watt of power, the sub produces 93dB of volume output.
