The "large volume" dual 8-inch VLF208LV features a low velocity port design that extends the frequency response while eliminating air noise through a heavy-duty 16-gauge steel perforated grille. With a frequency response down to 40Hz (-3dB) and an operating range to 30Hz (-10dB), the 1000-watt program VLF208LV stunningly delivers low end power from a compact size.
