Rockville RBG18S 18' 2000W Active Powered PA Subwoofer W/Dsp+Limiter Pro/DJ

  • Built-in Amplifier - With a MOSFET power supply you get improved switching speeds, better performance with less power from the driver, lower gate-to-drain feedback capacitance, lower thermal impedance for higher switching frequencies.
  • Variable Low-Pass Filter - A low-pass filter is an electronic circuit that removes all the notes above the filter's frequency setting. You will use the Low-pass filter to primarily keep high notes out of your subwoofer(s).
  • High Level Inputs - Speaker level inputs are commonly referred to as high-level inputs. It will be used to connect the LOPRO10 to your factory radio or an aftermarket radio that does not have low-level (RCA) inputs.
  • Low-Level Inputs - Line level inputs (RCA inputs / low-level inputs) use RCA interconnect cables to link the LOPRO10 with the source unit. Most aftermarket radios have multiple pairs of RCA outputs that can connect to multiple amplifiers.
  • Variable Bass Boost - Variable Bass Boost allows you to adjust the low bass within the boost range to just the way you like it.
  • Specs – 15.5” x 11” x 3”. If you are short on space, this is a great solution for you. The combination of amplifier and subwoofer all into one, makes this ideal for spatially challenged vehicles. Weight: 13 lbs..
