The R1 10" marine subwoofers have a truly versatile design that will outperform in an infinite baffle configuration, as well as being suited for sealed and ported enclosures. These subs will handle 250 watts RMS and have an excellent low-end extension. For a little extra flash, the R1 10" grill option has built-in RGB LEDs that backlight the cone to create your desired visual atmosphere. All of this is packed into durable marine-grade plastic housings that need just over 5" of mounting depth, giving you ample placement possibilities. The only limit is your imagination.
