The RMA 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. All of this is packed into durable marine-grade plastic housings that need just over 5" of mounting depth, giving you ample placement possibilities. Pairs perfectly with our R1 1000.1 Marine Amplifier.
