Short answer: the RSL Speedwoofer 10S MKII for output, the SSW-10 for a slim footprint. Both are 10-inch subs, but the RSL is a ported design with 400W RMS (1020W peak) from its XDR amplifier. The Monoprice SSW-10 is sealed and ultra-slim at just 7” tall, with 150W RMS and a 108.2dB average, so pick it only when the shallow cabinet matters more than headroom.
The case for the Monoprice SSW-10: 10-inch ultra-slim sealed (7” height) with 150W RMS, 108.2dB average.
What the RSL (Rogersound Labs) Speedwoofer 10S MKII gets right: 10-inch ported with 400W RMS (1020W peak) XDR amplifier.
