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.
Buy the Monoprice SSW-10. It is rated higher for sound quality than the RSL (Rogersound Labs) Speedwoofer 10S MKII and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
