Short answer: the KEF KC62 for a tiny sealed cabinet, the Klipsch R-121SW for a conventional 12-inch driver. The KC62 packs dual 6.5-inch force-canceling drivers and 1000W into an ultra-compact basketball-sized sealed enclosure. The R-121SW uses a 12-inch spun-copper driver with 200W RMS and delivers controlled, musical bass with minimal distortion, and it costs $1,189.96 less.
Buy the Klipsch R-121SW. It is rated higher for sound quality than the KEF KC62 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
