Short answer: the Klipsch RP-1000SW. Both are rated 3.6/5 for sound quality (#142 and #125 of 212 subwoofers), and the Klipsch RP-1000SW costs $674.99 against $769.95 for the JBL L10cs Classic, and with sound quality even, the cheaper one is the better buy.
What the JBL L10cs Classic does well: 10-inch down-firing ported with 250W delivers strong solid musical bass with rock-solid bottom end.
Why pick the Klipsch RP-1000SW: The entry 10-inch model in Klipsch’s flagship Reference Premiere high-excursion subwoofer family. The catch: The 10-inch driver naturally gives up bottom-octave (16-25Hz) maximum output compared to the 12-inch Klipsch RP-1200SW and 14-inch Klipsch Reference Premiere RP-1400SW in larger home theater rooms.
Buy the Klipsch RP-1000SW. Both are rated the same for sound quality, and it costs $94.96 less than the JBL L10cs Classic.

Klipsch RP-1000SW: $674.99 each Amazon eBay
Same family: the Klipsch RP-1200SW (larger subwoofer, ranked higher, rated 3.8/5), the Klipsch Reference Premiere RP-1400SW (larger subwoofer, estimated 4/5) and the Klipsch RP-1600SW (larger subwoofer, rated 4.2/5).
Pros: The entry 10-inch model in Klipsch’s flagship Reference Premiere high-excursion subwoofer family. Combines a newly developed 10-inch front-firing spun-copper Cerametallic driver with an analog preamp stage and 300W RMS / 600W peak Class D amplifier. Features Klipsch’s internal flare Aerofoil slot port that eliminates port chuffing and turbulence at high velocity. CEA-2010 output data confirms robust output across the 31.5Hz to 80Hz range with extension reaching 19Hz in-room, providing tight, articulate musical punch with excellent transient speed.
Cons: The 10-inch driver naturally gives up bottom-octave (16-25Hz) maximum output compared to the 12-inch Klipsch RP-1200SW and 14-inch Klipsch Reference Premiere RP-1400SW in larger home theater rooms. The cabinet depth (534 mm) is substantial for a 10-inch sub.
