More Power for the Price
The XLC 21300 amplifier sets a new benchmark of power capability for Crown's cost-conscious XLC Series, delivering 1,000W at 8Ω and 1,300W at 4Ω; the XLC21300's high power output provides an affordable solution to drive subwoofers at both 8Ω and 4Ω loads.
Versatility and Value
The XLC 21300 is designed to integrate with a range of sound system configurations, supporting parallel, input Y and bridged-mono-output modes. Its HD-15 input allows simple connectivity with the JBL CPi2000 cinema processor, which provides audio enhancement including DSP, room EQ tuning, volume control and system fault detection. Add JBL Cinema Expansion Series speakers and subs to build a complete, fully integrated JBL cinema sound solution.
Monitoring and Diagnostics
Accurate diagnostics help keep your system running at peak performance: The XLC 21300 monitors the status of amplification and speaker loads through third-party control and TMS systems when used with the JBL CPI2000 processor; front-panel indicators monitor key statistics such as Signal, Clip, Power, Bridged Output and Fault; a Power LED indicates standby, normal operation and default.

New, this amplifier was priced around US$1,822, with recent used examples near US$880–US$1,000, so US$940 is broadly fair rather than a bargain. Your comparable data puts it well above the US$286 median and above the US$600 75th percentile, making the price somewhat ambitious unless the unit is especially clean or comes with useful installation hardware.
The appeal is serious, clean power: 1,000 watts per channel into 8 ohms, 1,300 watts into 4 ohms, plus stereo, parallel, and bridged-mono modes. It is particularly well suited to cinema speakers and demanding subwoofer duty, with forced-air cooling and built-in monitoring/diagnostics. At this money, confirm both channels deliver rated output, the fan is quiet and healthy, the rear controls and barrier-strip connections are intact, and verify the mains voltage—some versions are specified for 230V operation.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Crown Audio traces its origins to 1947 in Elkhart, Indiana, where minister and radio enthusiast Clarence C. Moore, alongside his wife Ruby, founded the International Radio and Electronics Corporation (IREC) in a converted chicken coop. Initially focused on rugged open-reel tape recorders for missionaries in remote regions, the company pioneered innovations like the world's first tape recorder with a built-in power amplifier in 1949. Ruby's suggestion in the 1960s led to the adoption of the Crown name, inspired by the crown emblems on their 'Royal' and 'Imperial' models, with the corporation officially renaming to Crown International, Inc. in 1975.
The brand shifted from tape recorders and compact loudspeakers in the 1950s to standalone tube power amplifiers by 1959, cementing its expertise in professional amplification. Crown became renowned for groundbreaking products like the DC300 in 1968—the first high-power solid-state amplifier—and the M600/M2000 in 1972, featuring patented technologies such as the ground-bridge circuit. Today, under Harman International since its 2000 acquisition, Crown specializes in high-output amplifiers for touring rigs, cinema venues, installed systems, portable PA, and commercial audio, prioritizing reliability and innovation over consumer categories like speakers, turntables, DACs, headphones, or cables.
Crown holds a commanding position as a pro-audio powerhouse, trusted by industry leaders for its durable, high-performance amplifiers that define live sound and installation standards. Far from high-end audiophile or vintage collector fare, it dominates the professional market with over 75 years of technical milestones, though recent production shifts to Mexico reflect ongoing evolution. For the discerning hi-fi buyer eyeing pro-grade power, Crown delivers uncompromised authority.
