Offered here is a beautiful pair of JBL C50 Olympus S8R vintage loudspeakers,
one of JBL’s most celebrated large-format home speaker systems from the golden era of American high-fidelity.
The Olympus combined JBL’s legendary professional-grade compression-driver technology
with a large walnut-finished furniture-style enclosure and the distinctive hand-carved lattice grille.
The result is a speaker that is as impressive visually as it is sonically.
This pair has been carefully inspected, serviced as needed, cosmetically detailed,
and fully tested by HQaudios before sale.
Both speakers are operating properly and are ready to be enjoyed in a serious vintage audio system.
LE15A 15″ Woofer + PR15 Passive Radiator
375 Compression Driver + H93 Horn / L91 Lens + 075 UHF Driver
LX5 + N7000 Networks / 8 Ohms / 125W Continuous Program
High-Efficiency Design – Best for Medium-Large to Large Rooms
Professionally Restored & Fully Tested – 1-Year Warranty
Introduced during JBL’s classic era, the C50 Olympus was designed as a premium domestic
loudspeaker system using technology closely related to JBL’s professional theater
and studio components.
The S8R configuration represents one of the most desirable versions of the Olympus.
It combines a 15-inch JBL low-frequency driver with a matching passive radiator,
a large-format compression driver and acoustic lens/horn assembly,
plus JBL’s famous bullet-type ultra-high-frequency driver.
The sound is unmistakably classic JBL:
fast and authoritative bass, exceptional dynamics, highly present vocals,
powerful midrange projection, and clean extended high frequencies.
These speakers perform especially well with jazz, rock, blues, orchestral recordings,
vocals and classic analog sources where scale, dynamics and realism are important.
Low-Frequency Loading: JBL PR15 15″ passive radiator
Midrange: JBL 375 compression driver
Horn / Lens: JBL H93 horn with L91 acoustic lens
High Frequency: JBL 075 ultra-high-frequency driver
Networks: JBL LX5 + N7000
Nominal Impedance: 8 ohms
Crossover Frequencies: 500 Hz and 7 kHz
Please review our detailed photographs of the actual drivers, horn assemblies,
networks and cabinets included with this pair.
The Olympus produces the effortless scale for which large vintage JBL systems are famous.
Bass has weight and impact without sounding slow or overly soft.
The large-format horn system gives vocals, brass, guitars and percussion remarkable
immediacy and presence, while the dedicated JBL 075 high-frequency driver adds
air and detail to the top end.
With its high efficiency, the Olympus does not require extremely high amplifier power
to produce impressive listening levels and works particularly well with quality
vintage receivers, integrated amplifiers and tube amplification.
The C50 Olympus S8R is a high-efficiency, nominal 8-ohm system rated for 125 watts continuous program. It does not need large amounts of power to play at satisfying levels and pairs particularly well with tube amplifiers and quality vintage solid-state receivers and integrated amplifiers in the approximately 10–150 watts-per-channel range.
Because of its physical size and large-format horn system, the Olympus is best suited to medium-large to large rooms, where its scale and dynamics can develop fully.
Musically, this system excels with jazz, classic rock, blues, vocals, live recordings, and orchestral music – material where presence, dynamics, and realism matter most.
