Why the JBL 4425 Is Notable

The JBL 4425 was designed as a compact professional studio monitor using JBL’s
Bi-Radial horn technology to provide controlled high-frequency dispersion.

Its two-way architecture combines the 2214H low-frequency driver with the
2416H compression driver and 2342 horn, crossing over at approximately 1.2 kHz.

Front-panel level controls allow adjustment of the mid- and high-frequency balance,
making the 4425 suitable for both critical monitoring and high-quality home listening.

HQaudios Inspection, Service & Testing

This pair has been professionally inspected, serviced, and fully tested by HQaudios.

Our technicians inspected the low-frequency and compression-driver assemblies,
checked electrical connections, performed driver resistance measurements,
and completed functional sound testing on both speakers.

Technical photographs in the product records show JBL 2214H low-frequency drivers
and 2416H compression-driver components consistent with the factory 4425 specification.
Specific component-level replacement is stated only where supported by documented service records.

Technical Condition

Both speakers have completed HQaudios functional testing and are offered as an operating stereo pair.

Driver assemblies were inspected and electrical resistance measurements were recorded
during technical evaluation.

Individual driver DC-resistance measurements are diagnostic measurements and should not
be interpreted as the complete system’s nominal impedance.

Cosmetic Condition

This pair presents well with walnut-finished cabinets, black front baffles,
JBL Bi-Radial horn assemblies, and dark-blue grilles.

Normal age-related wear remains visible in areas such as the rear panels,
cabinet surfaces, front baffles, driver surfaces, hardware, and other details
consistent with vintage use.

Please review all product photographs carefully.
The photographs show the actual speakers and form an important part of the cosmetic description.
