JBL Factory Replacement Driver 2408H-2 - Direct Fit Speaker Driver

In this review of the JBL Factory Replacement Driver 2408H-2 the bottom line is simple: if you need a direct, OEM-style replacement for compatible PRX series speakers, this driver delivers reliable performance and straightforward installation. It is aimed at technicians and owners who want an exact factory-style swap rather than a repair of internal parts, because the unit is a complete driver that replaces the whole assembly rather than allowing a diaphragm change. The reviewer found it practical for bringing aged or damaged high-frequency sections back to factory specification.

Key Features

• Factory fit: Designed as the OEM 2408H-2 replacement so it installs cleanly into compatible PRX-700 and PRX-800 enclosures without modification.
• Complete driver: Supplied as a brand new complete driver, which simplifies replacement because there is no separate diaphragm to swap.
• Compact size: At about 2.5 in wide by 2 in tall, the driver fits the limited space used in many JBL horn assemblies.
• Electrical match: With an 8 ohm impedance and a DCR of 4 ohm this driver maintains the original crossover and system behavior when installed.
• Threaded mount: Uses a 1-3/8 in thread-on connection for secure installation into threaded horn assemblies.
• Part verification: Labeled as part 5020337X and clearly marked 2408H-2 so buyers can confirm compatibility before ordering.

Who It's For

This replacement is for audio technicians, venue maintenance staff, and owners of JBL PRX-700 and PRX-800 series speakers who need a faithful, factory-style high-frequency driver swap. It suits situations where the original driver has failed or shows wear and the goal is to restore the cabinet to its original acoustic character.

It is not for someone wanting to repair a diaphragm or perform parts-level servicing, since the unit does not have a replaceable diaphragm. Also, buyers should double-check they need the 2408H-2 model and not the similar 2408H to avoid fit or sonic mismatches.

Pros & Cons

Pros

• Direct factory replacement that restores original speaker behavior without modifications.
• Easy to install with a 1-3/8 in threaded mount, making field service faster.
• Good build quality and electrical match for PRX series systems, preserving crossover performance.

Cons

• Does not have a replaceable diaphragm, so a full driver swap is required rather than a lower-cost diaphragm repair.
• Not identical to the 2408H model, so ordering the wrong model will lead to compatibility issues.

Our Verdict

The JBL 2408H-2 replacement driver is a practical, no-nonsense option for anyone restoring PRX-700 or PRX-800 series speakers to factory condition. It is good value for technicians who prefer a direct OEM-style swap and want reliable electrical and mechanical compatibility, but buyers must confirm the 2408H-2 is the correct model for their cabinet since the diaphragm cannot be serviced separately.
