This listing is for a matched pair of JBL 3120 passive crossovers in very good condition, set with a crossover frequency of 1.2 kHz. Designed for dependable two-way frequency division, the 3120 routes low and high bands cleanly to the appropriate drivers, helping restore or optimise the performance of compatible passive loudspeakers. If you’re servicing classic JBL cabinets, building a custom enclosure, or replacing ageing crossover networks, these proven units offer a straightforward path to balanced, musical results. The 1.2 kHz split suits many common woofer/horn combinations, making integration practical for both refurbishment and DIY projects. Built to JBL’s robust standards, the 3120 delivers stable operation and consistent voicing, supporting clear mids, smooth HF, and controlled LF handover when paired with suitable components. Supplied as a pair, they’re ideal for stereo systems or twin cabinets that need matched networks. A practical, cost-effective solution for bringing passive PA or install speakers back to reliable working order. Typical use: refurbishing JBL boxes, service replacements, and custom passive builds.
