JBL JRX118S

The JRX118S is an 18" compact direct-radiation subwoofer designed to supplement and extend low frequency performance of full-range systems in live sound and music playback applications. It is an excellent choice for use with powered fullrange speakers or in systems using powered mixers. The JRX118S is driven by a massive JBL 18" woofer with a cast frame and 3" voice-coil. It’s rated at 350 watts (continuous) and 1400 watts (peak) – based on JBL Professional’s 100 hour extended life test.

Key Features:

• 18" compact subwoofer
• 300 watt (continuous), 1200 watt (peak) power capacity
• The rugged enclosure is constructed from 19 mm (¾ in) MDF (Medium Density Fiberboard) using advanced adhesives and mechanical fastener technology for durability and improved low-frequency performance. The enclosure is covered in black carpet.
• A top mounted, cast aluminum 35 mm pole mount receptacle can receive an optional SS3BK pole to facilitate use of the JRX118SP as a base for a midhigh speaker cabinet.
• High-voltage capacitors and inductors with massive cores and heavy gauge wire enable the crossover network to handle high power without saturating.
• Non-resonant, all steel handles are used.
• Attractive 18-gauge perforated steel grille protects components from damage.
• 35 mm pole mount receptacle for use with satellite speakers.
