LORDWORLD 2.5" 4 ohm full-range speaker streaming audio

2.5-inch 4-ohm full-range driver

This single 2.5-inch 4-ohm full-range speaker is built for Hi-Fi enthusiasts who want a compact driver for desktop or custom audio projects. It covers an effective frequency range of 150Hz-20KHz to deliver balanced sound across the spectrum. The unit is sold individually for stereo pairs or mono centre-channel use. It suits builders comfortable wiring their own amplification and crossover networks.

88dB sensitivity 8-15W power handling

With a sensitivity of 88dB and a rated power handling of 8W-15W, the driver produces loud, crisp output from modest amplifier power. The high sensitivity keeps thermal load low during extended listening sessions. As a passive component, it adds no fan noise or electrical hum of its own. Heat dissipation depends entirely on the enclosure design and amplifier matching chosen by the builder.

45mm height 67mm diameter 73mm screw spacing

The driver measures 45mm in total height with a largest diameter of 67mm and a 61mm cut-out hole for flush mounting. Four mounting holes sit on a 73mm screw diagonal with a 52mm angular spacing for secure attachment to baffles or panels. Its shallow profile frees internal cabinet volume for port tuning or additional damping material. Builders must supply an amplifier, crossover components and a suitable enclosure to complete the system.
