Speaker driver specifications
274 drivers: 1 Beyma, 2 EAD, 1 Eminence, 4 FaitalPRO, 110 SB Acoustics, 22 SB Audience, 54 SEAS, 75 Scan-Speak, 1 Vifa, 4 Wavecor. This reference lists the complete dataset without requiring JavaScript. Use your browser’s Find command to locate a model.
T/S parameters use the linked manufacturer datasheets. Dimensional sources and exceptions are noted for each model. A dash means that a value has not been included. Check the linked drawing before cutting a baffle. Calculations use one driver; real builds need measurements.

Nominal size: Hifi Kit product specifications. Outer diameter, basket diameter and mounting depth: manufacturer drawing. Allow clearance when specifying the baffle cutout.
Two 16-ohm voice coils connected in parallel: 8 ohms nominal. All T/S values and enclosure calculations use the datasheet’s 8-ohm column; do not use these values for a single coil or series wiring. Sensitivity is specified at 2.83 V / 1 m over 300–1000 Hz. The datasheet’s dynamic mass Md is not entered as Mms.
