Description
When a low-frequency driver blows mid-tour, you don’t need a workaround — you need the exact part the cabinet was engineered around. The Electro-Voice DL12BFH is the OEM 12″ replacement woofer built specifically for SX300E enclosures, restoring the cabinet’s intended output and tonal balance rather than forcing a compromise.
- Chassis size: 304.8 mm (12″)
- Max diameter: 309.6 mm (12.19″)
- Frequency response (-3 dB): 60 – 2500 Hz
- Sensitivity: 96 dB (1W/1m)
- Calculated max SPL/1m: 120.8 dB
- System power handling: 300 Watts
- Nominal impedance: 8 Ω (passive)
- Depth: 133.4 mm (5.25″)
- Net weight: 5 kg (11.02 lbs)
With a 96 dB sensitivity rating and 120.8 dB calculated max SPL at one meter, this driver has the headroom to keep pace with the low end of a full-range PA rig — whether you’re covering a club floor or filling out a monitor wedge feed. The 60 Hz to 2500 Hz response window matches the SX300E’s crossover design, so integration is straightforward: swap it in and the box behaves exactly as it did on day one.
For touring techs and rental houses stocking spares, this is the part number to keep on the shelf. It’s a direct fit, no re-voicing or crossover tweaks required, and it gets a compromised cabinet back into service before the next load-in.
