Efficiency Bandwidth Product, defined by Small as Fs/Qes and is used as a rule of thumb for enclosure selection. EBP values under 50 suggest the use of a sealed enclosure. EBP values over 100 suggest the use of a vented enclosure. Drivers with EBP values between 50-100 are adaptable for use in either type of enclosure.

The efficiency bandwidth product (Fs/Qes)

Efficiency Bandwidth Product. A guide that helps a designer determine whether a driver is more suitable for a sealed or ported enclosure. EBP of less than 50 indicates the driver should be used in a sealed, 50 - 90 indicates flexible design options, over 90 indicates best for a ported enclosure. EBP = Fs / Qes

Exhaust BackPressure sensor Feedback input; PCM uses this to monitor and control EPR operation; 5.0 volts in, 0.8-1.0 volts/14.7 psi KOEO or at idle, increases with engine RPM/load, decreases as altitude increases. PID: EBP (pressure), EBP V (volts)

Electronic Bill Presentment. The electronic delivery of vendor requests for payment. Vendors send consumers their bills via PCs, telephones or screen phones.
