Components and construction
- 4.5-inch (E 4.5) / 5.25-inch (E5) / 8-inch (E8) Kevlar® low-frequency transducer
- 1-inch (25 mm), ultra-low-mass, silk-dome, high-frequency transducer
- Front-firing acoustic port for superior bass-frequency reproduction
- Optimized, resonance-suppressing internal bracing
- 100 dB (E4.5) / 102 dB (E5) /105 dB (E8) maximum continuous SPL
User controls
- HF Driver Adjust (±6 dB, continuously variable)
- Midrange Driver Adjust (±6 dB, continuously variable)
- Acoustic Space settings (flat, -2, -4 dB) for accurate mixing contour
- Highpass filter (Off, 80 Hz, 100 Hz)
Power and safety
- 50 (E4.5) / 70 (E5) /130 watt (E8), Class AB biamplification
- RF interference, output current limiting, over-temperature, transient, and subsonic protection
- Amplifier “soft start” feature eliminates popping on power-up
- Internal power supply with IEC connector
- Power switch with on/off LED
Inputs and outputs
- Balanced XLR/¼-inch and unbalanced RCA inputs (E5/E8)
- Balanced ¼-inch TRS and unbalanced 1/8-inch TS, RCA inputs (E4.5)
- 1/8-inch stereo headphone output (E4.5)
