Emilar EA 175-8 high-frequency compression driver. Tested working.

Vintage and working driver.

The Emilar Corp EA 175-8 is a vintage high-frequency compression driver known for its professional-grade build and audiophile-leaning sound profile. Originally manufactured in Anaheim, California, during the 1970s, it was designed as a high-quality alternative to contemporary drivers from Altec and JBL.

specifications for this driver are:

• Power Handling: 175 Watts.
• Impedance: 8 Ohms.
• Throat Diameter: 1-inch.
• Frequency Response: 500 Hz to 15,000 Hz.
• Mounting: 2-bolt mounting pattern (similar to Altec Lansing standards).
• Magnet Type: Often features an Alnico magnet in the EA-series, which is highly prized by vintage audio collectors for its perceived natural and "lush" sound compared to ferrite alternatives.

• Sound Quality: It is often described as having a "lush" and "articulate" midrange. Some users find it more extended than Altec drivers, excelling at reproducing complex, dense instrumentation and intimate vocal details.
• Application: While engineered for vocal sound reinforcement and instrument amplification, it is frequently used in high-end DIY 2-way monitor systems.

Emilar was founded by former Altec Lansing and JBL engineers, including Jonas Renkus. Consequently, the EA 175-8 shares significant "DNA" with these brands, often fitting the same horn flares and being used as a drop-in upgrade or alternative in Altec-style systems.
