PRV AUDIO EX3.5 Stereo Car Audio Crossover - Precise 2/3 Way Tuning

In this review the PRV AUDIO EX3.5 crossover is examined for drivers and audio enthusiasts who want more control over their car sound without a complex DSP. The bottom line: this is a straightforward, analog-style stereo crossover that lets you shape frequency bands and add sub bass while keeping installation and tuning approachable. It is best-valued for those who want a reliable hardware crossover to split signals into 2-way or 3-way systems and to fine tune high pass, low pass and sub output levels.

Key Features

• Wide filter adjustment: The EX3.5 provides a broad frequency range of filter settings so users can dial in precise crossover points for clear separation between speakers.
• Flexible I/O: Two or four RCA inputs and six RCA outputs support both 2-way and 3-way configurations, offering adaptable connectivity for many car setups.
• Adjustable filters: Three-way adjustable high pass and low pass filters allow tailored band control to match speaker capabilities and improve overall clarity.
• Output level and bass boost: Independent output level controls and an adjustable bass boost on the Sub Out let users balance levels and add low-end punch where needed.
• Channel control: Quick on/off switches for each channel make it simple to isolate or mute individual bands during tuning or troubleshooting.
• Butterworth slope: The 12 dB/octave Butterworth crossover slope delivers smooth transitions between frequency bands for natural-sounding results.

Who It's For

The EX3.5 is designed for car audio hobbyists and installers who prefer a hardware crossover to control frequency splits without relying on digital processing. It suits systems that need clear separation for mids, highs and a dedicated sub channel, and works well when paired with aftermarket amplifiers.

Its less suitable for users who require advanced time alignment, parametric EQ or digital signal processing features; those buyers should look to a DSP solution. Also, if a fully integrated touchscreen tuning workflow is required, this units analog controls may feel basic by comparison.

Pros & Cons
