Review FOSTEX Electronic Crossover

The Fostex EN3020 is a high-performance crossover network designed for professional audio applications, particularly for use in loudspeaker systems. This crossover offers exceptional sound quality and precision, making it an ideal choice for sound engineers, live sound technicians, and installers seeking to create high-fidelity audio systems.

The EN3020 is a third-order, passive crossover network that features two independent channels, each with its own set of components. The low-frequency channel utilizes a second-order Butterworth filter with a slope of 12 dB per octave, ensuring a smooth and even transition from the woofer to the midrange driver. The midrange channel is a first-order Linkwitz-Riley filter with a slope of 6 dB per octave, providing a natural roll-off and seamless blending between the midrange and high-frequency drivers.

The EN3020 crossover is designed to work with a wide range of drivers and enclosures, making it a versatile solution for various audio applications. Each channel is equipped with high-quality, audiophile-grade components, including air-core inductors, polypropylene film capacitors, and metal-film resistors. These high-quality components ensure accurate and consistent frequency response, as well as excellent signal-to-noise ratio and low distortion.

The EN3020 crossover is housed in a robust, compact enclosure that is designed for durability and ease of installation. The PCB is protected by a layer of epoxy resin, safeguarding it against moisture, dust, and other environmental hazards. The screw terminals are large, gold-plated, and spaced to accommodate a wide range of speaker cables, making wiring and connection simple and secure.

In summary, the Fostex EN3020 is a professional-grade, passive crossover network that delivers exceptional sound quality and precision. Its versatile design, high-quality components, and rugged construction make it an excellent choice for a wide range of audio applications, from live sound reinforcement to studio monitoring systems.

The Fostex EN3020 is a popular passive crossover network used in various DIY and professional audio projects, particularly for building high-fidelity loudspeakers. This crossover offers several advantages and disadvantages.

1. High-quality components: The EN3020 utilizes premium components, including air-core inductors, iron-powder resistors, and polypropylene capacitors. These components contribute to improved sound quality and better frequency response.

2. Adjustable design: The crossover is fully adjustable, allowing users to fine-tune the frequency response and phase alignment of their loudspeaker system. This flexibility is beneficial for achieving optimal sound performance.

3. Robust construction: The EN3020 features high-quality PCBs and a rugged, metal enclosure. This construction ensures reliability and durability, making it suitable for professional applications.

1. Complexity: Due to its adjustable nature and high-quality components, the EN3020 may be more challenging to set up and fine-tune compared to simpler, fixed crossovers. This complexity may intimidate some users.

2. Cost: The premium components and robust construction contribute to a higher price point compared to other crossover options.

3. Size: The EN3020 is a larger, more substantial crossover, which can make it more difficult to integrate into smaller speaker enclosures or projects with limited space.

The Fostex EN3020 crossover offers several advantages for those seeking high-fidelity sound and the ability to fine-tune their speaker system. Its premium components, adjustability, and robust construction make it a solid choice for professional and advanced DIY audio projects. However, its complexity, cost, and size may make it less appealing to those with simpler requirements or limited budgets or space.

If you're looking for a high-performance, fully adjustable crossover for a professional or advanced DIY audio project, the Fostex EN3020 is an excellent choice. Its premium components and robust construction contribute to improved sound quality and reliability. However, if you're working on a smaller project, have a limited budget, or prefer a simpler setup, you may want to consider alternative crossover solutions.

Details:

The output level controls, provided for each frequency range, are ID step attenuates which mute the signals at OFF position. The model EN 3020 can be used in 2-way and 3-way modes of stereo up to 4-way mode mono, each frequency range is indicated by an LED. Both a balanced floating Cannon XLR type connector and an unbalanced phone jack are provided for all inputs outputs. Either 12dB/octave or 18dB/octave can be selected for the filter and at each point of crossover frequencies, six types to match speaker.

By the use of these controls, uniform sound pressure characteristics can be set up in a short time. The summing characteristic voltage at each crossover point is designed to be flat when the phase matched. The rear panel phase selecting switch conveniently allows simple matching of and also serves to compensate for sound time delay between speaker units. Also, an optional protective cover Type P3020, to prevent accidental disturbing of the front panel settings, is available.

In the stereo 2-way mode, a 3D output for super woofer can be obtained.
