KF364 3-Way Full-Range Loudspeaker System

Product Overview

The EAW KF364 is a 3-way full-range loudspeaker, representing a significant addition to the legendary KF Series. It delivers high output and versatility within a compact package. Key features include high-quality neodymium drivers, a coaxial MF/HF section, and a sophisticated crossover network housed in a flexible enclosure. The KF364 is designed for both portable use and fixed installations, offering M10 mounting points. It can be fitted with trim plates to conceal handles and includes U-bracket mounting points. Optional height-adjustable legs are available for stage monitor configurations. When paired with the UX8800 processor and EAW Focusing, the KF364 provides exceptional performance for any scenario.

Features

Graph Descriptions

The following graphs illustrate the performance characteristics of the KF364:

Frequency Response (Processed, Multi-amp)

This graph shows the frequency response of the loudspeaker when processed for multi-amplification. Curves represent Low Frequency (LF, green), High Frequency (HF, black), and the Overall response (blue), measured from 64Hz to 20kHz.

Frequency Response (Unprocessed)

This graph displays the frequency response without any signal processing. Curves represent Low Frequency (LF, green), High Frequency (HF, black), and the Overall response (blue), measured from 64Hz to 20kHz.

Impedance

This graph illustrates the impedance of the loudspeaker across frequencies. Curves represent Low Frequency (LF, green), High Frequency (HF, black), and the Overall impedance (blue), measured from 64Hz to 20kHz.

Phase Response: Linearity

This graph shows the phase response, indicating the linearity of the phase shift across frequencies, measured from 64Hz to 20kHz.

Beamwidth (-6 dB SPL Point)

These graphs show the beamwidth at -6 dB SPL points. The orange line represents the horizontal beamwidth, and the black line represents the vertical beamwidth, measured from 64Hz to 20kHz.

Enclosure

Dimensions

Detailed mechanical drawings are provided showing front, side, top, and bottom views with key dimensions in millimeters. The overall dimensions are approximately: Height 648mm, Width 435mm, Depth 387mm. The bottom features a standard 35mm stand mount hole.

Notes

Polar Data

The polar data illustrates the directivity of the KF364 loudspeaker across various frequencies. Plots are provided for both horizontal and vertical planes.

Horizontal Polar Patterns

These plots show the sound dispersion in the horizontal plane at different frequencies (from 100Hz to 16kHz). At lower frequencies, the pattern is generally omnidirectional, becoming more focused and directional as the frequency increases.

Vertical Polar Patterns

These plots show the sound dispersion in the vertical plane at different frequencies (from 100Hz to 16kHz). Similar to the horizontal patterns, directivity increases with frequency.

Input Panel and Signal Diagram

Input Panel

The input panel features Neutrik connectors. The product is equipped with M10 mounting points for installation.

Signal Diagram

Two primary signal configurations are illustrated:

3-Way, Single-Amp (LF/MF/HF)

In this configuration, a single amplifier channel drives all three frequency bands (Low, Mid, High) through a crossover network (XVR) which includes passive Low-Pass Filter (LPF), High-Pass Filter (HPF), and Equalization (EQ).

3-Way, Bi-Amp (LF, MF/HF)

This configuration uses separate amplifier channels for the Low Frequency (LF) driver and the Mid/High Frequency (MF/HF) drivers. The MF/HF section utilizes a crossover network (XVR).

Legend

• DSP: EAW UX8800 or NT internal Digital Signal Processor.
• HPF: High-Pass Filter, used for crossover or set to recommended values.
• LPF: Low-Pass Filter, used for crossover.
• LF/MF/HF: Denotes Low Frequency, Mid Frequency, and High Frequency bands respectively.
• AMP: Represents an appropriate power amplifier.
• XVR: Crossover network, typically including passive LPF, HPF, and EQ.
• EAW FOCUSING: Indicates the use of DSP with EAW Focusing technology.
