Louder than anything this small.
Smaller than anything this loud.

The KF Series (comprising the 300, 700 and new 800 range) is a premium family of pointsource and linesource loudspeakers boasting a very high output to size/weight ratio. The series features exceptional pattern control due to symmetrical design, large horn and spaced woofers. Superior performance in a very easy-to-work-with package.

Designed for an extremely wide range of touring and installed applications, the KF Series delivers a scalable solution for corporate A/V events, small-to-medium-sized live sound reinforcement, performing arts venues, houses-of-worship, retail spaces, ballrooms, theaters, theme parks and more.

The vertical directivity of every arrayed system conforms to the curvature of the array while the symmetrical design of every module provides absolute uniformity over the horizontal coverage area and spectacular imaging when used in stereo. The addition of EAW Focusing processing provides the hallmark level of clarity and detail for which EAW systems are known.

Unique EAW core technology PLUS NEW Isophasic waveguide.

The EAW KF Series incorporates a number of unique core technologies including:

  • Phase Aligned LF
  • Symmetry of Sources
  • Concentric Summation Array (CSA)

The new KF810P loudspeaker with Isophasic waveguide technology(Patent Pending)

EAW’s latest tech breakthrough transforms the acoustic input source to a true Isophasic output.

  • No internal acoustic reflections or distortions
  • Focused pattern control with maximum acoustic gain

Designed in the EAW engineering laboratory in Whitinsville, Massachusetts, our USA patent pending, Isophasic Waveguide with a Tri-ovular Bi-lens Conoid™ Phaseplug is a new development in the field of acoustic research. The innovative waveguide equalizes the path length from the transducer to the exit to achieve isophasic output that intrinsically controls the vertical and horizontal pattern.

Perfect companion products and accessories make everything easier

The KF Series of loudspeakers is fully compatible with our SB range of subwoofers and is ideally matched to our UXA amps. Simply select the one that is right for your project then assemble. We’ve made all the pieces including flybars and adapter bars to set up your rigging configuration – simply and quickly.

Software tools

Every EAW product series works seamlessly with our array of software applications designed to make installation easier and sound optimisation a more exact science.

EAW Resolution 2.7™, for example, is a powerful and easy-to-use simulation software that accurately predicts the performance of multiple arrays within a venue. Driven by EAW’s proprietary Resolution acoustics modeling software, Resolution is more accurate and powerful than previous generations of software by utilizing measured 3D acoustic data.

Output levels are displayed by varying color using a variety of methods, including 1/3-octave and broadband SPL, A and C weighted. The actual frequency response at any point in a venue can also be viewed. User-defined environmental conditions, specifically temperature and humidity, are factored into these calculations.
