The K700 Pro is the flagship studio model of Ken Kreisel that utilizes an eight-driver line array design with 3D Push-Pull-Pulsar patented technology. The K700 Pro is perfect in every aspect and made without compromises. The highly accurate and coherent sound fills up your room with massive headroom and dynamic range. The unrivaled listening experience is sure to impress even the most critical users.

On the back panel of K700 Pro, there is one switch for controlling the vertical directivity of the sound dispersion. The Wide option is recommended when the speaker is used for home theater, and the room has multiple rows of seats with height differences. The Narrow option is designed for circumstances, e.g., professional recording studios, when the user wants to limit the sound reflections for more accurate sound.

K700 has four 27mm low vibration tweeters, one 27mm pro tube tweeter, two 5.25" high sensitivity midrange drivers, and one 5.25" inverted high sensitivity midrange drivers.

Matrix Driver Configuration

Ken Kreisel Speakers are widely used in many recording studios and require high fidelity sound with low distortions. Ken Kreisel adopts the matrix driver design to reproduce the sound faithfully, also known as the line-array placement. By placing multiple drivers in a calculated parallel manner, the drivers constructively interfere with each other and produce a more evenly distributed sound wave. The workload of each driver is reduced, and overall output is increased. The results are lower distortions and perfect rendering of micro-detail, timbre, tonal subtleties, timing and precision. It also allows a broader listening area and lesser space reflections and makes the sound stage more realistic with a three-dimensional sound with the authoritative weight and emotional impacts.

Signature Pro Tube Tweeter

Ken Kreisel uses one tube tweeter and multiple standard tweeters to form the matrix. They all fitted with the signature waveguide for well-controlled dispersion and a smooth response on-axis and off-axis. The tube tweeter is responsible for reproducing a more extended medium-high frequency and achieving the low crossover point for a more vivid and cohesive sound. Other standard tweeters without rear chambers are responsible for the maximum extension of higher frequencies. The tube tweeter transmits the back wave into a rear tube chamber that loads and absorbs the sound. It prevents the tweeter from having internal reflections that cause wave cancellations and timing errors. The legendary Bowers & Wilkins Nautilus and Vivid Audio Giya share the same design, while Ken Kreisel used this design even earlier.

Exclusive Low Distortion Midrange Driver

The custom-designed Ken Kreisel midrange driver uses low-carbon T-shape magnets and symmetric magnetic circuits on the midrange drivers to support high excursion while maintaining low distortions. The diaphragm made of long paper fibers with a special coating is lightweight and robust, and the cone geometry provides a substantial reduction of traveling waves. The result is significant control of unwanted edge resonances in the driver. The overall driver design ensures increased power handling and enhanced linearity even at large amplitude, providing lightning fast, accurate, and effortless sound reproduction across the entire midrange.

Phase Focused Crossover

The crossover design of Ken Kreisel considers not only optimum frequency response but also timing and phase. With careful acoustic analysis of psychoacoustics and computer simulations on phase shifts, Ken Kreisel achieves nearly perfect frequency response alignment horizontally and vertically. The result is an outstanding three-dimensional sound with a well-focused image and smooth response over a wide listening area.

All Ken Kreisel Subwoofers and Satellites are sealed design. While most speakers nowadays adopt the vented(bass-reflex) design to squeeze more bass out but at the same time makes the sound muddier and sloppier, KK speakers insist on using the sealed design to deliver the more accurate, punchier, and tighter sound. Sealed design enables you to experience the clean and authoritative deep bass and ultra-fast transient response. Unlike the vented design, which may play fairly loud but boomy, Ken Kreisel speakers are well controlled. The more precise sound, superior definition, textures and faithful music reproduction are why Ken Kreisel speakers are loved by many professional musicians, audio engineers, and sound enthusiasts. A complete Ken Kreisel system requires the satellite speakers and the subwoofers to both participate in sound reproduction. The system can minimize weak bass, incorrect phase, and baffle diffraction distortions often found in conventional full-range systems. Every listening room is different and has a significant influence on sound quality. With the Ken Kreisel satellite/subwoofer system, you can easily locate the satellites at the best place for imaging and the subwoofers at the best position for strong bass. The high flexibility and the smooth integration of Ken Kreisel subwoofers and satellites enable one to achieve the best possible sound in any room, resulting in an open, natural three-dimensional sound.
