Hill Speaker Systems Design Philosophy

Since the early 1970s, Hill design philosophy has been the ‘Faithful Reproduction of the
Original sound’. Throughout the '80s and '90s Hill Speaker Sytems established their
reputation with many international touring artists, in theatres, arenas and stadiums
around the world - from Wembley Stadium to Madison Square Gardens to Nuremberg. In
the mid-'90s, under the banner 'faith comes through hearing', Malcolm Hill designed the
PowerCube, a compact self-powered speaker that reproduced the spoken word with
excellence, whilst maintaining performance for live music, which has become so much a
part of the contemporary church.

Flawlessly effective with any source:
- piano and other classical instruments
- speech
- live rock band
- film soundtrack

Unequalled articulation of the human voice.

The most generous dynamic range of any speaker in its class.

This level of performance has been achieved through extensive development of high-power studio-proven drive units, rather than conventional PA drivers.

The unique ring radiator, coaxial drive unit, used throughout the M-Series.

Design Principles

Frequency response

The ability of a system to respond to all frequencies equally; This parameter is not as
critical as generally believed; it is primarily a venue acoustics issue.

Hill Systems: 30Hz - 18kHz

Power response

The ability of a system to deliver full SPL at any frequency; This parameter is invariably
overlooked, but is crucial to effective live sound, particularly when vocals are a priority
in 'the mix'.

Hill Systems: 35Hz - 16kHz

Transient response

The ability of a system to reproduce transient signals in relation to their steady state
equivalent. E.g. the punch of a kick-drum, the snap of a snare drum; the zing of a
cymbal; the attack of a piano.

Hill Systems: 10% - 90% dV/dT

Real-world Application

Soundwaves naturally tend to propagate spherically, and can, in a simplified
demonstration, be compared to the wave propagation when dropping a stone into a
pond.

M-Series are designed to work with this phenomenum, whether as single units, or as
effi ciently coupled multiples. Utilising Coaxial drive units, a Virtual Point Source,
Coherent Wavefront is developed immediately at the front of the Array, providing
consistent sound balance from the front of the venue to the back.

M-Series can be configured as Arc Cluster, Matrix Array or Line Array to suit the venue
sound design.

Seamless midrange

Conventional systems are multiway, with one or more crossover points at frequencies
where the human ear is most sensitive to anomalies (100Hz -3kHz). M-Series are 3 way,
with a 5 octave, seamless midrange bandwidth.

This seamless midrange, together with full midrange SPL Power Response, equips M-Series to deliver stunning vocals throughout the venue.

Amplification

Conventional systems use amplifiers primarily designed for power and reliability, rather
than sonic excellence. In addition, systems including subwoofer boxes using remote amplifiers suffer significant
loss of power and drive-unit control through the speaker cable. M-Series go further,
using high-headroom studio monitor amplifiers, installed inside the speaker, eliminating
all power, control and damping losses.
