Design Philosophy

Hill Sound Systems

Since the early 1970s, Hill design philosophy has been the ‘Faithful Reproduction of the Original sound’.  Throughout the '80s and '90s Hill Sound 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.

Coaxial Ring Radiator M-Series Drive Unit

From it's heritage (M2 Gary Numan, M3 Saxon, M4 Live Aid, AC/DC, Monsters of Rock M6 AHA, Status Quo, "Rock till you drop", Frankie goes to hollywood, B52s) the M-series has now been reimagined for the 21st century. 

  Flawlessly effective with any source:
   -  classical instruments, including piano
   -  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.

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 efficiently 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 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.
