DESCRIPTION  

SPEAKER DESIGN  PACKAGE
A designed by Russell Storey from Stones Sound Studio using LEAP 5 Pro speaker  is a very comprehensive package which is developed from your or (our recommended) choice of speaker drivers wood materials high quality crossover components and low loss internal crossover cable.
We work closely with your feedback by phone or email  to develop a custom speaker system that will satisfy all your requirements.

SPEAKER DESIGN  REQUIREMENTS:

The Enclosure shape size, driver type, driver position, actually work in conjunction with the Crossover circuit design and physical component layout  ,type of internal cable and type of speaker cable plus Amplifier to create on large complex circuit which must be taken into account to design not just good but excellent high definition speakers. Many years of  experience in the high end speaker design industry assist in achieving a super dynamic  speaker system design  for any of your custom  applications be it  Digital Home Theatre Movies ,Home Theatre Music  ,SCAD Door Analogue record reproduction of sound .

ENCLOSURE DESIGN
The Enclosure (cabinet) shape size and your preferred room location and even type of music or Home theatre music and movie preferences are taken into account in the design of the speaker cabinet an application based on a quick sketch of your room shape and preferred seating position. The shape of the  enclosure (cabinet) front baffle edges normally either square ,round or chamfered are modelled  in Leap 5 Enclosure designer in conjunction with the physical position of the driver/drivers on the front baffle board . The optimum location for the drivers is computed in 3D space to give the minimum edge diffraction i.e. interference between the driver radiating source (the cone) and the cabinet edges.
At the same time the distance between each driver (driver to port, driver to tweeter, driver to midrange, driver to bass) is optimized to give the best frequency response with minimum distortion and group delay. Internal cabinet shape and its effect on the speaker driver and port are also incorporated into the design optimisation process By optimizing the intermodulation or (interference) between all of the acoustic sound sources  we can thus  minimise  the speaker enclosure system mechanical distortions. The result is tight clean dynamic bass mids and top end to die for

CROSSOVER DESIGN
 All of the  above Leap 5 Enclosure data  is then imported into the Leap 5 Crossover designer so that we are using the speaker driver + cabinet to develop the passive (or active) crossover circuit .The  individual speaker driver  X,Y,Z  (acoustic offset position) on the front baffle, LMS measured  impedance, frequency response, and thiel and small parameters (from our speaker data base or your speaker) are used to develop the optimum speaker system phase,impedance,and frequency characteristics giving  a very flat frequency and linear phase  response with minimum group delay across the 10hz to 40khz region.
Even real capacitor ,resistor and inductors measurements are imported into the crossover designer program so as to  take into account their effect on the electrical response of the crossover circuit and driver network  .(  most design  programs substitute synthetic components) thus giving loss errors in the final design. Using this crossover design technique  results in a fast transient response crossover network that is in sync with the speaker drivers achieving excellent low level detail dynamic range sound stage fast tight articulate bass mid and top end with extremely low distortion, minimum broad band phase error and group delay.

 LEAP 5 PRO- ENCLOSURE AND CROSSOVER -COMBINED SPEAKER SYSTEM DESIGN_
A Leap 5 Pro design will ensure your  combination of drivers crossover and enclosure  deliver not only good but excellent high definition sound quality from your custom speakers.   Home theatre Video  DVD Music or Analogue  Stereo will take on a new dimension where by your speakers will become the reference in your system .Usually your sound equipment outdates the speakers with time but at Stones we reverse this process making the speaker the reference so will actually hear any sound changes made by changing  your equipment in the future be it the interconnect cables,RCA plugs,Speaker Plugs Digital Home theatre receiver ,stereo valve amplifier,dvd,sacd cd with any type of program material.
