Horns with multiple drivers and arrays of multiple loudspeakers can be modelled. The driver diaphragm is assumed to be a rigid plane piston. Horn segment parameter values can be reset to zero by entering a blank for the throat area, mouth area, axial length, flare cutoff frequency, flare parameter or throat entry half-angle. For multiple-segment horns, the more that the value of Cir mouth circumference in flare cutoff frequency wavelengths exceeds 1 for any horn segment, the less accurate the calculated throat acoustical impedance and other results become. After calculating results by pressing F5 or Calculate, press F2 to move to the next window, Shift+F2 to move to the previous window or Esc to return to the input parameters window from any result window. Notes 6 to 14 on pages 18 to 20 explain how to model a mass-loaded horn, an offset driver horn, a tapped horn, a compound horn, a back-loaded horn, a horn-loaded vented-box enclosure or a direct radiator in a vented-box enclosure, closed-box enclosure or infinite baffle.

The design is assumed to be axisymmetric. Use the mouse pointer to identify component parts and show scale. Acoustical Impedance Horn throat acoustical resistance and reactance in normalised acoustical ohms versus frequency in hertz. The actual acoustical resistance and reactance can be determined by multiplying the chart values by the given scaling factor. SPL Response Sound pressure produced at a point source normalised distance of one metre when the driver is supplied with a signal of a given voltage, versus frequency in hertz. The level is expressed in decibels relative to the standard reference sound pressure of 20 micropascals. The default response assumes constant directivity. The Directivity Response tool can be used to take into account the frequency dependent directional characteristics of finite single-segment horns. Electrical Impedance Loudspeaker electrical input impedance magnitude in ohms versus frequency in hertz. The actual displacement can be determined by dividing the chart value by the scaling factor, where given. Behaviour at all input voltage levels is assumed to be linear. No allowance is made for low frequency high power amplitude compression. Each diaphragm in a multiple driver configuration has the same displacement, as given by the calculated value. Phase Response Phase-angle difference in degrees between voltage Eg and the output sound pressure of a loudspeaker system, versus frequency in hertz. By default, the phase is corrected by adding a linear phase offset equivalent to the mean group delay across the -12dB delimited SPL bandwidth. Use the Delay tool to specify a different value. Group Delay Negative derivative in milliseconds of the loudspeaker system phase response, versus frequency in hertz. Group delay is a measure of the rate of change of phase with respect to frequency, and is positive when the phase slope is negative.

The direct radiator cannot be located inside the horn mouth. For a finite horn-loaded vented-box loudspeaker system, combines the port output with the default displayed horn SPL response. The port outlet cannot be located inside the horn mouth. For a direct radiator vented-box loudspeaker system, combines the port output with the default displayed direct radiator SPL response. The path length from the rear side of the driver diaphragm to the port outlet is assumed to be equal to Lrc plus Lpt, as shown in the schematic diagram. The distance from the port outlet to the listener can be adjusted if necessary using the path length difference parameter. A positive value for path length difference increases the listener distance. Destructive interference nulls are often not as deep as predicted, due to the directional characteristics of the front and rear radiated sound. Multiple Speakers Displays the normalised far-field SPL response of a given multiple loudspeaker array connected to a single amplifier. Not applicable to infinite horns. Click on the chart to show the efficiency value at a specified frequency. Sound Pressure Displays peak sound pressure in pascals versus frequency in hertz. Click on the chart to show the sound pressure value at a specified frequency. Particle Velocity Displays peak particle velocity in metres per second versus frequency in hertz. Click on the chart to show the particle velocity value at a specified frequency. Range When selected from the electrical impedance chart window, sets the electrical impedance chart range. Select Zoom to optimise the scale for the resonance peak. When selected from the group delay chart window, sets the group delay chart range. Delay Sets the phase response chart offset delay correction. Select zero delay to show standard wrapped phase. Isophase wavefronts are shown. Options Sets the throat chamber and rear chamber resonance masking and default result window options. The application assumes that the velocity of sound in air is 344 metres per second, and that the density of air is 1. The driver diaphragm is modelled as a rigid plane circular piston. No allowance is made for frequency-dependent directional characteristics due to driver cone angle or cone material, or for changes in moving mass, acoustical impedance or radiated power caused by diaphragm resonance modes. Also, horn flare directional characteristics are not taken into account when calculating the constant directivity SPL response. This means that the actual upper frequency rolloff for a cone type drive unit coupled to a straight-axis horn can in some cases be more than one octave higher than the predicted value. The constant directivity SPL response is also the acoustical power response. No provision is made for horn transmission losses. The rear chamber volume is the effective enclosed air volume behind the driver diaphragm, including any space occupied by acoustical lining material but excluding port tube, driver magnet and chassis assemblies. The throat chamber volume is the effective air volume between the driver diaphragm and the throat chamber port, the throat adaptor entry or the horn throat. The locations of the throat chamber and rear chamber are as shown in the schematic diagram. The driver entry point is at S2. Vtc and Atc can be used to specify a chamber between the diaphragm and the throat entry point. Ap1 and Lpt can be used to specify a port opening between the chamber and the horn not required if the cross- sectional area of the opening is equal to Atc. By default, with no rear chamber specified only the horn output is calculated. The Combined Response tool can be used to determine the rear output or the overall front plus rear SPL response. TH can be double- clicked to set the optional TH1 flag. Driver entry points are at S2 and S3 for a three segment TH horn, S2 and S4 for a four segment TH horn, and S2 and S3 for a four segment TH1 horn. Vtc and Atc can be used to specify a chamber between the diaphragm and the throat entry point. Ap1 and Lpt can be used to specify a port opening between the chamber and the horn not required if the cross-sectional area of the opening is equal to Atc. The Loudspeaker Wizard tool can be used to change the driver position without altering the horn length or flare. To model a compound horn select the compound horn option from the Driver Arrangement tool or double-click Nd, OD or TH in edit mode to set the CH flag. Horn 1 is specified using segment 1 plus segments 2 and 3 if required. Horn 2 is specified using segment 4. By default, only the horn 1 output is calculated. The Combined Response tool can be used to determine the horn 2 output or the overall horn 1 plus horn 2 SPL response. By default, only the horn output is calculated. The Combined Response tool can be used to determine the direct radiator output or the overall horn plus direct radiator SPL response. To model a horn-loaded vented-box enclosure select the 'Rear Vented' option from the Chamber tool. By default, only the horn output is calculated. The Combined Response tool can be used to determine the port output or the overall horn plus port output SPL response. By default, only the direct radiator output is calculated. The Combined Response tool can be used to determine the port output or the overall direct radiator plus port output SPL response. The 2007 flare profile used in the Le Cleac'h horn simulation model becomes slightly inaccurate near the horn mouth. The error is not large enough to make any practical difference to predicted results. For construction purposes the exact axisymmetric profile can be exported by selecting the appropriate option when prompted.
