Loudspeaker design using VituixCAD
These loudspeaker designs are based on transducer datasheets. The Sound Pressure Level (SPL) and impedance curves of the transducers—mounted in the enclosure and placed in a 4π full-space environment—are generated using the VituixCAD Enclosure and Diffraction tools.
Loudspeaker systems: Closed Box, Basreflex and Passive Radiator. Additional systems available upon request.
Crossover filter options: Linkwitz-Riley (LR2, LR4) and Butterworth (B1, B3). Additional filter types such as Elliptical, Duelund, and higher order filters available upon request.
Digital active or analog passive filter.
Customer input: preferred loudspeaker system, selected transducer types, desired crossover filter type and cabinet dimensions.
If assistance is needed in making these selections, we can provide some expert guidance.

Loudspeaker design using Leap
The designs in Leap allow advanced 3D enclosure modeling in a free-space domain, accompanied by a comprehensive 4π analysis to simulate power and directivity index responses.
There are two design options.
Option 1: Design based on Transducer Datasheets
Transducers models are created in Leap using the TSP, SPL and impedance responses of the datasheet.
3D Modeling: a cabinet model is created in a 3D environment.
Feasibility Assessment: design evaluation against target specifications, including sound pressure level, cabinet diffraction behavior, sensitivity, frequency response, impedance, room power, directivity index, maximum sound pressure level, and power handling.
Refinement: The initial concept can be further refined and validated through targeted acoustic and electrical measurements.
Option 2: Design Based on Acoustical and Electrical Measurements
Measurement-Driven Approach: acoustical and electrical measurements are used to generate the required sound pressure level and impedance curves. If needed, transducer models are developed to fine-tune acoustical measurements, especially in the low-frequency range.
Extended Analysis: off-axis measurements can be used to calculate the full space power and directivity index response curves.
Pricing: available on demand
