Loudspeaker Design
Complete on demand loudspeaker designs. The loudspeaker system, the X-over type and an analog or digital X-over implementation can be chosen.
| SYSTEM | X-OVER TYPE | X-OVER IMPLEMENTATION | |
| – closed box – vented box – passive radiator – transmission line – dipole | – Linkwitz – Riley – Butterworth – Elliptical – Duelund | – Analog Passive with coils, capacitors and resistors – Analog Active using opamps – Analog Active using tubes – Digital Active on several platforms like miniDSP, Hypex,… |
Design flow:
- The speaker will be completely simulated using the datasheets. Transducer models are made and placed in a cabinet model in a virtual full space environment. Sound pressure level and impedance curves of the individual transducers in the cabinet will be simulated.
- Using the SPL and impedance data curves, the X-over filter is designed. X-over targets are created conform the chosen X-over type.
- Active crossover filters are designed using analog functional blocks at first. For analog active filters these functional blocks are transformed to operational amplifier blocks. For digital active filters the blocks are transformed to digital biquads.
- Complete power and directivity study and X-over filter design using acoustical measurements on demand.
