Hi audiomaniacs,
as mentioned in my intro, this thread is about long-lasting back-brain audio-project.
It surrounds the topic "Current-Drive for Loudspeaker (I-Drive vs. V-Drive).
I intend to simulate characteristic params like THD, IMD, Step-Response, Bursts, etc. using tools like Matlab and Spice.
All this with modelled real loudspeaker loads.
Linear loudspeaker models are available and already producing reasonable results.
Currently I am working on analysing scripts and algorithms.
The benchmark shall include <10 linear amplifiers, represented by available schematics in gEda, KiCad or Eagle, to support netlist creation for Spice-simulations.
My current portfolio are from Elektor (Crescendo, Kleine Qualitaetsendstufe, Hexfet) and Rieder Ampino.
The simulations will be restricted to the linear travel of the loudspeaker-cone. Extended nonlinear simulation can start later.
My startup questions:
1. As I don't want to re-invent the wheel: are there already any contribution along this topic within or outside this forum or is this a entirely new question?
2. What would be your proposal for amps to be included as candidates for benchmarking (Pls. note: I need their schematics & BOM to take part)
3. What is your recommendation for metrics to be analysed in addition to m.a. characteristics?
looking forward to your feedback
