- FWIW; your "series LCR" is usually referred to as a "Parallel LCR" oriented in series within the overall circuit .
- IME, a better choice LCR ( trap-filter) , would be a "Series LCR ( the components are connected in series with each other )"/ strapped in parallel across the load ( after the variable Lpad ) .
- The reason for this preference ? the "Series LCR" across the horn load, adds a nice bit of frequency dependant damping into the horn circuit / which I find is always necessary when using these drivers. The parallel LCR doesn't offer nearly the same level of added damping ( for some reason though I'm no E.E. so cannot really describe why ).
