con su permiso, camoteque....link to baffle step correction....by Paul Joppa
http://www.t-linespeakers.org/tech/bafflestep/passive-BSC.htmlyou can ask your friendly cable maker to make one for you, it is very easy to make
and has been proven to reduce "shouting" in the audio nirvana FR speakers....
should you have further questions, feel free to ask....
since most pre-amps/buffers/sources will have source resistance in the
neighborhood of 1k and power amps' input impedance more than 50k in most cases...
just two resistors and 2 capacitors are all you need to implement this...
this are recommended values:
Rsource < 2k ohm
R1 = 10k
C1 = 1500pF
R2 = 12k
C2 = 0.033uF
Rload > 50k
Cload = 200pF
