Tweaks That plug in to speakers and ? Why they work

I have listened to the synergistic loudspeaker filters and fond a slight improvement 
then at our audio get together these much higher quality Loudspeaker filters 
made from Jupiter capacitors and Mundorfs  NewUltra resistors noticeably better in every way,
the ? Is how can something this simple work ? I was told you have to have the correct rated value of parts to be effective , they made a nice improvement especially in the top end .i found them on us audiomart but I see they just started to sell on here also , does the quality of parts really make 
Thst much a difference ?  I  am started to explore this modding trend  maybe quality does count 
more then I thought itshould.

My tech told me these purifiers are a filter which = cleaning 
high frequency hash or noise that absolutely rides about 12 khz typically ,and can be measured removing the noise does drop 1-2 db , but when taking a spl meter and matching output you can for sure hear better separation   and depth of image which effects the 
whole upper end , they do take time to runin , much better then the low quality build synergistic type.
