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.

I think the explanation of how and why these work is more than a little bogus.

Based on the values on the sample image it's more likely that these are acting as an impedance equalizer, lowering peaks that usually occur in the area between the mid and tweeters.  Not a bad idea really. 

In some cases though it may also just act as a tone control, lowering the output a db or so based on your amplifier's output impedance.

Yeah, they probably change the sound.  Is it removing high frequency "noise" or just removing high frequencies? That's another story. :)

Poor people often fool themselves into believing that the cheaper stuff is just as good


Great choice of words.
So eloquent a put down.

let’s try. When people first start in this endeavor they will buy lower tier equipment or what they can afford and convince them selves it is as good as the upper echelon audio equipment available.
You come off as an elitist snob. Not saying you are @artemus_5 just that post makes it appear that way.

Not totally true Erik, we used a spl meter to match output 
you are correct in untouched the spl is a 1-2 db difference 
but once mstched there was more depth and better stereo separation. The Synergistic model that had crapped out 
in that little tube our tech friend showed cheap no name resistor 
capacitor , and just picked a average ohm resistor Thst may or may not work with 8 or 4 ohm speakers , the Jupiter purifiers are built per speaker, my tech friend said this is far more sound technically He has over 30 years in as a tech he knows 
much more then most , and I think 8 am going to let him mod my speakers .

Artemis5 a very good choice of words , there are many people with $$ That are 
smart and buy tweaks,and areHumble, Unless you have owned any of these tweaks personally 
then you speak out of ignorance , just a comment without  basis .
