Hello,
i wanna share with you quite a strange story
i bought the Presonus Eris E8 quite a while ago (like in 2016) and was blown away by the piercing high frequencys (and the otherwise really good sound), well the -2 to -4db highshelf eq helps that get spoken about quite alot on the web for the Eris but it kept me curious how sound engineers can bear the sound while working since they are studio monitors and they should be used "flat" for that purpose
i even send them back to thomann who measured them, all ok but i kept going and send them back to Presonus directly and got a new pair since i thought they are defective in some way (well ... my first "good" speakers and no clue about audio at that time)
well, since then i lived with the EQ setting on the back of the speakers for -2 to -4db high frequency reduction and since i use CamillaDSP in moode i Eq`d it there
fast forward, since a few months i noticed that
A. my left speaker/tweeter isnt happy with some frequencys, in layman terms it sounds like it "breaks up" or clips or something even if i just listen at about 75-80db still unsure what it is but for most music it sounds fine, sinus sweeps sound perfectly fine too! (please let me know if you have a clue)
B. the right speaker isnt happy with some low frequencys, i think its the resonance frequency of the speaker itself, something rattles inside if the right frequency gets hit
now i found recently a good song that hits the right frequency with each bass and thought "lets look inside" maybe something loosed up or something, everything was fine so i thought maybe its the cables to the speakers that rattle against something, so i took some cable ties and remanaged the cablemanagement inside and where the tweeter and woofer cable where tied together in the first place, i actually seperated them, i listened and HUH the high frequencys sound much better now.... so i also did this mod for the left speaker and yea, improvement overall in the high frequencys, i was even able to turn the EQ off, well i ended up just reducing the high frequency reduction to around -1.5db where it was before -2.5
Now im questioning myself a bit, is it even possible that the high frequencys sound worse if the cable of the woofer touches the tweeter cables? is it some kind of "overspoken" signal? and if yes why the hell the manufactor decides to tie them together?
Curious what you guys think! and maybe you can help me with the tweeter problem in the left speaker that sometimes i think also apear in the right speaker but by far not as worse, is it maybe just what we call in german "Klirrfaktor" ?

If this is the wiring after the amplifiers it doesn't seem likely they would do this into the low impedance of the speakers.
yup its the wiring of the integrated amplifier to the tweeter/woofer with normal copper wire
well they did! they were new when i got them. So this is a common problem? or atleast a problem people are aware of?
The only thing I can think of is if the woofer and tweeter amps are self oscillating class d there could be odd behaviour.
if i remember right its class AB, well im really happy i found this out in the end, its kinda subtil but if you heared the speakers for 5 years before you just notice that the high frequencys sound "smoother/more pure" (well atleast thats the shortest discription i can give) with the cables seperated, i also think the audio from the woofer sounds a bit better but its much more noticable in the high frequencys
