I had a XO on my OB 3ways I was extremelly happy with, the simple XO circuit was together with test clips. starting from the end of my ZU Libtec speaker cables. I decided to hard wire it all together with some 24ga 4n silver solid core over cotton I had stashed & fired it up. Result is not good.. bright & or to detailed.. that might pass , but the biggy is my mid bass is gone from 150-300Hz.. 150hz down is handle from seperate amps.. speakers are B200 & G2 ribbon off a 300B PP amp.. it was perfect, it is not now. I will try & rewire with heavier ga wire this weekend,, such a bummer.. is it the light gauge.. I just can't believe it actually..something is WAY off..
Follow Ups:
false alarm on the silver..it turned out to be a week signal going to my plate bass driver amps, that handle everything from 150hz down in OB..I use a by-passed output stage NOS dac & have 2 sets of RCA outs, one set is low voltage by-passed mode, the other set is normal 2.0v + using the output stage & the op-amp..I forgot I hooked mu plates to the by-passed RCA's ..my plates don't like weak signal's..sorry for the confusion. all is very well....it was not 150-to 300 problem..it was 150 down problem....

maybe one of the bass/mid drivers on one side is wired out of phase? Classic symptom as you described.Cheers
I have used 28g wire for speaker connections and internal speaker connections for years.
I've had good results with 4 strands of 24awg in cotton as speaker cord.
I am leaning towards it not bieng heavy enough gauge as the test clips were much heavier ga.. It is more detailed & has the silver sonic si but..as stated the mid bass has ran to the hills. I will check for circuit error 1st, then up the ga to 14.. Circuit is single runs of only 1- 24 wire ga. I hope I can conquer this if not it is solid 14-18g ga copper in this set up I think, my amp might not like the light ga wire..I just won't know till I test..such a bummer cause I soldered everything, even to drivers, & was hesitant to do this, just in case,, well it bit me good..lesson learned.. I will terminate with normal quick disconnects.
Hi.I used #22 solid 4N Germany silver wires for my ICs. For speakers, #14 is the thinnest I would use.
Also, silver needs throughout break-in bigtime. Check up how I speedy break in my silver cords from my post yesterday below. I give the ICs or power cords minimum 120 hours non-stop high power breaking in before I ever start listen to it.
Silver wire is a better conductor of RF noise, so you might also have RF noise problems.
.
Just because of the metallurgy?
Clean copper and clean silver should behave similarly at any frequency we care about. However, real copper is corroded by exposure to polluted air, and real insulation is not impervious to this pollution. The corrosion products of copper are semiconductors, and I believe they would increase the effective impedance of the wire to RF.
two things. 24 gauge is small for a speaker IMO. There is a period of break in for new soldering and new wire IMO. I usually wait until I get 24 hours on fresh installed components before I do any critical listening.
Silver has a notoriously long break-in period. It does sound bright & thin at first.Let 'er rip for a week, without listening to it if you can, and then listen.
