Home Cable Asylum

Interconnects, speaker wire, power cords. Ask the Cable Guys.

Aside from the cable.. Is the actual system parts making the sound? or the wire?

Say my system has a particular fault. It this (imaginary case) say a speaker with a tendency to brightness.
Well at first the 'raw' wires sound good, but really they are masking the natural state of your tweeter sound.

Then a the wire becomes what it could be, you get back the too bright sound.
So it is a tough call.

With general issues in a system, it may be very hard to sort out what is causing what. One thing to note is if several wires do the same thing.. More likely the problem is not in a wire. And IMO one way to see if it is wire. Try bare wire. You would need to be exceptionally careful with bare wires. But for just a short jumper, you might be safe. With NO insulation at all, the wire will just be wire within a very short break in. See what happens.

IMO with bare wire on your jumper, and after a day the speakers are still bright, then IMO it is the system. Whether positioning, tilt, the basic speaker wrong for the room, a not so great amp.. Whatever.. it is not the wire fail. I would not hesitate to try bare wire for a three inch jumper. twelve inches? ahhh I would want to be ultra careful!

Also, you might try a resistor on the tweeter Using a 1 watt 1 ohm, or a 2ohm resistor as the jumper. it may do just what you need.

This is ONLY if the jumper is to a tweeter only. If the jumper is to both a midrange and tweeter, the resistor will be TOO SMALL And I would not suggest it at all in the case of a jumper between a woofer, and both midrange plus tweeter. Just too much power flow.
But if it IS only a tweeter. the one watt resistor should be fine. If you do try it. check how hot it gets playing music. If it only gets slightly warm. Good/normal. If it gets hot.. you need a larger wattage one. You can buy up to five watt one ohm or two ohm resistors. Use the smallest one which does not get very warm after a lot of play time..

A cheap resistor WILL hurt the sound slightly, But be less of an issue than too bright a tweeter. There are $25 a pop carbon resistors i They sound damn fine. A link to them.. (PS Dueland are 5 watts or 10 watts. Big watts does not hurt in this application and will work just as well as a one watt The critical number on a resistor would be the OHMS and for Dueland the 1.2 ohm is the one to get).

Added: On other possibility is the highs are not to loud, but too 'annoying'.
(I am a high frequency nut, they have to be perfect for me so I know of what I speak) Sometime if the highs are irritating, they 'seem' to be to loud... Which is just they annoy the hell out of you.. Thus they seem too loud. But in fact they may just be annoying. And if they stpped being harsh and ear killing, then the same level of sound would seem nice and normal. !!
Some things which came 'tame' annoying HF are power conditioners, or better digital components. If you use a only digital front end.. Perhaps it is giving you hash in the HF
The cheapest 'fix' for RF hash in the treble are ferrite plugs on the digital AC cord. And on the RCA exiting your digital player or DAC.
Cheap ones are about $5 each and the can snap on the wires.
