Just read this bit from this website http://www.sge-inc.com/expert.htm. The
writer states that a 10-foot distance difference in speaker wiring will make a sound quality difference, but then suggests that the extra unused length on one side be coiled up. Wouldn't this act like an inductor limiting higher frequencies and causing the user a new headache? :-) Or now that the wire is coiled up on itself, he might get phase-shift interference, from the later waveform in the top of the coil interacting with the earlier waveform in the bottom of the coil. Just wonderin' what you all think of this guy's advice. By my calculations, assuming the speed of electricity to be only *one tenth* that of light to be conservative, this 10 foot difference would represent a 1 microsecond delay to one speaker. Not 1 millisecond, 1 _micro_second. HA! -Bill -------------------Begin Excerpt------------------- Mr. Expert, I have a really good receiver and decent speakers, but they sound terrible! I have heard that the shape of the room has a lot to do with the way a stereo sounds. The highs are real nice and clear, but the bass seems muddy and lacks definition. I have checked the phasing of the speakers (red is connected to red and black to black on both of them) and that is OK. What is wrong?" -- name withheld After a couple of e-mails back and forth, our correspondent informed me that he is in a very long, thin room (30 feet by 10 feet). He has the speakers along one of the 10 foot walls. His major listening area is about 10 feet from the speakers (good placement, an equilateral triangle). His receiver is on one of the side walls so that one speaker is 12 feet from the near speaker and 22 feet from the far speaker. Now comes the big question -- how many feet and what kind (gauge) of speaker wire do you have going to each speaker? This is where his problem lies. He had about 15 feet going to the near speaker and 25 to the far. In a stereo installation, the speaker wires must be the same length to each speaker. The bass signal is usually mixed equally in each speaker and the difference in length of wire could cause a small phase differential between the woofers! I advised him to get a new 25 foot long piece of the same wire he was using (a good 16 gauge high quality speaker wire) and to use it to connect the near speaker, coiling up the excess in a place where it was not too unsightly. He called me on the phone to thank me. The improvement was so dramatic (in his case) that he went out and bought 10 new CDs! --------------------End Excerpt-------------------- |
