- I have three questions:
-
- 1. I have a lot of RG-58C (50 ohms) and was thinking of using it to
- connect my Marantz 200W amp to a pair of Klipsh Heresy speakers.
- Are my calculations showing that nearly 86% of the signal would be
- reflected back from the 8 ohm load? So, not only "no" but "hell no"
- I shouldn't use coax to drive my speakers?
- However, my instinctive feelings tell me that at because the line
- is not infinite (transmission line theory), the connection is
- analyzed as a RC circuit showing the characteristic impedence of the
- line is close to the load value so reflection isn't a problem. Also,
- at 30pF a foot, an audio signal would hardly notice. In fact, it
- seems connections using coax would be better than a zipcord (~150
- ohms) or even a twisted pair and much less noisy than both?
-
- 1a. Side Ques: I heard that the "Heresy" name came about because its
- design (Conventional paper cone) is not the standard (does not
- follow the Klipsh design doctrine). Any truth to this?
-
- 2. Is there a FAQ list on VCR problems? It seems that everyday there
- is at least one question about VCRs... speaking of which... I have
- a RCA that stops a couple seconds after pushing play no matter where
- you are on the tape.
-
- 3. I have a couple of coax splitters that I acquired in college from
- my cable connection. I would like to use them to split an antenna
- signal (one to TV one to FM stereo). Is there any truth to the
- rumor that the splitters filter out high UHF? I.E. I won't get
- channel 68 (~795MHz) through it.
-
- Thank you for any comments.
