DizRotus Posted April 7, 2007 Share Posted April 7, 2007 I wouldn't, even if I had two set of Bob Crites' coat hangers. Quote Link to comment Share on other sites More sharing options...
pauln Posted April 8, 2007 Share Posted April 8, 2007 I think some beleive that since the independent crossover parts are separating the drivers (although all connected to the same amp outputs as parallel circuits) that there might be a difference in how the drivers and amp interact... for example back emf from the driver to the amp is different for the different drivers (although all the driver paths to the amp are parallel and therefore connected)... some actually use different cables to facilitate any difference (big fat ones for the low end and smaller ones for the high end). In a way, it sort of makes a little logical sense if one is thinking of electricity in terms of hydrodynamics (plumbing), but the speed involved with the electrical signals is so many orders of magnitude greater biwire is generally considered an ineffective tweak - any back emf (or anything else) will get to all the drivers through the common connection to the amp, albeit delayed a tiny bit, but the speed and distance make the delay so small it is not thought to have any effect. Which is interesting in light of how shorter feedback loops in amp topologies (where the delay is really short!) are thought to have a positive effect over longer feedback loop topologies. It seems that for every tweak that is seemingly baseless in theory, there is a logically corresponding accepted engineering principal based on the same theory, so who knows... more incomprehensible things have happened and yet the world goes on...

Guest " " Posted April 8, 2007 Share Posted April 8, 2007 There are numerous reasons indicated on the attached PDF. Sorry for bursting the bubble.....watch that landing. The only way to accomplish what is indicated in the attached PDF is to the bi-wire terminals on your speakers.

jdm56 Posted April 8, 2007 Share Posted April 8, 2007 Another advantage of bi-wiring is simply that doubling the wire gives you the advantages of a single run of heavier gauge wire --lower impedence. Quote Link to comment Share on other sites More sharing options...

jdm56 Posted April 9, 2007 Share Posted April 9, 2007 "Every foot of speaker wire adds a bit more resistance, capacitance and inductance to the performance equation. While these parameters by themselves have minor sonic effects, the total impedance of the wiring network has a larger effect - especially on the amplifier. The trick is to minimize the effects of the wiring, so here's a good rule of thumb: For less than 50 feet to the speakers or volume control, 16AWG is fine From 50 feet to 100 feet use 14AWG For 100 feet or more use 12AWG Don't forget to account for the expected bass response and volume at which the speakers will be played. For primary sound where dynamic range is at a premium and full range sound is desired, use more copper. For background sound you can drop copper. In other words, you are unlikely to compromise the performance of a pair of 5-inch coaxial in-ceiling speakers placed in the master bathroom by using 16AWG, even if the run is 100 feet. On the other hand you may want to use 12AWG if you're wiring your main theater speakers - even if the run is only 30 feet." --Joseph D.

colterphoto1 Posted April 10, 2007 Share Posted April 10, 2007 yeah, that is a pretty stupid question BS, is that the best you could do? Quote Link to comment Share on other sites More sharing options...

ibanezhater Posted April 10, 2007 Share Posted April 10, 2007 I read on the Audio Critic's website where he said there was absolutely no need for bi-wiring. It kind of implies that the speaker cable companies just want you to buy more speaker cable. Quote Link to comment Share on other sites More sharing options...
