Hi guys.
 
Just wondering what anyone's thoughts are on the subject of Bi-wiring.
Specifically, we have just invested in a new home cinema set up and it is possible to bi-wire the front floor speakers.
 
I've read an interesting blog by Q Acoustics
 
https://www.qacoustics.co.uk/blog/2016/06/08/bi-wiring-speakers-exploration-benefits/
 
which suggests that the benefits are tangible and measurable.
 
But there is an equally well supported school of thought that this is nothing but snake oil and that manufacturers use it as a marketing ploy to get you Buy-wire.
 
I'm undecided, and have yet to buy speaker cable so if anyone has any thoughts, please let me know!!
 
Cheers
 

Snake oil. In my opinion.

"This means that you will end up using twice as much loudspeaker cable than if you used the traditional single wire method, which has prompted many cynics to coin the phrase “buy” wire to describe the process!"
 
Maybe the report was created by Monster Cable.

snake oil.

Never heard of this but if comes down to being able to try something new and a spool of cable and maybe some connector ends... if I had the money I'd give anything a go (that won't blow up my gear).
 
Ideally I'd have my own little cable making station (or at least the kit to set one up on the fly).
 
Yeah... some boxes of spooled audio/network cabling. Neat little bins with various connector ends and a set of tools/materials to hand build the buggers.
 
Cable prices are ridonculous and the quality is sh*te! Does not make for cost effective experimentation.

Okay... that's likely not helpful... but I made words and things!
 
 
 
yanno... werds and things?

Aren't most studio monitors bi wired. Only difference is both amps are in the same box.

Hang on that's bi amped.
What's bi wired?

The big question you have to ask yourself is if you two systems like this setup e.g. one normal and one bi wired and you did a very accurate A/B test I wonder how much difference you would actually hear.  And for a home cinema application I am not sure it is actually necessary. 
 
Separate amps being crossed over at line level and driving the speakers independently would sound better though for sure. I still would not do this for a home theatre setup though. Maybe a super Hi Fi situation or studio monitoring perhaps.
 
If you did go this route you can get 4 wire speaker cable of course. Have you got two sets of inputs to your speakers by the way? Or do you have to modify them.

 
 
I asked a similar question myself a while back Col, and got some interesting and enlightening replies.

Only if you assume the "tangible and measurable" benefits are not due to some combination of deliberate deception and/or incompetence on the writer's part. 
 
Reality is this: in a bi-wired (vs. bi-amped) configuration nothing is buffered, thus everything is always still in the circuit. You are either connecting things together at the speaker end or the amplifier end, but everything is still connected together. For any reasonable gauge of speaker cable there will be absolutely no difference due to cable resistance/capacitance/etc. and speaker cables simply do not produce passive inter-modulation distortion (PIM) in the real world. And if the cable was causing any effect at audible frequencies (and it doesn't with any reasonable gauge cable), it would still cause an identical effect it in a bi-wired configuration.
