Probably an FAQ but I can't find it.
Is it worth it, or is it just snake oil?
My own belief is "snake oil", more akin to doubling the thickness of the wire used for connection.
Bi-amping though, is a different thing and may well be worthwhile
I have my fronts Biamped because I can, and I believe its worthwhile.
Well you could have said, it would have saved me a post
Hi all, I have just bi-amped my front wharfedale Modus 7 speakers, these speakers are 10 years old but never been used until now.
I think bi-amping has made a difference the sound quality seems to be better with the bass much richer.
I aslo could not find a clear answer but a local hifi boffin claims that bi-amping works best with the lower end speakers, as the more expensive speakers have greatly improved crossover units.
My advice is if you have the spare amp connections try it and judge for yourself.
The OP is asking about bi-wiring, not bi-amping.
It's easy to try bi-wiring for yourself and come to your own conclusion - use the speaker wire from one speaker to bi-wire the other and listen to just one speaker. Get acclimatised to listening to just one speaker first to make it a fair comparison.
You needn't spend much on speaker wire (no more than a few quid per metre for good quality, decent thickness OFC cable) so it's an inexpensive experiment to try in stereo too.
As someone has already said, it is just the cost of the extra wire to try Bi-Wiring. Plus it might be fun. Still, don't expect too much.
As far as Bi-Amping, most today have a 7-channel AV amp, but equally, most are only using it as a 5.1 surround system. That means you have two amp channels sitting around going to waste. You can usually put those spare amp channels to work bi-amping your front speakers, and likely is will improve the sound. How much it improves depends on the quality of your equipment. But what is it going to cost you? Just the price of the wire.
Just one thing, you have to make sure you tell your AV amp how you are using those extra channels. If you don't assign them to Bi-Amping, then it is likely to think they are surround channels, and therefore, running half your front speakers, they aren't going to sound right.
Bi-Wiring, try it, it's cheap enough. If you like it, then you like it, and if you don't then you don't. Live and learn. It is nothing but the cost of the wire. Still, just don't expect much.
I've found that bi-wiring does work if your speakers are design for it. My B&W's have the 4 posts but more importantly the crossovers are designed to be biwired.
As people say just try it but don't expect too much if the speaker crossover design is not suitable.
....and remember to remove the metal plate connecting the speaker terminals, so just two things....
IMHO, bi-wiring is snake oil. In a lab you may be able to 'see' a difference using lab equipment but to the human ear, having the same signal generated by the same amp plugged into different speaker terminals is identical to the same signal generated by the same amp plugged into bridged terminals - you're bridging the speaker wires at the amp end whether you like it or not!
But hey, if you got speaker cable laying about, why not try it. Or go really crazy and try different gauge wire for high and low frequencies.
The consensus is - don't bother. See this thread for the ultimate closure on bi-wiring.
