Bi Wireing

[Canada]

What in the world is it and what benfit does it provide the listener.

[nhaase]

Here's a little explanation I gave a few weeks ago: That's called bi-amping, and the idea of this is to send two different signals to dynamic speakers: hi- and low-frequency. Think of it as an attempt to be like component video inputs (where the color is split) vs. composite inputs. There are probably people on here who have more in-depth knowledge on this subject than I, but I tried it with one speaker bi-amped and another regularly wired and I could not perceive a difference. I have read up on this, just online, and numerous sources indicate that double-blind testing showed no difference.


Also, here is the thread where I made that post, as it gets discussed more:

....to start with you need 'biampable' speakers...ie) they would have two pairs of terminals.....one set for the bass driver & one set for mid/tweeter.....under normal operation they would have jumper plates joining the two sets of terminals. To biamp these speakers the jumper plates would be removed, now the high & low freq sections of speaker are separated & can be 'amped' separately. This requires more amp channels obviously and a processor/receiver/external-crossover that supports this as well.

One real world example would be, if you have large biampable front towers with good bass extension to lower freqs....they could be biamped, essentially creating two subs...& you could possibly ditch the standalone sub if you have one. I have fronts that are reasonably flat in freq response down to 25hz & they are biampable....i was thinking of going this route myself & dropping the standalone sub...in my case my sub has the same bass driver as my towers.

A woofer needs more power for a moment when it reproduces a loud sound. During this moment, some have speculated that the other speakers would be deprived of the signal needed for good sound. the theory is interesting but it also assumes you do not want to use the internal crossovers that came with your speaker. As the crossover is already directing the signal to the speaker(s) that can reproduce it best it really doesn't work like that. In the older tube amps, this may have been more workable due to the longer response time compared to transistors.

this thread gives me an idea...

does anyone feel like writing a little tutorial on speaker wire/configuration?? so I could make it a "sticky" in the home theater section?

you know, info on what kinds of speaker wire, connections,connectors, speaker types (sub,mid,tweets)...etc. Including pics and all...I think a good speaker tutorial could help others...PM me if you think you would like to get one going? appreciate it...sorry to hijack the thread...

but I think its been answered pretty well.

I think this is a "Sticky" subject though.... There are some things people find universally excepted, like larger speaker wire (gauge) for longer runs... I.E. use larger speaker wire for the surrounds, say 25 feet for each speaker needed (along walls, or in, etc.) and maybe only 7 or 8 feet for the fronts, so the rears NEED larger guage, and although you could use it for the fronts if you have it, it's not as crucial, because less is lost in the run, but when it comes to whether or not to bi-wire, or banana-plugs or clips, etc. there are camps for both sides. I don't bi-wire my fronts, center, or rears, although many think it's something I definitely should do..... Someone in an earlier post here said bi-wiring your mains would be a suitable substitute for a Subwoofer..... that can't be further from the truth, the Sub plays only the lower bass at the frequency you specify, (or range) and the purpose of bi-wiring is to increase the response in base and treble from the tweeter/sub because they're not competing for signal, but good cross-overs generally make this indetectable to the naked ear.

Biwire as commonly made is of no benefit. Better make like this:

Solid core cable. Can be bought very cheap. Not very flexible though.
For lowest inductance keep connect wires like described in:
http://www.jenving.se/pro.htm
If you have a jumper at the loudspeaker terminal (double-binding posts), keep it.

Some people wire the woofer with thick wires and the tweeter with thin wires in hopes to enhance the upper and lower ranges. However, sometimes that messes up the midrange, which is probably the biggest separating factor between the cheap 50 dollar speakers and the decent 300 dollar ones. So be careful. You dont want to mess up your midrange. Most instuments and the human voice all reside in the midrange. Without good midrange, you might not get the most out of your gear.

Besides, some hi-end speakers such as sonus faber do not offer biwire capabilies. So it may not be the best idea. Dont forget the extra cost of wiring.


As far as "how" to wire, the manual is your Friend!!!!!


This is what my wife wants to get me, but she just doesn't know it yet!

Speaker wiring, tutorial regarding wire gauges and the like are definitely a great sticky to consider, but details, may it be benificial or now, could post a wide array of opinions.

Just a thought.

My point exactly.... fact vs. opinion is a "Sticky" subject when it comes to Speaker wires, etc.
