Bi amp vs bi wire....difference?

[Deleted member 38504]

Can someone explain this in reasonable English please without too much technicalities? Specific to my Polk RTi A1 bookshelves.... will it make a difference is sound quality?

Thanks.

biwire= 1 amp, two pairs of leads one for HF and a for LF-per speaker.
Biamping= 2 amps four pairs wires ,connected separately to HF and LF of each speaker.
Does this make sense to you?

In English either of which won't help the likes of RTi A1.

In simplest English, it's exactly what the terms are.

Basic logic is to feed power to the tweeter(HF) and bass driver(LF) separately. Separation could be via two independent pairs of cable(4 WIRES) either coming from a single amp(bi wire) or from two different amps(bi amp).

Doing either will not make a difference to your Polk. If it's just for your understanding, Google it up, tons of articles and forums discussing it.

I hope you already have the definition.

To me, Bi-Wiring doesn't make much sense. But Bi-Amping makes some audible changes.
Again, this is purely subjective and varies from setup to setup as a whole.

Best way to find out is - try em' both in your setup and determine which suits you the most.

My mind.

The most difference is when the signals are separated at the preamplifier level using DSP or active filters then these signals go to separate amplifiers which directly feed the speaker drivers without the need of any passive crossover. These systems though costly have quite a few benifits acoustically. The b&w nautilus reference speaker uses such a topology.

Thank you !
it's a very nice pictorial presentation

By the way i own bi-Amp Genelec speakers IMHO, biamp sounds better :indifferent14:

Super thanks guys! Exactly what I needed to know! much appreciated!

I have my fronts bi-amped at the moment, albeit passively.

Has it made a difference ? My heart wants to tell me it does :lol:

I don't have experience with Polk's. I had my Usher V-601 speakers Bi-wired, and I did hear improvement in sound.

Bi wiring just separates the high and low frequencies at the speaker. You may or may not see a huge diff in quality. Another trick is to parch the high and low frequencies with a metal strip and connect the high frequency posts.

Bi amp actually amplifies the freq range of the speakers especially if they are inefficient ones. Most would see a difference in sound quality and levels

No, bi-wiring just passes the same signal through two sets of speaker cables. The separation is done at the speaker crossover network.

You may or may not see a huge diff in quality.

At best the jump in quality is very marginal. So marginal as to relegate this to the realm of psychoacoustics.

Another trick is to parch the high and low frequencies with a metal strip and connect the high frequency posts.

If you patch [which is what I assume you meant], the high and low binding posts - how is it a "trick" and what has that got to so with bi-wiring or bi-amping? What do you mean by "and connect the high frequency posts"

What? Care to rephrase that?

Knowing the thread opener, and him asking to explain in simplest of terms, I am sure all this information is going way way over his head, or maybe he has already given up and stopped reading this thread.

Sorry for being a bit off-topic.

I've been drooling over this type of non-scientific audio'foolish' ideas for quite some time now. No offense to the op.

I wonder that for these very reasons, cable companies survive and become rich. And I do believe some people hear 'difference' in ofc copper cables be it ic or a speaker cables. Obviously the placebo kicks in.

My mind.

Makes for interesting reading. But these are from cable manufacturers so...

Ah, I now understand where you are coming from by reading this on Page 4: http://www.audioquest.com/resource_tools/LearningMods/UndrstndgBiWr.pdf

It's best to not hear differences hyeah: for our own sanity.

I have owned bi wire speakers B&W LSA statements Axiom etc., which enabled biwiring. The little metal connectors between high low frequencies enabled single wired cables output as much as specific bi wired cables from MIT, Nordost, etc. so in my view, unless the speakers are internally bi wired there isn't much benefit. Open up a bi wired speaker and see for yourself.

And your point is .....apart from being a critic without much contribution to the discussion....
