Biamping Biwiring my B&W 603 S3?

[franklin_boff]

Hi,

I have a set of 703 s3's and a Harmon / Kardon amp with 4 sets (2 pairs) of outputs... is there likely tobe any advantage in removing my speakers binding posts and using both sets of outputs?

Is this likely to damage my speakers? Will the crossover attached to the binding posts still filter out inappropriate frequencies if I do that?

And, I understand that this is biwiring. If I wanted to biamp, what sort of features would I be looking for in terms on an ampflier(s)? If there is a guide anyone could direct me to I'll happily read away.

All advice apprecciated...

Do you mean 603 s3's or 703's or what? Anyway, biwiring can do good with good wire but it is probably only worth it with 800 series. A nice rug on the floor will give you better return on investement than more cables

You are not removing the crossover so this is ok.

And, I understand that this is biwiring. If I wanted to biamp, what sort of features would I be looking for in terms on an ampflier(s)? If there is a guide anyone could direct me to I'll happily read away.

You will need a preamp and two stereo amps or one multichannel amp with at least 4 channels (most have at least 5). If you harmon has appropriate line level outputs, I think that you can just add one appropriate stereo amplifier. Again, this is probably just worth it with the 800 series.

So my advice is get your room acoustics right, and get good cables (for a total of 5-10% $$$ of your system) if you don't have some. But in the case of biwiring, I think that one great cable is better than two for the same price.

yes indeed i mean 603s not 703s

biamping

so, does this mean that in the world of hifi biamping, both amps feed the same signal into the speakers high & low terminals where the speakers built in crossover disposes of the signal it doesn't require?

the reason i ask is that in a pa system the signalis first feed into a crossover which separates the signal into bass & mid high or bass / mid / high and feeds only a particular frequency range into an amp and then on to th speakers...

cheers

It costs alot less to do a crossover for line level signals than for speakers. But in most HiFi cases, the crossovers are already in the speakers. A big exception would be *THE* B&W Nautilus that has an external cross-over and requires 4 amplification channels per speaker. Speaker companies just don't want to *force* you to biamp
