interconnects for frequency ranges
« on: 11 May 2005, 12:29 am »
does anyone know of any ic's designed to work in specific frequency ranges?   I've seen plenty of subwoofer interconnects for the low frequencies but I haven't come across anything optimized for the mids or highs.  i'd appreciate any input on this. thanks.

There is nothing special about the vast majority of subwoofer cables. They are generally the same design as the manufacturer's normal IC's, just longer and sold as singles, rather than pairs.

My understanding is the same as Dan's.  Some woofer cables include some extra doodads for connections.

As the manufacturers try to build IC cable that sounds excellent thruout the audio band, some cables may have, for instance, slightly cleaner treble than others, or slightly warmer midrange than others, but generally, they're all full-range cables.

Slightly off the subject, I believe strongly in NOT using ICs as tone controls or fixers for other system flaws.  Others disagree.

I make solid silver fancy interconnects that I can "Tweek" to phase better at the Frequency you are looking for.

$1500 per half meter.

jeff,
  i agree with you that ic's should not be used as tone controls however what if you are using the ic in a particular frequency range?  this happens to people who use active crossovers which is why i asked the question.  thanks for the input.

Bass ICs?

Whatever ICs you use, whether for bass or other, I would try to keep the cable capacitance to a minimum.

I'm not jeff and I didn't stay at a Holiday Inn Express last night, either. But I can say that an actual filter (aka, crossover) makes a far better frequency or tone control than any cable. If you did attempt to design a cable with a very narrow passband it should be matched to the filter/crossover it is going to be connected to, otherwise there are quite a few potential issues WRT phase, reflections and standing waves that come into play.

Dan, I believe vpolineni is looking for cables to use AFTER the crossover, cables that would be better suited to carrying narrower-than-full-range signals.  So...understading that...anyone have recommendations for, say, a 'treble' cable, or a 'bass' cable?

Dan, I heartily agree with Ben's statement in your signature.

What's the allusion to Holiday Inn Express?

It's a reference to their current TV ad campain.

I do understand that. My point is that I believe it is a bad idea, for the reasons I mentioned in my previous post. Also, while we think of 20-20,000 hertz as being a wide frequency range, the truth is that it's a very narrow range and tailoring cables with a passband of even 20-20,000 hertz is very difficult. Trying to make cables that only passes frequencies under 100 hertz is even more difficult and expensive. In fact, it's basically impossible, because what you wind up with isn't actually a cable at all. Instead it's a low pass filter that has a cable hard-wired into it.

Thanks, I think Ben was one of the wisest people to ever live. :)
