Klipsch Cornwall Sound Question

[wdecho]

So 4 ohms is really the way to go then, right?

There is not really a right or wrong way, just what sounds best to you. I am assuming you are talking about a tube amp. For all intense in purposes the speakers are supposed to be hooked up to a SS 8 ohm connectors but with tubes and OPT's it could work best either way. Even with SS I see no problem having it hooked up to the 4 ohm connections.

"So are you saying that you can get better sound on the 4 ohm tap with Klipsch speakers and tube amps?"

At low volumes a speaker always plays loudest on the 8 and 16 ohm taps. As you turn up the volume and 'thump' it a bit you will find the speaker sounds the best on the tap that closest matches its impedance, and plays the loudest too.

Always try the 4 ohm tap. Leave it on whatever sounds the best.

Hint: it sounds 'thin' when you turn it up if you have it hooked to too high of a tap.

Easiest way to check LF driver phase is to stick a 1.5V battery across the terminals and see which way the cones move. Simple and infallable.

Hello,

I just purchased a pair of Cornwalls with the B3 crossover, 1983 I believe.

I am having some problems with the bass sound. Its there and its clean, but it just doesn't seem to be in balance with the levels of the high end. I want to keep turning up the sound to bring the bass out, but obviously that turns up everything (the bass preamp adjustment also doesn't fit my tastes). Maybe I am just not used to such high end speakers, but in a way my chest kind of feels empty when listing because i want some more low end to balance with the high end. So I was wondering if this was typical of the Cornwalls...

Pictures of the crossover please.
Investigate if the components (4mH coil) is the original.

I am not sure about the Cornwalls but my LaScala's are 4 ohm woofers, 16 ohm mids, and 8 ohm tweets but the overall specs are called 8 ohm. And actually that is not the exact impedance of the drivers and as most know the impedance changes with the frequency. There would nothing wrong using the 4 ohm tap on your amp if that is what you like best.

Klipsch used four-ohm woofers in their bass horns because they claimed that horn loading increased the impedance. Since the Cornwall has ported bass, I expect they used an eight-ohm woofer.

The Cornwall uses the same woofer as the La Scala and the Khorn.

Look again at the impedance curve: http://www.diyaudio.com/forums/multi-way/283445-klipsch-cornwall-sound-question-2.html#post4542632

I don't know why this is an issue for this thread's topic. Here is an impedance plot of the Khorn done by Richard Heyser--showing the impedance rises in the bass bin below 400 Hz.
