As some, or most of you know, I'm a scientist by profession. As JA also has an engineering background, I thought I would post my experiences with using Design of Experiments as a way to assess integration of subwoofers into a "mains" system.

Odd Speaker Question

The Entry Level
Submitted by JIMV on

I have a friend who has a rather expensive set of speakers. He bought them used and the shipper dropped them on delivery. That was a while ago. The problem is, there does not appear to be any significant midrange in either speaker. The treble is good as is the base. It is almost like there is no midrange at all....changing amps has no effect nor does moving the speakers...

So, my question...what can kill the midrange on two speakers? Do makers use multiple fuses so that one failure would not shut down the entire speaker??

In sixth grade, I was given a Victorinox Swiss Army knife. I loved it. An avid camper and erstwhile Boy Scout, I was amazed at how many things I could do with this well-made, pocket-size wonder. I used its tweezers to remove splinters and ticks, its scissors to cut thread, its can opener to prize open tins of baked beans, and its knife blade to whittle, occasionally cut myself, and generally wreak teenage mayhem.

As I grew older, I discovered that using specialized tools for a given job was generally easier, faster, and more pleasurable than using my Swiss Army knife's utilities. Though I could cut a tent's ground cloth with my knife's scissors, a plain-Jane pair of Fiskars worked much better, an OXO can opener got me into those baked beans much faster than my Victorinox could, and even my Swiss Army knife blade didn't stay as sharp or fit in my hand as well as a simple Buck knife. Still, there was no doubt that my Swiss Army knife was a great tool and a good value, even if it was never the best tool for a specific task. To put it another way: The value of my Swiss Army knife was broad but shallow, while the value of something like my OXO can opener was narrow but deep.
