I think that you just baited DUP.
Lots of good questions with lots of various answers.
Wideband amps? Because they can and because having a really high frequency response creates an amplifier with a very fast response time.
Speaker response? Not as wide because of mechanical limitations.
Microphones? Don't know about them.
Movie sound tracks? Special effects and not accuracy.

Hook line and sinker............Actually there are mics that are way out there in freq response etc. JA uses them for tests I think. Earthworks. This being teh 21st century, things do improve. Extended freq responses, extremely FAST slew rates, super low distortions, high power, it all makes it all sound REAL!!! ALIVE, with SLAM IMPACT and teh complete dynamics of LIVE music!!! Using limited slow, poor, obsolete specs only limits teh realism of teh reproduce music.
One look at up to date 21st cnetury (well pionered in 20th century) HDTV image and the nearly 60 year old analog NTSC images, you will never want to look at non HDTV images. Same with reproduction of music. Once you get used to what these superior FAST, super extened freq responses in the equipment does to make it REAL. All else is crap.
Ribbon tweeters, super materials in drivers for great transients and stabilty, no breakup. It all matters. 8W 3% distortion tube amps just don't do it...maybe it did when 78 RPM records and Orson Wells was on radio, not today...unless you like the sound of the early days.
$100K TT or modern DSD recordings on even a $300 SACD player...I bet the DSD wins!!!
SACD sounds better with it's extened specs, that are in the straosphere, or a dynamically LIMITED analog 33 1/3 record, played with a stylus grinding off the plastic in each play. With $6500 cartridges, DSD SPECS smoke it all.
The Hyundai or the Porsche, both will do it's job, just one is doing it with so much more vitality, and IMPACT!!! Specs matter.

tru thanks. i actualy found someone who gave me an answer i was looking for. "the freqs we dont hear and that arnt put out by the speakers still effect the ones we do". But whats this thing with the amps being fast? Is there some latency issue or something? How does that work out?

Reactive devices in electronics like capacitors, create time/voltage delays. They can effectivly slow an amplifier down. A frequency response that goes well above the audible range is a good indication that an amplifier is not slow.
Yes, a pretty lacking explination.

so its kinda like how people judge video cards by memory size and not actual gpu clock speed. are there setups that arnt super wide band and still fast? what would the "specification" be called? or do you really have to just go by frequency responce to be able to tell?

Perhaps more important than how amps being fast works out (which has already been covered very well) is that you hear the difference immediately -even with aging ears like mine. My most recent amp upgrade was from a very musicical Musical Fidelity amp with FR rated 20-20K Hz to a Marantz rated from 5-100K Hz. Didn't take much of an audition to make the decision. It's like pulling off a veil.
