- Re: Somebody's Radio Shack Speakers (the ones rated highly in Consumer
- Reports) are not working well as center-channel speakers.
-
- Radio Shack makes total garbage; most likely your problem is all Radio
- Shack's fault. I would never buy a Radio Shack product. Nearly all
- of their stuff is either discontinued, or junk from the far east that
- never sold on the home market. The one consistent thing about Radio
- Shack products is that there is no Quality: Radio Shack makes GM look
- like Toyota! In the case of their integrated circuits, they once sold
- factory rejects (cosmetic or otherwise) that were touted as
- top-quality stuff, just to increase profits. A friend once bought a
- walkman and it broke in 2 weeks. You get the idea. I have seen more
- broken Radio Shack equipment than working Radio Shack equipment in my
- lifetime.
-
- The bozos at Consumer Reports use weird science; no matter what they
- publish it is usually wrong. There are at least 6 reasons why
- Consumer reports publishes utter garbage:
- (1) There is no statistical evaluation to test if a
- manufacturer builds products of consistent quality. For instance, the
- time of year and/or production batch determines the quality of
- spaghetti sauce more than anything else. The idiots at CU never even
- dreamed this might be true.
- (2) They almost always have a major goof, i.e. forgetting to
- test if a speaker is directional, forgetting to test the quality of
- slow-motion effects on hifi VCR's, etc.
- (3) Whenever they test something you REALLY know a lot about,
- the results are appalling. Example: When they tested bicycles for the
- first time, they tested models in the $100 to $300 range. Guess what?
- With bikes you get what you pay for! They ended up ranking the
- bicycles according to price. The next time, they tested bikes with
- radically different wheels, and of course, rated the bikes with
- lighter wheels as superior. This is not a controlled experiment.
- (4) CU's ratings are about as subjective as subjective can be.
- Consider the original rating on the 1979 plymouth Horizon. CU decided
- to do a hatchet job on this car. To murder it, the report contained
- all sorts of crap, "We thing these control stalks on the steering
- column are a bad idea, every car should have pushbuttons on the
- dashboard." Five years later, same car: "We liked the control stalks
- on the steering column, and are glad that these controls have taken
- over the industry."
- (5) You'll notice that they never publish actual measured
- values. This allows them to get away with outright scientific fraud.
- If they published actual values (i.e. measured s/n, measured THD,
- etc.) rather than rating circles, then someone could actually sue them
- for fucking up in the lab. So they have no scientific responsibility
- whatsoever.
- (6) Nowadays, they sample less than 20% of the electronic
- products on the market of a given type (receivers, radios, vcrs,
- speakers, etc.)
-
- The only thing CU is good for is to get a rough feel for what brands
- you should be looking at / listening to. That's IT!
-
- That's my diatribe on Radio Shack and Consumer Reports.
