Seems like this is a discussion of apples and oranges.
I have no doubt that the Radio Shack speakers are great speakers. I spent many happy years with optimus speakers for my stereo.
I'm also fairly sure that they aren't designed for use as nearfield monitors.
I used to mix with my best speakers (Klipsh- or however you spell it- book shelf speakers) and they sound great. I even figured out how to mix on them and have my mixes work OK on most other stereo systems.
But when I A/B them with
the Event PS6 studio monitors that I use now there is simply no comparison. The PS6's don't really sound that good, but I can hear each instrument in exquisite detail. And I can hear them fighting for space in the mix.
When I switch back to the Klipsh, all those little details kind of blur together and the mix sounds "better." When I fix those problems on the PS6's, the song sounds more cohesive back on the Klipsh, which still sound great.
There is just a huge difference between a speaker designed for home listening and a speaker designed for reference monitoring. In my mind, you can't really compare them at all. Some home speakers work better as inexpensive monitors than others do, but I kinda doubt that any speakers designed for home steroes are going to give you the accuracy that monitors are designed for.
Like screw drivers and hammers- both made of metal and great for what they do, but they don't really do the same thing.
Incidently, when I was shopping for monitors I did listening tests to a bunch of them all side by side. You'd be amazed at how different they sound! Seems like monitors (or the speakers you are using as monitors) are a matter of getting something you like and learning how to accomodate its particular sound.
Take care,
