Computer Speaker are in fact Near field Monitors with one very special
attribute. They need a perfect shielding. Otherwise your monitor will show you some bizarre
colors and shapes (except you work with
Flat Panel monitors).
Nearfield monitors as Computer Speaker give you the sound you deserve...
The next problem that needs to be handled is bass (depending on
the nature of music you have to mix). Small monitors cannot really move
the base (no matter what advertising noise says).
My absolute favorites (after a lot of comparison tests over the years)
are still the Tannoy-Concentric Speakers. The ones I recommend for
near field monitoring are the System 800 shielded. They are big enough to
get an idea of the base and small enough to fit your desktop beside your
In fact some of the modern near field monitors l became very good
in producing real bass. But only at decent level. When you want to hear
it loud, you still need bigger speaker.
When you have to mix music with deep and loud bass, like Hip-Hop, all
kind of Dance-Music, Pop or Rock, you need speakers, that can move the
air molecules with enough energy, to give you a good impression of what's
going on deep down in the basement.
In practice, that means you need at least a 12" Bass driver.
You can either manage that by getting 2 good shielded Near field
Monitors and a subwoofer or two 12" speaker. Bigger monitor
speakers are not shielded because the magnetic power is too big to allow
effective shielding. But normally they stand away from your screen, so
that should be no problem.
So, if you want to go for a powerful midfield monitoring system take a
look at the Tannoy System 1200.
studio monitor is not really a small box, but when you can manage it
(money-, place- or neighbor-wise), get them. They sound just great at a
fair price and you will have enough power in the lower frequencies.
