Some background information
There are many tips on mastering music properly in music magazines such
as Sound on Sound and Computer Music. Here are a few of mine...
Referencing of different systems
During music creation it is really important to
periodically reference
your music on different sound systems so you end up with a piece of
music that sounds balanced on lots of different systems. Your music
will probably end up being played on lots of different systems, most of
which are not ideal, sometimes not even stereo! I used to create stuff
that sounded perfect on my old disco speakers (below) but absolutely
shockingly awful on anything else!!
I ended up jumping from the studio to the hi-fi downstairs (to test
quality) to the car (to test bass :) ) and back again and the music was
much more acceptable.
Now I have two monitor systems, one high end professional, one low end
hi-fi (with a switch between the two) and the headphones. From time to
time I will play work in progress in the car as well. I found playing a
track out of the studio is a great way to sort out how I am going to
progress with it if I have run out of ideas and can't get into it any
more.
Stereo imaging
I always use head phones at times too, to check stereo imaging it is
essential because your ears are intimately glued to their respective
channels and any affects the room has on the sound are eliminated. I
found a nice pair of Sennheiser HD 570s which my ears really liked, but
everyone's tase is different. Any sounds in your mix which may be a
little too hard panned on the speakers suddenly become very obvious on
the phones giving you bount of headaches and dizzyness forcing you to
sort them out!
Bass
Using a good pair of monitors with good bass, or a sub can really help
develop good bass lines but dont forget your average punter (unless you
supply sound systems to all your fans(!)) will probably have something
uncapable of reproducing your deeeeep bass - or certainly not quite how
you intend so it's really useful to audition on some small book shelf
speakers (like the diamonds) to see if your bass is lost.
To "find" a bass again, try adding a higher pitched sound or tone onto
your bass to it is more mid - compatible too. Another thing I found
really useful is playing with distortion which can add good effects to
the sound as well as add a lot of higher harmonics. Waves Maxxbass looks like it could really help here as it does exactly that - adds higher harmonics and reduces low fundamentals, so even tiny systems can give the impression of enhanced bass. I have avoided buying this plugin as I have a concern it will make me rely too much on the technology to correct my "bad mixing" and optimise my track for one type of system only to find it does not sound too good on another system. so yes - yet again its the hard way for me :)

Panning
Panning of stuff is important to make a mix sound life like and more
stereo, but make sure bread and butter sounds - bass line and often
bass and maybe snare are centered. The centering of bass means the
system playing the track can deliver max bass using both its channels
and when it comes to deep sounds you can't tell if its coming from left
or right anyway.
Waves and other plugin manufacturers have plugins which can visualise the panning and spacial utilisation of a sound and it can be quite elightening to view your track is something as simple as the "scope" plugin (free with Cubase 5) set to analyser mode to view how mono your track actually is!
