I mixed on Yamaha HS80m speakers.  Wish I had a subwoofer to really dial in that low end more accurately.  Anyway... I used protools 9 with only avid stock plugins. My interface right now is a Mackie blackbird.  Can't wait to get into analog summing bringing that analog vibe to the mix.  It will be great.   I basically did some type of compression on everything.  Vocal and snare had the heaviest compression to smoothen out the performance.  All the other sources had compression for characteristic choices.  I used a lot of techniques I have seen Fab teach online about when it comes to reverb.  It's slowly but surely changing the way I mix, and I love it.  A mixture of room verb, plate, and halls.  I did very slight bus compression.  But I chose to use a multiband compressor so that I can set the thresholds and keep my naturally eq balance that I had on the mix.  If I tried using a regular bus compression it tamed too much of the highs and muffled the lows so a multiband gave me the gel sound I desired without harsh artifacts.
