I use a Mackie 808s powered mixer with 300c Mackie 2-ways. I use an EV Sxa121 12" sub and it just fills out the sound immensely. I hardly ever have my mixer turned up past 6 and the sub lets me dial down a little further. It ads enough body to make me want to carry it around; it's about the same size and weight as the speaker, about 30 lbs.
