The tone match mixer has an aux out that is fantastic for feeding an additional sub for those of you that miss that thump. I've tried it at home, and it works great but i have NEVR needed it at work...weddings, school parties, outdoor picnics for 400+ etc .... I just donlt play for that type of crowd. If you need more ooomph ... get a small sub and use the aux outs....you'll keep the simplicity, the clarity and you'll add the thump.
