I just used 2 DXR10 speakers with an EV SbA760 15" sub. Covered the dance floor extremely well. We played mp3s, sequences from the Yamaha Motif ES, and sang (male and female voice) through the night.

The EV sub works well for my duo. It has built in wheels and only takes a small footprint. We used a 12" DXS last summer. It did a nice job. It was lighter weight than my EV but was awkward to carry and transport in and out of the gig.

If I were ever to replace my EV SbA760, I would seriously consider the QSC KW181. It's about the same weight as my EV with more wattage and an 18"... That should do the trick of me feeling it in my chest!!

When it comes to moving the gear, it's only me... No roadie. Moving it in and out of the van with the most efficiency is crucial.
