Can this be used for home theater setup, and run signal from the sub out on my receiver using an XLR adapter?

yes , most receivers have a subwoofer low level (un amplified) RCA output. You could use an RCA X 1/4" TPS . RCA would plug into receiver and 1/4" TPS to Rockville sub. Remember the input on the sub is XLR - 1/4" combo . Which means you could plug either one into same input on subwoofer. You asked about using XLR . You do do that but I'm willing to bet it'd be easy to find a cable with RCA on one end and 1/4" TPS at the other vs RCA on one end and XLR at the other end. Either will work!

I am doing an outdoor dance and will be about 100' from a power source, what size extention cord will I need to power this sub?

I always buy ... #12 AWG...wire extension cord either 100'...or two 50 footers.That size will be more than adequate for most any application around your house or outside.Get two fifties much easier to use a fifty when you need one around the house or outside if you don't require a 100' er.

I have the rbg15. I was thinking of buying the rbg18. Can i run both of these with my peavey pv115d's?

Yes. Depends on how many outputs you have on the mixer. You can run a rca out to dmx cable to the speakers.

Puedo usarlo para monitor de bajo?

No ,yo soy musico y la verdad es tremenda equipo pero para Usarlo DJ systems. La frecuencia del Bajo es mas fuerte y profunda .
