Reply to QSC K10s w/ KW181 Advice

I was looking to buy my first set of PA speakers, but am limited in my budget. I was looking forward to rocking with a pair and a sub, but that is out of the question for now. I have about 1,850 to spare, and am curious weather I should buy just a pair or maybe one (going mono) with a sub.

I'm not sure how the K10s work with their lower frequencies or if even buying a sub is necessary. I'll be working with primarily house parties and rooms between 1500-3000SQ FT, depending on where and with who I'm working with. I'm also required to buy two stands if I am to go with just the pair without a sub, but if I'm to buy a single K10 with a sub, the pole is included.

So either:

K10s and purchase two stands

OR

Single K10 with KW181 sub, comes with one pole on top of KW181.

Keep in mind, I need this very soon, so I'll be saving to order in another sub/speaker for a more complete set later on down. I just don't want to commit to a cheap pair with sub and cry about down the line.
