Reply to Hey all, newbie with some external audio questions...

Well, this is my second post I beleive it is here on the community s. Ive been mixing for about 8 months or so and have come a long way. My only gear is a laptop with touchOSC for android. I was using my line out into my old 5.1 home theatre setup but the receiver went bad so now I have it going to my fender bass amp which can ROCK the house but, its only 1 speaker obviously and that drives me crazy. Anyways, I am believeing of going with a Numark N4 and am wondering what I should do for external audio. Reciever, speakers, I dont know what to go with in this situation. This is just a hobby of mine so It is pretty much just house use unless a coworker or something wants me to Dj a party. Where should I start with the audio? Any help would be much appreciated.
