My fraternity house is looking to invest in a sound system. The sound system will be used for outdoors and indoors(mainly indoors due to winter). Our budget is roughly 800$.I am not tech savy when it comes to audio equipment, so links or names to good products I need will be greatly appreciated.For the bass I will be building a design from http://www.billfitzmaurice.com/index.html with lab 12s. I do not know which design would be best because there are a lot to choose from, but Possibly the tuba 60 if money allows it. Also, I will need to know what devices I will need to power this sub and what I will need to be able to plug it up to the sound system. Any and all advice will be appreciated, thanks.
