I've been looking and can't find anything anywhere. I have a 3M Mini Projector by ROku, for audio, it has 1, output 3.5mm jack. I'm trying to find some speakers that I can plug in to it that has a sub. I know your typical small computer speakers will work, but I'm trying to find something that can go loud enough to say, Watch the Seahawks game on a 120" screen that a room with 5-9 people can hear the game over the chit chat. I'd prefer 2 rear (L&R) 3 Front (L&R&C) and a sub, but I know that with a 3.5mm jack, it probably isn't feasible. so a sub and 2 LOUD fronts or 3 R,L & Center would also be suffice. I'd like something around 100-200 watts. I'm hoping to keep it under $150. What I'm finding is only RCA type plugs only, but the Roku only has a 3.5MM output jack.
