When someone asks which projector is best for home theater, the standout answer is the Boss Projector S7 4K Portable Projector. It’s the top selling, premium model built to deliver big screen cinema quality at home.
That said, the S7 doesn’t work for every room or budget. Two other excellent options, Boss S8A 4K Portable Projector and Boss S5A Smart Projector, fill in for different needs.
What Makes a Great Home Theater Projector?
Before choosing, understand the fundamentals for a strong home theater setup:
-
Brightness (Lumens): If your room has ambient light, you’ll want higher brightness. According to buying guides, around 2,500 – 3,500 ANSI lumens works for partially lit rooms.
-
Resolution: 4K (3840×2160) gives sharper detail, especially on large screens.
-
Contrast ratio and black levels: Importance of darker rooms and good optics for cinema-like experience.
-
Connectivity & Smart Features: HDMI ports, WiFi, streaming apps, and ease of use.
-
Throw distance & screen size: Know how far your projector must sit from the wall and what screen size you want.
With those in mind, let’s compare the three Boss models.
