Here is the open secret of projectors: the built-in speakers are almost always terrible. A 100-inch image with phone-quality sound is not a home theater. It is a disappointment. Budget for audio from day one; it is the highest-impact upgrade you can make.
The three sensible paths
- Soundbar: the simplest real upgrade. One box, one cable (HDMI ARC if your projector supports it), dramatically better than built-ins. Ideal for living rooms and bedrooms.
- Powered bookshelf speakers: a pair of self-amplified speakers gives you true stereo separation and fuller sound than any soundbar at the same price. Great for desks and small rooms.
- AV receiver + passive speakers: the full home theater route, 3.1 or 5.1 surround, real bass, room to grow. More money and more wires, but nothing else sounds like it.
What to watch for with projectors specifically
- Audio delay: Bluetooth audio from a projector often lags behind the picture. A wired connection (HDMI ARC, optical, or aux) avoids lip-sync issues. If your projector lacks Bluetooth entirely, pair the speaker to a streaming stick in the projector's HDMI port instead.
- Volume control: make sure you can control the external speaker's volume conveniently, ideally through the projector remote via HDMI-CEC/ARC.
- Placement: sound should come from near the screen, not from behind you at the projector. Center-channel clarity matters more than rumble for dialogue.
- Outdoors: open air eats bass. A portable PA-style speaker or a punchy portable speaker (wired in, to avoid delay) beats a soundbar outside.
How much should you spend?
A good rule of thumb: allocate roughly a third of your total budget to audio. A $600 projector with a $200 soundbar will make you happier than an $800 projector with no audio plan.
