Canadian projector buying guide
Where does projector sound come from?
People search things like projector where does the sound come from because the sound setup is the most confusing part of home theater. Some assume the sound is built inside. Others think they need a speaker. The truth is simple. The source of sound depends on the projector model that you choose.
Projector sound can be internal or external. Many projectors have their own built in speakers. Most projectors also have output paths to external sound devices.
The S7 includes a built-in speaker and lists Bluetooth connectivity. Check its supported audio-output functions and the receiving device; Wi-Fi availability alone does not establish external-speaker compatibility.
Why built in speakers exist in projectors
A built in speaker makes projection easy when someone is just trying to watch something quick without setup. For example a child playing cartoons in a bedroom. Or quick presentation audio in a small office.
The Boss S7 provides a speaker inside so the user can get a full media experience right away. They do not have to set up external hardware if they do not want to. They just power on the device and audio comes out from the projector housing.
Built in sound gives quick access and reduces frustration for new users. This has always been one of the top requested features inside entry home cinema setups.
Where exactly inside the projector is the sound system located
Speaker placement varies by projector. Use the model’s manual to identify speaker openings and avoid blocking them or the cooling vents.
This guide does not include a teardown or verified internal speaker-location diagram for the S7. Follow the manufacturer’s external layout and ventilation guidance.
How to assess the audio from your source
Brightness and video resolution do not establish sound quality. Evaluate the actual audio source, supported format, speaker and listening conditions.
A higher video bitrate does not by itself mean higher-quality audio. The audio track, codec, playback path and speaker all matter.
Test sound with your intended source and selected output. This guide does not provide a measured comparison of S7 audio quality against other projectors.
External audio gives the biggest jump in quality
External speakers may improve sound, but size alone is not a quality guarantee. Compare the actual speaker, placement, room and listening level.
Confirm the exact audio outputs available on the projector or source device before buying speakers. Bluetooth, analogue output, HDMI ARC and an HDMI input are different functions.
The projector audio signal will send sound data into the external speaker device and the sound will play through that device.
This is where most users get the complete cinema style feel. User often says adding bigger speakers feels like the picture finally meets the sound.
Why Boss S8A and Boss A5 can also output audio
Even though S7 is the premium model the other Boss projectors can produce sound inside their housing as well.

Frequently Asked Questions
Does the projector sound come from inside the projector body?
Yes. The speaker sits inside the shell and sound is pushed out of a vent area.
Can projectors connect to external speakers?
Check the exact projector and speaker’s supported connection. A listed HDMI input does not establish HDMI ARC audio output, and wired outputs vary by model.
Is built in sound loud enough?
Adequacy depends on room size, background noise, seating and listener needs. Test the built-in speaker and add a compatible audio system if needed.
Where does the audio signal originate in a smart projector?
Inside the media chipset. The Android system decodes the stream then sends audio to the internal speaker or external speaker.
Can a projector replace a TV sound?
Yes when paired with a bigger speaker. Picture size and audio presence become bigger than most TVs.
