Most projectors have small built-in speakers, but they are rarely loud or clear enough for comfortable viewing
The short answer: yes, most projectors sold today include a speaker, but it is usually a small one rated between 1 and 3 watts. That power level works for a quiet office or classroom where the projector sits close to the audience. For a living room, basement, or any space larger than about 15 feet across, the built-in speaker will sound thin and distant, and you will likely want an external speaker or soundbar instead.
The reason manufacturers include speakers at all is convenience — you can plug in a projector and show a video without buying anything else. But that convenience comes with a real trade-off: a speaker small enough to fit inside a projector case cannot move enough air to fill a room with sound. If you plan to watch movies, play games, or present to more than a handful of people, plan to add audio equipment.
Key Takeaways
- Most projectors include a built-in speaker rated between 1 and 3 watts, suitable only for small, quiet rooms or presentations to fewer than 10 people.
- Built-in speakers sound thin and lack bass because the speaker itself is physically small and the projector case does not provide room for sound to develop.
- External speakers, soundbars, and home theater receivers all connect to a projector via 3.5mm audio jack, RCA cables, or HDMI, depending on the projector model.
- If your projector has no audio output port, you can route sound through the HDMI source device (like a streaming box or laptop) instead of the projector itself.
- Budget projectors under $300 are more likely to have speakers; premium projectors often omit them entirely, assuming buyers will use separate audio equipment.
Why projector speakers are so small and weak
A projector is designed to be compact and portable. Adding a large, powerful speaker would make it heavier, bulkier, and more expensive. The speaker that fits inside a projector case is typically a single driver — often just 1 to 2 inches across — mounted in a plastic enclosure with very little internal volume. That small enclosure cannot resonate or amplify sound the way a proper speaker cabinet can.
The result is audio that sounds hollow and tinny, with almost no bass. If you have ever heard a projector speaker at full volume, you know it sounds like a small transistor radio, not a television or home theater system. The speaker is doing its job — producing sound — but it is doing it with severe physical limitations.
Which projectors actually have speakers
Budget and mid-range projectors — those under $500 — almost always include a built-in speaker. Models from brands like Epson, BenQ, Optoma, and Anker typically have them. The speaker is usually rated at 1 to 3 watts and mounted on the bottom or back of the projector body.
High-end projectors, especially those designed for home theater or professional use, often omit the speaker entirely. Manufacturers assume that anyone spending $1,000 or more on a projector will already own a sound system or will buy one. Some premium models do include speakers, but they are still small and are meant only as a fallback, not as the primary audio source.
If you are shopping for a projector and audio quality matters to you, check the specifications before buying. The product sheet will list the speaker wattage (if present) and the audio output ports available. A projector with no speaker but with a 3.5mm audio jack or RCA outputs is actually a better choice than one with a weak built-in speaker, because it forces you to use proper audio equipment from the start.
How to connect external speakers to your projector
Most projectors offer at least one of these audio output options: a 3.5mm headphone jack, RCA audio outputs (red and white connectors), or HDMI audio passthrough. The method you use depends on which ports your projector has.
3.5mm audio jack: This is the most common output on budget and mid-range projectors. You can plug a 3.5mm cable directly into a powered speaker, soundbar, or amplifier. This is the simplest setup and requires no additional equipment beyond the cable.
RCA audio outputs: Older projectors and some professional models use RCA connectors (the red and white plugs). These connect to a receiver, amplifier, or powered speakers with RCA inputs. RCA cables are inexpensive and widely available.
HDMI audio passthrough: Some newer projectors can send audio back through the HDMI cable to a receiver or soundbar. This works only if your audio device supports HDMI input and if you connect the projector to that device, not directly to the video source. It is less common than the other two methods but eliminates the need for a separate audio cable.
If your projector has no audio output at all, you can still add sound by routing audio through the source device instead. For example, if you are streaming from a Roku, Apple TV, or laptop, connect the audio output from that device to your speaker or receiver, and let the projector handle only the video. This works well and is often the simplest solution.
What external speakers and soundbars cost
A basic powered speaker or soundbar designed for projector use ranges from $50 to $300, depending on size and sound quality. A small powered speaker (5 to 10 watts) costs $50 to $100 and works well in a bedroom or small living room. A soundbar (20 to 50 watts) costs $100 to $300 and fills a larger space with fuller sound. For a true home theater setup, a receiver and separate speakers can cost $300 to $1,000 or more, but that is optional unless you want surround sound and subwoofer bass.
The price you spend on audio should roughly match the price of your projector. A $200 projector paired with a $500 soundbar is overkill; a $1,500 projector paired with the projector's built-in speaker is a waste. A $300 projector with a $100 soundbar is a balanced choice that will give you good video and acceptable audio.
Soundbars versus separate speakers for projectors
A soundbar is a single unit that sits in front of the screen or below it, and it handles all the audio. It is straightforward to set up, takes up little space, and costs less than buying a receiver and multiple speakers. Most soundbars connect via 3.5mm cable or HDMI and work with any projector.
Separate speakers (a receiver with left, center, and right speakers, plus optional surround speakers and subwoofer) give you more control over sound placement and can fill a larger room. They cost more and require more setup, but they deliver better sound quality for movies and games. If you are building a dedicated home theater room, separate speakers are worth the investment. If you are adding audio to a projector in a multipurpose room, a soundbar is usually the better choice.
Projector placement and speaker placement
Where you put the projector affects how well its built-in speaker works. If the projector is mounted on the ceiling, the speaker points downward or backward, away from the audience, and sound quality suffers. If the projector sits on a table in front of the screen, the speaker at least points toward the audience, but it is still weak.
If you add an external speaker or soundbar, place it as close to the screen as possible, ideally centered below or above the image. This way, the sound appears to come from the screen, which matches what the audience sees. A soundbar mounted on a wall below the screen or sitting on a shelf in front of it works well. A powered speaker on a stand beside the screen also works, though it is less ideal than center placement.
Frequently Asked Questions
Can I use any Bluetooth speaker with my projector?
Not directly. Most projectors do not have Bluetooth output. However, if your projector has a 3.5mm audio jack, you can connect a Bluetooth receiver (a small device that plugs into the jack) to pair with a Bluetooth speaker. Alternatively, if your video source (streaming device, laptop, etc.) has Bluetooth, you can pair the speaker to that instead and bypass the projector's audio entirely.
What if my projector has no audio output port at all?
Route the audio through your source device instead. If you are using a streaming box, gaming console, or laptop, connect its audio output to your speaker or receiver. The projector will handle only the video signal, and the source device will handle the audio. This setup works well and is often simpler than trying to extract audio from the projector.
Is the built-in speaker good enough for a small bedroom?
Possibly, if the room is very small (under 12 feet across) and you do not mind thin, quiet sound. For a bedroom, a small powered speaker ($50 to $80) is a better choice because it gives you fuller sound without taking up much space. It also lets you adjust volume independently from the projector.
Do I need a receiver to add speakers to my projector?
No. A receiver is only necessary if you want surround sound or a subwoofer, or if you want to switch between multiple audio sources. For basic stereo sound from a projector, a powered speaker or soundbar that connects directly to the projector's audio output is all you need.
Can I connect a projector to a TV soundbar?
Yes, if the soundbar has a 3.5mm or RCA audio input. Most TV soundbars do, even though they are designed for televisions. Connect the projector's audio output to the soundbar's input, and it will work the same way it would with a TV. Make sure the soundbar has the right input type before buying.
