Bose Companion2 Series III speaker system

Desktop convenience

Bose's TrueSpace® signal processing is the key — it creates a broad soundstage from speakers spaced no further apart than the width of your computer monitor or laptop. You'll hear improved warmth and detail from your MP3s and streaming audio, and added punch from your computer games and DVDs. Two sets of audio inputs let you hook up an additional source, like a portable MP3 player, without having to disconnect the speakers from your computer. A handy front-panel headphone jack makes private headphone listening easy for those times when you don't wish to disturb others.

Product Research


Powered Computer Speakers: The Bose Companion 2 is a two-piece computer speaker system (Left & Right speakers) that reproduces full, natural sound at your computer. The Bose Companion 2 will dramatically improve the audio from your computer, while its sleek, space-saving design complements your computer environment.

TrueSpace Technology: The Bose Companion 2 speaker system features TrueSpace stereo signal processing circuitry. This proprietary technology helps maximize audio performance by widening the image of closely placed speakers, making the audio seem to come from a soundstage wider than the two speakers.

Ported Cabinets: Each speaker features a rear-panel 3/4" diameter port to provide clearer, deeper bass from a small enclosure.

Automatic Tone Adjustment: The Companion 2 speakers automatically adjusts the tonal balance to give you rich audio performance at practically any listening level.

Dual Inputs: The Bose Companion 2 has two 3.5mm aux inputs. These dual analog inputs allow you keep the speakers hooked up to your computer, while you use the second input to hook up another source, such as a portable audio device. The dual 3.5mm aux inputs are located on the back of the same speaker. One 46" stereo audio minijack cable is included.

Headphone Jack: The right speaker is fitted with a front-panel 3.5mm headphone output; the speakers are muted when headphones are plugged in.

Tethered Speaker Connection: The left speaker features an attached 6' audio cable with a proprietary connector which plugs into the rear-panel proprietary port on back of the rear speaker (labeled "To Left Speaker").

Volume Control: The volume control is conveniently located on the front of the right speaker, giving you easy access. On your computer or an optional sound source, set the volume at about two-thirds the maximum volume. Then use the knob on the right speaker to adjust the volume as you listen.

Angled Design + Magnetically Shielded: The angled design of these speakers allows them to direct sound upward toward a seated listener. So placing them on a desktop is a good choice. Magnetic shielding protects your computer monitor from interference when the speakers are positioned close to it.

AC Power Supply: The Bose Companion 2 operates off of standard household AC current using the supplied AC power adapter. The AC power adapter plugs into the back of the right speaker.

  • Input: 100-240V ~ 50/60Hz, 600mA
  • Output: 12V - 1800mA

Q & A

Customer Q&A

Crutchfield asked  
Why did you buy this?

compact size [ Craig  Nov 13, 2018 ]
One of the tweeters in my old Logitech 2.1 speakers died so the left sounded quieter than the right without playing with the balancing. I have a limited amount of space on my desk so I chose these to fit the space along with the Top Seller status and Bose reputation. Hoping they work out! [ Nicholas  Oct 06, 2018 ]
Bose brand and low price [ MICHELLE R  Sep 06, 2018 ]
Brand Name. I have various Bose products and all perform well w/o problems. [ Frank  Sep 03, 2018 ]
Quality and price [ John  Aug 19, 2018 ]
it's Bose and the reviews were strong. [ Brad  Jun 13, 2018 ]
BOSE KNOWS! [ LINDA  May 16, 2018 ]
A cousin of my wife has these Bose speakers and she really likes them. I am surprising her with these for her birthday, thanks to Crutchfield for great product selection and great delivery and price. [ James  May 09, 2018 ]
I have 4 other Bose products in my home. The sound is next to perfect.I originally purchased a set of 901's in 1970, unfortunately i had to much power pushing them and blew them. I have had no issues with the replacement ones and the other Boes systems are next to nothing. [ ROBERT M  Apr 10, 2018 ]
Quality. [ Paul  Mar 23, 2018 ]
I got the hundred dollar Mackies for my laptop for use in the upstairs den cause I liked the frequency specs. Nothing listed for the Bose. Plugged the Mackies in in the kitchen and there they will stay. They absolutely rock. The Bose being slightly smaller will now go in the den a( little less obtrusive) and with the money back Crutchfield guarantee behind the Bose name - no brainer. [ Mr. Joseph  Feb 16, 2018 ]
I chose the Bose Companion 2 Series III because I owned the Series I version. Was extremely satisfied with their sound until they finally died. So, the logical choice was to replace them with the newest version. Heard them in a Bose store and they deliver the same great sound as the ones they are replacing. [ IVAN  Jan 30, 2018 ]
Bose is the best in speaker quality. Purchasing Bose means I won't HAVE to replace them unless I want to. [ Terry  Nov 21, 2017 ]
replacing pair received as gift from father. great compact size with robust sound [ jeffrey john  Nov 20, 2017 ]
Price & Ratings [ Paul  Nov 14, 2017 ]
because of Drummer [ curt  Oct 31, 2017 ]
I have dealt with Crutchfield before on different products and have always been happy with their products, prices, and the customer support that they provide. LT was the reason that I made the choice that I did. [ Mark  Oct 27, 2017 ]
I love Bose speakers. [ D  Sep 23, 2017 ]
Quality product reputation at a good price! [ Peter Merton  Jul 28, 2017 ]
I have researched various computer speakers and decided to go with Bose based on my previous experience with their products. I chose this particular system due to limited space I have available for them (I like their small footprint). They will be used to monitor the audio when I'm transferring my vinyl to digital format. [ Barry W.  Jul 14, 2017 ]
inexpensive and great quality [ robert  May 28, 2017 ]
Bose quality and reasonable price. [ Anthony  May 14, 2017 ]
Number one is because I can buy it from Crutchfield at a competitive price. Number two is because of the service Crutchfield gives. Number three is because of the technical service Crutchfield offers. Number four is their advisory staff which I find most helpful. Number five is because they are good people to do business with. Thanks Crutchfield for being there. [ Tom  Apr 12, 2017 ]
Good price for Bose computer speakers. [ Rufus  Apr 10, 2017 ]
I have two more of this speakers....they are very good to use on computers....the only complain is that they have a very short audio stereo cable...however i got cables of 10 feet long for ten bucks each....problem solved... [ JUAN  Mar 30, 2017 ]
Highly rated speaker system at a great price produced by a company famous for top quality audio gear. [ STEVEN  Mar 29, 2017 ]
Eddie recommended [ Ronald  Jan 22, 2017 ]
Best quality for the amount I was willing to spend. Also, love the free two-day shipping... Amazon wanted to charge me about $15. Their loss :) [ Bryan  Jan 16, 2017 ]

good sound and price is right. [ Leonilo  Dec 22, 2016 ]
Wanted a nice pair of speakers to kick my PC up a few notches while playing and watching digital content. The brand and the price make this a great deal. [ Richard  Dec 06, 2016 ]
Bose is a trusted name in speakers and I needed good speakers for my wife's computer as she has a lot of music and concert videos to listen to. [ Brad  Dec 06, 2016 ]
Wanted new speakers that sounded better for my computer. [ F  Nov 22, 2016 ]
Owned the series 2 and where great [ christian  Oct 25, 2016 ]
Bose reputation at a fair price. [ Jeffrey  Oct 13, 2016 ]
1- I have all Bose speakers & products in my house; they are the best! 2- The prices was right; needed a low cost speaker for my office computer. [ Parviz  Sep 18, 2016 ]
Bose has a good reputation for speakers. These are compact and look very nice. [ Steffen  Jul 15, 2016 ]
These sound awesome! Very impressed! The sound is crisp and does an excellent job [ MIKE  Jun 05, 2016 ]

I Love Bose They Have The Greatest Sound. [ Rick  Mar 14, 2016 ]
for the price & bose wow.looks like a deal to me [ ralph  Mar 08, 2016 ]
Had positive feedback from friends... [ Alfredo  Mar 01, 2016 ]
No doubt because of the BOSE name and that I sound tested in a BOSE store. Replacing a pretty decent CREATIVE LABS T2900 sub system that's 6 years old. Excellent sound but sub distorts, even after trimming, at mid to peak volume. I was going to order from Amazon at same price with free ship but I just think Crutchfield is benchmark for Audio/Video expertise. [ James  Feb 28, 2016 ]
I was looking in Google for a SONY Multimedia System, but couldn't find any in the US, and got a hit from Google for your Superb BOSE System. They look almost like my sister BOSE System, which Sounded Great. I am praying that they will Sound Great too with my SONY VAIO ! Thank you very much, Crutchfield ! My father and I have been your customers from time to time. I hope in the LORD to buy you more Hi-Fi Tech in the future ! [ L  Feb 25, 2016 ]
they sound good [ Paul  Feb 11, 2016 ]
good sound system [ Mark  Feb 01, 2016 ]
compact ,good quality,reasonable sound [ Z  Jan 31, 2016 ]
I have difficulty hearing and hope these will alleviate the problem. [ Patricia A.  Jan 03, 2016 ]
Most reasonable for its intended use. [ P  Dec 30, 2015 ]
Good sound [ R  Dec 19, 2015 ]
Great quality for the price [ michael  Dec 17, 2015 ]

Recognize the name and price point was favorable to me. [ Jeffrey  Dec 10, 2015 ]
Great sound. [ JAMES  Dec 09, 2015 ]
Value and name brand. [ Matthew  Dec 09, 2015 ]

7 questions already asked

Regardless of horizontal or vertical placement it should sound the same. The speaker shoes add some bass response. But if you really want to improve sound for a computer invest in audio engine 2 worth the price. [ william  Sep 29, 2016 ]
I'm not sure that really matters. Wouldn't the sound be produced all the same? I'm no expert but I think you'll be ok [ ERIC T  Sep 28, 2016 ]
I don't have the same space issue, but these should work just the same on the side. Just remember that there is a slight angle on the side, so the speaker will have a slight upward angle - almost identical to the angle for the vertical position. [ David  Sep 28, 2016 ]
awesome for the price! [ DAVID G  Jan 05, 2015 ]
I assume that they stay on. There is no indicator light, which would be nice... I usually try to keep them turned off when not in use. [ GARY M  Jan 05, 2015 ]
I do not believe the unit powers down. However I would imagine it draws very little current when not active. These are very good speakers. I use them all day at work. [ charles  Jan 05, 2015 ]
Hey Marc, The speakers are on all the time unless you turn the knob counter clockwise to power them off, However, if left on and there is no active input signal received, there will not be an annoying sound. So you can leave them turned on at all times,since the volume/mute/sound controls can be controlled through whatever device is connected to the speakers. I hope this helps. [ J.  Jan 04, 2015 ]
The volume knob when turned all the way to the left is the on/off switch. To answer your question if the switch is on all the time the speakers are powered. [ BARRY J  Jan 04, 2015 ]
I forwarded your question to an Advisor and they responded with the following: I am unaware of any extension for the left speaker audio cable. Bose uses a proprietary connection for that. If they make one, you are probably going to need to get it from Bose. You can contact their service and parts department at 800-367-4008. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy  Jul 21, 2014 ]  Staff
Yes, they'll plug into any device with a 3.5 millimeter headphone jack. [ Vincent  Apr 09, 2014 ]
The speakers plug into anything with the small audio out plug like a headphone out plug .they work on my Apple IPad headphone plug and I have them plugged into the same sized audio out plug on the back of my flat screen TV . [ MICHAEL J  Mar 17, 2014 ]
Hi Dale: I don't know. These are self powered speakers that accept only 1/8 inch stereo jack. So I don't see how to connect the Kindle to them. [ Harry  Mar 16, 2014 ]
If ur kindle has a audio out put then answer to ur question is yes. [ GERARDA  Mar 16, 2014 ]
I am not 100% sure but I don't see why it shouldn't as it's power source is totally independent of your Kindle. [ FRED  Mar 16, 2014 ]
I am not familiar with the kindle, however if it has a headphone "out" plug in like on your computer or almost everything else now a days it will work and sound sweet [ ROBERT  Mar 16, 2014 ]
No idea. Don't have a Kindle and you did not say which model you have. Seems there are several models with different possibilities. I'm using my speakers for computer. [ Beverly  Mar 16, 2014 ]
yes if your kindle has an audio out earphone jack . [ MARVIN  Mar 16, 2014 ]
Everything you need to connect these to the headphone jack on your computer will be included. [ Vincent  Apr 09, 2014 ]
Open the box and hook them up. It's as easy as that. They are great speakers I use when watching blu-rays on my computer or listening to music. Great for gaming too. [ Chris  Mar 01, 2014 ]
Everything is included in the box to hook it up to your laptop. [ Jared  Feb 28, 2014 ]
Everything you need is in the box. You can definitely hook these up to your laptop and be ready to listen immediately. There are some options you can consider in the future: e.g.- You can buy a longer cable if you want to spread the speakers out farther than 6 feet. Or you can buy an extra cable if you want to leave the speakers hooked to your laptop while attaching a MP3 player to the auxiliary input. [ Mark  Feb 28, 2014 ]
There is a basic mini-plug to mini-plug cable in the box that should suffice. If you want a higher-end cable, look at the Monster Cable AI 800 MINI-7. Good computer speakers! [ Russell  Feb 27, 2014 ]
Sorry. I bought as gift and don't know. [ RICK  Feb 27, 2014 ]
Everything's in the box: power supply, speaker-to-speaker cable, and a stereo cable that links the control speaker to the 1/8" headphone jack on your laptop. [ Vincent  Feb 27, 2014 ]
Yes, everything is in the box and ready to go. However you may want to buy a longer audio cable that connects to the computer. [ weldon  Feb 27, 2014 ]
Everything you need is in the box. UNLESS, you plan on adding something else (ie. mp3 player, etc.), then you would need a cable. [ GREG  Feb 27, 2014 ]
Everything is indeed included. The Audio input cable plugs right into the headphone jack of the laptop or PC. It is a short cable----only around 36 inches; I'm sure it can be extended with any standard compatible cable. The system has an awesome sound, you will love it! W [ WILLIAM  Feb 27, 2014 ]
My wife was extremely pleased with the Bose Speakers. From unwraping her birthday present and cranking up the quality sound system was less than 5 minutes. Everything you will need is there. [ DAVID G  Feb 27, 2014 ]
Everything is in the box and they are a great set of speakers by the way. [ Eric  Feb 27, 2014 ]
Everything was with it . Had it up & running within 5 minutes. That even including her unwraping the birthday paper! [ DAVID G  Feb 27, 2014 ]
Everything we needed to connect to our desktop was in the box! Great speaker system, Great sound! [ BARRY M  Feb 27, 2014 ]
I bought the speaker set as a Xmas gift for my daughter across the country where they were shipped direct. She is very happy with them and, as far as I know, did not have to buy any add'l material. [ David  Feb 27, 2014 ]
Everything you will need is in the box. I use these on my laptop and they sound much better than the laptop speakers! [ Hugh  Feb 27, 2014 ]
Package is complete. Nothing else required for hook-up. Speakers are top quality, good sound. [ CALVIN  Feb 27, 2014 ]
Yes, everything I needed was included. The system has three cables included, AC power, cable to other speaker, and mini-RCA (I think its called) to connect to my PC. This is a great speaker set, I am very happy with it. I use them all day while I work at my PC. [ charles  Feb 27, 2014 ]
I bought these with the intention of using on my new laptop and is just recently discoverer I have not been able to use yet because the laptop is equipped with Windows 8 and I can't do a thing with it. If I had bothered to check my desktop at work I would have realized we are on Microsoft Windows 7 Professional and that is what I should have bought likewise. I have to get in touch with HP tech yet to see if they can bring it down to Micro 7 remotely or if I have to buy the software and reinstall. I received new desktop last October and that has had me literally "learning how to walk all over again" because I have to go through more steps to do the same thing, such is life.... [ JOHN  Feb 27, 2014 ]
Everything is in box and ready to go. [ JAMES  Feb 27, 2014 ]
It is complete for your application. [ GREG  Feb 27, 2014 ]
Set the TV to a comfortable volume, then use the volume knob to adjust to the best listening level. [ Vincent  Apr 09, 2014 ]
I've only used the knob. Sadly there's no remote control device, [ OZELL  Mar 10, 2014 ]
I am currently using this pair of speakers on my computer, and I can adjust the volume thru the computer controls and the volume knob. As far as working with a TV, I think it will depend on the model of TV you have. On my flat screen, when I installed a speaker bar using a fiber optic cable, the out-put volume of the TV was locked in the middle of the volume range and I can only adjust the volume with the speaker remote. But that might just be my model of TV [ Raymond  Feb 22, 2014 ]
Set the TV volume at a comfortable listening level, then enhance the sound quality by turning on the Bose. Then when you adjust or mute the sound through the TV remote the input to the Bose speakers is affected and will adjust too. [ GARY  Feb 21, 2014 ]
I do not believe these speakers will work with TV volume. They are made for connection with a computer. But to answer your question more properly, please contact Bose product support on the web. [ Frank  Feb 21, 2014 ]
Either way. If you want to use the volume control on your computer or TV it's best to leave the volume on the speaker turned up high to allow full range from the source control. [ LYN D  Feb 21, 2014 ]
Mine are hooked up to my computer (Mac) and the speaker volume can be adjusted by changing the sound volume on my computer. [ BRIGITTE  Feb 21, 2014 ]
Only the knob on the speaker [ PETER  Feb 21, 2014 ]
I only have them hooked on my computer and you can do both...from the speaker anf media player. I assume that if you installed them directly on your tv they would act the same. [ ROBERTO  Feb 21, 2014 ]
Yes, power must be applied in order for these speakers to work. [ Vincent  Apr 09, 2014 ]
Yes, these speakers need to be plugged in to a wall outlet. They create nice powered sound which could not be generated by a computer plug in. [ JAVIER  Dec 27, 2013 ]
Yes, you will need to plug them in to an outlet. [ MARK A  Dec 27, 2013 ]
Yes [ Phil  Dec 27, 2013 ]
Yes, they have to be plugged into the wall outlet. Otherwise they wont have any power to produce sound. [ J.  Dec 26, 2013 ]
Yes, it does need to be plugged in the wall out let. Great speakers! [ CHRISTOPHER W  Dec 26, 2013 ]
Yes, but you will love these speakers. The juice is worth the squeeze. [ PAUL  Dec 26, 2013 ]
Yes [ WILLIAM  Dec 26, 2013 ]
Yes...they are not battery powered [ ROBERTO  Dec 26, 2013 ]
Yes...they are not battery powered [ ROBERTO  Dec 26, 2013 ]
Absolutely. These are powered speakers. [ Arnold  Dec 26, 2013 ]
YES [ LOUIS  Dec 26, 2013 ]
Yes, these speakers are powered and need to be plugged into an AC outlet. [ James  Dec 26, 2013 ]
