Have you ever dreamed of having a house wired for music in every single room? It's actually very easy to do — and you don't even need the wires. The Definitive Technology W system makes it a snap. Start off with their W7 speaker in any room — it's a compact, cube-shaped powered speaker that offers surprisingly big sound. Connect it to your Wi-Fi® network, control it with your smartphone or tablet, and you'll be enjoying a wealth of music in minutes. Add more speakers or components to play different songs in each room, or stream the same tune everywhere in party mode. The only hard part is deciding which song to play next.

The compact W7 offers dyanmic sound in a unique cube-shaped speaker that's easy to place anywhere.

Let your music follow you, without any wires

Have you ever dreamed of having a house wired for music in every single room? It's actually very easy to do — and you don't even need the wires. The Definitive Technology W system makes it a snap. Start off with their W7 speaker in any room — it's a compact, cube-shaped powered speaker that offers surprisingly big sound. Connect it to your Wi-Fi® network, control it with your smartphone or tablet, and you'll be enjoying a wealth of music in minutes. Add more speakers or components to play different songs in each room, or stream the same tune everywhere in party mode. The only hard part is deciding which song to play next.

Play loads of music wirelessly with your smartphone or tablet

The Definitive Technology W7 offers lots of ways to listen to music. A free app for Apple® and Android™ is your hub for accessing music stored on your smartphone or tablet. You can also stream music from networked computers and music servers. If you're one of the millions of Spotify® Premium subscribers, Spotify Connect lets you access all your favorite albums and playlists. There's built-in support for Pandora® Internet radio and SiriusXM. Plus, you can choose from over 37,000 free Internet radio streams, for a nearly endless supply of music and other programming.

Play-Fi® turns every smartphone into its own music system

The key to the Definitive Technology W7's wireless music capability is Play-Fi. Developed by audio innovator DTS, Play-Fi allows you to send the same song to multiple speakers, play a different song in every room, or let each member of the family control speakers independently with their own device. Play-Fi can transmit lossless audio at CD quality to up to 16 speakers or components on your network. Best of all, the W7 can work with other Play-Fi speakers from other manufacturers. That means you can mix and match different brands of wireless speakers, offering more flexibility than closed systems.

Innovative tri-polar design

When I first saw the W7, I was quite surprised at how small it was. When I heard it, I was jolted by its big, punchy sound. But this compact speaker's story isn't just about volume. The unique tri-polar design features drivers on three sides, evenly distributing clear, accurate sound across a wide soundstage. It's a brilliant design for a speaker that's likely to be used in a kitchen or other room where you're not going to be stationary. The four tweeters ensure you get lots of detail from various listening angles, while the 4" mid/bass driver and dual passive radiators throw plenty of tight bass your way. You'll even get some reflections off of nearby walls, for spacious sound that makes the W7 an impressive music source in almost any room.

Crutchfield Customer Review (What's this?)

Not the easiest to connect. Required firmware updates. Customers service a little weak. The sound quality is definitely worth it. Incredible audio products. No wires so you can move them to other locations at your whim. Great product.



Definitely better options

David from KS on 12/30/2017

Crutchfield Customer Review (What's this?)

I blind bought these based on reviews here, on other sites, and online video reviews and was very disappointed. Firstly because I was told by a Crutchfield adviser that these would work with a PC, which is partially correct. In reality you have to have an Android or IOS device to set them up and play them so although you download their app to a PC, without the aforementioned devices you can not stream music. Just an FYI the app wants all of your contact info and wants to install locator software to track your phone which is completely unnecessary. I was able to connect a 3.5mm male to male phono jack and play them with a direct connection and was completely underwhelmed. I used a Ugreen cable connected to a Toshiba P75-A7200 streaming compressed music and CDs. I tested these speakers with Bach, Steely Dan (Aja, FM etc), Neucleus (Jam on it), David Bowie, Queen, Bela Fleck, and Andrea Bocelli before listening fatigue set in and I had to turn them off. A) they sound no better than a cheap pair of off brand computer speakers from a local big box retailer. B) The are, and I am not exaggerating, no louder than my laptop except in bottom end. Yes I turned the volume up all the way on the unit. C) The instruction manual is totally useless. D) The low end overshadows the mids and highs. E) The app is very poorly designed. I wont even consider Definitive Technology after this experience. They are solidly built and look nice but for the price there are much better options

Pros: Build

Cons: App is poor Sound quality is ridiculously bad. My Toshiba laptop sounds better. Sound volume is poor.

Definitive quality

Crutchfield Customer Review (What's this?)

Been a huge fan of Definitive speakers for many years, and this one does not disappoint.. Provides crisp sound even at volume. Setup was pretty simple with the iPhone app, and had it playing music in no time.

Pros: Great speaker that doesn't take up much space. Provides plenty of audio to fill the room, and love how my music collection sounds through it.

Cons: The Definitive app is not great, but it's been updated a few times since I got the speaker.. It is getting better for sure..

Amazing sound in a small package.

Jesse from Haddonfield, NJ on 5/6/2017

5 stars for sound... but 1 star for app/compatibility. This really sounds tremendous for it size. Small enough to move when needed (pick up by the base though...) . Quality feels really nice and I'm very impressed with it. Highly recommended. Now for what I found disappointing. Almost no compatibility with Apple products. There is an app for streaming from your iPhone or via a music server, BUT its UI is terrible and it ignores your iPhone playlists. That said, since this speaker still needs to be plugged into a wall outlet, I simply bought an Apple airport express, and connected its audio output into the W7's input. Now I can bypass all of DT's tech and rely on Airplay, which is way more convenient for my household. I guess all of this is a moot point if you're a non-Apple user, but for those that are, be aware of the limitations. A cheap AP express can solve that however...

Pros: Great Sound, very stylish.

Cons: No Airplay compatibility, terrible iPhone APP.

Sounds and looks amazing but app used is terrible.

James from Missouri on 4/22/2017

Crutchfield Customer Review (What's this?)

The sound of this little guy is amazing. Setup is kind of a pain. You can not connect directly to it. You have to first download an app which is not able to let me play the songs off my Nexus 6p phone. Then you have to connect the speaker to your home network. Pros: Great sounding speaker. Small and compact. Seams well put together and quality material. Looks good. Cons: App is not the best. You may not be able to listen to songs purchased on the Android sure. Setup is a pain. You can not use stand alone without a home network.

Pros: Sound, looks, and size.

Cons: Setup and app.

Amazing sound!

Evan from NJ on 4/21/2017

Wow! What amazing sound from a small wireless speaker system. Along with the Play-Fi app (both IOS and Android), set up was easy. Easy to use features - allows me to stream all my music sources from my devices to the speaker. A very worthwhile investment!

A little hard to setup with sound bar but great quality sound and fidelity



Great sounds, awesome look

Chris from Egg Harbor Township NJ on 11/5/2016

Crutchfield Customer Review (What's this?)

Great speaker, sounds if awesome for a wireless speaker, first and won't be last. Connection is sometimes an issue, but this is better when the Wifi location is closer to the speaker.

Pros: Sounds, look, design

Cons: sometimes looses connection

Great clarity and musicality with minor flaws

Frederick from Redmond, WA on 10/24/2016

Crutchfield Customer Review (What's this?)

I bought the Definitive Technology W7 to replace my Sonos Play:3 speaker as I needed a system that could handle higher-resolution audio files for easy listening. I already have a hi-fi system set up when I really want to critically listen to music (which is not terribly portable), and it's nice to be able to play most of my audio files throughout the home now.The set-up was easy and fairly straightforward, and the sound seems more clear than my previous Sonos speakers. I also wanted something that wasn't tied down to one company, and the ability to connect via play-fi with speakers of other brands was a definite plus for me. I put two of them together as a stereo pair, which has sounded wonderful. I'm not a bass-head, but I do wish there were a little more bass, but, I can't expect that given the size of the speakers. I would have also liked an inclusion of bluetooth for when I have guests over, so that they could connect their music, but, that's really just nitpicking. Overall, I love the sound and the physical design of the speakers. My only real issue with the speakers is that the play-fi software to run it is not as intuitive or flexible as I might want, such as not being able to stream some services to a stereo pair of speakers.

Pros: Small. Great Clarity. Good support of audio formats. Nice design. Easy to make a whole-home audio set-up. Can create stereo pairs with speakers. Can be integrated with other play-fi devices from different companies.

Cons: Doesn't support DSD. No bluetooth built in. Can't use stereo pair with certain sources. Play-fi app can be a little buggy.

I have owned Definitive Products for many years . Purchasing the W7 was easy with Crutchfield and the sound is amazing !!



Great speaker!

KSR1971 from Florida on 12/31/2015

Crutchfield Customer Review (What's this?)

Absolutely love this speaker. I started with 2 and ended up buying 3 more. I have two paired as a stereo pair in the bedroom and the living room and the sound is amazing. The production of lows, mids, and highs is superb. The W7 stereo pair can be used to augment the W Studio soundbar for music but my only wish is that you could use them as a rear set with the soundbar for true wireless 5.1 surround on movies. Most of the app bugs with earlier reviews have been resolved.

Pros: Easy to set up. Fantastic sound. Better sounding than Bose and Sonos.

Cons: App still has some minor bugs. Cannot use a stereo pair as rears with the soundbar for true 5.1 surround.

fantastic sound

Matthew S from Dunedin, FL on 5/21/2015

Crutchfield Customer Review (What's this?)

We shopped around for wireless speakers for the house and compared the different products and brands. We looked and listened over the past 4 months and kept coming back to the Def Tech W7. Amazing sound quality across the music genres. Design of the unit let's us hear music in several rooms. I finally bought it for my wife for Mother's Day...everyone is happy.

Pros: Nice design, fairly easy set up and app download. Compatible with several other speakers to expand around the house. And of course fantastic sound quality in every type of music and news.

Cons: Haven't found any yet. The price is worth the sound quality.

Great speaker, limited features (for now)

CSH from Virginia on 5/20/2015

The Def Tech W7 is easily the best sounding wifi speaker out there. That's why I bought it. I have a small living room, with no real home theater set-up, so the optical input in the W7 allows me to play the TV sound through a high quality speaker. The wireless capabilities are good, but not great - yet. If you are a paid Spotify user, its excellent, as you can stream directly from the Spotify app on your mobile device or computer. In terms of streaming native content from a computer, it leaves plenty to be desired. I didn't mind setting up a media server like Plex, but not everyone will be up for it. Either way, the sound is fantastic and it's a much more future-proof option than anything made by Sonos.



DefTech W7

KevinDB from California on 12/12/2014

Demo'd the W7 and W9 and was quite impressed. I wanted the W9 but at that price point you can build a quite nice bookshelf system with room to expand. The W7 sound is much, much better than the S2. Perfect for our use case, where we want to hit a button and play music in the kitchen and small living room, and a small footprint. It does sound bigger than it's small size would imply. Of course it is not capable of reproducing lower frequencies, I believe it's somewhere around 65Hz, but this is as expected for the driver components and size. I'm really glad to See Polk Audio and Definitive Technology bring PlayFi to the table and knock it out with quality speakers. I know there are other options with PlayFi but these are the best for now! I will be keeping my eye out for after Christmas sales to maybe pick up a second W7.

Pros: -great sound for the intended purpose -great design and small footprint -ease of use with PlayFi -ease of future expandability with PlayFi devices -best in class for this niche in my opinion

Cons: -PlayFi is new, and as such the applications are not very robust. Disconnects do happen from time to time. -Perhaps a little bit pricey -No bluetooth option -No tone management option

Blown away!

Melvin from Tenn on 10/22/2014

I heard this at Magnolia and could not believe how incredible the performance was. The sound was so deep and pure. Great bass from such a small package. The design is better than the sound, love the control panel!!! I am on a budget so I picked up the Polk S2's and I love them, but there will be one of these in my home before Christmas.

Pros: Sound and Look. Rock solid build. Serious audio performance. Sleek.

Cons: I wish it was a little more affordable.
