      Wireless Speaker Rocks the House!

      I bought a Definitive Technology W9 to try one out. The sound quality alone impressed me enough, I bought a second one the following week. The W9 has a lot of punch in the mid bass frequency, due to the dual 5 1/4" drivers. The soft dome tweeters produce clear, natural highs. Dialog is easy to understand because the mids are well balanced. An unexpected feature is the DTS communication between the W9, the smaller W7, and the W Studio Soundbar. I returned to buy the W Studio Soundbar. The free app allows you to connect all of the W9's, the W7's and the W Studio's you may own, in a whole house music system that is super easy to use. You can connect virtually any online music stream from Sirius XM to Pandora & many others to any W devices, or all W devices at once! Because I use Apple Airport Express' to convey sound to various rooms throughout the house in an existing network, I plugged an Airport Express into the optical digital input of the W9. The attached photo shows one W9 with the Airport Express sitting on top of the wireless speaker. I HIGHLY RECOMMEND the W9! They sound very similar to the discontinued Bowers & Wilkins W7, which I use and also connect via Airport Express because the wireless receiver in the B&W is very weak & constantly drops a signal. I have recently shipped my B&W for service: that cost a lot, and the B&W suffers from software issues, which the Definitive Technology does not. The W9 is the best sounding wireless speaker I have auditioned & purchased to date!

      We were in the market for a pair of Wi-Fi speakers. Never had any before. Had a pair of hardware 90's-era Hi-Fi Pioneers—beauties. But, they got mad busted yo, so we picked these up. We got these babies home, unwrapped and plugged them in. Pulled out a smartphone and the laptop, downloaded the app. Set up took about 1 minute. Within the time span of 5 minutes of walking in the door, we had streamed music, downloaded music and random internet-nal nonsense pumping through these muthas. They sounded 100% fantastic. Reverb tails. Spatial distribution. Actual low-end you could both feel and hear. Warmth emitting like an electric blanket out of this tiny little box. It is loud as you ever need. If you need it louder, just take it with you. I didn't trust a Wi-Fi speaker, I figured they'd be no gouda. I was wrong. I know nothing. These are simply incredible. We sat and cranked audio majestic-ness for two hours straight. I love this speaker. That's right one speaker. So loud. So good.

      Big Disappointment

      • My Best Buy® MemberMember

      I am a huge Def Tech fan and consumer. My home theater is built around Mythos ST-L, CS9080 center and surrounds, and dual SuperCube 6000s. Even our guest rooms have Mythos SSA-50s. I read the reviews out of curiosity, but I was already set on getting the W9 because I thought the sound would be similar to what I already own and love. I was wrong. The W9 lacks tremendously is the 4k-20k range. The guitar solos sounds muddled, the cymbal and high hat hits are almost none existent. I have listened to it now for about 6 hours hoping the speaker needed a burn in, but it didn't get better. After further investigation I noticed Def Tech doesn't list a frequency response on the W9 spect sheet. After listening to the W9, there is a reason for this. I gave it 2 stars because the Def Tech app I downloaded to set this up was easy and straightforward and the design of the W9 is nice. If the review was only about sound quality I would not hesitate on giving this a 1 star.

      Fantastic wireless speaker

      • Verified PurchaserVerified Purchase
      • My Best Buy® Elite Plus MemberElite Plus Member

      I was contemplating between the W7 and th W9 on my original purchase. I did purchase the W7 and after listening to how good the W7 I had to go back and pickup the W9 since it was on sale. The W9 is even better than the W7 and that was already really good. I wish the W9 came in white like the W7 but I'll make it work in my decor. Easy to setup to the wifi but I found out that to use the Aux input you have to manually select the inputs from the front controls located on the speaker and not from the app. It would of been great if the app had the capability to select the Aux input like selecting the different streaming apps to listen to music. Both the W7 and W9 has this one limitation and no bluetooth capability is one downfall of this speaker, but DTS play-fi works well. Had some intermittent issue streaming from my iPhone 6 but that went away.

      Great sound; poor wifi

      • My Best Buy® Elite MemberElite Member

      Purchased 2 W7's and the W9. The Sound is fantastic, however, the wifi connection and app are unreliable. The reason I purchased was to have the ability to quickly send music to various combinations of speakers in the house. Problem 1: A speaker can only be in 1 group at a time. So, if I want different combinations, I have to delete and rebuild a group each time. Problem 2: Speakers dropped off the network every time I used them and required 2-5 minutes of opening, closing, and restarting the app. It was never the same speaker from problem-to-problem. The bottom line for me is that if I can't have music playing within 1 minute of opening the app, then I'm out. Didn't read about these problems on best buy review; however, I see it frequently on the DT app review. I returned them.

      Wireless Nirvana...

      • My Best Buy® Elite Plus MemberElite Plus Member

      I have been slowly building out my wireless whole home audio system and couldn't be happier with my decision to go with Definitive. The quality of the sound coming out of the system is very good and the ability to move around the speakers at will is another perk. I also really enjoy running multiple speakers with multiple sources simultaneously, or when we are entertaining and need some background music we can select them all for every level of the house. The only real negative I can say is the listed price. However, this is a premium product and you get what you pay for.

      The W9 is a piece of junk. the sound is ok.....but


      This device is poorly engineered. The sound is ok but the software and phone app is really junk, primitive in design and very user unfriendly. My internet signal is strong and steady, the router relatively new but no matter, the device often drops wifi. And now it won't even turn on. Support is useless. Try calling. For an audio company their support audio is pathetic. Don't buy this product. Do yourself a favor. Save your money.

      Excellent Speaker

      • Verified PurchaserVerified Purchase
      • My Best Buy® Elite MemberElite Member

      It is very hard for me to give 5 stars,buy this is pretty close. Although I own Sonos and Bose, this one is in a class by itself. Sonos is functional, and the highs and lows are great. Bose bass always rocks,but slightly distorts at higher ranges. DT rocks the his and los,and has a decent bass. Although quite expensive;which may prevent many from purchasing. If it ever goes on sale though, grab one. You will not be disappointed.
