A:AnswerThese speakers are 8⅜" H x 5½" W x 3½" D and weigh less than three pounds. Here is a link to a help article that explains how to do the initial setup: http://bit.ly/2mCBTei
A:AnswerI don't know. When I tried to use Wifi it would play one song and stop. I would suggest you call Bose customer service. They are fabulous about helping answer questions. I am just using Bluetooth now.
A:AnswerYou can use a computer to select music or set presets directly on the speaker itself. If you have further questions to ensure that this is the right Bose product for your needs, don't hesitate to give us a call. You can reach us at 1-800-379-2073. We are open from Mon. – Fri., 9 AM – 9 PM EST.
A:AnswerWhile the SoundTouch 10 is not designed to be used as a rear speaker in a surround setup, the SoundTouch 300 system does have the option of rear wireless speakers. Here is a link to check it out: http://bit.ly/2hrzvkP
A:AnswerThere is no mounting screw on the speaker to be able to mount it on the wall. If you have a small shelf that is capable of supporting three lbs then that would be the best way to go.
A:AnswerI don't have the 20, so I can't speak to that, but the bass is mediocre. And the only control you have over the bass via the App is to decrease it, so it doesn't get any better. These speakers rather shine in the mid and high ranges, and produce only adequate bass.
A:AnswerYes, the soundtouch units are superb. Purchase the https://www.bose.com/en_us/products/speakers/wireless_speakers/soundtouch-adapter.html, soundtouch adaptor to make any set of speakers instantly compatiable with the rest of your soundtouch units.
A:AnswerIf you want to play music with them, maybe, but if you want to use them as part of your home theatre for tv/movies/videos, probably not--they don't even work with my Soundtouch 300 soundbar.
