I would just look into a good Bluetooth speaker like the offerings from Marshall, B&O or the B&W Zeppelin.
Need a easy drive speaker while I am traveling
I love the music so much, if I am going out for travel with my car for a few weeks, I can not stand without the music.so I search a replacement way, the amplifier I can find is Yamaha r-N602 as it is a streamer amplifier and it is the jazz I love on that streamer, then I need to select a pair of speakers. Obviously it will be easy to drive and be best for vocal Jazz. Could anyone here to suggest something to me? Thanks very much.
