I use these speakers for two years.

I love the ease, smoothness, weight, aesthetical.

I do not function or line microphone
j'aurrais have loved to have a xlr line with volume and an XLR microphone with volume.
Able to connect a microphone and make the announcement without having to mute or more connecting a mixer. (Config very convenient for the sound to cocktails)

I did not try other models before, I am very faithful to DAS, and Sennheiser for the quality of customer service

Quality affordable price today knowing that a speaker costs a little less than 900 euros, but in those early days more than 1200 euros.

I would do the same choice.
