In this review, we will be comparing Focus 50 and 702 S3, two Floor-standing speakers from Dynaudio and Bowers Wilkins. The main difference between these two speakers is that the Dynaudio Focus 50 is a Powered speaker which means that it has a built-in amplifier inside the speaker body so you don't need an external power amp or an integrated amp whereas the B&W 702 S3 is a Passive speaker so has to be matched with an amplifier to get any sound from it. Let's have a brief look at the main features
of Dynaudio Focus 50 and B&W 702 S3 first before getting into our more
detailed comparison.
In the following sections, we will get into more detail in order to better understand how the Dynaudio Focus 50 and B&W 702 S3 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.
