This little beast of a bass driver is capable of 18.5 mm linear excursion. You have to hear to believe how much punchy bass it can generate from a 2.8 L volume.

Walk around the speakers and you still get it all: Our miniature ambient tweeter features an excellent off-axis response.

For this reason, the W5 has an excellent polar diagram – which is crucial for breathtaking sound staging capabilities.
