At 13mm x 18mm, this new 'sugar cube' loudspeaker is larger than the speaker previously known from ESU. As the diaphragm is therefore a good 40% larger, it can produce significantly higher sound pressure levels. Bass, midrange, and treble reproduction are flawless. This speaker can be used anywhere our bass reflex speakers don't have space, but where the best possible bass reproduction is still important. The same applies to our new speaker: the larger the sound chamber, the better the sound. We supply 4 sound chambers of different heights in the set. With the speaker mounted (hermetically sealed!), the total height is 17.5mm, 12.5mm, 9.5mm or 7.5mm.
