It has a strong and clear sound. The two full-range speakers have large excursions and provide natural, shallow but perceptible bass, where it exists in the program, without coloring the lows and low-mids as other speakers do, which even use passive radiators. It reproduces voices naturally and leaves air between the instruments. You can clearly distinguish individual instruments and tones in the voices, unlike many others. Depending on the source, it may exhibit sibilance or sound slightly rough. If compared to the top-of-the-line Marshall Willen (which is four times more expensive), it will certainly be beaten but it will survive... Take some time to find the suitable placement for the space because it significantly affects the performance, giving substance and volume to the lows. However, it has excellent tonal accuracy for its size, which shows that the Greek engineers at Crystal Audio are not joking (see also the CASB-240 soundbar), and justifies the fact that the TUB speaker, although lacking buttons for direct adjustment (such as volume, pause, next, previous), in practice, given the proportions, PLAYS MUSIC with dignity!
