Excellent speaker set from Jamo made in Denmark. These compact Jamo 28 speakers are small, but produce a “great” sound. They fantastically come into their own in any medium-sized room. They can be driven with almost any amplifier. They are in top notch condition and work perfectly. The clothes covers are also in very good condition. Jamo is a Danish brand of the better price range. Because of its compact size, there still is a powerful bass with minimal distortion when playing slightly louder. A really impressive sound for such compact speakers. Connection is possible by means of a loose cable or banana plug cable. The dimensions are: 17.5 cm wide, 27 cm tall, 22 cm deep. When shipped, the speakers will be sent firmly and professionally with track and trace by insured mail.
