Bookshelf Speakers — HECO BellaDonna

Inside there are low-frequency speakers with a 20mm kraft paper diffuser and a 30mm sound coil. The wires in the coil are aluminum with a copper layer. The basslines are complemented by a 30 mm silk tweeter. The connector in the housing allows you to increase the RF frequency by 2 dB, which has a positive effect on the sound in remote rooms.
