The speakers WTCB552HS from the company TRF Characterized as bookshelf speakers because they are placed on a shelf or special base, which is sold separately. In this category usually belong the main speakers of a sound system, but due to their small size they can also be used as peripherals for better sound simulation. The power of them is 80W RMS, which means they can be connected to an amplifier of equivalent power. However, you should also check the impedance of the speakers and the amplifier to ensure compatibility between them.
