There are no studio speakers. Sonically they are fully in order. Have a turntable connected with built-in preamp and sounds satisfactorily. The price-performance ratio so very good. (The power plug, incidentally, was not retrofitted - how to complain some previous speakers had). The "Installation" is very simple and can be performed by any layman. Cable are all in. The workmanship is good. Although it is built a lot of plastic, but the boxes have a good weight.
