The speakers are embedded as Rear-speakers for a 7.1 system in the wall. The wall itself is white, so this white speakers hardly noticeable. After the calibration process by the receiver (Onkyo TX-SR308) the whole system sounds very harmonious and well. The crossover frequency to the subwoofer has been calibrated and adjusted by the receiver to 50Hz. So to sum it very good price / performance ratio.
