Your room settings would have an effect on what you hear from the set of your Philips audio system. Below are some general tips to get the best acoustic effects:
Proper rack for speakers
Choose a proper rack to hold your speakers. Some racks, especially metal ones, add harshness to the sound - the rack vibrates with the speaker and triggers external vibration noise.
Speakers being placed on the floor (especially uncarpeted floor) may also cause external vibration noise. Therefore, placing the speakers on the floor is not recommended unless there is a stand.
It is recommended to have the speakers at the height of your ear level when you sit on the hearing spot.
Location of the speakers
Place your speakers as wide apart as the cable length allows. Increasing the distance between the speakers enlarges the soundstage, allowing you to have more involving sound
Place your speakers slightly away from the wall (no less than a distance of one footstep) to avoid strong booming sound
Angle the speaker upon the hearing position. This increases the solidity of the sound.
If there is a subwoofer in the system, it is suggested to place it in the front part of the soundstage but 8-12 inches (20-30 cm) from the wall. This increases the chance of you sitting in the best spot for bass.
Having speakers or a subwoofer facing the window is a not a good idea as this makes sound rebound difficult in the soundstage
Location of other furniture
Avoid placing other furniture such as tables and chairs between the speakers and the listening position. These obstacles may cause unexpected sound rebound.
Finding the hearing sweet spot
Adjust the location of your chair back and forth to find the best hearing sweet spot
If possible, use a low-backed chair or sofa so that your ears will not be deprived of the acoustic details
