Subwoofer positioning correctly
There are active and passive Subwoofer. Particularly, the active tend to offer various setting options, but also in the case of passive, the correct placement of a lot of the tone change:
- Especially important is the placement of your Subwoofer is: Depending on the distance to the wall, the Superposition of the direct sound and the first wall reflection produces a comb filter effect, because of overlap depending on the wavelength, constructive or destructive.
- Play your favorite song and listen to It from the typical listening position in the room with a different Subwoofer distances until you like the sound of it.
Subwoofer setting you should pay attention to
Volume/Level of/volume: This Knob controls the volume of the Subwoofer.
- In small spaces, it comes through so-called "room modes" to roar from the low frequencies in large Parts of the area. Turn the Knob a little bit down.
- You listen primarily to soft music, turn the Knob, however, high, since, the threshold of hearing for basses is significantly higher than for MIDs and highs.
- So that you can experience in your home theater, the "Low Frequency Effects" on the cinema level, you turn up the volume, if necessary. Take but be sure to be considerate of your neighbors, because the bass penetrate very well through walls.
Crossover frequency/(Separation) Frequency: This Knob specifies the cutoff frequency of the low-pass Filter, so the highest frequency that is (emitted almost) at full volume from the Subwoofer.
- Here you have to find your compromise. The higher the cutoff frequency, the radiated more rich Bass. This is especially important if your other speakers are rather small.
- But: Between 80 and a few hundred Hertz can be localized frequencies is always better. Thus, there is a conflict between the Subwoofer can Position a phantom sound source position arise, for example, in old Jazz or Rock'n'Roll records, where the Bass is often clearly on the side and not placed in the center.
Phase/0°/180°: Both the Stereo triangle, as well as the 5.1-speaker placement according to ITU-R BS.775-1 in approximately equal distances between the listener and each loudspeaker, so that all signals at the same time the listener arrives.
- This is in your listening room is not possible, you can adjust the Phase of the Subwoofer so that the signals arrive still in Phase with them.
- This can, for example, with a Kronecker Delta test: The shorter and crisper the pulse sounds, the more accurate the loudspeaker signals are in Phase with them.
Crossover/Filter/Crossover Network: some Lautsprecherssteme you can adjust how steep - so how abruptly the Transition from Low - to midrange speaker.
- In listening tests, has been shown to midrange drivers that there is a gradual Transition from the woofers, a low-pass low-order - in spite of the odd frequency response for the best listening experience.
