Krix Seismix 3, Seismix 5 Positioning, Trouble shooting, Warranty, Volume, Low Pass Hz control

Volume

The volume control will adjust the volume of the subwoofer only. The control can be set for the subtleties of the lower octaves in musical performances or increased for the earth shattering explosions and effects on movie sound tracks. The volume control on your main amplifier / AV receiver controls volume for your overall system (see figure 1).

positioning

The procedure for setting up any subwoofer can be time consuming, requiring numerous minor adjustments to get the desired result.

There is no definitive 'correct' way to set up a subwoofer. Given different listening environments different people’s tastes and different speakers, there are a number of variables that have to be taken into consideration.

It is up to the individual listener to adjust the Seismix for the character and strength of bass that is preferred for whatever type of source material is being reproduced.

It is beneficial to select music that is familiar to you when carrying out listening tests and setting up procedures and as a suggestion play recordings that use wooden instruments such as acoustic guitars, oboes, cello etc. These instruments exhibit a strong resonant characteristic in the low to mid bass region and will highlight unpleasant ‘woody’ or ‘chesty’ sound qualities suggesting there is too much overlap in the bass information between the subwoofer and main speakers.

To fine tune the integration of the Seismix into your Hi-fi system, start with both the Low Pass (Hz) and Volume at the middle setting. Gradually adjust the setting of the Low Pass (Hz) either up or down (see figure 1). This will vary the amount of overlap from the sub to the main speakers and increase or decrease the level at those frequencies. The effect is a strengthening or weakening of the upper bass region. You might reach a point where the sound develops a 'boxy' or 'chesty' quality which is not desirable. This could indicate there is too much overlap from the sub to the main speakers and is remedied by turning the Low Pass (Hz) back. Adjust the Volume level to suit your personal taste.
