3)Satellite Left-Right Phase Reversal

If the right satellite is reversed in phase from the connections on the left satellite, you will hear reduced bass and a “phasey” dif- fused vocal image. If you suspect the sound is not right and you cannot see any mark- ings on the wire, try this simple test:

1.Stand half way between the two satellite speakers.

2.Play some vocal music with the amplifier or radio set to Mono.

3.Listen to the apparent placement of the vocals.

4.Turn off the amplifier and reverse one of the connections on the subwoofer.

5.Repeat the listening test with the same setting of the volume control. When the sound has a richer bass, is slightly louder and the vocal image is “focused” the satellites are working together or “in-phase”.

Congratulations

A concealed PSW800 subwoofer installa- tion frees you to use your tone controls, play the system loudly and enjoy deep extended bass, even if your satellite speak- ers are small. When used with satellite speakers that have substantial bass of their own, the PSW800 tightens the deep tones and augments the bass musically.

Listening at Higher Volumes

It requires more power to achieve a reason- able volume of sound in a large room than it does in a small room. It is possible (even if you are not a teenager) to turn the vol- ume so high that the amplifier runs out of power. This creates “clipping” distortion. If you are using an extremely powerful ampli- fier it may be possible to hear clicking or buzzing sounds from the subwoofer as it tries to reproduce too loud a sound. If you hear these sounds turn the volume down.

More typically you will hear clipping dis- tortion through your satellite speakers. Clipping distortion makes treble sound very harsh and unmusical. When you hear harsh sounding treble from any good speaker,

turn the volume down immediately! Those harsh sounds are masking some much more powerful ultra-high-frequency sound spikes which will quickly damage any fine loudspeaker. You are much less likely to damage a speaker with a large amplifier because it will be very loud indeed before it produces any clipping distortion.

Cleaning

You can clean the speaker with a damp- ened soft cloth or paper towel. If the speak- er is mounted high up on the wall, use a broom to gently brush it off.
