Notes

Abit also included some excellent cables with the Home Theater SP-50. They use thick 18-gauge wire terminated by either an RCA adapter or tinned bare wire. Stenciled on the wire is the brand name Cybersonic. All connectivity options are covered with the included cables, so you are ready to go right out of the box.

The cables

Egad, the dreaded multiheaded snake!

One thing that these specifications show is the relative lack of power. With 85 watts of total power, the Abit's arrived with slightly muted expectations when all channels are driven simultaneously. That is until I plugged them in with the volume control inadvertently set at 50%. These 85 watts of power go a long way.

I had no trouble filling my room with excessive sound pressure. I was also surprised by the relative lack of distortion at these high volumes. The satellite drivers did not seem to be working very hard at these volumes, as I could see very little driver movement. This is in part to the high crossover point used by these satellites. There is a compromise that comes with this, as we shall see.

Mmm... eggy goodness.

The frequency response numbers are once again displayed with decibel boundaries and thus are not very informative. Almost any speaker driver can reproduce sounds within the spectrum of human auditory sensitivity, but some frequencies will be much louder than others. An example of good specifications would list a frequency range along with a decibel range of ± 3dB or ± 6dB.
