thus creating a membrane that is extremely very light but has a rigidity and non-deformability never seen in any other speaker in the world

In doing this they add both distortion and noise

without the use of the classic dust cover

the exact opposite is true

The RCA signal from a head unit is a very low level signal

Zapco ASP-OEB Mono Amplifier thus creating a membrane thatFor many years people have been using passive LOCs to adapt speaker level signals to RCA signals so they can add amplifiers to their systems. The results have been less than satisfactory. In fact many (if not most) folks out there have come to accept the fact that the factory stereo signals are just not good enough to be adapted into a top quality sound system. But they are wrong! Passive LOCs: There is nothing wrong with the factory stereo signal.
