Agreed, the music from the original british dubstep scene had a lot more in common with dub music than what became popular dubstep. It was mostly heavy bass ran through a low pass filter with the frequency cutoff set up to an oscillator giving it that wobbly wubbing sound.

Dub music itself was actually more popular with the british audience than jamaican audience. Producers like Mad Professor and Scientist and even King Tubby made their dub records specifically to release in England.
