Jagdzaku,
Even if your phono preamp has a LF filter, an arm/cartridge combo with a native resonance of ~5-6Hz is asking for trouble. At a minimum, it would impair clean tracking and overexercise the suspension in the cartridge, possibly shortening its life.
Anyway, most LF filters do not operate as brickwall filters (unlike the HF filter in redbook CD players). SOME of that LF energy is going to make its way past the filter and into the amplification chain. At best, that adds sonic mud and raises your system sound floor. At worst, it may overstress amps or speakers.
Listen to Johnnyb53, he answered well.
