I have an LDS 1x12 1x6 cab. The crossover is at 1.6kHz, which is the lowest high pass filter Eminence makes. I actually thought the speaker was broken because I could not hear anything from it. It just turns out that you don't get much from it until you are way up the neck. Since the Eminence crossovers are cheap (< $50), I thought I might try changing the crossover. Could I take a 2-way crossover, say the Eminence pxb2-500, and just use the high pass filter? Or will I get noise if the low pass filter is unused? Or, does anybody know of another source of good crossovers < $50? I would like a 500Hz high pass but up to 800Hz would be ok. The speaker in question is the LA6-CBMR.
