vandersteen 2w subwoofer

I hope someone more tech-savvy than I am can shed some light: would it be possible to replace the proprietary x-2 crossover with a high-pass filter generated by the parametric EQ of a DSP engine? I tried to roll-over 6db/octave at around 80Hz, and it seems to work -- but I don't know if that could potentially damage the subwoofer.
Thank you in advance,
Roberto

Also, I"m not sure what your preamp is. The Parasound P5 and P7 have integrated bass management. That's how I roll. 

Best,

The Vandie subs don't care how you achieve the high pass as long as the main amps are crossed at 80hz.

Thank you both! I am using Benchmark DAC2 HGC as preamp (no bass management); DSP is done through Roon (as far as I understand, EQ is applied to a digital signal). I will go ahead with DSP then, since I believe there is something wrong with my X-2 crossovers.

Just remember that the plate amp in the 2Wq has a build in first order boost from 80Hz on down, so for best results you should feed the mains with a first order roll off from 80 Hz on down.  FWIW, Aesthetix makes some amps that have built in crossovers that are intended to work well with the Vandy subs.
