Do No Harm ... well the least harm anyway

I want to insert a high pass filter between my preamp and amp (both Benchmark) so I can limit the frequencies going to my full range speakers (Ref 3A Nefes II) to over 100Hz with a 24 db/oct. slope. The 3 possible ways are passive, active, or digitally (A to D then D to A where this is done through software). I am seeking opinions on which method would be the least intrusive to the original signal (ie. best sounding). Thanks for any replies.

+1, @cleeds

Unless your speakers sounds distorted, I would not limit any high or low frequencies. If that’s the case, I would look at the alternate amplification (amplifier) and preamp.

“My reasoning for wanting to do this is to limit cone movement of the 2 full range drivers”
@koestner,

Have you reached out to your speakers manufacturer? They may be able to guide you on running your speakers full range with recommended amplification. A mis-matched amplifier is never going to sound good even with HP/LP filters.
