I have Zu Soul speakers and a Zu Undertone sub. I have XLR cables running from my PS Audio Gain Cell DAC/Pre to my Hypex NCore amp. Just to try something different, I’d like to put a high pass filter (maybe at 60 Hz?) before the amp. I’m looking for a simple option but don’t see much with an XLR in/out except expensive active crossovers. Any recommendations would be appreciated! Thanks.

Well passive interconnects filters are never simple (even if they only have a few parts) and doing it balanced is way more complicated.
But anyway the "Cheap & Cheerful" is the wrong forum.
Find a forum where the NCore people hang-out.

OK, thanks!
