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.

Well, there you have it. It seems I have about a snowball's chance in Hell of getting this idea to sound correct. I think I will let the Nefes play full range and let the subs give a helping hand under 50 Hz or so. My subs have all kinds of adjustments, so I can mess with them and not really worry about the critical integration of 2 different drivers at the 100Hz range. Thank you ALL!! |
This sounds like looking to create a problem where there is none.  Your speakers go down to 26Hz and were designed to work that way — including the drivers that are custom made by Ref 3a — and you wanna cut them at 100Hz?  And why in the world would you want your subs to be working up to 100Hz with near full-range speakers that cost $10k???  This sounds like a potential big step backwards to me, but I guess anything is at least worth trying. |
That is a very different scenario because the speakers were designed to work together as a system. That’s not the same as kludging together different systems with different characteristics. You might get lucky and they’ll work well together. Or you might not be so lucky. |
