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!!
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.

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. |
Adjusting your subs makes the most sense to me, but I do understand what you were hoping to achieve. There's just never a free lunch, and the downside is likely to have more overall negative impact than positive, but in fairness that's an educated guess, not a fact. Every room and situation is different, but I find my subs sounds best 180 out of phase, low pass filter at the lowest setting, and gain set very low so that it's barely audible except on deep bass heavy passages. YMMV, but good luck and enjoy. |
