Using LPF in your Inuke/amps; do you?
I understand receiver crossover is different from LPF on LFE channel. I've read a few posts from the past regarding setting a LPF within the Inuke amps to run parallel to the receiver's crossover; i.e. speskers crossed over @ 80hz, multiple subs with the LPF engaged in the Inuke @ 80hz.
Some say this is beneficial while others say just let the subs play out and don't bother essentially doubling up per say on the "80hz" crossover.
Everytime I try setting the Inuke LPF my measurement chart line goes haywire. So, I just tend to let it be and just use a HPF only for my ported subs. Unless I'm going about it the wrong way???
unless two different types of subs are being run on the subwoofer channel (such as low frequency and MBM units), a single low pass filter in the avr is best.
the original concept was to use sealed mains that have a natural second order rolloff at 80hz.
then electronically, the high pass on them was 2nd order, providing a 4th order high pass overall.
the sub then received a 4th order low pass to match the mains in both output and phase.
(the lfe channel was supposed to pass through with no filtering in order to provide flat response up to 120hz too).
most folks don't follow the plan, so everything is a bit "wild west".
but...if it works, then it works. :-)
Thanks, I'll keep doing what I've been doing; receiver only
