Summing Sides, Active Filter

hernanstafe · 15th March 2007, 11:20 PM

I'm working in a subwofer and i was wondering if anyone had the schematics and pcb for a sub preamp/filter which sums up both channels cause i've looked for it and i can't find it! I found some on the site but some of the people there say they don't really work, does anyone has one that actually works?!

Figure 1 - Input Mixer and Phase Switch is what I think you need. Its working for me in the lounge with the Transform and I have a 24 db(12 variable 12 fixed),lowpass inbetween the two. My amp doesn't have the muscle though
