Posted June 16, 201015 yr Idk what to tune to for a Home setup. But I have a 4 inch aero port and a Fi X 12 DVC 4 ohm. I was thinking something like 2 cuft tuned around 24 Hz?
June 16, 201015 yr What kind of system is this for? Music, video games, movies?If it's for movies primarily, you may want to tune a little bit lower. A number of movies have some rumbles down in the 16-20 hz range. So not only would you want to pick those up, but most home amps don't have subsonic filters so you'd want to protect the sub a bit with a lower tune as well (though some do have a set ssf). If it's primarily for music, you may want to tune a few hz higher to help with the output in the 30s. That being said, I think my home subs are tuned to 24 hz and I like it and have never had problems .

June 17, 201015 yr Author My next problem is powering it. I was thinkin about using my receiver. but the dual four can only be wired to 2 or 8 ohms. Think it could wire it to 8 ohms and connect two speaker outputs together from my receiver?
June 17, 201015 yr Dual 4 is what you want, you have to build a 2-way passive crossover, or buy this one like this-Subwoofer Crossover 4 Ohm 130 Hz 200W | voice coil subwoofers subwoofer crossover subwoofer subs sub woofers sub woofer sub power dual voice coil Crossovers coils COIL 4 ohm crossover-41108 Crossovers123008 | Parts-Express.comIf you can't put the sub near or between your mains you may need a lower crossover point to help you not localize the sub...You run both voice coils seperately, one off of the left main and right main out of your reciever. The crossover filters everything below the crossover point to your sub (while presenting a 4 ohm per channel load) and everything above the point to your mains (presenting whatever your mains impedance is as a load). Super simple.Before someone says something stupid about this, this is how about a million passive subwoofers have been working for the last 20-30 years... lol....
