rudypoochris Posted January 23, 2009 Share Posted January 23, 2009 So I have been working on a subwoofer for my house! It is powered by a 1024 watt @ 4ohm amp, but it will be running at 1140 watt RMS into a 3.6ohm load. It is 96"x30"x24" and will weigh near 500lbs when complete. The sub should output SPL's continuously over 130db at 1 meter. Holds -3db down to 24hz, according to calculatuions. =] If I could have my cake and eat it too, the box would be 1800 liters which would allow the subwoofer to hold flat down to 22.5hz... within -1db!!!!!!!! Unfortunately reality dictates this box be no larger than 1000 liters or so, so it should hold -1db down to 28hz, or -3db down to 24hz - which is still impressive based on the relatively minimal cost of this project ($750). Unit includes 8 x 10" woofers, 4 x 4" mids, and 4 x 3" tweeters. The sub will also take the place of the center speaker for my 7.1 surround system. The mids and highs have a 300watt cross over set at 4500hz to take care of that end of things. This is definitely a learning process for me and is my first audio project of this kind. Hopefully it does not sound terrible or explode. Worse comes to worse it is an expensive, heavy, and impressive looking paper weight!

Nizm0Zed Posted January 24, 2009 Share Posted January 24, 2009 this is all good and well (and i wish you luck in annoying a 20 mile raduis) but have you considered the structural ramifications to your own house? Quote Link to comment Share on other sites More sharing options...

big-phil Posted January 24, 2009 Share Posted January 24, 2009 If your neighbors are far enough away that would be cool. I have a story:redface: The people across the street years ago had new years party and 4th july party. We live in the county so we can set off fire works. My daughter was a new born at the time and they went all night, I got no sleep because my kid was crying..............8ish years later. They have a baby, I have some loud motorcycles, 4 wheelers, guitar etc... He comes to complain to me about the noise one late evening. I'm keeping his daughter up:icon45: What goes around comes around, just be thoughtful of your neighbors. That being said, it looks like a kick ass sub set-up. I'll take one.

rudypoochris Posted January 25, 2009 Author Share Posted January 25, 2009 Hah!! You got that from the PE forum!! What? I am pretty reasonable with my neighbors. I basically just box my house in and blast AC now. Unfortunately all the smokers have to go out into my atrium to smoke instead of the backyard. No complaints last night and it was LOUD. =] Quote Link to comment Share on other sites More sharing options...
