Rogers Posted October 2, 2009 Report Share Posted October 2, 2009 so generally speaking... what would make a woofer bottom out at high volumes? an enclosure that is too large or an enclosure that is too small? and just to get it out of the way... say that the woofer is being underpowered by atleast 25wrms and no clipping.... and is in a sealed enclosure...

Guest Posted October 2, 2009 Report Share Posted October 2, 2009 well generally a woofer would bottom out if it has too much power thrown to it, too big of an enclosure, and playing under box tuning (doesnt apply to you in this case) how big of a sealed box are you using?

Rogers Posted October 2, 2009 Author Report Share Posted October 2, 2009 well in my case it is my enclosure for 4 re audio rex8's.... the enclosure is somewhere between 1.2-1.5 cubes.... im not really sure since the bottom of the box is a mold of the floor of my truck....the specs on the woofers require .3 to .35cuft per woofer..... the woofers are rated for 175rms each and im giving them around 150ish after impedance rise each.... and they like to bottom out at 30-40hz..... ive put a little over a pound of polyfill in the box to help... and it has to a point....

troy Posted October 3, 2009 Report Share Posted October 3, 2009 try putting something in the box like a block of wood or something ot take up some airspace (about.5cubes) and see if it still does it. this may help if your box is too big. if it doesnt you may have too much power Quote retarded build on the way..... 2000 bagged s10 2 hdc3 15s aq2200 aq4x90 stinger/knu wire optima batteries 220 amp alt fosgate hu/mids and highs Link to comment Share on other sites More sharing options...
Rogers Posted October 3, 2009 Author Report Share Posted October 3, 2009 anyone heard of an underpowered sub bottoming out from too small of a space?

troy Posted October 3, 2009 Report Share Posted October 3, 2009 anyone heard of an underpowered sub bottoming out from too small of a space? nope you dont bottom out from being in a small area. bottoming out happens when the sub has too much excursion caused by either too much power or not enough pressure inside of the box(caused by it being too small) Quote retarded build on the way..... 2000 bagged s10 2 hdc3 15s aq2200 aq4x90 stinger/knu wire optima batteries 220 amp alt fosgate hu/mids and highs Link to comment Share on other sites More sharing options...
Boon Posted October 3, 2009 Report Share Posted October 3, 2009 Polyfill makes the box seem LARGER and will only exacerbate your problem. I would consider trying decreasing the volume of the box, throw some bricks in there temporarily and see if it changes anything. Quote 10.x volts fo' life!

Rogers Posted October 3, 2009 Author Report Share Posted October 3, 2009 i suppose i may have to try that... i just hate the idea of putting a brick in my subwoofer box... dont ask me why... i have no clue... perhaps im just ocd or something...lol Quote http://www.stevemeadedesigns.com/board/topic/79921-rogers-700-dream-car-update-page-17-a-wall/?p=2335774 93 Saturn SC2My system4 SA-15's Walled 2 Cerwin-Vega S2000's 3 Kinetik Hc2000's Dual 200amp alts. you guys done with the peepee touching contest or do I need to end it?

Lowroll Posted October 3, 2009 Report Share Posted October 3, 2009 Im going through the same thing. my box is too big & my surrounds are buckling when they hit real hard on the low notes. So a smaller box is in the works. Poly fill killed the sound of my box completely. & it sounds like you have way too much in there. 1 pound?

kirill007 Posted October 3, 2009 Report Share Posted October 3, 2009 First get all the polyfill out of it, then try to add some volume on the inside, like a brick or a (big) piece of wood.
