remi_357 Posted June 7, 2010 Report Share Posted June 7, 2010 I got 2 kicker cvr 15s in a 4 cubic foot sealed box. (Yes I know, too small but that's all the room I got) I bought 4 pounds poly fill for it and stopped at a pound and a half. It just seems like way too much. The box is almost completly full of fill. Am I doing something wrong? Should I force all 4 pounds in it and throw the subs back in? I'm kinda lost here. Link to comment Share on other sites More sharing options...
BeachJoshua Posted June 7, 2010 Report Share Posted June 7, 2010 fuck wieght, do what you think looks right, then put the sub in, wanna change it, change it up...

ISO Posted June 7, 2010 Report Share Posted June 7, 2010 True but we have adhered to this rule for 20 or so years. I have been running kicker for close to 14 years. Make sure you have your drivers in seperate compartments. If you have 4 cf total then make sure its 2cf sealed per drive with 2 lbs of poly-fill per driver.

ISO Posted June 7, 2010 Report Share Posted June 7, 2010 Odds are you have pounded them way too hard. Take them out and with your fingers push the cone in and out and for issues with your spiders and look for tares in the spiders. Also power them up free air with music to listen to the spiders and listen for a POP sound that will come from the spider.

remi_357 Posted June 7, 2010 Author Report Share Posted June 7, 2010 They are in the same chamber, is it critical that they are seperated? Link to comment Share on other sites More sharing options...
ISO Posted June 7, 2010 Report Share Posted June 7, 2010 Make sure your box is not ripping apart and that no air leaks have developed.

ISO Posted June 7, 2010 Report Share Posted June 7, 2010 They are in the same chamber, is it critical that they are seperated? When sealed yes. EDIT: My opinion.

bkolfo4 Posted June 7, 2010 Report Share Posted June 7, 2010 They are in the same chamber, is it critical that they are seperated? Nope. One chamber is fine Current system: 1997 Blazer - (4) Customer Fi NEO subs with (8) American Bass Elite 2800.1s Previous systems: 2000 Suburban - (4) BTL 15's and (4) IA 40.1's = 157.7 dB at 37 Hz. 1992 Astro Van - (6) BTL 15's and (6) IA 40.1's = 159.7 dB at 43 Hz.

STEvil Posted June 9, 2010 Report Share Posted June 9, 2010 common chamber is fine as long as one doesnt die and they inside is relatively "square" so the drivers will load mostly evenly... When you put the fill in make sure not to let it cover the rear of the woofer or you could be adding extra heat to the coil due to poor venting. Fill shouldnt be packed in extremely tight but make sure it takes up airspace pretty good as the end effect it is having is making the airspace "stiffer".

Any time you have have a power wire next to your frame put some rubber hosing (or cut up an innertube) around it. The wire is bound to wiggle (due to driving or flex) and the casing will eventually wear through. Hammerdown... 1% no links to outside websites, business related FB/YT pages allowed.
