BJD3 Posted July 18, 2011 Report Share Posted July 18, 2011 Is this just an experience thing? I keep seeing people whom I consider /very/ knowledgeable suggest boxes considerably larger than the manufacturer suggests. I understand larger boxes will play lower, but at what point can you see a box is too big. Obviously, you wouldn't put an average 10" subwoofer in five cubes, but for my level four for example, what would be too much? 2.5? 3? 10? lol. Anti Peel and Seal...lol You may be offended by the above. Don't take it personally, I'm just abrasive. 2002 Buick Park Avenue DC Level 4 M2 12 D2 Car Audio Bargain 1600.1 Eclipse CD3200 ~2 cubes @ 34 hz.

Team_DC-Derrick Posted July 18, 2011 Report Share Posted July 18, 2011 i would generally run recommended box specs from the manufacturer running @ the rms... if running under the rms, then a slightly bigger box would be better running over the rms, smaller than recommended The DC Integra 3 18s to 6 15 build log Team_DC-Derrick's Youtube Team DC Audio where theres a will theres a wall....... I just realized Steve has reach Voldemort status, over on JP's site he is the one who will not be named....."We dont speak his name over here, fearing it will destroy us" LOL not even in hush tones Link to comment Share on other sites More sharing options...

tonedeaf Posted July 18, 2011 Report Share Posted July 18, 2011 It seems to depend on the person building it. Ray likes his boxes big as it drops the f3 of the sub a ton, which helps with the lows whether your box is tuned terribly low or not from my understanding. Fecupe seems like he suggests the same style of box building. These boxes are considerably bigger than the 'average' installer would suggest from what ive seen. Where as others like the box smaller. I trust in both of their opinions as they are doing very well in the audio scene and have been in it for quite a while. Ray has built over 500 boxes and says some subs just like the bigger box. I dont think youd learn these things with just a dozen or so. Link to comment Share on other sites More sharing options...

The man has 2 12" mayhems in a 4.7 CF box AFTER displacement. Sounds huge for 12"s, but hes pulling almost a 156 with them. Link to comment Share on other sites More sharing options...

I have no idea though, every sub is different, every car will react differently on every install..

Exactly why I'm asking. lol And from what I understand, he does it while maintaining more output down low than I do. Anti Peel and Seal...lol You may be offended by the above.

lunchbox.inc Posted July 18, 2011 Report Share Posted July 18, 2011 i've always leant towards bigger boxes than specs, i find most manufacturers recommendations are a nice trade off between decent sound quality, and output, whilst fitting in the smallest space possible... with nearly every box i've built, i've found it better going from the factory specs, to around 10% larger, thats not an exact number, different subs like different boxes etc, but it's a ball park figure so you know what i mean.... however i also tend to lean towards less port area than others, this is just my preference as it seems to offer more control under tuning frequency when done right.... but as stated above, smaller boxes if your running more than rated power, and bigger if your running less is a good rule of thumb....
