Mrbass100 Posted May 22, 2012 Report Share Posted May 22, 2012 Hi to everybody on this forum, i have an problem, i am building a subwoofer enclosure and its for 2 pioneer pioneer tsw-3001d4. Pioneer say that they recommend 1.2 cubic feet volume for each sub in a ported box. So i am going to build a enclosure that is a single chamber, due to space issues, so you double the cubic feet volume, so i will need to come up with an design that has 2.4 cubic feet. However do you recommend that cubic feet (1.2) for each sub, most people said to me that 12's need at least 2 cubic feet to get to there dull potential? Also i am looking for low deep thudering sounding bass, that you can hear as well as feel, how much cubic feet do you recommend to me to use. I already have enough room to do 3.0 cubic feet in a box for both subs, but reducing it to 2.4, as pioneer recommend, will it sound better? I am also going to use aero ports that i am going to tune the enclousre to 30HZ, will lower tuning mean a bigger box, will it matter because i don't want to use the ports diameter and length that pioneer recommend in there specs as that is around 33Hz, which i don't want.

Mrbass100 Posted May 23, 2012 Author Report Share Posted May 23, 2012 (edited) Hi thank your for replying, the car is an porchse 968, classic in 1990's and the maximum dimensions i can get is Depth:10 inches Width:37 and height 13.5. I want to create an box that will give me low, deep thumping bass, please can you help me? I suggested myself to use aero ports, as they take less box space up, using 2 2.5 inch ports, tuning box to around 30Hz. I look foward to your reply:) The amplifier is an 2000 watt mono block, provinding 1000 rms to each sub.

grim83 Posted May 23, 2012 Report Share Posted May 23, 2012 the difference between a 30hz tune and a 33hz tune is minute at best as for volume i will let someone with more experience with that sub speak up but i would use a larger diameter aero port Quote team chat assholes ftmfcsw skittlesRgood[/color]' timestamp='1337803095' post='2027302'] go for it. 1st off, you couldnt get past the gate. second, i wouldnt even hear your system inside my house. third, i would just turn mine up and drown out your system, eat my skittles, and laugh at your pathetic ass.

Mrbass100 Posted May 23, 2012 Author Report Share Posted May 23, 2012 (edited) Thank your for your thought, so should i build a 2.4 cubic feet enclosure? Pioneer say that one sub in an individual aero ported box recommend 1.2 cubic feet to work in. However i am very limited to space an can make a box to put both subs in, by creating a dual single chamber box that has a cubic volume of total 2.4, 1.2 for each sub and porting it to 30HZ? Another question is that pioneer recommended 1.2 cubic feet for each sub and say the recommend enclosure volume includes speaker displacement, so i just build a 2.4 cubic box, port it and it should be fine? Or do i need to calucalte speaker displacement myself from 1.2 cubic feet they have stated on the specs sheet?

getlocivic Posted May 23, 2012 Report Share Posted May 23, 2012 you have to account for port and woofer displacement also general rule for slot ports is 12 to 16" per cubic foot ( to get port area all you do is width x height) aeroports work well in the 7 to 11" per cubic foot if you do 2.4 cubes and then stick ports in it will be far to small and sound like ass Quote Link to comment Share on other sites More sharing options...

I look foward to your reply:) The amplifier is an 2000 watt mono block, provinding 1000 rms to each sub. Depth:10 inches Width:37 and height 13.5, if those are external dimensions your gross internal volume is 2.1 cubic feet (not accounting for sub, port displacements). With two 3" 20" long ports you are tuned to 33Hz but you don't really reach the minimum recommendation of 0.8 cubes net per sub. So your alternatives are both sealed or one ported.

Mrbass100 Posted May 23, 2012 Author Report Share Posted May 23, 2012 (edited) Hi thank your for your replies, i have new dimensions, as i didn't measure it properly, as i a was measurng them in the dark lol. So height 14.5, 38 width and depth 10.5, which overall creates in double sub single chamber box = 2.47 cubic feet. So pioneer recommend 1.2 for each sub ported, so i have two subs arond 2.4 cubic feet, so i am ok then? Including sub displacment, as pioneer say 1.2 cubic for sub box, including woofer displacment.
