Silver Member Username: Aman2005Post Number: 141 Registered: May-06 | Hello Shaine, Rovina and SPD, First of all thanks to SPD for specifying my the box dimesnions. I dont have a lot of money to spend on the enclosure. SO I don't want to take the risk. Please upload a diagramatic measurements or a rough sketch specifying the dimensions for a ported enclosure tunes at 32 - 35 hz for my TWO TYPE R's 10". 4 ohm. I was unable to understand the way to make a ported enclosre for the type r. My trunk size is aprrox as follows *deep - 6 to 8 feet, from the trunk opening to the back of rear seat *wide - 5 - 6 feet. from left tail light to right not sure about height, because forgot to measure and its night here can open the trunk, parents'll kill me, its tool late here. anyways, but a sub of 15" can be easily fitted with still some space left. Please draw and upload a rough drawing for the enclosure. I'll be really thankful to you |

Silver Member Username: Aman2005Post Number: 145 Registered: May-06 | well, i couldnt understand that which is width height and depth. Actually when I assume it to be w x h x d, and enter in to the site recomended by steven, the diagram displayed is a weird one |

Silver Member Username: Aman2005Post Number: 146 Registered: May-06 | Rovin thanks for the suggestion. As you said, its a easiest method for a newbie. Anyways, on the Alpine Canada webpage, they suggested a vented box dimensions, I think they are for a single woofer, right? If so, I have a pair, will I have to make two ports? how far should they from the sub woofers?the recomendatio is as follows: Optimum Vented Box External Box Dimensions: 12.5" x 14.5" x 17.25" Gross Internal Volume: 1.3 cu.ft Vent Area (dimensions): 11sq.in. (11" x 1") Vent Length: 22 in. Vent Displacement: .0.237 cu.ft. Net Internal Volume (Vb)**: 1 cu.ft. F3, ripple, Fb: 30Hz, 3.5dB, 36Hz * Based upon 3/4" (19mm) baffle thickness. ** Includes all internal driver and vent displacement, based upon 3/4" (19mm) MDF construction and standard front mounting. ALSO, ON THE 12VOLT PAGE YOU SUGGESTED, THE IMAGE IS SHOWN FOR A RECTANGULAR BOX, WHICH IS THE MOUNTING SURFACE? I MEAN ON WHICH SIDE SHOULD THE WOOFER BE MOUNTED, SO I CAN LOOK FURTHER FOR THE ENCLOSURE DESIGN. Thanks |

Silver Member Username: Aman2005Post Number: 147 Registered: May-06 | Also, when I calculate the internal volume of the rectangular box by doubling the recomended measurements of the ecnlsoure, so I can fit two subs, the resulting figure comes is 12.34158 CU FT. Is that fine?? and when I enter that calculated volume in the port length calculator, the fig was -0.83298 |

Gold Member Username: RovinTrinidad & T... Post Number: 8154 Registered: Jul-05 | have u ever seen my install ? it will give u some ideas https://www.ecoustics.com/electronics/forum/car-audio/189456.html im not familiar with ur trunk space u ur gonna have 2 figure out what will fit even thou 12volts show dimention for 1 box u simply build ur box as its 1 box with a separating bord in the middle , so really its simply as dubling the total lenght but other 2 dimentions remaining the same pvc port should be on same surface side when sub is being mounted & each sub MUST have its own port NOTE - when u input volume notice how the length of pipe required 4 the freq is cause if u build the box too shallow then u will end up in SH!T . When ur port is in leave @ least 2" of space from end of port to back inside wall of box . play around with the calculator till u get the dimentions suitable 4 ur port length/freq & trunk space ... |

Gold Member Username: RovinTrinidad & T... Post Number: 8155 Registered: Jul-05 | AMAN - u have 2 double THE LENGTH ONLY ... Shaine - i have 2 sets of boxes i made which i had from my previous pioneer 306 subs set u see in my install is 1.65cuft which was tuned 34hz - recently modded it slightly & im getting almost same bass output possibly more with each getting only 200wrms (off my 4 chan alpine amp) than when i had my mb quart amp giving it 500wrms each . Will run a thread on that later when i carpet it over & my bro brings his digital cam so dont bug me 4 details as yet -lol !. 2nd box set is 1 box wit 2 chambers , 1.88cuft in each chamber , had it @ 31HZ = seriously deep SQL bass , gonna mod that 1 2day too . With both sets of boxes i often changed out the pipe 2 see which freq i liked best = 33/34hz = nice SQL ... |
