Gold Member Username: InsearchofbassPost Number: 1463 Registered: Jun-04 | did you double check those measurements? |
Gold Member Username: SubfanaticWalton, Ky Post Number: 2634 Registered: Dec-04 | haha, yea i just did, they fit alright, with about .5 inches on each side, hopefully i can get my sideways screwdriver in there. This is going to be one heck of a project, but i have to wait for my next shipment of wood to do it |
Gold Member Username: InsearchofbassPost Number: 1467 Registered: Jun-04 | measure the clearance for that too while your at it lol |
Gold Member Username: InsearchofbassPost Number: 1468 Registered: Jun-04 | can you say pre drill boys and girls lol.......with that clearance |
Gold Member Username: SubfanaticWalton, Ky Post Number: 2640 Registered: Dec-04 | what do u mean the clearance |
Gold Member Username: InsearchofbassPost Number: 1470 Registered: Jun-04 | i just ran a box for someone on here with the eclipse 12's sw6123.4 its sweet spots are the 50 hz thro 65 hz range with a 34 hz port tune he should hit his resonant frequency somewhere in there most cars do |
Gold Member Username: InsearchofbassPost Number: 1471 Registered: Jun-04 | whether the angled screw driver you have will be able to fit in .50 clearance....that box for the eclipses (the 6123.4) i ran will be 1.80 cf per sub before the dropping the sub in |
Gold Member Username: SubfanaticWalton, Ky Post Number: 2644 Registered: Dec-04 | ill predrill out ofthe car, assemble it, make sure its nice, then take it apart and redo it in my car, and there will be enough cleareance of the screq driver i believbe |
Gold Member Username: InsearchofbassPost Number: 1472 Registered: Jun-04 | sweet....man if we get this to hit 150 im gonna be siked |
Gold Member Username: InsearchofbassPost Number: 1473 Registered: Jun-04 | you did break this sub in right? |
Gold Member Username: SubfanaticWalton, Ky Post Number: 2649 Registered: Dec-04 | yea, its broke in already lol, but i cnat wait either, it will be a few days till i actually get to build this box though, DAM, im excieted as heck |
Gold Member Username: InsearchofbassPost Number: 1474 Registered: Jun-04 | and all this box will be good for is 45 to 48hz and up test tones....you knew that right unless we make the port interchangable |
Gold Member Username: InsearchofbassPost Number: 1475 Registered: Jun-04 | so am i lol |
Gold Member Username: SubfanaticWalton, Ky Post Number: 2651 Registered: Dec-04 | how can we make it interchangalble, but would it not play any other music? |
Gold Member Username: InsearchofbassPost Number: 1476 Registered: Jun-04 | we can make it 8 inches high 3 inches wide by 8.5 deep for 39 hz port tune this would play pretty much any type of music except bass cds but youd have to be carefull with the volume nob...i did this tune with my cousins kicker c comp 12 and it was like i described.......we can go lower if you want but we must be carefull |
Gold Member Username: InsearchofbassPost Number: 1477 Registered: Jun-04 | well just make the ports plate mounted and screw them in and out one for daily one for spl one note wonder |
Gold Member Username: SubfanaticWalton, Ky Post Number: 2657 Registered: Dec-04 | i dont udnerstand |
Gold Member Username: InsearchofbassPost Number: 1478 Registered: Jun-04 | ok you no your spl ports are 8 inches high by 3 inches wide by 5 inches deep right for 45 hz peaked at 48 hz.........ok well you daily port tuned at 39 hz in that same box would be 8 inches high by 3 inches wide by 8.5 inches deep....now picture an internal brace you would screw into with your port plate and whallah or we could do the brace on the outside of the box and it would seal tighter but not look as nice but we have to subtract .75 inches from our port depth to keep the same port tune |
Gold Member Username: InsearchofbassPost Number: 1479 Registered: Jun-04 | in other words the port plate is a square 10 inches high by 5 inches wide with our port fabricated in that square 8 inches high by 3 inches spl....8 inches high 3 inches wide daily.....depths as per ajustment needed |
Gold Member Username: SubfanaticWalton, Ky Post Number: 2659 Registered: Dec-04 | OHH, so basically cut a whole in the box, make it so that the port has like a frame on the outside that i can screw into the box and slide the port for 45 hrtz, then do EXactly the same thing but make the port longer to tune it to 39 hrtz |
Gold Member Username: SubfanaticWalton, Ky Post Number: 2660 Registered: Dec-04 | if that hole is ther, with NO port screwed in for the time, what would it be tuned to with just the hole? |
Gold Member Username: InsearchofbassPost Number: 1480 Registered: Jun-04 | yes but if you weant the absolute best possible seal we would want to mount it externally but mine internally and it keeps a tight seal but were talkin alot more spl here for you |
Gold Member Username: SubfanaticWalton, Ky Post Number: 2662 Registered: Dec-04 | whatdo u mean internally and externally |
Gold Member Username: InsearchofbassPost Number: 1481 Registered: Jun-04 | about 58.3 with just a .75 inch deep port 8 inch high by 3 inch wide |
Gold Member Username: SubfanaticWalton, Ky Post Number: 2665 Registered: Dec-04 | how loud would that get? lol, but im just wondering |
Gold Member Username: InsearchofbassPost Number: 1482 Registered: Jun-04 | internally meaning a frame inside my box to mount the plate flush mount to my box....externally meaning mounting it from the outside of the box |
Gold Member Username: SubfanaticWalton, Ky Post Number: 2666 Registered: Dec-04 | i will do it externally, because i have no way of doing this internally |
Gold Member Username: InsearchofbassPost Number: 1483 Registered: Jun-04 | it would be about a 3 db increase over the 45 hz tune peaked at 48 hz but it depends on what your cars efficiency is at that frequency |
Gold Member Username: InsearchofbassPost Number: 1484 Registered: Jun-04 | yuyou could do it internally you prob arent following me on the idea 100 percent but externally will gauruntee a tighter seal |
Gold Member Username: InsearchofbassPost Number: 1485 Registered: Jun-04 | is there a paint program on windows i wanna draw you my port structure |
Gold Member Username: SubfanaticWalton, Ky Post Number: 2671 Registered: Dec-04 | yea i have paint |
Gold Member Username: InsearchofbassPost Number: 1486 Registered: Jun-04 | i have it but i cant draw........draw me what you think im saying |
Gold Member Username: SubfanaticWalton, Ky Post Number: 2673 Registered: Dec-04 | ![]() |
Gold Member Username: InsearchofbassPost Number: 1487 Registered: Jun-04 | now imagine a wood frame inside the boxes front panel where the sub basket is and imagine a hole externally that was oversized but had a hole 8 inches by 3 inches in it and you screwed into that wood frame thats inside.....whallah flush mount |
Gold Member Username: InsearchofbassPost Number: 1488 Registered: Jun-04 | this is how i did my sealed ported adjustable ported box for my 12s |
Gold Member Username: SubfanaticWalton, Ky Post Number: 2678 Registered: Dec-04 | im confused, that doesnt make sense to me |
Gold Member Username: InsearchofbassPost Number: 1489 Registered: Jun-04 | explain to me what you dont think you understand |
Gold Member Username: SubfanaticWalton, Ky Post Number: 2679 Registered: Dec-04 | that wholle post under my pic |
Gold Member Username: InsearchofbassPost Number: 1490 Registered: Jun-04 | ok your port is 8 by 3 right? you cut a hole say 10 by 5 in your boxes front panel you make a 10 by 5 plate with an 8 by 3 hole that leaves you 2 inches of solid wood to screw into on the plate width and height........now you make another wood ring inside the box thats say 12 by 7 and have it make a lip to give you a mount from the opening thats 10 by 5 |
Gold Member Username: SubfanaticWalton, Ky Post Number: 2681 Registered: Dec-04 | OH, i gotcha, so it would look like this, i think your saying, gimme a sec to do another awesome drawing |

Gold Member Username: InsearchofbassPost Number: 1492 Registered: Jun-04 | cool there you go flush mount.....mine is done with 4 inch pvc porting with various lengths to each individual frequency i did it to do in car tests with my 12s for the most spl and was going to use my digital spl meter to get readings plus i made sealed plates to make the box sealed.....you may want to buy something with metal type treads to screw into with your screws so the holes dont wear out on the box...i didnt do that to mine |
Gold Member Username: SubfanaticWalton, Ky Post Number: 2684 Registered: Dec-04 | http://spl.mecacaraudio.com/index.php?a=rulebook will u check this out and tell me what class ill be in and if i should look into going to these comps when me and u are done with this stuff and get metered and stuff, ALSO, would you suggset doing vented or with the pvc pipe, whats going to be easier |
Gold Member Username: InsearchofbassPost Number: 1493 Registered: Jun-04 | id say do the slot ports no need to buy any pvc that way plus the the cuts will be easier to cut evenly which is important |
