S Dime 420 Posted June 14, 2011 Report Share Posted June 14, 2011 how do you figure out the displacement of your subs and how do you tune a box with aeros? can you do it with torres? if so, how do you do it? Quote If anybody in the Sacramento area has a vehicle for sale for less than $1,500 get at me. I'm open to almost anything that runs. Link to comment Share on other sites More sharing options...
Blazer Boy280 Posted June 14, 2011 Report Share Posted June 14, 2011 thanks for making this topic cuz i would like to know also as i have no clue Quote My Build:Blazer Got Bass Link to comment Share on other sites More sharing options...
JEMT8 Posted June 14, 2011 Report Share Posted June 14, 2011 Check the manufacturer website and it should be listed in the T/s parameters. And yes you can choose between slot port or round ports. Quote formerly known as Jaylor Swift Link to comment Share on other sites More sharing options...
rickyfromthe407 Posted June 14, 2011 Report Share Posted June 14, 2011 I would refer to owners manual for sub displacement..if you do not have the owners manual I am sure it is on the manufactures website or you can directly email them and they will send it to you. Or You could provide us w/ precise model of your subs and we could look into it for you.

PandorasCustoms Posted June 14, 2011 Report Share Posted June 14, 2011 (edited) Displacement of a sub-woofer can be pretty closely estimated by calculating the volume of a "Frustum".... Getting into the tuning frequency gets slightly more complicated. But, I do think Torres's calculator accounts for all of that. I have never used it personally, but I know many others have.

iKidwell Posted June 14, 2011 Report Share Posted June 14, 2011 Yes you can do it with Torres, every company I know of has the displacement amounts of every one of their woofers..its common sense Quote c'mon now, if i was shooting an 8 year old, it wouldnt be MY 8 year old. i recently got a Pyle PL1590BL and i was building an enclosure for it tuned to 25 hz. i didn't have any tools to cut a circle so i hit it with a big hammer. 2003 Infiniti G35 Sport Sedan Build in Progress Link to comment Share on other sites More sharing options...
Torres Posted June 14, 2011 Report Share Posted June 14, 2011 site manufacturers usually have the displacements of their subs on their site. and yes you can use my calculator to tune with aero ports. it's the # of aero ports along with the diameter and length the height and width boxes stay empty as they're for slot ports Quote Link to comment Share on other sites More sharing options...
Blazer Boy280 Posted June 14, 2011 Report Share Posted June 14, 2011 so to calculate displacement frm a sub its different every time depends on the sub and manufacturer how about box rise is there just a single equation to do that Quote My Build:Blazer Got Bass Link to comment Share on other sites More sharing options...
ChevyBoy95 Posted June 14, 2011 Report Share Posted June 14, 2011 so to calculate displacement frm a sub its different every time depends on the sub and manufacturer how about box rise is there just a single equation to do that most subs are different, but are generally around the same amount. REFER TO MANUFACTURER FOR PRECISE INFO ON SUB DISPLACEMENT.

Torres Posted June 14, 2011 Report Share Posted June 14, 2011 (edited) for box rise: you need an AC clamp meter and a dmm. You will need to measure the AC voltage output going to each of your subs or if they're bridged just the wires going into the amp. Once you get the AC voltage you will need to find the AC current. You do this by clamping the negative wire going to the set of speakers. I'll give you an example. You clamp your wire and get 38.6 amps of current You probe the + & - wires and get 61.7 volts Next you would take the 61.7 volts and multiply the 38.6 by it to find your MAX power which would be 2381 watts Next to find out your impedence rise you would divide the voltage 61.7 by the amperage 38.6 which would be 1.59 ohms So if you were to have a nominal or starting resistance of .5 ohms you would have a rise of 1.09 ohms, but would have an overall reactive load of 1.59 ohms forget who i copied that from, but i have it saved on my PC Edited June 14, 2011 by Torres Quote Link to comment Share on other sites More sharing options...
