Gold Member Username: InsearchofbassPost Number: 5562 Registered: Jun-04 | 5.79 cubic feet without the ports and subs assuming those are external measurements |
Gold Member Username: InsearchofbassPost Number: 5563 Registered: Jun-04 | and divider |
Gold Member Username: InsearchofbassPost Number: 5564 Registered: Jun-04 | minus .1379 for the divider minus .0756 for port 1 minus .0756 for port 2 = 5.5009 cubic feet net without the sub port tune coming up |
Gold Member Username: InsearchofbassPost Number: 5565 Registered: Jun-04 | 46.95 hz port tune without subs |
Gold Member Username: InsearchofbassPost Number: 5567 Registered: Jun-04 | opps didnt see the 17.75 tall only did 17 tall |
Gold Member Username: InsearchofbassPost Number: 5568 Registered: Jun-04 | There this is right 6.07 cubic feet without ports or subs minus .1445 for divider minus .07934 for port 1 minus .07934 for port 2 = 5.766 cubic feet net without sub 41.5 hz port tune |
Gold Member Username: InsearchofbassPost Number: 5569 Registered: Jun-04 | crap i messed up again need to give my brain a break |
Gold Member Username: InsearchofbassPost Number: 5570 Registered: Jun-04 | There this is right ...I corrected it 6.07 cubic feet without ports or subs minus .1445 for divider minus .07934 for port 1 port wall minus .2001 for the port internal minus .07934 for port 2 port wall minus .2001 for the port internal = 5.3662 cubic feet net without sub 43.02 hz port tune |
Silver Member Username: Timothy_314Post Number: 312 Registered: May-06 | hmm... do you think i could add or do some thing to it that would make the tuning like 38 or a lil lower? do you think that box will do fine with the type ares i got? |
Gold Member Username: InsearchofbassPost Number: 5578 Registered: Jun-04 | lemme calculate for you...ill be a few minutes |
Gold Member Username: InsearchofbassPost Number: 5579 Registered: Jun-04 | the above tuning was wrong I forgot you had a higher port than 17 inches your at like a 44 hz port tune....ill see what I can come up with brb |
Gold Member Username: InsearchofbassPost Number: 5581 Registered: Jun-04 | the above tuning was wrong I forgot you had a higher port your at like a 44 hz port tune....ill see what I can come up with brb |
Gold Member Username: InsearchofbassPost Number: 5582 Registered: Jun-04 | .1322 for port wall #1 .1322 for port wall #2 .3967 for port #1 internal .3967 for port #2 internal 4.30 cubic feet net without sub and batting (which increases volume of space sub sees lowering port tune also) 20.25 long port length including the front wall 2.25 wide 16.25 high internal 38.3 hz tune with two pounds of poly batting is the best I can come up with right now but youll be better off going longer on the port but youll lose room in the box ...a 36 hz tune would be ideal....my brain is spent for the day maybe someone else can help heres the program I used http://www.carstereo.com/help2/Articles.cfm?id=31 |
Gold Member Username: InsearchofbassPost Number: 5583 Registered: Jun-04 | scratch what I wrote i messed up you might be ok now brb |
Gold Member Username: InsearchofbassPost Number: 5584 Registered: Jun-04 | .1375 for port wall #1 .13.75 for port wall #2 .3667 for port #1 internal .3667 forport #2 internal 5.06 cubic feet net without subwoofer youll be at a 35 to 36 hz tune with 2 pounds poly batting 38.43 hz without it 20.25 inch long port including front wall of .75 inches 16.25 high internal by 2.25 inches wide internal |
Gold Member Username: InsearchofbassPost Number: 5585 Registered: Jun-04 | up above is correct and a final lol |
Gold Member Username: InsearchofbassPost Number: 5586 Registered: Jun-04 | poly batting was 2 pounds for each chamber.....its poly in sheet form |
Gold Member Username: InsearchofbassPost Number: 5587 Registered: Jun-04 | your gonna have 2.50 inches of clearance from the back wall so your stuck dont use poly batting |
Gold Member Username: InsearchofbassPost Number: 5588 Registered: Jun-04 | add 2 inches to your box depth and youll be at a 35 to 36 hz port tune |
Gold Member Username: InsearchofbassPost Number: 5589 Registered: Jun-04 | i messed up again lol....i forgot to subtract the center divider brb with the correction |
Gold Member Username: InsearchofbassPost Number: 5590 Registered: Jun-04 | This is definately correct 6.07259 cubic feet without subtracting ports divider or subwoofer .1551 for center divider .1375 for port wall #1 .1375 for port wall #2 .3667 for port #1 internal .3667 forport #2 internal 4.90909 cubic feet net without subwoofer .59244 cubic feet added if the box is made 2 inches deeper 5.50153 net cubic feet without subwoofer aprox. .14 off for both subwoofers displacement 5.36153 cubic feet net 37.34 hz port tune with a total of 20.25 inch long ports .75 front board thickness included (19.50 deep before that is added in) 20.25 inch long port including front wall of .75 inches 16.25 high internal by 2.25 inches wide internal |
Gold Member Username: InsearchofbassPost Number: 5591 Registered: Jun-04 | "20.25 inch long port including front wall of .75 inches 16.25 high internal by 2.25 inches wide internal" should read .... 20.25 inch long (ports) including front wall of .75 inches 16.25 high internal by 2.25 inches wide internal |
Gold Member Username: InsearchofbassPost Number: 5592 Registered: Jun-04 | your fine for the 2000 watts rms should you choose to use that much power ...port volocity wise...meaning 73.125 square inches of port area will give great air flow |
Gold Member Username: InsearchofbassPost Number: 5594 Registered: Jun-04 | dont forget to add 2 inches to your depth....from 22 inches to 24 inches |
Gold Member Username: InsearchofbassPost Number: 5595 Registered: Jun-04 | and .25 to your port width from 2.00 inches to 2.25 inches |
Silver Member Username: Timothy_314Post Number: 313 Registered: May-06 | thanks for all that help but im kinda cunfused now...lol :-/ i might just do this box like what some one showed me http://www.subwoofertools.com/forum/ported-box.asp?Ew=32&Eh=16.5&Dia=6&Xmax=22&V d=.14&NumW=2&Vb=4.2&Fb=36&Qts=&Vas=&Fs=&CE=0 If my box is Tuned to 40 Hz will it be ok to put the sub sonic filter to 30 Hz cause it sounds better the lower you put it? and what should i put my low pass filter at? because its louder the higher i put it |
Gold Member Username: InsearchofbassPost Number: 5613 Registered: Jun-04 | Hope this clears it all up ok first heres what you gave 33 wide by 22 deep by 17.75 high I took those to mean measurements on the outside of the box then I changed your box demensions externally to 33 wide by 24 deep by 17.75 high so if use the measurements inside the box you would get 5.36153 cubic feet net and net means actual useable space after all wood and speakers are placed inside the box then instead of a 2 inch wide port I changed it to 2.25 inches wide by 16.25 inches high for proper port function airflow wise then that changed your port lengths (both of them) to 20.5 inches deep and gave you a port tune of 37.34 hz so heres how you build it 33 inches wide (external measurements) by 24 inches deep (external measurements0 by 17.75 high (external measurements) then add the ports like in your drawing but change the scetch to 2.25 inches wide each port and make the height the same as your scetch but to make the port change your scetch from 11.25 inches total length to 20.5 inches total length as far as a box tuned to 40 hz they will sound like crap music wise dont do it....and if your box sounds better with the subsonic set lower than 39 hz on a 40 hz port tune then you probably dont have a 40hz port tune.....and by the way playing lower than your port tune can damage your subwoofer |
Silver Member Username: Timothy_314Post Number: 314 Registered: May-06 | my scetch is a box i got from a friend, will you think that 2.25" will be good SQL for them subs? i really don't like the sound of the box i got now i just want some thing that hits hard and has good SQ and that will be pretty low hitin bass cause im not really likin this 40 hz right now... :-\ do you think them plans from that web site i showed above will be what i want? and thank you for helpin me, Your the only one lol :-] |
Gold Member Username: InsearchofbassPost Number: 5671 Registered: Jun-04 | make a box the way I told you is all i can say....i didnt realize that box was already built.....making your port wider will raise the tune if thats all you do to the prebuilt box |
