Supercharged DCs Posted June 29, 2011 Report Share Posted June 29, 2011 Hey all, need some help figuring out how much space I have in my wall. All are inner dimensions. Baffle will be 2 1/4" so that's why the depth seems on the small side. I suck at geometry, not going to lie. I've tried and failed at figuring out how much space I have... So please, anyone gifted with the ability to do 10th grade geometry, please help... I'm shooting for at least 10cubes after all displacements. I want 180-200sqin of port, and woofer displacement is .52cubes I'd like a tuning of 35hz... So if anyone feels like helping, I'd seriously appreciate it! I have $6.66 left in my paypal if someone want's a little payment for helping out. THANK YOU!!!!! Quote Bassless once again.

JustinWillmon Posted June 29, 2011 Report Share Posted June 29, 2011 Not sure on the geometry as i dont know how to do the different sides, if it were all the same i think you would have figured it out. But your elite design inc tag had me rolling hahah Quote Link to comment Share on other sites More sharing options...
Supercharged DCs Posted June 29, 2011 Author Report Share Posted June 29, 2011 Well I know all one has to do is figure out the area of the trapezoid (top) and the rectangle (bottom) I just can't do it myself. I'm from Louisiana, we don't learn much lol... And I was hoping someone would get a chuckle or two out of that tag Quote Bassless once again.

ABC Posted June 29, 2011 Report Share Posted June 29, 2011 i got 2256.51 for the volume of the trapizoid and 22701 for the retangular box. i dont know how acurat that is but. i didnt divde by 1728 Quote Link to comment Share on other sites More sharing options...
TeamHT Posted June 29, 2011 Report Share Posted June 29, 2011 volume = L * (b1 + (b2 - b1) * h1 / h + b1) * h1 / 2 There are some measurements missing, I can assume...but I would like to be accurate Quote Tell me...does this smell like chloroform to you?

ABC Posted June 29, 2011 Report Share Posted June 29, 2011 its 13.137^3 ft for the rectangle part 1.305^3 ft for the trapazoid 14.443^3 ft all together Quote Link to comment Share on other sites More sharing options...
TeamHT Posted June 29, 2011 Report Share Posted June 29, 2011 Also, can't figure out the volume of a rectangle AND a trapazoid, I think you're thinking of surface area...let me sit down and do some math Quote Tell me...does this smell like chloroform to you?

Supercharged DCs Posted June 29, 2011 Author Report Share Posted June 29, 2011 If that's correct ABC, that'll come out to 14.45cubes before displacement. I'm messing with Torres right now and seems like I can get 10.3cubes after displacement with 192sqin of port and a tuning of 36hz. 18.5sqin per cube of port... Quote Bassless once again.

TeamHT Posted June 29, 2011 Report Share Posted June 29, 2011 6.5" or 6' 1/2"? Quote Tell me...does this smell like chloroform to you? Link to comment Share on other sites More sharing options...
hdorre Posted June 29, 2011 Report Share Posted June 29, 2011 Also, can't figure out the volume of a rectangle AND a trapazoid, I think you're thinking of surface area...let me sit down and do some math You would find the volume of the trapezoid, then add that to the volume of the rectangle. You would enter that net volume into Torres. Subtract bracing and sub displacements. Then, play with the port in the program. Your box net volume may be off like a tenth of a cube because the program automatically adds a baffle iirc Quote On 5/8/2011 at 7:38 PM, Kranny said: On 5/8/2011 at 7:35 PM, 'Maxim' said: It hurts me inside when I read stuff like this and remember you're 15 LMFAO so true Mitsubishi 3000GT (Old Build) Headunit: Pioneer 80PRS Frontstage: (2) McLaren Audio MLT-2 Tweeters & (4) PRV Audio MR Series Neo 6.5" Mids Substage: 4 15" Hybrid Subs - Tantric Motors & Sundown Softies Amps: Banda 2.4D Amp (Tweets), American Bass VFL 350.4 (Mids), and (2) Ampere 3800s Electrical :Singer 260A Alt & JY Power Lithium 2005 Chevy Colorado Ext Cab Headunit: Pioneer 80PRS Frontstage: 4 PRV 700Ti Tweets & 6 10" Delta Mids on 3000wrms Substage: 6 Fi BTL 18s in a 4th Order Walkthrough on 3 Wolfram 4500s Electrical: Singer "390" and JY Power My Official Feedback Thread Link to comment Share on other sites More sharing options...
