jhmeg2 Posted August 23, 2013 Report Share Posted August 23, 2013 a cube will have a better chance to generate a standing wave within itself. if it could be deeper and not as wide, or vice versa, also if you were to 45* the internal corners, and round over any edges the air moves accross will help. Also as stated above, is it net or gross? but yeah, on second thought 4.5 is big for a 12". recomended is 1.5.... I mean, a little bigger would be ok, 10" 12" 15" 18" Mounting Depth 6.25" 6.75" 8" 9.5" Mounting Hole Diameter 9.25" 11" 14" 16.75" Outside Driver Diameter 11.0" 12.5" 15.7" 18.5" Motor Width 7.75" 7.75" 7.75" 7.75" Weight 32lbs 33lbs 33.5lbs 36lbs VC Diameter 3" 3" 3" 3" Displacement .16³ ft .18³ ft .21³ ft .26³ ft Magnet Weight 29lbs 29lbs 29lbs 29lbs Power Handling RMS/Peak 1400/2800 1400/2800 1400/2800 1400/2800 Impedance (Ohm) D1 or D2 D1 or D2 D1 or D2 D1 or D2 Sd 324cm² 481cm² 823cm² 1217cm² Vas 12.42 liters 27.38 liters 80.16 liters 175.29 liters Cms .085 mm/N .085 mm/N .085 mm/N .085 mm/N Mms 184.5 g 207.53 g 318.5 g 427.53 g Fs 40.2 Hz 37.9 Hz 30.6 Hz 26.4 Hz BL 19.18 NA 19.18 NA 19.18 NA 19.18 NA Re 3.82 Ohm 3.82 Ohm 3.82 Ohm 3.82 Ohm Le 3.78 mH 3.78 mH 3.78 mH 3.78 mH Qms 7.77 8.24 10.2 11.82 Qes .49 .52 .644 .746 Qts .461 .489 .60 .701 Xmax 23.5 mm 23.5 mm 23.5 mm 23.5 mm Ref SPL @ 1 watt 84 dB 86.4 dB 87.4 dB 88.2 dB Suggested Sealed .75³ ft 1³ ft 2.75³ ft 4³ ft Suggested Ported 1³ ft 1.5³ ft 3.25³ ft 6³ ft ////Alpine, Eclipse, Load Boss, Pheonix Gold, MB Quart,Digital Desings, Memphis, Stinger, Periphial, MTX, Visualogic Link to comment Share on other sites More sharing options...

girlcrazy_4 Posted August 23, 2013 Author Report Share Posted August 23, 2013 a box of 1.5cu/ft seem sooo small... Looks like I've got 3 options. Run a second 12inch sub, switch to a 15inch DC, or a 15inch DD 3500... I'll see what my paycheck brings. Link to comment Share on other sites More sharing options...

john253a Posted August 23, 2013 Report Share Posted August 23, 2013 45's in the port is a good idea But not in the net area Brace the box with dowel rod or all thread And if on 15-1700rms Go with 1.5net 23sq" of port That sub also goes well in a t-line if your not theoughing huge power at it Link to comment Share on other sites More sharing options...

CleanSierra Posted August 23, 2013 Report Share Posted August 23, 2013 Youre getting ZERO cone control in that box, if you've even hooked up your system yet and played it. You are basically free airing your sub in that enclosure. That one 12" will likely not pressurize that airspace very well, if at all. As mentioned, a perfect cube is BAD for enclosures as far as standing waves and funky responses Im not the one you want to try to troll. Just a fyi for you.

SPLadd1ct Posted August 23, 2013 Report Share Posted August 23, 2013 "Is the size of my box too large?".....that's what she said haha....anyways what sub OP? anyways there is a huge difference in gross and net. Your net volume is the actual volume the subwoofer is receiving after all displacements have been accounted for, such as volume of the wood itself, extra baffles, subwoofer, bracing, 45's, speaker wire (jk) and the port. My big ass two 12's box I made is 9 cubes gross but only comes out to 5 cubes net...big difference eh? a 12" subwoofer typically needs 1.5-2.0 cubes but in some cases and depending on your goal, you may require less or more volume, but anyway you look at it 4.5 cubes net is a ton for a 12" and even on the large side for a 15" driver. 2011 Ford Ranger Sport 4.0 v6 2 sundown audio prototype nsv4 15s crossfire 4k wired to 0.4 ohm 15 banks of maxwell 3.0 caps @ 18v triple alts (x2 us alt 250's, x1 singer 320) 153 at 23hz Link to comment Share on other sites More sharing options...
Facekicker Posted August 23, 2013 Report Share Posted August 23, 2013 Im thinking the 4.5cf is including port and no displacement, but it still looks a little big. edit: oh. what he said ^ 2002 Monte Carlo Started a build log Fi, DC, Mechman, XS Power Link to comment Share on other sites More sharing options...
