ranio Posted November 8, 2011 Report Share Posted November 8, 2011 Hi guys, Its time for a new box so I'm here lookin for your valued input. I have 2 Option Audio xtms, and an EBII falcon. my current box is tuned to 33hz with 5.6cube gross. 59.80 in² of port area and 19.5inch2 of port area per cubic foot. its a miniwall setup (dodgy sealed) but I want to go back to the boot. I'm currently hitting 140.3 at 40hz on about 2.5k pics of how it is now... http://a5.sphotos.ak.fbcdn.net/hphotos-ak-snc7/291782_10150327517059010_580374009_8409779_451957094_n.jpg http://a8.sphotos.ak.fbcdn.net/hphotos-ak-snc7/294700_10150327516379010_580374009_8409775_840676204_n.jpg http://a5.sphotos.ak.fbcdn.net/hphotos-ak-ash4/304098_10150321520669010_580374009_8374250_1987569027_n.jpg http://a6.sphotos.ak.fbcdn.net/hphotos-ak-ash4/302519_10150322808169010_580374009_8380350_1790169892_n.jpg I want to hit higher dbz but want to do it low. boot opening is about 800-850mm wide but can go 1000-1100mm wide aslong as the depth is no bigger than 300-350mm. so, how should i go about it?

ranio Posted November 17, 2011 Author Report Share Posted November 17, 2011 basically I want to move as much air as I can, and shake everything to hell! I can do a 5 cube box easily, 6 if I push it. Quote Link to comment Share on other sites More sharing options...
ainawi Posted November 17, 2011 Report Share Posted November 17, 2011 basically I want to move as much air as I can, and shake everything to hell! I can do a 5 cube box easily, 6 if I push it. u got 5-6 ft3 for two subs... means 2.5- 3 ft3 per sub .. 1st of all if you pushing two subs with single amp then go with a single compartment i.e one port even two similar amps can work great ... about the tuning ... try to input your data in some enclosure design application like WinISD or bass box pro & get the box designed ... its not easy nor that difficult, if you havent done it before. tune the box around 37-40hz & you will stay in middle.... good luck Quote Link to comment Share on other sites More sharing options...
RAD Posted November 21, 2011 Report Share Posted November 21, 2011 (edited) Mate, it's a US forum; the only falcon's these guys see are from the 60's, and Option Audio is an unknown brand. Shoulda asked on MEA! ANYWAYS... First thing i'll tell you, is unfortunately the OA Extreme's are NOT a good sub for playing lows. Their FS is up above 38hz, and the EBP favoured being sealed. Having also built four "low tuned" systems for them, they just don't have the authority down low like other locally available subs: Earthquake DBXi, SoundStream SPLX, Mach5 IXL etc. In three of the four systems, at least one sub has died. But, if you want to still get loud & low with what you have, since the EB Falcon's have a low & flat boot, you can try sub up, port sideways. We did this in a VS Commodore with 10yr old basic RF stuff, worked out well: (IF you can't see the image, add "Riverside Customs Miguel" on facebook.) 2.25-2.5cuft NET per sub is optimal, we tried 2.8cuft NET @ 33hz with one, box was obviously too large because it sounded weak and hollow. EDIT Whoops, you did ask on MEA! My bad. Well, maybe try a series tuned 6th order.... But i don't see 140+ from the boot being a problem. I did a 3cuft box for a kicker L5 on 900w, got 139.8 @ 38hz in a VS, DD 9512 in my BMW 318i with NO fold down seat or ski port, 141.9 from 2400w...
