Stee-Z Posted September 9, 2011 Report Share Posted September 9, 2011 i have a 9515 DD on an AQ 2200, with big 3 done and XS D3400, i have a 5ft3 box tuned to 30 hz, i had my gain at avout half way the other day, subsonic.. off.. forgot about that on accident, bass boost .. off.. LPF - little less than halfway, when i would turn the gain up a bit it would make like a popping noise.. real nasty, so i am only able to turn it to about halfway The system is definatly not as loud as i expected it as is, i meen it shoock good at this point and was a descent loud yesterday i changed the subsonic to halfway, round 25 hz( my guess), its a lot more clear now, but a lot less loud i just want to know why this thing isnt hitting like it should?im getting frustrated! my friend has a 9512 on a viper 2600, forgot the wattage, and hes running about 100 more watts than me his is very loud and impressive, yet i can't figure out what im doing wrong, any help would be appreciated thanks Quote (4)DD 9918's (2)DC 10k 8 6.5" focals 2 DD SS4 mid amps Audison Bit One processor Jl-cl-rlc line driver iPad in dash Dual Irragi 320a alts 8 batcaps 4000's Second Skin sound deadened Link to comment Share on other sites More sharing options...

Supercharged DCs Posted September 9, 2011 Report Share Posted September 9, 2011 If it's 55sqin of port area, that will be 11sqin per cube since your enclosure is 5 cubes. I'd definitely work on getting a larger port, the more port I added to a DD3515 enclosure, the better (and louder) it sounded. Seemed to like around 17sqin per cube, but that may be different for your situation. Quote Bassless once again.

Ray Posted September 9, 2011 Report Share Posted September 9, 2011 Port is 4x 14.5"?? You should have around 85sqin of vent. Not 55 Hell even up to 95sqin Your chokin it And tune to 36-37 man. No need to tune that sub to 30 Quote 2008 California state record holder 157.2 Bassrace2009 California state record holder 157.0 BassraceRollin 50's 158.7db2009 King of Cali Bassrace2009 USACi score 160.5 @ 42hz Link to comment Share on other sites More sharing options...

Stee-Z Posted September 9, 2011 Author Report Share Posted September 9, 2011 really? i was thinking, and im totally wrong usually.. im trying to learn more that i would be louder with less port, but that culd be wrong, because it seems like itsnot punching hard like that 12.. its not even getting roof flex :/.. and on the torres it says 10.05 per foot for port ?! idk ha.. i am going to be makign a really good box soon, but would that port area and the box make that much of a difference with the loudness? im feeling id be louder with crap subs at the point i am right now Quote (4)DD 9918's (2)DC 10k 8 6.5" focals 2 DD SS4 mid amps Audison Bit One processor Jl-cl-rlc line driver iPad in dash Dual Irragi 320a alts 8 batcaps 4000's Second Skin sound deadened Link to comment Share on other sites More sharing options...
bassrace Posted September 9, 2011 Report Share Posted September 9, 2011 Yes you need to add more port area.... How much depends. You will have to play around with it. Id shoot for 14 at first the go up from there to around 17 max imo.
