J.Reed Posted April 12, 2011 Report Share Posted April 12, 2011 It is very usefull in spl and sq. The resonant is where it will have a peak or be louder at a certain frequincy. Knowing this you can tune the box to peak here to gain SPL for an SPL ride. Or you can also use this to help maintain a flatter response throughout the sub frequency range. Achieving a more true sub stage for sq. Subs up and port rear it should peak around 44hz 1sy part is correct, second part is not. the car does not resonate differently based on how your subs and port face. that would be like saying the FS of a sub changes depending on how you mount it. Oh yes it most certainly will. Its all about 1/4 wave format. The distance of the wave from peak to peak. If it is a small difference like sub and port rea no not a change really. Set it in the back seat and not in cargo and it WILL change. Im sure if you go from kick to windshield you will see that it peaks a few hz different. This is because of the effect in wave length.

jreese92 Posted April 12, 2011 Report Share Posted April 12, 2011 how can you find out where yur car peaks at Pioneer 6300ub Rockford Prime 6.5's Pioneer 6x9's Alpine MRP-M500 10" Alpine Type R 1.4 Cubic Foot Enclosure Tuned to 34 hz Stinger 4 Gauge Wires Link to comment Share on other sites More sharing options...
bignickk Posted April 12, 2011 Report Share Posted April 12, 2011 If you know where your car peaks at it makes tuning for spl easier but you will sacrifice Sq and deep bass for spl in most cases someone correct me if im wrong. and as for your truck I have no clue. Wrong The magic is in 1/4 wave. Sound wave have peaks and lows. The distance from peak to peak is the key here. distance to mic or ear is what will determine these "peaks". My vehicle peaks at 21.5hz, 43hz and i dont have them after that becuase they are filtered out with the crossover. at 60 hz yea reason its strictly for comps because if ur car peaks at 50 hz. and u tune to 50 hz music will sound like complete dick. and may even damage shit Actually you can use it to have a nice helpfull punch to your music. ADN IT WILL NOT HARM NOTHING. that is complete bull shit. o it dont hurt thats good to know. heard it did....yea i guess like a midbass would be tuned higher. 2000 tahoe orion hcca 15.4 kicker zx2500 2 JL 300/4s infinity and kicker mids/highs KHC1400 in back, stock upfront dont ask about my HU clarion EQ kicker/fosgate rcas Link to comment Share on other sites More sharing options...
TheyDontWantMusic Posted April 12, 2011 Report Share Posted April 12, 2011 Actually you can use it to have a nice helpfull punch to your music. ADN IT WILL NOT HARM NOTHING. that is complete bull shit. well, actually, if your car peaks at 50Hz, and you tune to 50Hz, then a lot of music will have bass below the 50Hz, and happily bottom out your woofers if played too loudly. it may still sound ok at moderate volumes, but crank "Bass From The Krypt" at high volume through your 49Hz tuned box, and enjoy hearing your subs voice coil hitting the subs backplate, from 20 meters away...

If your playing music through a fart box your a RETARD lol. There is a bit of COMON sense to be used here. My vehicle peaks at 43 hz. My enclosure has an FB of 35HZ. guess where it peaks? LOL 43hz. Usually your peak will be 7 -11 hz up from tuning point. Number 2 there is a cool thing called a subsonic filter that should be fixed to or just below FB. Oh let me dumb that down too. FB is resonant of the enclosure other wise know as tune. I may not have 3000 post here but im no noob and DO KNOW what im talking about. Link to comment Share on other sites More sharing options...

I may not have 3000 post here but im no noob and DO KNOW what im talking about. you made reference to a box tuned to the cars frequency as having a nice punch. it can't have a nice punch if you're only playing tones through it. so anyway, you can get away with playing music through an SPL tuned box, if you don't play loudly below the tuning frequency.

Robert8252 Posted April 12, 2011 Report Share Posted April 12, 2011 My peak has been 1hz below box tuning lol. And port area has a huge effect on how much lower you can play under tuning. You could play 20hz under tuning with small enough ports 2013 F150 Crew Cab Old Build Log Feedback 2013 F150 Equipment - Some Awesome Stereo Sound Making Stuff Link to comment Share on other sites More sharing options...
J.Reed Posted April 12, 2011 Report Share Posted April 12, 2011 ^^^^^^ with a huge port and just a farter you bet you can peak at or a bit below tune. Tells me closing port to lower tune may help ya;) I was speaking in general as in more musical aplications. You are also very correct in playing farther below with a small sq.in to net port. EVERYTHING comes down to A CRAP ton of factors Link to comment Share on other sites More sharing options...
AMI CUSTOMS Posted April 12, 2011 Report Share Posted April 12, 2011 Play below tuning with a large enough port and alot of power, you will rip spiders from the former or crack the former, ask me how I know...LOL and J.Reed you are a NOOB,,,OH say something bish!!!!
