AA98hoe Posted January 5, 2011 Report Share Posted January 5, 2011 (edited) I noticed my baffle flexes under high output and low freq bass. I bought a 2" circle wooden dowel and was going to put it directly in the middle of my box. question is, thats going to be inline with the middle of my port also. will this cause any disruption in the airflow going in the port? Is the brace worth it? I dont want my numbers to go down, but im curious to see if they go up. any advice will help thanks my box and the dowel Edited January 5, 2011 by dc98hoe Quote TEAM DC AUDIO VEHICLE:98 chevy tahoe 2wd 3-4 drop HEADUNIT:alpine 9886 PREAMP:arcaudio FRONT STAGE:4-6 1/2s selinium,DD component set and 4-selinium tweeters in each door KICKPANELS:jl audio 5 1/4 REAR DOORS: dd components 6 1/2s HIGHS AMPS:zapco 750.2 on front doors,zapco an another 750.2 on kicks and rear doors SUBS:4-ascendant audio 18s with 5 spiders in a custom box built by KINGSUV SUB AMP: 2-dc7.5s ALTERNATORS: 3-mechmans 1- 425comp, 1-smd spec350, 1-270 with adj voltage harness on custom dc bracket WIRE:10-runs 0g front to back BATTERIES:6-d1400s TL results:157.1 at 38hz and 156.8 at headrest score @37hz.

Namosh Posted January 5, 2011 Report Share Posted January 5, 2011 A round dowel will have minimal effect on air flow. Stopping the flex would be worth it. ....and damn! That's a big dowel rod! Quote My Ram Quad Cab Blow-through Link to comment Share on other sites More sharing options...

SPL2K Posted January 5, 2011 Report Share Posted January 5, 2011 Sometimes a flexing baffle actually enforces the bass instead of being a loss. Especially on really low frequencies. Also if its really flexing that bad, just toe nailing and gluing the dowel at the bottom, it will eventually break loose. But no, it wont affect airflow unless its really close to the port.

skittlesRgood Posted January 5, 2011 Report Share Posted January 5, 2011 a brace will mess up airflow a little. the thicker it is, the worse it will be. however, taking away flex in the box should gain. so maybe you lose .3 from a brace but you gain 1db from less flex. it will be worth it. good luck making the joint strong though. see if you can use a jack or something to bend the box slightly. then you can slide the dowel in with some wood glue on it, then use your nails. there is going to be a lot of force on that dowel.
