rawlins87 Posted March 4, 2010 Report Share Posted March 4, 2010 So Just thought i'd share some pics of my hobby and what i do for a side job. First off i competed in dB Drag racing and MECA competitions in the past and will be making a return with a huge system for the 2010 season. But here are some smaller builds I have done in the past.Here's the latest box i'm working on. Its 4 Tang Band Neo 8s, on 600wrms. around 3 cubes with 30square inches of port tuned to 30hz. Its a smaller port than i would use but it should keeps the woofers from over excursion and keep even pressure (being that its a weird designs and would have uneven backpressure)O and my 1 8 on 100wrms probably plays lower than everyones 10/12si've built hundreds of boxes, i can post more pics if anyone want to see.Home audio/car audio. If anyone is impressed by a prefab box you wouldnt believe what subs can do if the box is specifically built for the subUsing dowel rods for cutout placementFirst layer of glassTesting sub fit, and starting mud- after 7 layers of glassas of right now the box is done with mud and is primered. Its getting custom painted and graphics by my bodyshop guy (its his box)box for two Re re10s a couple years agotransmisson line for an old school kicker comp2.75cuft box for a 12" alpine type R in an accord Quote Link to comment Share on other sites More sharing options...

Rms is 2000, with many people putting 3-4kwatts on emthis setup was off a 2200wrms amp. 2 sealed group d batteries. box was around 5.8 cubic feet net with around 70 square inches of port area. tuned to 35 hertzThis box design set a record in a texas comp Usaci organization SB3---he was 9dB louder against his competitor...that is huge difference 3dB sounds like "double"had min. space to work with so it was only 3/4 inches thick, but had ALOT of bracing. (baffle was 1.5 inches thick)entire box was resin'd to help make the mdf more dense and smooth air flow. also on the outside to protect and help the line-x stickthis is 3/4" allthread very strongbaffle is onthe guy i built it for desided to paint flames on it...wtf?installed in hhr Quote Link to comment Share on other sites More sharing options...

zerocrash Posted March 4, 2010 Report Share Posted March 4, 2010 Cool stuff man. I'm currently running 1 Kicker L7 15 in a (just under) 4 cubic foot box tuned at 30hz, which is being pushed by a Kicker ZX750.1 in my Cherokee.My SPL meter only goes up to 130db and I hit that at less than 3/4 volume.

rawlins87 Posted March 4, 2010 Author Report Share Posted March 4, 2010 How many dbs are you hitting with 4 18s in a Ram?? 150+ on music on the new termlab. 150 on tones will be too easyS10 - Time to use some of bed for airspace.Either on is getting hacked up with a blow through. From the bed to the top of the cap is only like 33 inches so i cant stack the 18s tall. And its only 50" wide so there will be no room for a port. I might have to do a sixth order. From what i can tell so far I can do 2 or 3 without doing a 6th order. I know i can still hit 150 with 2 but I want it to be devastating like 4.
