Box Design Question

Recommended Posts

So im building my first spl vehicle and im trying to decide what box to build. now i have made a couplke of posts on here before asking the same question and the general answer was test test test. so i put dual 10s in a sealed box and tried a bunch of different locations doing sweeps. the following is what i got:

129 @ 59hz subs pointing back @ the back 
130.5 @ 56 Same config same volume 
127.8 @ 56 Subs pointing back @ front of vehicle 
128 @ 58 Same 
[email protected] 65 Subs poiting forward @ back of vehicle 
128 @ 64 same 
124.4 @ 57 subs forward midway up 
120.6 @ 63 subs forward @ front of vhecle

128.9 @ 65 Subs poitning back as far back as it could go 
130.4 @ 58 subs pointing back midway up vehicle 

so i was hoping to get some suggestions on what type of box i should build. i have 2 12" aa Havocs and its going into a 1992 mazda 323 hatchback. the one box i was thinking about doing was suggested to me through user jeep&bass. it was subs and port all firing forward. so i was thinking of trying that but facing the rear of the vehicle. so if anyone has any other suggestions of something that might work well in here i am all ears! Thanks!!!!!

if i design you the box, would you actually build it? not trying to be a dick but i've designed many boxes straight for spl comps and spent time doing it on this forum and almost no one build them, i've had few good scores in the past btw

so a couple changes i have made:
i have taken off an 1/8" too save on wood 
i have decided to add 1" dowels between the sub going to above and below the port 

now doing those things has lost me some volume and i am at 3.33 now. i am a little concerned that this is going to be too low for the subs. I'm using 2 12" AA Havocs that i reconed with a couple of upgrades

box is too big tuned to low, specially for that specific cabin, try a 15x15x15" external dimensions box, one sub up and one sub back, 8" aeroport facing to driver´s side about 16" long, should do around 148 dbs on 1k and close to 150 on 2k
