mopar221 Posted February 1, 2016 Report Posted February 1, 2016 Hey guys & gals. I have built 3 enclosures already for my 2 SA-8v3's. they all sound great for the subs being 8's off a SAE1000d. I would say @ 1ohm, but they actually read 6ohm or some crap. wish I would have noticed that when I bought dual 4ohm. should have went dual 2ohm like I went for the second set I bought for my dodge ram. anyway, I'm interested in building a 3:1 6th order for them in my blazer. I have done some numbers and need to know if they are correct, or close and would work. I have never played with a 6th order design, and I know there is some very intelligent people here. I have been a LONG time lurker. down to the numbers as I'm curious if I'm on the right track. Rear chamber (motor end of subs) spec's. Wood disp: 0.75 Sub disp: 0.16 Enclosure: 14"d X 32"w X 12"h - gross: 2.32cf - net: 1.55cf Port: 2"w X 10.5"h X 26"L - port area: 21 in2 - port area per foot: 13.55 in2 35hz..... Rear chamber. _______________________________________________________ Front chamber spec's Wood disp: 0.75 sub disp: 0.10 (not sure if that is correct, but close to it I think) Enclosure: 7"d X 32"w X 12"h - gross: 1.02cf - net: .52cf Port: 1"w X 10.5"h X 24"L - port area: 10.5 in2 (questioning this) - port area per foot: 20.19cf (questioning this) 45hz...... Front chamber. If anyone has the time to check these numbers and tuning also the port area info on the front chamber, I would REALLY appreciate it.
Triticum Agricolam Posted February 1, 2016 Report Posted February 1, 2016 I assume this for a parallel-tuned 6th order? Your chamber tunings are really close together, I don't think that's going to work well, you will probably get some cancelation.
