Heres a little design i came up with for 2 SA8s the box is 1.27 cubes before displacements with a 3" areo 10.75" long tuned to about 35 hertz. I plan on putting this in my 99 tacoma extended cab behind the drivers seat. Comments and suggestions are appreciated!

good tuning. those subs will love it.

and is that 1.27cu6ft each or gross?

Thats a little small IMO

If its 1.27 before then your going to be ~1.07 after sub displacement. You need to be ~1.2 after all displacement.

That's 1.27 gross before speaker and port displacements I think It comes out to roughly 1.02 after displacements if all my math is correct. It gives it about .5 cubes per sub which is what's recommended.

Thats probably only after sub displacement port will take up even more... You need 1.2 after at least

Recommended .6-.7 per Jacob. I JUST finished my build and was dealing with spacing issues. I'm at ~1.18 after all. Subs are .1 each.

Yea I knew subs were .1 each I thought recommended was .5 to .7 per sub guess it's back to the drawing board lol thanks for all the input guys I'll get this figured out

Try adding an inch somewhere and see what you get...

After sub and port displacement you're looking at 1ft^3 with a 39hz tuning...say bye bye to any low-end you were hoping to have.

Ok I went back to the drawing board and came up with a new design that gives me 1.43998ft^3 before any displacements. I figured the port displacement to be around .03ft^3. The port is still a 3" aero at 11.75" in length and it is flared on each end. Since the subs are .1ft^3 per sub this should come out a little closer to the 1.2ft^3 at 35Hz that I was shooting for. The tricky part in trying to calculate the port displacement was trying to compensate for the inner flare of the port but I suppose that a few thousands of an inch isn't really going to affect the tuning to any noticeable degree? Again any comments or suggestions are greatly appreciated, you guys have been EXTREMELY helpful thus far! :peace:

I hope you don't plan to stick with that baffle board.. looks REALLY weird

yea i thought the same thing when i finished it but i was too lazy to change it lol. Im gonna get rid of those rounded corners so it fits square with the rest of the box.

go with a 4" aero not a 3".

go with a 4" aero not a 3".

A 4" aero would be too long to mount on the front baffle like i intended, the only place I would be able to mount a 4" would be on the side of the box. Id rather have the port and subs both firing forward.

I need a box for this exact setup, what are your overall dimensions?

My friend and I made a design for these kind of subs not too long ago, a guy bailed out on us when he wanted a build for them. I could post up the dimensions when I get home. If I remember correctly it was tuned to around 33hz.

Had quite the bit of port area, it uses a slot port though not aero.

Overall dimensions are 24 1/4"w X 10 1/4"h X 14"d

I've got 2 3" ports, both 10.7". The 3" port will be fine.

Finally got around to making a sketchup of the new design. I fixed the weird baffle board too I think this one looks much better! What do u guys think?

Here is a new design i came up with this one is dual chambered! Each chamber is .75ft^3 with a slot port tuned to 32hz. I like this design much better. Slot ports FTW!

I have 2 in my wife's car in 1.2@37hz and it crushes lows and has a very flat response.

Wow, a TL! You don't see those often around here. Have you built it? Any more info?

Sorry, been away from the site the past couple of days. I just took the max dimensions that he gave and came up with the design from there. It should probably be a little shorter in order to have a smaller taper ratio. I just wanted to let him know that he had more options with the dimensions he had available. No, I havent built it, but will be building one soon with my 12" IA DP.
It's kind of funny actually. I sent off a project assessment form to a VERY popular enclosure designer that everyone seems to rave about for my 2xDD1508s. I mean, I can build sealed, and ported enclosures, but I just wanted to see what he would give me. I sent him my max dimensions I had available and what I got in return was those max dimensions (I must be a genius), in a tapered T Line variant. Well, I reverse engineered the design he sent me and I pretty much know his method of making these things. Without even looking at his specs, I was able to recreate what he sent me to 1/100 of an inch, and it was dead on. Now, I don't know if the dimensions I gave him was just the perfect size for my design, or if this is just a method that cant go wrong. But, I intend to find out. I've done tons of research on them, and it just may be somewhere in the middle. I will find out soon enough though.

Correct me if I'm wrong but isnt a 3" aero WAY too small for 2 8s? hell would a 4" even give you enough port area?

Sugary Monkey

Don't get me wrong I like the TL but this is going into an extended cab Tacoma so the port would be firing directly into the side of the cab. I think the subs forward port up will sound much better but thanks for the idea. I've totally scraped the aero port idea since the dual chambered slot ports at 32Hz will give me much more low end than the 3" areo at 35Hz. Plus I like slot ports better anyway. I just ordere my subs today gonna start building the box when they arrive!

port firing to the side will get very loud in that truck. I think there's about 52" of width to work with, so you can go up to 48"and still have plenty of breathing room for the port.
