Latest box design 4 SA-8s

[Moble Enclosurs 10+ year member]

my point to plain and simple. i like that moblenclosurs is giving complex advise but i dont think its needed unless super serious about sq or spl. other wise build simple and it will sound good. otherwise ur gonna pay a **** ton for designs and builders to get it right for you. and yea 4.06 but after all displacments thats still like 3.5 cubes or so. too big bro

I am going to have to agree with you on this. Solid points. I have seen people recently that came to me for designs that spent a lot before, but that's because they didn't come to me first,lol. Seriously...no joke. But good points man. It really is that simple if you just want something to play with. Plus, you never know...you might learn something about your vehicle that you never knew before.

Hey, that novel is going to help people. There is a lot more information to be known that this about proper audio, so be glad I'm sharing it.

As I can appreciate you sharing your vast knowledge, frankly I don't wanna read a essay about it. I read through most of it then stop. Not talking down cause you have a lot of knowledge but anyway you can shorten them up some?

Lol ok ok. Ill do my best. Sorry for the length. When I'm on my phone, it doesn't show very well how long it is. Just 2 lines at a time,lol. No problem man. Thank you for being honest.

No problem. I post from my phone also so it seems like a lot more than it really is. I do appreciate it though. Its very foreign but try picking up on it

alright so My BASIC question is.. If I am trying to play from 28ish-70 and sound decent but still get loud (I would like a 140+ system.. I am pretty sure with this it can be done.. But I don't want it at 50hz and it not play anything else..) would 3.2 after all disps tuned at 35hz work.. the cab is approx 64W x 72L x 40H

It seems it will help comprehension and focus, so for that, I'm game. Now let's get back on topic lol

You have a great response range in mind (actually exactly 1.5 octaves), and I can help you further if you like, but not for free. What I will do is help with general info for free as this is a forum for questions and answers. But for calculating anything for you I can finish the design if you like, PM me if interested. If not, just go by what everyone else says that may help with getting something ok for a box, and you never know, you may love it.

I will say that 140dB for 28-70 will not be +/- 3dB with that design, but hitting 140 somewhere in there, likely.

I'd tune to 33 and add a 45 in the port. To me 35hz is too high if you want an emphasis on lows.

What kindof output are you looking for at 28hz? You could easily 'tune' to 38 or so and get acceptable output up there. A horn build of mine was 'tuned' to 38 and played audibly flat from at least 32 on up in a G6. Cabin gain will take over, especially in such a small cabin.

not really for SA-8s, in a bigger box they seem to extend below tuning well.

OP,i think youre getting on the right track, somewhere between 2.8 and 3.2 after displacement should keep you from bottoming it out. I had 2 in 1.6 on2k and they never once bottomed out

I would like some output there it doesn't need to hammer at 28hz.. But I would like it decently loud in the LOW 30s as that is where most of my music is..

I think I am going to try 3.2 @ 35hz will make an add on port to bring it to 32 for testing purposes or I may tune to 34 and add in 2x4s for disp to get the tuning up if it doesn't do what I want
