Define what you mean by "clamshell". you can do multiple styles of clamshell enclosures.

Ported? 4th order? 6th?

correct. do you want a cookie? you dont need a clamshell for an 8th order

hahaha very funny i know that. it seems like having a clamshell would just make it simpler but thats just me..

In all seriousness, figuring for a design type before knowing what your vehicle and driver combination will like optimally is like shooting a flying bat in the dark. But let's say either you have figured for this alignment and it proves to be optimal for your vehicle and listening preference and design goals, or you just want it because of pure change and chance that it might just work extremely well. Either way, it will take some time to figure the proper alignment for you and many unkown variables exist right now that would make it impossible to perfect. So, first thing to know. Is, what response does your vehicle have as a transfer function and what resonances are peaked and nulled and what is the first and second order resonances mainly? This will determie what kind of design approach you will need to take for a proper response.

Now, if you do not care about proper response and just want something nice and loud without knowing what it will sound like yet, and a clamshell setup is the only thing you are open to, then as far as figuring a design for that, it can still be done with moderate output with standard sound that is satisfying for many people in the audio community. Just need to know still, some information to even giuve you a start on how to approach this type of design. I could design a clamshell compression horn for it, and give it theacoustical properties of a 6th order, along with controlled excursion at lower frequencies with characteristics of a sealed design, but will this be optimum or even possible to get a decent response from? Well, again, that will depend on many factors not known yet. So as far as giving you a start, it cannot be done effectively without knowing some info for the design to be even calculated as functional. I'm not going to suggest any design ideas until some parameters can be given. Other than that, if you are interested, I could help as much as possible to a point.

Just build it. Then test. That is the only real way to know what will work and how it performs.

I have a ported clam similar to Frankie's that plays consistant from 25-55hz. small port with a large chamber.

That is completely incorrect. If everyone just built and tested, there would be so many people out there that would have to keep building it over and over. Granted, a few lucky ones will actually like the sound, but I guarantee some of those are oblivious to what real sound sounds like and will not notice that something is not right.
Argue with me all day on this if you like....I will win the convo, trust me, but the point is, do not just build and test without some sort of goal that you try to aquire in the process. There are many ways to calculate now days, actual accuracy of a design well before any wood is cut, and Im not just talking about making sure its loud enough...Im talking about every bit of needed info on a design: excursion control, acoustical to electrical power efficiency for amplifier operation, response curve optimization, proper cutoff point, low level output for efficiency levels, resonance optimization for either specific frequencies or to control peaks and nulls in a response, environmental factor control within the response, proper placement and positioning of the enclosure output, phase correlation between the driver and port or mouth (depending on the type of design), smooth response control for correct timing, proper or acceptable impulse response again for smooth sound and timing accuracy, and many other factors not mentioned. Do you see how just building it and testing it is not acceptable?
These are the type of comments that I am trying to fix in this forum among the many threads in here. The fact that so many people here just rely on simple calculations of port characteristics and enclosure volume/displacement makes me upset. Not to mention that the "port characteristics" take no consideration to the driver parameters installed or the environmental factors that I have mentioned in a few threads already. So, please.....do not just build it a test it blind. if you want help....I can help you here.
We have already determined that you want a specific type of design, now lets figure out how to optimize it for you, ok?
