How to optimize enclosure for mini speakers in WinISD?

Hi guys!

I'm trying to learn how to better optimize sound for small speakers like in gadgets, etc. I picked this small speaker online just to learn, and the specs gives very little T/S parameters.

A38K 1/2" Mylar Cone Full-Range Speaker

I'm able to input the driver like so in WinISD, and I can create a new 'vented' project. But for a 'closed' one it fails and says it's out of bounds. Do I need to guess other parameters or am I missing something?
An externally hosted image should be here but it was not working when we last tested it.


Thanks!
 
With a lower frequency limit of 800Hz, this tiny driver produces no bass. No enclosure is going to optimise bass which is not present in the first place.

A baffle of small area, or indeed no baffle at all, would suffice for installation in gadgets, toys and model railway layouts.
 
Seems like you should treat it like a tweeter, any enclosure at all is going to be large enough basically, and you want to protect the rear from any other drivers in a shared enclosure, along with a high pass filter to keep from bottoming this out.
