I am very interested in OB and would like to see how OB speakers sound in my room. I have a pair of Adire HE 10's (Anyone remember them?). They are not OB, but my thought is to take the drivers out of their current box and install them into a quick and dirty H frame and see how they sound.
They clearly would not be optimized and I would be careful not to bottom them out, but is this a valid test? If so, is there a "golden rule" for H frame dimensions that I should start with?
Worth the time?  Any thoughts are appreciated.

If you're running them full range, you would be better to use a flat baffle. The H-frame would be for a large driver to augment the bass.

Thanks John. Regarding dimensions, is there a general rule I should follow when making the baffle?
The driver is 10".

The general rule is that the wider the baffle, the lower the frequency at which you will need a woofer to fill in the bass. I think the best way to explore it is to use a baffle simulator, I find the Edge simple enough to use, and there are a couple of others I've heard of but haven't used: ABC Dipole and BoxSim.
