On-axis, and off-axis 30 and 60 degrees:



Box is 10 cm wide, so the diffraction peak is a bit above 2k.
 
In-room response - bass in sealed box seems to be -3 dB at around 85 Hz as predicted by the model:



Not bad for a $12 driver.

(Note: these ones have been sitting on a shelf for years. So the current ones may be different for all I know.)

Any comments or thoughts appreciated

I've spent the time since listening to these in a computer/desk setup. Stonking bargain. Assuming you don't mind a bit of EQ, but then again I'm starting to think that about all speakers...

Thanks for the post.

How big are the cabinets?

Yeah, most speakers need some type of eq.  I like the adding another driver eq; buy two pair, run one under the other, roll off with single inductor (hopefully).

Pretty small, about 2.5 liters sealed. It was one I had before. Not a lot of low bass obviously.

Two drivers is a good suggestion. Maybe a bipole would work too.
