I stopped at BB today to see how the Insignias looked. They look fantastic for a $40 speaker! They have massive binding post that look like the ones on a lot of the big name Chinese speakers (Onix, Diva, etc). The driver, baffle and port look really cool.
If I had a little time I would buy a pair and do the mod that Danny Ritchie posted. I'll bet the mod'd speaker is killer for the sub $100 cost.
Enjoy,
