These are the very rare and much sought after 2001 Nissan Maxima co-axials. 87 cents each!
Absolutely no bass in the sealed .5 cu ft cabinets. But, the image is good and the mid-range decent. And less than $20 and 4 hours (which includes spraying the 98cent cans of red paint) in them.
Think I should drill about a 2" hole for a little bass action, no way there's any T-S parameters for these!
