i had the pioneer tsd 702p and they are great for the money. best coaxs ive heard. ive had them running on 30-80wrms a piece and they sounded great. tweets are not harsh at all and they were able to keep up with my 15" on 1kw.
cant comment on the others. iirc , madisound has some hi-fi coaxes for a decent price. i havnt been able to find anything on them but they look nice. cheaper than the rest too.
depending on your budget, if you want good midbass and a tweeter thats detailed but not harsh, look at the morel, or hertz. The Energy line of coaxials may be your best bet!
