Pro-Linear ?

[strader]

Anybody heard of these guys or can tell me something from past experiences ?

I can get these speakers:
PTX50TBL (black)
PTX55BBL (black)
PTX55CBL (black)
PTXSUB10BL (black)

Here's the site: http://www.pro-linear.com/euro_series.htm

They look very nice not sure if they are good or not.

And what kind of amplifier do I need to run these babies.

Thanks for the help.(if there is any hehehe)
