Hi guys,

I don't know because I have not heard one of these taiwanese drivers, but I do think philips drivers are truly a great deal.

I will try to explain : (even if I'm the one who sold these drivers to Pascal, you may laugh but I really think what I say )

You can say of most philips vintage drivers that :

They are cheap (even prices are increasing on ebay)
They are made with very light and rigid paper cones
They sound clear whith detailed highs and clean fast bass.

I currently own the Philips AD4200M that is a 12 inch alnico driver with treble cone.

I listened PHY hp (FRENCH !!!) 12 inch alnico drivers with coax tweeters last saturnday. These PHY are around 2000$ the pair.

Even if they are top of the line fullrangers made by a french (my country) maker, THEY WERE NO MATCH WITH MY AD4200M !

Think of it.

PS : I sold these little fullrangers to Pascal for 15$ the pair and shipping included, I don't think there is any driver in the world you can get for the same price which can sound as good

Richard Allan 8 inches are beautifully made english fullrange drivers. I'd like to listen them. But they are a lot more expensive on ebay.com than 15$ ....
