thing about speaker is that it all depends on the listener and type of music. If someone is used to the usual OEM sound systems, then yes, the leon is very good considering the price of the car.
But comparing them in general, they are still only just acceptable. It's a shame that OEM sound systems are usually just afterthoughts - but then again it
help the car audio industry.
I do remember the original leon speakers to be "not bad" though, and yes, the tweeters are Blaupunkt and the mids are Philips.
