Octavia mk2 door Speaker's what size?

What size are the speakers in the front and rear doors on a 2007 Octavia vrs ?

I've just got the car and only thing I'm disappointed with up to now is the sound quality is shocking ...

My 2003 superb speakers where well better.

Its a shame because the Columbus unit sits sweet and smooth looking and then try and turn sound up a little a bit and its like 90's Clio .

Anyway so I don't have to take the door cards off just to check and put em on off just to take them off again ,.

I was just wondering if anybody knew what size Speaker's they are
