i have the OEM speakers, pioneer DEH-P88RS II radio/headunit, audison LRX amp, peerless xxls 10" sub.
i use time correction and the 16 band EQ in the headunit, also using the HPF (high pass filter) in the headunit to cut the deep bass at 50hz from the oem speakers, this way i dont stress the OEM speakers with sub bass.
the OEM speakers are great, but i would like to have a little more kick from them.
You can push the filter to about 70hz to get a bit of kick from the mids to help sharpen the sub bass at the subwoofer - you will get added punch on 808s and deep kick drums without sacrificing much power from the standard speakers.
To answer your question OP, i always thought they were Bose, but im still unsure. Very very good sound quality, i havent even changed the HU cos im obsessed with OEM look, so if i was to upgrade it would of been the becker grand prix 7900
I'm almost certain this was covered a few years back and they turned out to be an unbranded make, made by Rainbow (which are high end builders), which in fact outweigh Bose.
That's the good thing about Seat..you get all the good products but a fraction of the cost, purely because Seat don't scream about it and put product badges everywhere. Subtly is key
Hello the speakers are from Blaupunkt
On my ex-leon I installed an alpine HU and a 4 channel amplifier, 2 chans for a 12" woofer and 2 chans for the front speakers and 2 HU amplified channels for the rear speakers and oh wellthat was enough

I always had the idea to replace the front speakers with a focal set but I never made it as the blaupunkts sounded so well...
As above - Rainbow
