It's not as bad as I'm making out but the corners do look a bit gloomy from where I sit, but maybe again it's because I sit further away from the track than I ever have done. And yes the speakers are poor if non existent where I sit. Having said that, at King's Lynn on Saturday, couldn't hear much there either.
I sit in the back straight stand exactly in line with the start. Literally the last row of seats in that stand.
