The wooden side panels included with your EVO CD and EVO 75/150 are made from real wood. Due to natural variations in wood, it's possible that the side panels may not perfectly match the existing ones on your EVO 75/150.
We would suggest placing the EVO 75/150 side panels on one side and the EVO CD side panels on the other side of the two units, to achieve a better match.
If you are disappointed with the difference in your side panels, please do contact our support team directly who will be able to send you a new pair of wooden side panels.
While we can't guarantee that they'll be an exact match due to the nature and materials of manufacture, they may provide a closer match.
