Hi Pete, I hope to learn some advice from you regarding your feature wall project. I'm currently building not a feature wall but instead a feature 'shelf'. This shelf will be made from Nyatoh wood and it will house my Pioneer Plasma and Pioneer LX/MA RX1 home theatre. The speakers will sit openly on the shelf (not surrounded by books) but my concern is that they'll be no more than 5-7cm from the wooden backing and thus that will affect the sound. I read that you had special wood flown in from the UK and also extensive use of rock wool. It's probably hard to ask for detailed advice but would you be able to share some thoughts on wood and acoustically treating a built in shelf. I'm also thinking of adding other items like Auralex to help but need some advice. If you can, it'll be greatly appreciated. Thanks. Mark.
