Hi,
The centre speaker compartment is 70cm wide with a height of 20cm, so it should be perfect for your centre speaker, it may be worth double checking your height measurement though. The cabinet is known as a the BDI Cassini in the UK, take a look at our product page for the
BDI Cassini 8629 for accurate internal measurements and a technical drawing.
BDI are one of the leading manufacturers of TV furniture, the quality of design and finish is as good as anything on the market, as for your other question please contact us directly.
Hope this helps you.
