It's been 2 months since I started with the house extensions which includes a dedicated room. The room is 7.4m (L) x 4m (W) x 3.3m (H). I will have 2 rows of seating to sit 5-8 people. The speaker configuration will be a 7.1 set up which I can upgrade to an atmos 7.1.4 as soon as I change my processor
