Hi there. My system consist of 3 M&K 95 in walls as the L.R.C and M&K 26T as surrounds connected to a Yamaha 3067. I need a sub to complete the set up and would value your opinions/recommendations as to what I should do as per thread title or any other suggestions. My listening is 60/40 for films and my living room is 5m long 6m wide. Thank you.
