This rig is too much! I'm getting chest pains!

Keep your nitro glycerine handy then! These center back speakers a re working of the monitors from my previous two channel studio. The bass lines have two KEF B 139s in each. The mid lines have Dynaudio M 75s. There are first order crossovers to Dynaudio mid and HF domes. First order crossovers are the toughest and took me 10 years R & D! Although it seems like overkill these speakers effectively give the system four subs, which many people are now advocating. This system does not have subs in the usual sense, as four of the seven speakers cover the entire audio range, and have a bass performance that any sub manufacturer would envy, and yet theses are totally integrated speakers not dependent on subs.
