At 4.5 cu. feet and a 4.5 inch port it would seem that the 2-Pi tower would have a port frequency of 49 hertz. Does the insulation slow down the airspeed this much ? Or is it because the sound has to pass thru 2 sheets of insulation ? Does the insulation act like a air-port like the dynaco used ? Thanks.
