Front vs. Rear Port

I port out the bottom or back of cabinet I tried front ports not my cup of tea,best is bottom porting [this is harder and more costly to pull off]next back.Only front ports I now use are slot ports for bass systems only[oris ref]If my customers would let me back port these cabinets I would but they like the look;).

Hi Duke, I notice little diferance with floor materials but I do include a damping pad if one has a very live room also inc cones or feet if one has deep pile carpets.Problem is spacing of port from floor and designing cabinets to have the free space below for the port this causes extra work for you will need funky bases or arched plinths,more careful tuning of ports, but it sure works. Loads the room with even bass pressure, allows easy of placement, systems so equiped can be placed near walls or far out in room since bass port is using floor for reinforcement I as a designer know distance from floor to port and can design for this with front or rear you dont know distance to walls just floor so loudspeaker with front or rear ports needs more careful room placement.PS if you use a bottom port in one of your designs I want a free T shirt .lol
