Hi I'm building a ported box 200cm wide, 53.5cm deep and 58.5cm high out of 2.5cm mdf with 2x16cm ports and an RLP18" sub. Does anyone have any thoughts on the best orientation for the ports and sub? Eg. front firing sub with ports on either the same side or opposing sides or the sub and ports on either side of the box similar to a sonotube but laying down?
I remember seeing in 'high performance loudspeakers' that changing the port position in a bandpass sub changed the port modes up high,although it was LPfiltered,the peaks were rather substantial. They didnt go into detail.
It doesnt matter hugely.But if you point it away from you,and perhaps form an acoustic low pass filter with the floor with downfiring then you can get some difference.
The major differences people hear are due to room modes and change of source position.
