Greetings fellow bass heads, this is my first post. I work in the pro audioindustry primarlily building analog gear for recording but was recently asked to builf a couple of cabs each using one Eninence Kappalite 3012lf.. My design includes two 4" Aero ports in each cab, due to the guy cutting the wood on the big saw a home depot I realized when I got home that my cab went from 2.7 to 2.52. The original design called for the port lenght to be just over 10" giving me a preferred 4" clearance from the back of the cabs (ports are front mounted). So I now have some 90 elbows and am turning them down toward the bottom of the cab....my problem is figuring thr length of the 90's. Aero Port says I need one lenght and Eminenc3 says another....trying to tune it to 44hz. SO I al also a bit oconfused about measuring the port length, di I measure from where the flare starts or end of flare to end of flare? Again the ports are Aero ports and I have to use the 90 degree elbow to turn the inside port down. Any help would be freatly appreciated and I am glad to be here. Thanks in advance! I'll try and post some pics of the progress asap.
