Okay so I want to try my newly rescued 2203H in my L65s. They fit but I can only use two screws, however with 1/4" soft foam gaskets they seem quite firmly planted. Problem is, outside of crossover issues, I just can't get my head around optimizing tuning frequency. Volume of the cabs is around 2.3cu. ft.? existing port is 2 13/16 inches ID. Calculators say around 13" for tuning frequency of 20hz. But where do T/S parameters enter the mix? And how do I determine best tuning frequency for this cab/room? Fs is 16hz. Is 20 hz too low? Either for the driver or the room? So far they sound quite good in terms of extension but not quite as loud as the 122A. Most appreciated
Btw, I also subbed in 104H-3
