@mistersota Excellent Build! Love the idea of lower tuning, my friend and I are doing that on one of his subwoofers, but EQing it down due to cone excursion and port limitations. Looks like you got fantastic results as well. I am curious what are you using for DSP? I recently just got the Crown XTI 2002, but I haven’t messed with it yet.
I am curious about your cone excursion and your port velocity with this setup. I really like the setup, but I am not quite getting the same results as you in the simulation. Did you simulate cone excursion and port velocity with your filters (aka 6dB eq boost and high pass)? When I do this, it looks like the power limitations for cone excursion are closer to 400w. I might have the wrong information though. I am simulating a 4 cubic foot box tuned to 16hz using a 6dB boost at 20hz with a 4th order high pass at 14hz.
