I’m new to forums ,but here I go . I have a 2015 Ford F150 supercrew with the 2.5 LMI Welding seat lift .I just purchased 2 DD710 F the latest revision, I have around 3.3 gross cuft minus woofer and port displacement . Im trying to tune port around 32hz how do I found out how big and long the slot port needs to be …why maintaining correct airspace …Yalls help is really needed. Thanks in advance

I have a 2015 Ford F150 supercrew with 2.5 seat lift . I need port length and area for 4 Sundown U 8 my box will be 3 .3 cu/ft ,I’m thinking I should land around .75 per sub after port and woofer displacement tuned @32 hz

When you have time can you elaborate on 3 common wall slot !!I It’s Thanksgiving so enjoy..

Hi there - Thanks for responding Sundown recommends 12 - 16 inches of port area per sub. So do I need at least 48 sq/in of port area. Do you recommend maybe trying area port or stick with slot port .Just did some math 48” sq/in port area tuned to 32hz port length is around 33.39” long does that look right . Thanks again Happy Thanksgiving

I’m new to forums , hope on the right thread . I have a 2015 Ford F150 supercrew with the 2.5” seat lift . I’m running to 2 RF T1500 Bdcp. I’m in limbo about running 2 Sundown U 10s or 4 Sundown U 8s . If I go 4 8s I’ll have around .75 sqft per sub after displacement . Box will be tuned@ 32 hz with 42 sq/in of port area . Does this sound right
