I have an Alpine SWS 10" D4 subwoofer in a custom built slot ported box of 1.245 cubes gross with .75" thick MDF all around. After slot port and sub displacement, I calculated the box volume to be about 1 cu ft. with a 35 hz tune. The box is 18.5" wide, 12.5" high, and 13" deep. The 13" depth and 18.5" width can’t really change so it fits and clears the folding seats. The height can change since it’s in the back of the third row of my Sienna. I do like the current box and it does sound really good, but I always have this bug to improve things and I want to try this subwoofer in a similar box with a Precision port from Parts Express. https://www.parts-express.com/precision-port-3-flared-speaker-cabinet-port-tube-kit--268-350 with the same 35 hz tune. The current box has a slot port of 1" wide by 11" high and it’s about 21.75" long with the subwoofer on the same side as the port on the 12.5" side. I'd like to keep the subwoofer facing the tailgate but the Precision port would have to go on the end, assuming it is cut to 13.5" long, not including the flares.

Number of subs: 1
Subwoofer type: 10" Alpine SWS D4
Power to be used: JBL GTX 500 500 watts RMS @ 2 ohms
Goals: SQ > loudness, more towards accurate, tight bass, and good transient response. I'm looking to gain some efficiency and SQ over the slot port box with a Precision port box.
Listening habits: Decent volume, but very rarely more than 2/3 volume. It’s for my wife's minivan
Music: Pop, Rap, Rock, Alternative, R&B, Soul, she loves it all.
Thanks in advance.
