Design input for hivi 3 way

Hello, this is an enclosure design I came up with and wanted your guys input. I know it's a bit rough looking so I would like to take the time to explain it a bit. The bottom slanted part of the enclosure sits two hivi m8ns. Using winisd I went with a ported box with a volume of about 1750in^3 tuned to 27hz. The port runs the length of the box at 7.75in by 1.75in and is 46in long The top portion is open with the two dividers as braces. I haven't decided on a mid or tweet but I liked the idea of running 2 tang band w4-1052sd. I know this a rough first time around but your input is much appreciated. Thanks for taking the time to look and respond.

The idea of the port is pretty good -I do like the looks of it, however you will definitely want to move the mids and tweeter much closer together. Also can you get 1750in^3 out of the space you have portioned off now?

Also - with a port that long, make sure you look into the port resonance - your two woofers should ideally be cut off well before this resonance occurs.

Great, thanks for the response. Yes, 1750 inches cubed out of the woofer portion not including port. I will move the mids and tweeter closer together. Should it be more towards the bottom for phasing? Or..

Not sure about being more towards the bottom. However, you want to keep the drivers within a 1/4 wavelength from each other (at the crossover frequency) to keep the sound "together" - although a 1/2 wavelength is usually considered fine by many.

Also - any particular reason for WWMTM? It may be simpler with just a WWMT configuration (as far as the crossover is concerned).

No reason for the alignment and its all changeable and workable. I'm new to this and trying to understand the dynamics of a well thought out enclosure.
