That's a bloody good effort for a first go at building a box!

 

I'll be interested to see how it changes how it sounds.

Cheers ?.

I have a bunch more/better mdf so im tempted to make some different designs just for fun.

If you do make a second one use some nut inserts or there are cheaper ones that hammer in from the back.

Plus through some bracing through the middle. If you are being super accurate then add it’s volume to the box size. 

 

Also ratchet straps are good for clamping things while waiting for glue to dry. Though usually when you have 45 degree cuts to join.

There's a huge hole in the front of it.... aaaaaand there's a massive port in the back of it ?

Forgot to mention above that I installed the sub yesterday and have used it a little bit since. Definitly a lot louder especially at lower frequencies and if I turn if up my mirror shakes a whole bunch more than it used to. However sometimes, usually in the mid/higher frequencies (for the sub) it goes real quiet and lacks the punch it used to.

We're talking about like 350w here. 18mm MDF isn't going to move, don't worry about bracing it. Nutserts, each to their own, I've only used them with ridiculous systems where the sub was coming in and out a lot.

Curious, the DD designs usually tune quite high (40hz is standard for them) so should be quite a punchy box. One thing to try is removing the polyfill from the box as this will make it behave like it's larger than it actually is. Other thing to check is that your low-pass filter isn't set ridiculously low, I'd aim for somewhere around 80-100hz, try turning it up just a little and see how that affects the sound.

I checked low pass. This is the Sub below. Its a little hard to see where they are pointed but looks about 70hz

 

Ill turn if up a bit and if that doesnt help ill pull out the polyfill.

If the line is the indicator, then it's either set to like 70hz, which I would consider quite low, or about 150hz, which I would consider quite high. If it's currently on the low side, try setting it right in the middle, should give you roughly 100hz. Maybe a pinch to the left, approx 11 o'clock.

Did that. Pretty sure that fixed it.  Sounds awesome haha.
