It's perfect box size.
Qtc = 0.75
Power limit and stroke limit overlap below 30Hz (perfect - @1000W it will give exactly Xmax from 1Hz to 30Hz and will not overtravel. Above 40Hz power limit will deliver 117dB ).
117dB from 40Hz and up
109dB @ 20Hz
I cannot help with your figures but that’s a beautiful looking sub. Great work!! How do you like it’s performance?
The Dayton plate amps have been dyno tested and delver very close to their 1200 watts ratings.Hi Will P
Thanks for spending your time and checking out the parameters it’s much appreciated. Well it looks like l got lucky with the sizes .
The sub sounds great but l must admit l have been fairly conservative with the powers as l was not sure on the cone excursion. I am very surprised at how responsive that carbon fibre cone is . l am using the Dayton 1200 w amp but l don’t think it will output any were nere 1200w so the driver should be safe any
I am looking forward until tonight to give the sub a resend workout .
Thanks again guys for your help and comments

Thanks for sending that trough interesting video hopefully the 1200w amp preforms as well 👍Here is a test on the 1000 watt amp without the DSP.
I posted my sub build if you’re interestedI dug out the good old edge of tomorrow and increased the volume until the minister of no fun started grabbing her wine glasses and she had her grumpy face on lol. I have the lLLEGAL BASS CD shall give the Sub a good workout with 3 kinds of bass track tomorrow when the wife is out.
Definitely interested in seeing you build also make sure to send me a link when you start your post.
Tru basshead!I have the lLLEGAL BASS CD shall give the Sub a good workout with 3 kinds of bass track tomorrow when the wife is out.
Been working away a lot this last few months . Been home for a couple of weeks now finished of my front speakers and modified my centre channel with a 2.5 way x over everything running in at the moment haven’t ran any EQ at the moment . The sub has about 20hrs on it and starting to sound better already . The base is excellent get down to low 20’s at a guess the hair not standing on my arm lol. It pressurises the room well and if you did not know were the sub was you would not find it . Live die repeat was awesome and that opening bass response is sounding better every time it gets played . I am running the amp at - 03 so probably 95 % power and it loves it , the wife is not that happy with me braking her wine glasses in the kitchen cabinet lolBeautiful build! I bet it sounds awesome. Are you running any EQ on the plate amp? How do you like the Ultimax so far after a couple months?
I am considering replacing my aging SI HT18D4 that has begun clattering with a UM18-22.
