My Dayton UM 18-22-18 build

Hi Guys 

just thought l would share my DIY build. I did not have any means at the time to calculate volumes and performance so my cabinet size was a recommendation. I was told 6 cubic feet and sealed was the right size and anything over was a bonus.

 I measured up my space and ended up with 550mm W  x.  700mm H. X. 750mm Deep . After driver displacement and bracing etc l am left with 211 ltr’s volume. 
l do have Winlsd now but have never been able to get it to give me the cone excursion graph properly. I put 1000w into the signal and it not on the graph l have dropped the wattage down to 10w and it showing 75mm + on the graph witch is impossible. So don’t know what’s going on there . Maybe someone a lot more savie than me might like to give me some figures for this sub .

A few pictures of the build l laminated the cabinet to match the TV unit to keep the wife happy.
