This is my latest project.
I wanted something that sounded better than 15 inch fullrange speaker on a stand.
So i decided on a 2.2 sound system.
Having already two large 18 inch subs i wanted something more portable, something that can be carried by one person, could still be called a subwoofer and not have problems filling large rooms.
That's why a chose a 15 inch driver (15NW100) in a box very similar to B&C Sub15. The final box has 110 liters and it's tuned to 42 hz (without any filling) with a 400 square cm port .
As for a midtop i chose an 8 inch (8NDL64) and 1 inch compression driver (DE250) on a Eminemce horn (H290) that i had to cut its sides so the width of the enclosure not get too wide.
Enclosure size is about 15 liters and it's tuned to 65 hz with a port on the back. Crossover point between the midbas and the de compression driver is at 1.6 khz second order.
The sound is exactly what i wanted.
The subs go fairly low, good enough for DNB, Dub and Dubstep with a fast and punchy kick.
I feel like these drivers can eat a lot of power, a lot more than what a TSA 4-1300 can provide.
The tops sound crisp. The midtop has kick and the midrange is clean and warm. The compression driver horn combo i've used in the past and i am still impressed by how it sounds. It has enough spl/power to be pushed to high levels, while still retaining a crisp sound. I am still at the first version of the crossover with minor tweaks to come.

I like the scale and proportion of this project, very sensible. What frequency are you crossing to the subs? Is the sub low-pass passive or active?
very neat, everything looks great apart from the stacked steel lamination inductor with lots of turns, is it in danger of saturation?
Tommus the crossover is a DCX2496. I usually cross the subs at 90 hz.
Kipman those coils are used in more powerful speakers than these(Dynacord VL212) The midbas drivers are 16 ohms so i had to increase the inductance.
At 500w per top i need two subs to keep up so they are safe while using just one sub per top.
