4-18 cubic ft. flared slot ported build using 4-B&C 21DS115-4 Drivers
![]()
Boxes: 4 18 cubic ft. MDF Flared slot ported boxes
There tuned to 15.33 hz.
Drivers: B&C21DS115-4 ohm drivers
This all started a while back.... I reached out to LDT02 and was asking for his help with the Dayton Ultimax 18's and was going with those in a slot ported box. Then once I started building my Titan-615 LCR build I stopped at @mtg90 house to pick up the crossover boards and we started talking about what drivers I should use. He suggested the B&C driver and after a few messages and phone calls he modeled the new driver B&C just released after seeing what the SW version would do via winisd that parts express sold. This new driver made 2-3 db more across the board compared to the SW driver and was just a little more money. So since I was this far into it I figured why not buy these new B&C21DS115-4 drivers. These will make some serious noise as you can see from the graph below.
These new drivers are also very sensitive and will take less power to drive them which is a huge plus!!!
I'll be running the drivers with my inuke 6,000's and the will be a perfect match with power.
Here's a few graphs of where i was in my room and were I will be.
Yellow and blue is the new setup and pink and red is the old setup.
