[PLAN]18" FBT X-SUB 18 BANDPASS Subwoofer Modified Extended response to 35Hz

#Subscribe #FBT #Bandpass


I modified the plan so that it would play lower

35Hz ~ 120Hz

The original one only plays at 38Hz ~ 120Hz

God bless guys and happy building!

Check your mounting depth clearance first before you make this sub box for your speaker.

It has clear clearance on a 264 mm deep basket with the magnet with it.
