Now post for the second time Can someone quickly calculate a box for me? Sorry, it’s not for the car, but for home use!Do you need the data for building a BR box though: Woofer chassis: 400/1200 rms/max – 8 Ohm 22-35 000 hz 99db resonance 34 hz Qts: 0.186 Vas: 223 l basket diameter : 386 mm insert deep 154 mm. So I already got wood, 19er mdf! I still have to cut today with the circular saw! How many liters do I need to get out most of it? Would you like a pressurized bass for techno /Hardcore! How big the box is, doesn’t matter, even the shape! so my questions: 1)dimensions box (liter) 2)BRR diameter 3)Which reinforcements inside the box or additional plates for better sound conduction Thanks in advance mfg
