MJ-18 questions about 3rd, 4th, -8th order BP boxes.

[80INCHES 5,000+ posts]

if all goes well with 80" inches knowledge and assistance I am going to fit two MJ-18's in my van to see what they can do vrs my pair of 10" Orions.

Im dying to know if I am going to hit harder or not.

If your reading this 80 , what do you think ???

my Orion P series 10's hit nice and hard, but have a 17mm Xmax , will the pair of MJ-18's with your box plan and my Orion HCCA 250 amplifier supplying ONLY 500WRMS to the pair @ 2ohms get louder than my two Orion P series 10's ???

if u want to be louder bassed off the power u have

do 6th order parallel tuned box

have the rear chamber in 10 cubes tuned to 35hz with a 120 square inch port

playing into a 5cube ported chamber tuned to 75hz with 280 square inches of port area

u should see a big difference
