Nice build and pics! How come the enclosure did not have a BP8 type response in the measurement?

Omg, did you play the 2 subs while in the car?

Why do you model only to 50hz? Lowest key on a piano is 27.5 hertz.

That front chamber looks like it needs more than Hornresp's simple bandpass sim too to properly simulate.

hi bp1 the pic show that its not big to bring with the car. and yes i modeled it 50 hz because diy thailand dont have good driver. if fs of driver is lower but the cheap driver has short xmax. and i also want a small box so that i found some driver.

What does the impedance curve look like? FR can be corrected by EQ, up to a point. The impedance curve can not only be used to determine Fb, below which no boost should be applied, but also determine if there are any significant sources of losses within the build (e.g. leaks, panel flex, etc.)

a friend from western sent me some pics. he is a dj in Ko Pha-ngan thailand. he used bv18 sub and he wanted the new sub which it aws not long throw. so that he asked to me. the bv18 thai diy had ever asked me about the design. i designed bm18 as the same bv18 after i saw that design. but with dj friend he wanted near field sound. i think ev mtl design it will good for the job.
