I'm new to box building as this is only my fifth box to make. I want to make sure I'm not going to totally ruin my sub. It's nothing fancy just an Audiomobile elite 2208. Manufacturer says it's designed for a bandpass so might as well build my first with it. Manufacturer suggest largest sealed box as .65 ft^3. So I went with that for the sealed section (net) and 1.4 ft^3 for the ported section. 1.5"* 12.5" port @ 12.75" length for a tuning of 47hz. Let me know if I'm way off, as I'm sure being a noob I am and could use some input from the pros. Thanks in advance
T/S parameters RMS- 400 w Fs- 38 hz Vas- 10.9 L Qes- .58 Qms- 3.2 Qts- .491 Sd- 206cm^2
