[QUOTE="Robert_E, post: 243745, member: 853"] Somehow it seems wrong to have to apply 9dB! boost right at the tuning frequency. It sounds like the driver is being overstreched far beyond it's capabilities. That's why I would like to see some unEQ'd graphs. Abu, don't underestimate the [s]power of the dark side[/s] importance of smooth (non-turbulent) airflow, into, through and out of the ports. Round-overs are important and become more important as the air speed rises. I mention this since it doesn't look like you even have space for round overs on the port edges. Look for a program called flareit on subwooferbuilder.com to see how your ports do regarding port air speed vs round-over size vs noise vs port compression etc before you start building. I learned to be mindfull of this through someone else's mistakes :D ;) [/QUOTE]
