Title: Re: HELP!!! Post by HellionDarklord on 07/22/23 at 23:36:57 According to the website the SKAR VD-8 D4 requres a vented port area of 11 inches. I just changed my port area to 11 inches and with a port length of zero inches... I need to know if the ported chamber volume iwll produce a resonation at all frequencies like the online calculator said.... (I found that onine calculator back in the early two thousands) I'm not the only one who says this box is like blowing across the top of a bottle. you can get a high pitch whistle, a middle whistle and a deep drone from the same neck by blowing across the top with your lips. Blowing at the outer edge of the bottle you produce a deeper sound and as you move your lips to cover all but a little bit of the opening in the bottle you get a higher sound. Lets remind ourselves that the volume in the bottle has not changed but the opening is being modified. Therefore if the port mouth is the only thing changing ant the volume is staying the same then I want to try using the same port area as recommended at 11 inches square and leave the volume as is...I assume that the chamber might be more efficient with a lower area vent but that is just an assumption. I don't have enough room for a conventional size ported volume in my prototype box. I don't have tools and my caregiver made me take down my drawing that I had on graph paper hanging on my closet door... I wanna be free!!! I set money aside for tools then found out I can't even buy tools because my caregivers are responsible if I cut my hand off. LEt me know waht you think about trying to use a port LENGTH of zero... Thanks for your help! |
