I have a Dayton DVC 12" sub in a 85L enclosure and I am not satisfied with it. It seems to struggle with the sub 25hz stuff,it also bottoms out.The amp is a Rythmik A250 basic. I have thought of doing several different things.
I thought about a PR design but I don't think this will do it plus the cost is enough to call it a risk. Since I might not like the sound of a PR'd sub.
While looking into the PR it was suggested by Jack Gilvey to try the 142L adire shiva design. I happen to have a 4" Precision Port already. So I think I will go the sonotube route since the construction should be fairly speedy and cheap.There is one thing that has me concerned and that is after reading thread after thread of similar issues. I have seen it posted more than once that as the enclosure goes up in volume it will be easier(take less power) to bottom out the driver.
So I was checking out adire's site and came across the DVC Subwoofers 101. Where it talks about using one coil to power the sub and shorting the other. It acts as a brake to help cotrol the sub.
If I were to power one coil and short the other on my 12" DVC. My amp would put out 150W@8ohms and this should aid in not bottoming out the driver. Is there a particular drawback(s) to what I am thinking? To sum up a 142L using a full length 4" Flared port powering one coil with the other shorted.
