It’s just harder for drivers to push those low frequencies at high volumes. That’s why live events need a wall of subs to get usable levels that low in frequency. The Meyer VLFC is even made just for that very bottom end because regular subs don’t do it well. You can get that low in…Read more

If you follow the recommended Vas from that driver’s spec page of 248 liters and put no filters in you can see that the response in WinISD matches pretty close to the published graph on that spec sheet. Even using the full 1200 watts…Read more

My understanding is that a driver’s response tends to fall off quickly after that number so it might not be the right choice if you’re looking to get to 20Hz.Don’t ignore the cone excursion graph. I missed that on my first one and was…Read more

I probably should have looked at the stock response more and built around that. Is there a part of the spec that gives an idea of what’s required to achieve that? Is Vas related to the box size?

I work in live pro audio so I know things about sound but not the technical aspects of speaker drivers. I watched some videos on WinISD and used Sketchup to plan my box. They were designed as small desktop speakers with a single 4″ driver (Dayton RS100). Playing around with some different…Read more
