[QUOTE="shredder2, post: 8682894, member: 674047"] The volume change has worked, I still coil tap around cabin frequency but am able to get closer to 47hz than before. I'm hoping another .5ft3 might get me there. With the volume/tuning change I'll probably clamp more power at that frequency (47hz) so I might be chasing my tail... we'll see. The coil tap starts at 44hz now instead of before the change at 42hz... from a 150.8db to 151.51db with only a small volume (.5ft3) change and consequent tuning change has me wondering if I might get lucky and break 152db with another identical change. Testing, testing... but it's getting hard to shrink the enclosure anymore so I will have to be creative. [IMG]https://i.imgur.com/2NhpXoi.jpg[/IMG] [/QUOTE]
