Hi!
I have a 10 inch infnity servo sub (what does servo sub mean anyway, does it have a motor in it???) and it was designed very poorly by putting a port in it. This makes it very thuddy at volumes not even that loud. So, I want to make it a sealed box. I noticed that when i covered the port partially with my hand, the thudding went away, and it got tighter sounding. Can I just put a piece of 4-inch diameter foam or somthing into the 3-inch port to stop this? If not, what should I do?
Thanks, Mike

The "servo" in its name mean that there is a sensor of some sort feeding back information about the motion of the cone to the amplifier. Than the amp will alter the signal to control the speakers cone for "proper" motion.
It may very well have been poorly designed, but the port is not an indication of this.
Yes, but you will loose the lowest octave of output from the sub.
What I notice is that the cone moves out then sucks in with a boom, then it slowly moves back to normal position (it takes about a second to do this). Since it is moving like that, it makes a thudding distortion sound. If I am right, it has a 600W amp (or draws 600W from the line), so I know that the distortion isn't the amp.
Like I said, when I covered the port, the thud and distortion went away, and the sound was tighter. What do you mean by "you will lose the lowest octave of the sub". Does that mean it won't be able to produce as deep of sounds?
What could be a cause of the cone thudding? Is it just reaching it's max volume (which isn't adding much at all to my B&W speakers)? Is the something wrong with it?
I know that ports mostly pull air into it. Since a sub speker moves a lot of air, I would almost think it would suck the foam into the case??
Thanks for the help, Mike
