Fortunately, their fidelity is such that they can still be used for purposes other than pro sound. John Interesting fact that was! The original set consisted of x8 JBL I prefer cloth ribbon its far more robust over foam. Ya think!? If I remember correctly it was 8 cu ft tuned to 30 Hz. At some point JBL changed the tuning frequency of these boxes to 25 Hz. The H became available and it could handle all the power and abuse the original H could not. The H is designed to be used in larger numbers where mutual coupling fills in the VLF region very nicely.

The 25 Hz tuning frequency of the newer S1S and boxes are functionally equivalent to the old B box. You can get more LF extension in a box half the size of the and never worry about "overexcursion" or foam rot. I know, it seems as if you are repeating such things over and over again, and I guess in some ways, you are! But, it is much appreciated, in any case.

I rather liken LH to my stove collecting site, on which I am heading for 7, posts, not too long from now. But, I have to remember that, to a new person, this rather simple and mundane task is extremely daunting, and quite scary!!

If a mistake is made, not only will the stove malfunction, but severe injury, conflagration, and even DEATH, can result!!! Without new folks learning about them, our old, and very "obsolete" backpacking and expedition stoves will slip even further into the collective unconscienceness of history, and before too long, nobody will know a thing about them.

I have alway sat down with some rudimentary test gear, my calculator, a pencil, and some paper, and worked out the alignments as best I could.

Hey, most of the time, they came out fairly well, to tell the truth!! But, all this computer modeling is new, and somewhat scary to me, especially when I see something different, depending on which program is doing the work for you!! Fair enough?! Even if you think otherwise, I AM learning from your wise counsel, and hope to end up with something good when I am finally finished with these projects! Take care, and God Bless! Every Good Wish,.

Click to expand This kind of statistic is very useful for midrange and HF drivers, which are often used for several decades and so a free air measurement of their midband sensitivity corresponds well to real world performance. Subwoofers are somewhat unique in that operation for even two octaves is relatively rare, so it is better to look elsewhere for performance comparisons. It is very important to look at subwoofers as more than a discrete driver, since every application marries a subwoofer with a box, and the two form an integral system. Modern sub woofers are over-damped, with a Qts in the range of 0.
