      What kind of sensitivity boost are you getting compared to a vented enclosure?

      And why is the chamber behind the woofer no longer sealed, and the horn, closed, in the picture above?

        Pete I am going to assume the that is an access panel under the woof and maybe the mouth had not been cut out yet?

        DIY guy, I am very interested in this. I've designed a couple of horns, but am always looking for something to make folding the lines easier.

                  Part 1 helps a lot. The photo and diagrams make a big difference.

                      Really interesting stuff. The more explanation the better! Keep it coming, along with any tips for appropriate drivers for this box type, etc...

                          Why not just seal the box, throw a couple of good 8's, or 10's in there and call it a day.

                          ... My #1 gripe with horns, you can get 90% of the performance out of a much smaller enclosure.

                          Sorry to troll, They have their purpose too, but I am not understanding the application of this...

                              That is so far from the truth you are calling black white and white black.

                              A horn done properly will outperform a vented box. I did a demonstration a while back using four different box types and all the same drivers. The horns won by quite a margin. The horn loaded configuration had dynamics up the ying yang. The vented box held it's own to a degree but not even close when put up against the lower coloration and greater dynamic range of the horn loaded system.

                              A well designed horn has a 10 db advantage over the same driver in a vented box. That is twice as loud acoustically and 6 times as efficient electrically.

                              There is a definite trade off. Larger box, lower distortion in terms of tenths of percent compared to tens of a percent with the same driver in a vented enclosure. Horns sound much more life like. But they are larger. Can't win there.
