Any benefit to splitting the output of a speaker in half?

im looking at this and wondering if it has any real world benefits?

Loading is more symmetrical on both sides of the cone, perhaps reducing distortion compared to an offset style loading.

Some drivers are not “tough enough” for horn loading, the difference would be more apparent with a less rigid cone.

Most designers abandoned “W” type designs and use spiral folding to achieve longer path lengths in similar cabinet volume with less wood, weight, and complexity.

Path length is much shorter per cabinet volume, so low corner is higher with this type of cabinet than one using a single path.

so the above means,

modern spiral loading horn designs *get lower with more authority* then old school W designs ?

art... that's stipe's 45hz tapped horn.... It's a recent design....

Spiral horn designs have been around a lot longer than "W" shaped designs, think of conch shells, tubas and the Edison Victrola.

Since electronic amplification got into the sound picture, and lower FCs have been pursued, various folding schemes have been used. The W bin is but one of the many.

Given the same driver, mouth and throat size, a longer horn goes lower and louder.

Given the same cabinet volume and mouth size, the longer horn will go lower, but the shorter horn will be louder down to Fc (horn cutoff).

Put them in multiples, the longer horn will gain more down low compared to the shorter horn with a higher FC.

Translate that in to terms of "authority" however you want .
