Are there any drawbacks to straight horns for kick besides the obvious depth size ?
What free plans are kicking about? Ideally 65-70 to 180-200hz not higher. |

One disadvantage is that you're not going to get the band pass loading beneath the minimum horn loading frequency as dictated by the size of the horn mouth. This means if you want the horn to go as low as BPH cabs like HD15, USB, ES18 etc. you'll need a larger horn mouth.

Also I'm not sure a straight horn is worth the extra depth if you only need to go to 180-200Hz, starts to make more sense if you want to reach 300-350Hz in my (very non-expert) opinion.

That coffin bin thread lost all the pics, annoying.
Yea im aware they wont be a standalone bass solution if it comes to that, that is a compromise im willing to take. So what dictates more the lower cutoff the horn mouth or horn lenght? Darkmatter isnt it other way around ,regarding frequency :) |

The horn length determines the 1/4 wave length resonance, which is often depicted as the lowest the horn will play. This is influenced by other horn parameters though, amongst the horn mouth and throat. If the horn mouth is very large and thus the flare rate of the horn is as well, the horn will appear shorter, on the other hand, if the horn mouth is very small the horn will appear longer. A larger mouth will boost overall efficiency and smoothing things out, a smaller mouth will boost low frequency output, the throat will do the opposite in effect.
The deep cabinet is the main disadvantage of a straight horn, the band pass effect can still be created by adding front chamber volume. This will add more low output in exchange for (you've guessed it by now) limiting the upper band width. Best regards Johan Edited by mobiele eenheid - 12 July 2017 at 9:32pm |

Don't think so... a standard folded horn will likely sound bad playing the higher frequencies. A well designed straight horn should play higher more easily. However the straight horn is likely to be an awkward depth and the HB1505C1 box (for example) has plenty of dead space which could be avoided in a folded layout.

I misunderstood what you said, you mean a straight horn aint worth it at all if just aiming for 180hz upper cutoff...
I just realized theres already lots of threads on this subject actually  Understood Mr. Johan, so without needing the bass extension below 70hz and not a particulary great upper cutoff, would have to aim somewhere in between regarding mouths and throats. |

What about the mkb230? Gets good reviews , I like the idea , using 12's in a horn , one fold rite by the throat !
Personally looking for a 12" or 15" design that's pure horn that gets up to 500 and goes down to around the 90/100 area ,actually cant find anything |
