http://koti.mbnet.fi/parkerf/1850/1850ext.jpg - http://koti.mbnet.fi/parkerf/1850/1850ext.jpg Something like that with biiig butterfly catches and some heavy bracing of course. I drew that one 115cm long so there could be two 1850s on their side on top of that as a kick bin. I haven't done any calculations, only rough drawing. That thing should add something like one metre of length. |

Been thinking along those lines as well (other cabinet). You could most likely leave the rounding bit, making bracing and building a lot easier/cheaper. From tests so far vibration between cabinets didn't seem so much of a problem, but didn't test with more than 600 W.
It doesn't seem to work on every cabinet tho, sometimes the added length in contrast to the added mouth area is just plain wrong. Definately worth a simulation.

Rog's not here anymore... Check out Walt's modular horn, for something similar. If I'm not mistaken, the B-Zero works with 2 horns as well. ------------- Away on extended leave. |

| Of course it looks large, I believe you couldn't do much smaller 2.5 meter long front loaded horn with a mouth even remotely big enough? The point is it being modular it shouldn't be too hard to move around and if there's no need for extra sub frequencies, the extension could be left in the storage. I'm not capable of modelling the horn (newbie me!) but that sketch can't be far out, if someone is bored enough to try to model it I would be really nice! |

Not an expert, but it'd be worth doing (trying) definately, I've often thought of doing similar myself! Longer horn+bigger mouth = lower FS and higher efficiency as far as I know. It wouldn't cost much to try, and if you have the storage space, what is there to lose? |

Added in the 40 -50 Hz area mostly, 40 Hz + 3-4 dB.
Such a thing is easy simulated in Hornresp.
