The Mouth Area : 47084 cm2 The Throat Area: 218.18 cm2 Compression Chamber Volume : 11.95 liters Horn Lenght : 17.2 m |

I assume it's a 20hz horn...

If it sounds like a gorilla is trying to escape, turn it down.

You want a quarter of that....
And 20 is REALLY super super low, your amps will stay nice and warm at those frequencies too. Aim for 40ish and let the roll off of more then one horn do the rest for you Edited by mini-mad - 13 March 2018 at 10:08pm |

Corner should get you ABOUT an extra 6dB worth of extra oomph!... and will help with the bottom end too.
It's never gonna be bang on as things in the room can absorb the sound and standing waves in the room won't help either but as I said aim for more like 40hz. It will bring down the size of the box/horn quite a lot. This for home hifi, car or PA? |

6dB boost is for corner loading a reflex. Horn efficiency boost for corner loading is much greater. Same as stacking horns vs stacking reflex.
