Hey.. I will se wich driver i can use in the 1850 cabinet. but to do that i need the correct data of the 1850 cabinet to Hornresp, to calculate the frequency. Can somebody take a screenshot of Hornresp with 1850 data? So i can get started. Greetings Steven |

I have entered exactly thesame on my input screen and I get this: ------------- "If brute force doesn't work, you're just not using enough!" |

i get the same thing as djyve.....I have a feeling it's because you messed with the Pmax slider.....if I'm not mistaken, once you enter a value for Pmax, the SPL response graph will show power-limited SPL response I tried simulating 4 cabs in a series-parallel configuration to maintain the same input power, and the graph looks a whole lot closer to the one Rog has in the Plans page...slight humps at ~50Hz and ~100Hz yup I see it now.....after you hit "Calculate" you went under Tools->Maximum SPL and set Maximum Driver Input Power to 1W and set Xmax to 11.3mm....this effectively tells the program that the speaker being simulated can only handle ONE watt of power (which is incorrect), and calculates the maximum possible SPL given the Xmax that was entered....this is why your SPL graph shows "Pmax 1W Xmax 11,3mm" at the top, and also the reason the response is plotted incorrectly |

These input data of 1850 are correct? And another, because the dimensions of the HD1850 are 63.6 x 75 x 95.6 (http://www.speakerplans.com/index.php?id=1850horn) = 456.012 liters. if the simulation of 520.275??  Look:  Someone has input data which coincides with the plant's HD 1850 ????  Thanks |

Horn path is about 165-170cm long.
------------- Support the scoop technology, larger mouth plays louder! |

I am pretty sure that sim is taking the phantom horn into consideration. ------------- A proper build subwoofer will be the only thing in a room that is not shaking. |
