with this displacement I have to add cone volume to vtc, instead if it's mounted straight I have to substract all the driver displacement. |

Idiot question:
mounting of the driver in this cab - firing into the chamber (magnet in the 'horn' mouth), or other way round? which is the intended design? |

Hehe!
KenTech, in that case your old HR version should be able to simulate that cab...

bitzo, you are absolutely correct!
Do you think that these volume differences will have a big influence on the frequency response/performance of this cab?
cheers

Thx KenTech, I never tried if the driver would fit reverse mounted...
bitzo, so you will have to subtract the driver volume from vfc.

this is what confused me.
incidentally, im interested here because it looks like a good compact sub for a 12v system - if build it as a 12inch-er. Any recomendation for 12inch driver to get the most bang for my buck - i dont want to make the mistake of inefficient car sub drivers again... |

ibex, very few drivers aren't deep. I haven't tried, but i've measured with Autocad the distance and it seems like you need a driver no deeper than ~16 cm...
that's realy imposible... :) |

hold your horses
theres a new fashion for flat subs - they are only a few inches thick.. http://www.google.co.uk/search?q=flat+sub people with expensive sports cars with nowhere for proper enclosures to go put them behing seats and whatnot.. presumably efficiency is sacraficed... dont really know. they are interesting looking things anyway.. |

so different beasts I think....regarding sims beyma cab drops lower than a bandpass horn but have less kick but more flat under 120 hz. I'm playing around this tapped horn to get more kicky and less subby ;P
