| Is there any reason why, as long as I keep the chamber volumes, port areas and port lengths the same why I can't make a wider but shallower version of the X1? |

do you mean wider as in make the ports taller? (NOT deeper, i mean longer on the front of the box)
keeping the chamber volumes the same won't be so easy because of the angled baffle - still won't be too difficult, but will need a bit of working out could also encounter some problems with air noises if the ports get too narrow (to make up for increased port height) making the cabinet longer instead of wider would avoid messing about with the ports, but you'd have to make sure to spread that extra length (and therefore volume) correctly between the chambers. which again, because of the angled baffle, would need some careful thinking. i suppose any excess chamber volume could be dealt with through a couple of extra bits of bracing... good luck |

Longer, wider, it depends which way round you're looking at it.... If the ports are at either end (rather than top and bottom) I mean wider. Keeping port area and length the same as I said to avoid any messing around with ports... The plan is to have a box that will sit under 2 kick bins... |

Late answer: If you leave the port area, length and chamber volume the same, it will give no difference in theory. Sometimes slightly in practice tho, but nothing serious. Keep in mind that the rear of the port (inside) needs to stay away from the back wall. If it comes to close it will effect the portlenght. Cheers |

I had a student at work who posted a lovely moto on the wall: In theory there is no difference between theory and practice, But in practice there is. |

| Which is why I'm happy to build one of each design and run them side by side to see what the difference was, in practice... |

Just a general question about the X1, what kind of sound should I be getting out of the box. Should I be able to feel the bass punch at 10 feet or just here enormous rumbles of bass? I'm using the C18-650EL driven with a QSC 2450. What kind of numbers per stack are needed? 2 or more I'm guessing? I had a chance to hear some EAW sb-1000's and they packed quite a punch at 10-15ft, is the X1 comparable?

I wonder how this new Void driver that is designed specifically for bandpass cabs will sound in the X1

Mal are u using the V-18 1000, and if so how much are you sticking into each x1, where are you x-ing them over? Jez |

Yes, he uses the V18 driver, and runs the 4 cabs off a Network 4, giving 900watts to each driver. I assume they get crossed over at 80hz. |
