A dealer local to me is starting to sell come cabs very like HD`s It has two main differences.   1 There is no compression area.The curved piece just butts upto the driver baffle.
2. the back brace is curved.
Will they work without this compression area, is it essential?
Does the curved section (as opposed to straight) do much good?
They werent loaded when i saw them so couldnt have a listen. Gonna pop in with some pd1550`s and see what the sound like.

the curved reflector makes no difference. ommiting the piece of wood which gives seperated the throat volume from the start of the horn DOES and WILL make a big difference. i'm guessing it wont go as as low or sound as good ------------- Minirig portable soundsystem movement |

| I theory it won't go as low but it should also perform better higher up. Might make it more of an 80Hz upwards kick bin rather than a 60Hz and up cab. |

does it not turn a band pass into a horn - a very short horn at that?

Looks definetly like it will go louder, throw further, with reduced sub. Taken away BP and made a full FLH he has. Increase rear chamber to lower response. ------------- "Who am I? I'm the guy who does his job.. You must be the other guy". |

By removing the front chamber he's made it into a single fold offset driver horn. You can model this on hornresp if you wish, there's a tool for it. ------------- Away on extended leave. |

looking at the other cabs in the "range" it looks like they use Celestion drivers. ------------- http://www.freespeakerplans.com" rel="nofollow - www.freespeakerplans.com |

Dont think they are Celestion. I was shown a couple of `their` drivers. 15" + 18". Looked very much like unbranded chinese. Cast chassis if i remember correctly |

has no one noticed exactly who the seller is?

Yes.........They do sell some sh*te. They are fine for odd bits and bobs in an emergency (they are only round the corner from me).
These are probably a step up from the piezo / skytronic / generic crap they sell.

seems an odd product to rip off/push as it really isn't suited to the cheapo DJ setup. What are you gonna achieve with a couple of these - certainly not earth rumbling bass  "these cabinets provide an ideal, all in one, flexible solution to your audio requirements." Well so long as you have another 3 ways to go with it! ------------- Out to lunch... stableaudio@hotmail.co.uk www.stableaudio.co.uk Speaker Building Services |

Hello, i'm precisely interested in reproducing the 80hz-250hz range, since i have C-subs below 80hz and R2Sh above 250hz: ommiting the piece of wood which gives separated the throat volume from the start of the horn is maybe a bit radical, but would it be an idea to reduce its depth by half in order to do such frequency range ? |
