Hello I am trying to find some info on the 18 sound duel 18 reflex cabs. These ones, http://www.eighteensound.com/media/W1siZiIsIjIwMTgvMTAvMjMvMTFfNDBfMDVfMjI0XzE4c291bmRfMThfZHVhbF9zdWJ3b29mZXJfa2l0LnBkZiJdXQ?fbclid=IwAR0m69irBv6B2tFz3Cz_t0RMhngSS_4Si3QWDUQIxcvpAlNrCqyCASEhhy8
Would PD1852 drivers work in them? Is there a way to determine which drivers would work? Do they work best with kicks above them? Many thanks

erm, why would you use the "wrong" drivers in a suggested/tried and tested design? the way to determine options is educated simulations any sub might work "best" with "kicks" depending on your specific requirements |

Well, because I don't know they are the "wrong" drivers. That's why I'm asking. Mental, right?
I have some 1852s I could use and I could source this box with a little effort so I'm wondering if I should make the effort.
Educated simulations, ok thanks mate. As I said I'm trying to find some info so I don't have to ask stupid questions any more. I thought learning was what this place was about. I don't know much about the box, is it sub only usually or does it play nice up to 180hz or thereabouts and so wouldn't require a dedicated kick box? |

not meant to come across rude by any means.. imho, no low tuned cab would do "180hz" well on its own, its just not possible physically.. (at least thats what i have experienced the last 15years) so you are looking for the best option to use the 1852s you got already? |

Yes, that's right, i am thinking how best to use 1852s. But those cabs are available so I thought it was worth investigating.
Indoor use. I've a few options with loaded kick bins I could put together, so that's why I wondered if these cabs are usually used together with kicks. Many thanks |

That design is supplied by 18 sound to suit one of the drivers they manufacture. Its out there to help sales a little i guess. If you read the enclose design document it lists the driver its designed for.
Its possible to simulate reflex cabinets in WINisd. You'll need to look up the thiele small parameters for your drive and read the winisd help files. Takes a little patience, but once you do it you will understand the trade offs much better. You could then either modify this design or make your own from scratch What tops are you using? Music type? Crowd size? Indoor / Outdoor? All those questions should help people narrow down the advice they give you. |

1852s should work well in rather compact reflex cabs, according to stated specs/tsp, they are a bit weird spec wise though imo.. plenty of motor power (BL), cones/suspension are too light ( high fs) for low low tuning though, seems "ideal" for large flhs and bphs - one way bass options, covering 40ish to 120ish hz.. |

Right ok, thanks. I had a look at the thiele small parameters and some matched 1852 and others were only a little off from their suggested driver. That was an encouraging start, I thought.
I'd use Mt102. Indoor Eventually, 2 stacks, 4 PD1852 per side No specific music type really but it'd be nice to have some flexibility Ideally it'd be able to cover a few 100 people. At this point though, i've simply got an opportunity to use these drivers with 18sound BR (also maybe an 18sound duel BPH) so i was curious if anyone thought it might work or could point me to some more info on the box. It is quite difficult to search for these boxes in the forum search. At least im struggling to find info so far.

with mt102s covering 200ish hz up you`d need "kicks" anyways to close the gap imo.. |

Did you just buy these drivers? PD says they are suitable to a wide range of enclosures but in reality they aren't that suitable to BR, they would "work" in a small enclosure but they don't produce much output.. actual in box sensitivity is 96dB below 100hz so a pair of them won't even make 130dB at rated power.
The 18 sound design is way to big for these drivers, over twice as big as it needs to be. My suggestions are either sell these drivers and buy something better suited to BR enclosures or find a horn design of some type that these can be used in.

Thanks for this.
No i didn't just buy them, they have come out of another box (not sure which). I think i will take the advise of trying to sim and seeing if i can come up with a box. And hopefully have some fun. I think i read somewhere that someone was using these drivers in large scoops. Maybe super scoop or polar bear. There doesn't seem to be a lot of write ups on them. That i've found at least. Many thanks
