Thanks for the input, I'm looking for it and reading it asap. Honestly i've been trying to have some good reading on acoustics/speakerdesign/audio in general, so any input is welcome! |

I also literally submitted 40,000 words, tons of real measurements on scale models and sixty BEM studies on this last week for a master’s degree. It isn’t exactly the same, but until the product of complex wavenumber and equivalent surface radiation impedance are approaching 10, the coverage angles are more or less the same in the pass band of interest. An asymmetrical horn profile does create some aberrations - again, outside of the region you’d use the sub in - but these are caused by diffraction and also apply to a largely asymmetrical ported box too. |

This is simply incorrect.
Stack 1 Twin 18” reflex subs 8 cabs 4.8M x1.2M radiating area 150dB SPL at 1M Stack 2 Single 18” front loaded horns 8 cabs 4.8M x 1.2M radiating area 150dB SPL at 1M Both stacks will offer 132dB at 8M and 120dB at 32M How do horns out “throw “ the reflex cabs exactly?

Did i say "throw"? We were not talking about artillery, were we? What i was talking about is the significant combination of high spl and strong directivity for which horns are generally capable of delivering percievably louder sound at a distance, rather than reflex cabs. |

Did you manage to get any measurements of the siniai paraflex?
I'd be pretty interested in seeing the group delay specifically.

Oh here we go. Good advice followed by oft-repeated bullshit. Throw does not exist. |

You'd better load the 18LW2600 in a reflex cab, since it has been designed for that job. Maybe you can try and see if it works in scoops as well, but it won't sound like a front loaded horn.
If you really need flh for sub duty, then read the threads about 1850, Martin wsx, invader, CV L36, punisher, lab, and so on.. do some research and see what's best for your purposes, just keep in mind there's no "best bass horn" in absolute terms: it's up to what music you'll play, where, the level of spl you need, at what frequency.. and how much money you can spend! I think 4 reflex cabs loaded with the 18LW2600 (well processed and driven by proper amps) would probably give enough deep and loud sub bass to shake belly buttons 10mt away outdoor, with high spl focused on the dancefloor, without being heard miles away (unlike most folded horns), and the cabs would be lighter, cheaper and easier to build. On the other side, with folded horns like 1850 or L36 you'll be quite loud and punchy but you'll need more than 4 cabs stacked together to get deep sub frequencies with decent spl.
