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. |

i think i ll go with l18p300 and wsx...i saw specs comparing 18lw2600 and rcf and this is better..i was wrong with all

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.

Imho sbh is absolutely NOT the best bass horn design, on the contrary it can be one of the worst bass horns one can choose to build. It's massive, heavy as f***, tricky and expensive to build.. and the results doesn't pay back: it has a really uneven response, a big dip at 50hz (where most dance music basslines hit) that gets a bit better only with more than 6/8 cabs per stack.. it seems the designer tried to reach lower frequencies, but sacrifying the overall performance. No surprise they're mostly used in freepartyies, where sometimes sound quality isn't the primary goal, and even there most skilled crews get rid of them after some time. I wouldn't even compare it with the CV L36, which is an old commercial product but definitely performs better in its range (Cerwin Vega is STILL working on that old design for their cabs).
To be brutally honest, i understand you like the look of them, but speakers are made for hears, not for eyes.. well, even the back plays a big part ![]() Edited by sushi - 29 November 2021 at 1:23pm |

How many have you listened to? Or measured? It’s your money, wood and time, but myself and others would be looking elsewhere. The Skram has very detailed plans here: https://data-bass.ipbhost.com/topic/742-riccis-skram-subwoofer-files/ And it's quite forgiving on driver choice. Not technically a horn, but very optimised. Hornresp 'max SPL' plots are not trustworthy in general - it's a linear acoustics model, and has no idea about distortion thresholds or cone load - but here's an example of the response shape of various drivers at their Xmax limit: ![]() Hornresp inputs are: ![]() But make sure to use the complex semi inductance model. Click Le so it goes green, and put the data in, Google it for a guide on finding it from TS parameters. |
