No not asking for the plan  But, given its based on the WSX we can assume long folded horn, but the reflex part interests me. Stasys X has long port path to give the LF extension, but the WLX and WMX just seem to port straight into the rear chamber with fairly short ports. Are they working on a different principle? |

I've had a chance to poke around a WMX. Couldn't take the driver out to see the throat arrangement but it's probably a typical Martin letterbox. Driver faces the corner of the cab but the horn path J shaped. Roughly half the cab is horn, half is reflex rear chamber. |

Ah, so presume from that it does not have the same number of folds in the horn path as the WSX? More importantly, did you hear it in anger and what was the verdict? |

Only one fold, just at the start. The horn length on the WMX is the depth of the box plus the short U-turn. I haven't heard much of them in use, only one per side for a wedding but they seemed to do what they say on the tin! Pretty good for a single box. Oh, and the driver appears to be a B&C, probably an 18PZB100. |

£3k subs at a wedding  Forgive my probable ignorance, didn't much sleep last night, is the U turn also the fold like the first one below (ie effectively a ported band pass horn), or is there another fold before it gets to the bend like the second pic. Also, someone once posted some internal shots of the WLX and it had some small triangular ports on the baffle into the horn throat, did you spot any on the WMX or is it just the ports to the cab front? And Clearly I own at visio  |

Ah, actually it wasn't a wedding, it was a band who when I usually see them they're doing Jewish functions. It was actually a corporate do but same setup.... Sorry, I didn't explain well. The driver faces the other corner and is right up to the rear of the cab. Bit like a HD15 but with the baffle at more of an angle. |

Posted By: ceharden
Date Posted: 14 July 2008 at 2:42pm
|
It's the thick panel on the lower right hand side. Fires through a letterbox, round and out. Very similar to my ported horns really. Tempted to give an 18" version a go, would be the same size as my twin 18" reflex boxes. |

Ah sorry, brain fart - I presume the gap between the baffle and the horn path wall is the port from the chamber into the horn throat, didn't realise it was all the way through though, thought it was a cut out in each corner of the baffle These actually look like a relatively simple build compared to say the WSX, granted not as simple as a reflex but not loads of stupid angle cuts |
Posted By: ceharden
Date Posted: 14 July 2008 at 2:54pm
|
That gap is probably just a way of making use of as much space as possible for the rear chamber. Reflex boxes can get pretty complicated when you start refining the design. These would be nice and easy to build as you say. |

I think i'm getting mixed up on there as to whats panel and whats brace  TDA - is the rear chamber ported into the throat as well as the two ports to the outside world? Will plastic pipe type ports cut it in these cabs or will it need something a bit more sturdy making from wood? |

Posted By: richters
Date Posted: 14 July 2008 at 10:52pm
| Looking at the picture, I would say that's not 18pzb100 because of the 18tbx100 style cone. It's close to the old model from b&c 18tbx46 (looking at the alu frame), maybe it is an oem version of that. |

Ok found the pic i was on about. WMX is 4 ports, 2 internal, 2 external. WLX is 2 external ports only. Which I think makes these cabs quite different beasts. Looking at the WMX a bit closer, its beginning to remind me of the Nexo CD18 a little (obv without the cardiod rear driver) So.... WLX is a ported horn WMX is some weird horn/reflex/bandpass hybrid Looking at Jeff Nine Bars test vid on youtube though if the piece of paper test is anything to go by then the WMX shifts some serious air low down. As does the Nexo, but then the Nexo can't go that high without wallowing. Wonder if Jeff can cast some light on what they sound like in comparison to other cabs (X1 would be the obvious one that springs to mind) |
Posted By: ceharden
Date Posted: 15 July 2008 at 12:12am
|
Are you sure the WMX has internal ports? I couldn't see any when I was looking through the ports into the rear chamber. The Martin website claims it's the same type of loading for both cabs and I've only ever seen ports to the outside on their cabs. Can you show us the picture? |
Posted By: SteveAATW
Date Posted: 15 July 2008 at 12:27am
Sure, courtesy of TDA's photofiles: Unless there's something going on behind the baffle which boxes it all off and encloses the throat there's two triangular ports either side at the bottom - does that look similar to what you saw? |

| I would say that like we were discussing ref. the WLX, there is a letterbox throat and those triangular cut-outs are just to include the otherwise wasted space in the rear chamber. |

That would be naughty 
Plus the accurate drawing is only so much help. The drivers are likely to be off the shelf, but its not 100% certain they are, their could be some voodoo going on. So it's not just a case of copying the dimensions and building a copy. Even if the drawing seems resonable enough you need to drop it into hornresp with the driver params of whatever driver you choose, check the output and do the port tuning manually

I was trying to do the exact thing in horn resp but somehow the graphs dont look like i will like too. It drops like a rock under 40Hz and the excursion is more than 10mm. Maybe i should spend some more time refining the ports and the back chamber volume ------------- Marjan Milosevic MM-Acoustics www.mm-acoustics.com https://www.facebook.com/pages/MM-Acoustics/608901282527713 |

SteveAATW, in reply to your private message on the WMX, though I would post a reply here as everyone can read then..
The WMX are sick bass bins, they move serious amounts of air, they are a short horn with ported rear chamber, they sound lovely, they move air like an 1850 horn/looney bin but sound more musical and go a bit lower. They don't drop like a lab or WSX as the tuning point is prob about 40-45 hz, but certainly have a faster hit.
I'll try and get a picture of the inside next time I have them out.

The best bit is that they're so damn simple! The only bit that Steve and I haven't been able to work out is the exact throat arrangement. Also the hardest to get a picture of unfortunately. |

| the driver fires onto a slotted baffle a bit like a Martin 215. if that make sense? |
Posted By: ceharden
Date Posted: 18 July 2008 at 2:21pm
Yeah, we'd guessed that, more interested in what happens between that and the first fold, and of course the actual throat area 
|
Posted By: minaximal
Date Posted: 18 July 2008 at 2:25pm
|
maybe the wedge next to the throat which looks like it could be ported is actually a helmhotz absorber chamber.. i'v played with this idea before with aj horn, sometimes it can help output, when correctly sized.

To be honest I'm just interested in how the damn thing works than building a million clones of it. Done some variations of my own in horn resp and although you can get a response out of it, its a bit peaky a doesn't drop as low as the martin specs would suggest As Chris mentioned, its simplicity has me intrigued, if it really is as simple as it appears then you wonder why aren't more people doing it |

You will of course have seen that I've already done a ported horn design which works very well indeed from initial testing (still need to get them finished and out on more gigs). That doesn't mean I don't want to know how other people do it for comparison.... The WMX is the wrong shape for me anyway. I like the look of the WLX more, about the same size as one of my twin 18" boxes. Interestingly I can get a nice flat response with a 15" ported horn (measures flat too) but trying to design a sensibly sized 18" version it just comes out really peaky. Tried a few drivers in the simulations and it doesn't make much difference. |

I agree Mykey. No matter how good a clone is - it's still a clone. A martin 215 clone is fine by me (I mean - think of all the free plans that were virtually identical to them released by the driver manufacturers), WSX is pushing it as they are still being actively produced, but a WLX? Plans? TDA - you seem to have a pretty good head and a good set of hands - it's time to put down the measuring tape and take out pen, paper and calculator to use in designing some cabs of your own.
