| the 2x18 manifold on the speakerstore site by Niki Van Den Bosch. what others are there down to 30hz |

In my experience you'll truggle to get a manifold box good to 30hz without it becoming really huge. EV's were only good to 60hz or so. My Beyma one starts rolling off at about 70hz but it is very small ------------- My laser stuff: http://www.facebook.com/SubsonicSystems" rel="nofollow - Frikkin Lasers |

Looks like a EV Deltamax sub. They work quite well. |

 The dml subs work great, IF you have the factory prossesor to run them as they were intended to be used. Ive had alot of experience with deltamax and love the stuff. Having said that, its my belife that these boxes will not preform very well at all without EV specific drivers and prossesors!------------- Keep conventional cabinets alive! |

thats to sort out the shoddy frequency response to make these boxes usable. dont you just love company/box specific processor settings... ------------- Subs + Barges = :) http://www.metaacoustics.com" rel="nofollow - www.metaacoustics.com |

Hi all "Having said that, its my belife that these boxes will not preform very well at all without EV specific drivers and prossesors!" dont worry on my case is the Deltamax clones from SSE will work well whiad DAS G45 but you must use some hi pass filter my case 24db oct set at 35hz and low pass 24db/oct 80hz have fun yours Vitor |

Those manifolds are EV MTL-2, which are also known as DML-models. They have used DL18MTs and EVX-180A/Bs as for drivers. Their frequency range goes from 45-200 Hz (-3dB) and they give a helluva lot of kick! So they're not 30 Hz cabinets, although their impedance graphs show, that the tuning is around 35-37 Hz but a friend of mine measured them and the cone excursion was about the same around 10 Hz region from 30-40 Hz, so 4th order HP from 30-35 Hz is enough. They can be used to about 30 Hz, when you apply around 6-10 dB of boost to around 30-35 Hz.
The idea, that it works only with EV's drivers and setups are totally wrong! The best results people have gotten from those MTL-2s is, when you use RCF L18P300 drivers in them or same kinds of drivers. The EV's drivers are quite lousy if you compare them to others. They have do sound better, if you stack them They will give quite low frequenys (<40 Hz) but you still need some EQing and guite powerful amp to drive them. They are nice cabinets and I'd like to have 4-8 of them too in stacks. Have a look at the originals, with the EVX-180A drivers: http://archives.telex.com/archives/EV/Speakers/EDS/MTL-2B%20 EDS.pdf and here's the DL18MT version: http://archives.telex.com/archives/EV/Speakers/EDS/MTL-2A%20 EDS.pdf |

you should check out the GAE 2 x 18 cabs loaded with RCF 18p300's great cab sorry if some has mentioned these already only i havnt bothered reading the post's ------------- ......just all them hanging there like giant bananas. |

"the Deltamax clones from SSE will work well whiad DAS G45"
I'm very sorry: I heard them loaded with D.A.S and it sounded like sh*t...
"The idea, that it works only with EV's drivers and setups are totally wrong!"
Correct, I use Beyma-drivers and a DCX-2496 and my (8) cabs sound great
 Here you can find some pics:

Bye the way, I know Nikki van den Bosch - he's also from Belgium. He's MTL-2's loaded with Eminence (and also using a DCX-2496) sound great!

| Have used OEM, eminence and p-audio loaded MTL2's. With anything from utradrives, Driveracks to the ev processors. 40Hz - 80 / 85HZ without EQ. Theyre loud and for some reason throw quite far outside. They take plaster off walls in club setups too... f**k them with power though. |

| And I have seen a LOT of half MTL2's that rock parties into jail almost. With normal analogue x-overs. Theyre great boxes. Build them if you want. They can be heavy on yr back though... |

Heres the plan of the 'half MTL2' thats going around here. The get loaded with all sorts of 18's. the most common ones are: Eminence Omega 18's & Kappa 18's P-Audio C18-650's & E18-400s' All depends on yr amplifiers and applications. They all sound gret too. Don't try to model them either. It doesnt work. f**k knows why, but the boxes work... http://imageshack.us/?x=my6&myref=http://www.imageshack.us/">  |

Does anyone have a photograph of the finished item?
Is there another angle to this drawing??

Thats what I got off an emty cab with a tape-measure. Will try and ge a photo of 1 when I see 1 again. If you want a different angle, turn the left-hand side square 90deg to the right and then u have the position the box is supposed to be in when you play it. |

BEST driver for these cabs PD 186, or Orberton, heres what the Manufactures of Oberton have to say ........
We buy the paper cone for our speakers from the same company that supply Electrovoice. For our speakers 18XB700 we use the same cone like EVX 180A speaker. EV use cone with weight 50g I order for our speakers 60g cone from the same Kevlar paper. Our voice coil is 25 mm. instead 20mm. of EVX180A. We have cooling holes under the spider and under the voice coil to reduce power compression. Some customer told me on the Best regards OBERTON Co. ------------- Sticks n Stones |

"BEST driver for these cabsis PD 186 or Orberton 18XB700"
... and this is based on what?
Here in Europe, none of these brands/types are used in the manifold cabs.
Of course I have the designs of the MT-2L but I'm not so willing to give them - I expect something in return: more specific the design of a 3-way topcabinet 15"+10+2"

I have say, that don't use the PD 186, it's not that good of a driver for the cabinet, too low EBP. The best driver in terms of price and quality is still the RCF L18P300, although I'd personally use (if you have the money) RCF LF18X400, that's the one with the Muller cone (the difference between X400 and G400) but the G400 works also the same, 'cause the T/S parameters are the same.
If you want to model it in WinISD, use this setup: 6th order BP, rear enclosure ~170-175 L, front ~80 L, 2 rear ports 14x23 cm by 70 cm in length and front 87x22 cm by 50 cm in length. This gives you a rough estimate of the bass response but upper end extends to about 150-170 Hz with a bit of rising and then cuts off. So with those values you can estimate the response with different drivers. I'd still recommend the RCF L18P300 as the easiest driver available and with a decent price. It's found out in practice that, it's a good drivers for that cabinet, a helluva lot better than the original ones! |

Hi all,
here in Belgium me and my collegues we tried the MT-2L's with several speakers. We had the best result with the RCF 18S800.
Will also do without cabinet-adjustements: RCF 18P300 and Eminence Sigma Pro-18. For the Beyma 18G400 which I used, the ports should be slightly adjusted

If you're going the route of a 10" mid then a 1.4" compression driver will be much sweeter than a 2" unless you spend some serious money. ------------- My laser stuff: http://www.facebook.com/SubsonicSystems" rel="nofollow - Frikkin Lasers |

| ... yes, that can be an option but I'll use the 2"ers first because I already have the mid-speakers (Beyma 10M250) and the drivers (Beyma CP-600TI on a Beyma TD-360 horn) |
