Newbie here. I've built plenty of guitar cabs, but I've been putting together a moderate PA based on EV S100's stacked in a line array. The CD horns actually blend really well and the set up is easy to carry around. But I'm working on compact subs to go with it. Does anyone have the layout for the EV T18's? I have a pair of S181's and another pair of drivers. I'd like to build 4 of the T18 style cabs and swap all the drivers into them. Since I already have the EV drivers, the T18 dimensions would give the correct tuning, as opposed to something like the RTL which I've already found. |

| Thanks, but I've searched this side, and the pro audio lab site, six ways to Sunday and can't find such a diagram. I did find a layout for the 2-18 thing, an MT4 I believe, but not the single driver T18 cab. And the MT4 is not exactly 2 T18's mated together. I could try to reverse engineer the volumes and port lengths, and transfer that to the published exterior dimensions of the T18, but that would be a bear. Any links would be much appreciated. |

No the MT4 is a big 4 driver BP6/manifold beast ------------- My laser stuff: http://www.facebook.com/SubsonicSystems" rel="nofollow - Frikkin Lasers |

Opps, I think I mean an MTL. I have found that EV made something called an Sb180 that has the angled front part of the baffle like the MTL, to make more of a horn than the T18 which just has the speaker mounting surface going all the way to the front of the cabinet. Does anyone know how these compare to the T18's? Are they exactly half an MTL? Thanks. |

I dont know why everyone is wanting to build these.95dB/1watt at 50hz isnt very useful. http://www.electrovoice.com/Electrovoice3/products.nsf/pages/T18 - http://www.electrovoice.com/Electrovoice3/products.nsf/pages /T18 http://www.electrovoice.com/Electrovoice3/files.nsf/Pages/T18/$file/T18-eds.pdf - http://www.electrovoice.com/Electrovoice3/files.nsf/Pages/T1 8/$file/T18-eds.pdf |

| I don't know how EV measure, but if you place a LP mid-band you end up with a nice over-all transfer function suitable for live-music. Not too many BR subwoofers measure 95dB@50hz in case you were wondering (especially not under power) |

EV's measurements are interesting...The eliminator sub says -3db points at 40hz and 100hz(+/-3db) yet 40hz is 20db below the max sens at 65hz and 100hz is 4db below the peak. Doesn't look right to me(16db is NOT +/-3db)

Yep but whats the point unless you get the T18 cheap,its just gimicky.That sharp peak in output looks horrible! BR can achieve about 1dB sensitivity less than that. I just dont see any real advantages. |

I see that I would get a smoother response with a bass reflex. And I understand that they couple to the floor in small rooms well. But I want something small that I can still use outdoors and has some throw. The s181 cabs I have now are okay in small rooms, but less efficient than the T18 and have no throw at all the speak of. It seems like the T18's are a good compromise between a br and larger full blown horn. I will need to hear the subs in small rooms on occasion, and don't want something that takes fifty feet to develop, or requires buying a big truck to haul around. |

I will add that although they do have wierd response,they do sound good
with live music. There is a pub in Fremantle West Aus that until about
2 months ago used 2 a side under dual 12" ev's(dunno which ones). They
were rather nice actually and output wasn't a problem. Maybe another case of odd response and high distortion actually 'sounding' nice to the human ear? ------------- Speaker addict |
