What are all the drivers suitable for the super scooper 18 as I probably can't afford the PD1850[but I'll see when I sold my other bass bins] Thinking of using Fane Collossus 18B or 18B-600 or XB or Eminence Sigma Pro or Emega Pro,or Celestion Frontline 18.Or Eminence Kappa 18 if I don't get much for my bass bins. |
. PD186 hopefully otherwise I'll use something cheaper.

We've used PD1850 and PD186 and are happy with both. In fact I'd probably struggle to tell you what drivers are in which cabs at the moment.... Why not spend the £220 you were going to spend on a load of eminence 12"s on some decent drivers for once??? ------------- "It sounded like a million fire engines chasing ten million ambulances through a war zone and it was played at a volume that made the empty chair beside me bleed." |

Yes but I do not have £600 or so quid at the moment. £220 would buy me only 1 PD1850 and then I still would have to get the other driver, plywood etc. Got very limited cash of £150 at the moment, and hope to have a few more hundred when I sell the bass bins. |

Well what factors do I need to look for when using drivers in scoops, that way I can buy a driver to suit my budget! So what is the min x max a driver in a scoop should have? Also should the BL be over 20 and the QTS below 0.30 for scoops??? And I read the FAQ and it says horns should use drivers with an EPB over 130. Is the Super Scooper 18 a proper horn or a horn assisted bandpass????

I'm not so sure, the 186 horn says you can use a RCF L18P300 which has an EBP of 89, the PD186 is lower I believe, so I guess its not the case. The scoops in the eminence speaker manual suggests using kappa pro/sigma pro or omega pro 18's which all have EBP's under 130. the sigma pro has an EBP of 112 the omega pro has an EBP of 93 |

So I could use Kappa Pro 15LF in 15 inch scoops, Sigma Pro 18 or Omega Pro 18 in the super scoopers??? Think I'm gonna save up for 2x PD186 instead, not too fond of using eminence for abusive[EQed/subharmonic snyth and pushed] [but non clipped] use. |

If the PD 186 works in a scoop then the void v18 600 will probably also and its cheaper than a 186 maybe call alex at pap and ask Stu ------------- All you need to know is: Sensitivity + Power Handling - Power Compression = Max Output My acts: www.myspace.com/thebowiexperience www.myspace.com/scheisseelektronisches |

A scoop is a horn without the sealed rear chamber. It requires different parameters for this reason. This driver will work better in a scoop than your typical low Qts driver will. http://www.partsexpress.com/pe/pshowdetl.cfm?&DID=7&Partnumber=290-398 - http://www.partsexpress.com/pe/pshowdetl.cfm?&DID=7& Partnumber=290-398
Another driver that looks good for a scoop. ------------- djk |

| A Qts of 0.98 suitable for a Scoop? More like the boot of a car. |

err,isnt 3/4 inch 19mm? how can you get a low vd with 19mm xmax? or
even 9.5mm each way(not sure how this one's measured)on a 21" driver!
Qts though is definately on the far too high side,I've seen 8" twin
cone in roof jobs with qts the same!

The reason precision devices are so expensive is because they are GOOD!!!! However I too think they are overpriced. Dom uses the PD186 in his scoops so go on the precision devices website http://www.papl.co.uk - www.papl.co.uk and look at the T/S parameters and then find one with similar and should work ok Stu ------------- All you need to know is: Sensitivity + Power Handling - Power Compression = Max Output My acts: www.myspace.com/thebowiexperience www.myspace.com/scheisseelektronisches |

Oh yes and you might want to look at these scoops also http://groups.msn.com/SpeakerBuildingpics/shoebox.msnw?action=ShowPhoto&PhotoID=18 - http://groups.msn.com/SpeakerBuildingpics/shoebox.msnw?actio n=ShowPhoto&PhotoID=18 They are for 15" drivers. Im not sure of the recommended drivers but im sure staiper can tell you if you send him a PM Stu ------------- All you need to know is: Sensitivity + Power Handling - Power Compression = Max Output My acts: www.myspace.com/thebowiexperience www.myspace.com/scheisseelektronisches |

| P.Audio C15-650EL. The C18-650EL and the Emmi Omega (I think) are also suitable for horn-loading. |

in terms of bang for buck the fane 18 xb has a long history of usage in
dub and reggae sound's scoops. i think that they have a lovely rich and warm tone, and have heard others say the same. if i was to build scoops now though staiper's 15s would be the ones. james. |

PD might be expensive because they dont pay their workers in thailand 2cents per hour.. Note that when Ive modeled front loaded rear sealed horns,these drivers DONT work well on scoops-the reponse turns into a rippley mess,meaning its not well matched to the horn. Instead I used MLUTIL and found driver which instead provides its own damping by its suspension(spider) on AA 'GM' posted the ideal driver for a old bassmaxx/scoop cabinet.
Are the t/s specs similar to the driver used in the superscooper?

You never know til you model it.ive seen kicker 15"s with Qts 0.7 look fine and nonresonant in HORNRESP. |

Date Posted: 06 June 2005 at 4:04am
| It's all about the motor strength for bass horns (the other parameters are nice for HF extension or findign an optimum) but I wouldn't expect a kicker driver to hold it's motor strength linearily for too much excursion and mike will well know what happens when you model up a Motor strength <5 (using square root formula) in most bass horns. |

To be honest, I put 4 superscoopers in a club, 2 have PD186s in and went into one room, 2 have PD1850s and went into another room, people have moved the cabs about and I'd be hard pushed to tell you which cab is which these days. 1850s and 186s are pretty different drivers... Perhaps I'm just going deaf though. ------------- "It sounded like a million fire engines chasing ten million ambulances through a war zone and it was played at a volume that made the empty chair beside me bleed." |

True,the large signal character is interesting.Couldnt the underhung high excursion hold its crappily low BL for more excursion than a overhung 5mm xmax,25mm xmech prosound type. Just use a notch filter at Fc |

im soon going to build 18" scoops, for the first time. i have two omega pro eminence 18". what happen if i put these eminence drivers in the 18" super scooper? because super scoopers are made for precision devives. do you think its better to build scoops as plans in the eminence manual? |

i repost.... please, what would be the difference if i put eminence omega pro 18" drivers instead of pd1850 in those 18" superscoopers? thanx, mat |

Built my scoops from Rog's plans,Omega Pro's sound good in pretty in them. |

| Just to add to the above.I have another scoop with a 600w Celestion driver in it,don't know model no. but that also sounds ok. |

Probably Celestion Frontline 18 perhaps?? |

what do u think about the fane colossos 18B 600 watts, has a qts of 0,23, the xb has 0.38 and same watts. i always hear, lower qts is always better in scoops...? |

| fane 18xb's sound the business in scoops i havent heard the diff between them and the 18b - but i alwayz think if you know something works -why change it- i would stick with the 18xb's, they are ideal in scoops, i bought some scoops with 18xb's fitted i used them for 3 years without any problems-when i took them out of the scoop- they were dated 1995!! without any signs of any problems or reconing! i do highly recomend them- |
