I also just rememberd it being the favourite for DJ Judge Jules
 
if your skilled with wood, then the WSX is what you need for outdoors
but the GAE cab is an alrounder, in and outdoors

He is in Trinidad so I do not think GAE is readily available. There are some great cabinet builders there in TNT, EAW 850 copies can be easily obtained.

18p300 is the standard original driver for the wsx, so if you can they may be the right box...

Definitely vote for WSX over KF850 sub!

I would also vote for the WSX as it can give the boom for outdoor use.

Hey, since one EAW SB850 has 2 18" would it sound louder than one WSX which has one 18"? Just askin cause I have no experience with the WSX, Only the EAW. Size for output, the EAW sounds mighty fine, but u got 2 use two drivers, whereas the WSX HAS ONE. iDEAS?

You wont get sub that is extremely loud and throws extremely far with only 2x 18" drivers. LOL

And I hope you have at least 800W rms of amp power for each driver.

L18P300 will self destruct in scoops without much power being supplied.

WSX will sound good outdoors if you have about min 4x of them per stack, and are >=20 meters away from the cabs.

1x L18 loaded, 2x18 reflex will sound good in very, very small venue.

186 Horn/Cerwin Vega SL36 would probably be best all rounder for this driver.

well i do plan to invest in sum more 18's. The RCF are easy to obtain in The Caribbean.
So which is it, the 186 or the WSX?

Get more 18" woofers partner. Pick what is convenient and solid for your use,listen to other systems that are doing what you are planing(not just Davey Scorpion).

To be quite honest, the absolute best thing for you to do is sell the RCF's and get Void V18-1000.

Then you can build either Superscoops, my scoop or WSX, and get extreme SPL with just 4x cabs inside or out. As long as you have min 800W per driver.

It sounds like WSX is it. There is something slightly bigger on http://www.speakerstore.nl/index.php?l=nl&pg=11&c=18 - http://www.speakerstore.nl/index.php?l=nl&pg=11&c=18
Havent heard of anyone building it though.

I know WSX with V18-1000 is immaculate outside, but in small venues indoors with L18P300 I think it might be a bit tame.

Can you borrow a Vega SL36 off someone? May be suprising with L18P300. Will drop deeper than 186 Horn, but larger.

If you then build SL36, it will sound better than an  original.

I'm guessing you are a cab builder, which is good.

On paper well built CVSL36/AB36 should perform better than 186 Horn, and lots of people Worldwide are using Top drivers in CV clones and are very happy. However, the designer of 186 horn says, L18P300 is one of recommended drivers.

I would suggest you build 1x Cerwin Vega SL36 and 1x 186 Horn, maybe out of MDF or Chipboard and try driver in each one, and see which you prefer. (I personally would go for SL36, but its not my money).

There are plans for the CV SL36 around this site somewhere. Strongly recommended you use metal front plate, so it heat sinks speaker chamber like CV Afterburner AB36.

Whatever you do, * DONT * build the Junior versions of the Vega bins.

EDIT: Found these.

AB36

Actually I don't really know. As I said, its drawn of the dodgy gif on their site. There is a panel that you see in this plan thats there so I take it that the woofer plays through a oval-ish hole, because it ends up dead center when you model the woofer between that panel and the brace. This is the 'revised' drawing.... So, I'm guessing its about correct. Best will be is to find 1 and look for yourself.

This is how I think it should look from above

The CV AB36 is improved SL36 plan. Just that AB36 has metal front plate to lower compression by heat sinking... I think....

SL36 plan

Yes but without V18-1000, its not really worth the hassle I think.

Be informed that Lalo made his own designs in the eaw subs to suit 1000 watts rms drivers so when you stood in front of 1 sb850 you was getting slammed with 2000 watts rms of rock solid bass...cheers but then again LALO was and always be a legend in trini.

Ok, well lets analyse the statement then.
 
1) Lalo did not 'design' anything, he just scaled down, and played with the box tuning, all by ear, he did not use box building design/programs for proper analysis, nor did he use the T/S parameters to do what he did. Also, one cannot 'make' design in EAW subs (thats like sayin "I made a mercedes benz"). All EAW designs are proprietary and cannot be changed or else it would not be EAW anymore, it will be something a guy tried and sounded good.
 
2) An original EAW SB850 sub use to contain two RCF L18P300 18" drivers. If u look at the specs on the RCF website it will tell you that the driver is 1000watts. This meant that each EAW SB850 had the potential to put out 2000watts (IF U HAD ENOUGH POWER). Nothing new by Lalo.
 
3) The design of an enclosure doesnt determine its power output, it is a combination of factors, mainly amplifier output. So basically a new design with the same drivers will not give more power. If ur talking DB level, thats different.
 
4) The thing that 'slams' you in front a box is not power bro. It is the decibel level. This is dynamic and its level cannot determined by ear.
 
All in all I still think Lalo will always be a legend in Trinidad for his contribution to the Sound System Industry. Lalo did not earn his name by making boxes, he did it by contributing to the industries needs (doing lots of gigs), always had cutting edge equipment, and knew some of the technicalities of sound system engineering.
 
In Trinidad, Sound System is all about money, cause equipment so expensive here. If u have plenty to spend, u can buy the best and sound great, as long as you have an ear for music and a little technical knowledge. I personally know alot of good sound guys, its just that they cannot afford good equipment.
 
'Cheers'

In trinidad no one cares about thiele parameters most dj wants something loud and sounding good, because of expensive equipment most highly recommend sound barrier and zebra, though i tend to stay as far away from those but i did see a stack of lalo's "trapeziod" bass back in 2005 and that's what he told me, maybe i was misinformed. Anyway what enclosure would you recommend for the 18 sound lw1400 18 inch loudspeaker.

Well first of all, to say "no one cares about thiele parameters" and then refer to "dj" IS TOTALLY wrong. A DJ is not a sound technician, and only knows how to play songs and scratch. A genuine boxbuilder knows about T/S parameters and cares how it is used. Also to say that "in Trinidad no one cares" is unfair too.
 
I am a trinidadian and and a good few fellow Sound technicians do care about our boxes specifications more particularly, Theile Small parameters. I dont have experience with the 18 sound lw1400 so I cannot recommend an enclosure.
 
Oh yeah, and most DJ's dont "recommend Zebra and Sound Barrier" eh. Well at least the professionals I know dont recommend them and dont use them. Yuh makin Trinidad look bad man. Talk to ppl who know their stuff nah.

Its been a while, but I ended up just buying some home built EAW SB850's and loaded them. Happy with the sound.
 
I also got four super scoops loaded with RCF L18 P300 (on a deal). They sound pretty loud IMHO. Even though I read that they are not supposed to be used in horn loaded designs.

gae single or double is a bog standard reflex box, fairly low tuned.
nothing magic going on, simple to design your own version using online calculators and a little reading on BR cabinets in general :)
