i have a void v18 1000 but its in the x1

or does someone know a suitable driver ?

No i wanna put other drivers in it, instead of the jbl's.
If i put PD.1850 or void acoustics v18, what would it sound like?

The W18 Keele box was designed for the JBL K151.

The back volume is about 5 cu ft tuned to 35hz.

Look for a driver with specs similar to these:

Qts=0.3

Fs=35hz

Vas=12 cu ft

the wbin was a failure thats why it was discontinued so quickley i knew a fellow that had 48 of these mistakes , but if you want you can load them with the 2241 or gauss 18

It helps to have the correct driver, and not overdrive them.

Interestingly,that photo is almost  identical to the Court acoustics 18" port-assisted w-bin,produced around the same time,early 1980's i think?
Court loaded theirs with the 2240.

2240?

I guess it would work.
 
2241?
 
Vas too high, Qts too high.
 
The 2242 would be a much better choice.

That's a bit strong. Literally thousands of these were made by JBL, SA(Holland) and countless others. The Keele W box was, for its time, quite efficient. Me and my mates still have an old W/Court/4512 rig and we still use it sometimes.

We also have them loaded with 2240. I think if you load it with an 1850, you would start to have to reinforce the bracing. With a 2240 at high power the box colours the sound a lot already, big horn honk, can only imagine what would happen with an 1850.

Edit: Maybe a fresh calculation of the ports would help for an 1850.

"2241 doesnt work in wbin"
 
It doesn't work in THIS W-bin, the back volume is way too small.

the 2241 was built to take over from the 2240 as a direct replacement, i had quite a few jbl factory built orignals boxes that jbl sent me the replacement speakers and they were the 2241, so your saying that jbl dont know their own speakers . the 2240 was rated at 400 watts and the 2241 600 watts

jbl probably sent the 2241 because the 2240 is out of production.but they have different parameters so they cant be the same.noone,here,said"jbl dont know their own speakers"..but if you ask for 2240 and its not available anymore they have to sell something else.its normal..2240 and 2241 are both 600w continuos.

"the 2241 was built to take over from the 2240 as a direct replacement"
 
Only in the sense that they were both 18" in diameter.
 
They are very different speakers otherwise.
 
If you want to use it in this box, go ahead, it will still make lots of noise.

jbl 2240 was rated at 300 watts pink noise and the 2241 600watts pink noise on the jbl spec sheet for the 2241 it says replacement with little or no box retuning need well thats from jbl i guess you know more

"i guess you know more "
 
I certainly do!
 
JBL sells the same software I use.
 
Get some education and learn how to use the software yourself.

i guess you did not understand what i was saying jbl sends a leaflet with the speaker and on it it says replacement with little or no box retuning need thats what i have been saying nothing else, yes the xmas is different and so on, but jbl them self say it is a replacement for the 2240  and it is a more power rated speaker as well not the same power ratings

I don't care what they say, it is not a suitable replacement for the 2240 or 2442 in this cabinet.
 
If you want to believe it, fine.

I recently noticed P.Audio do a P180/2241 driver (and a P180/2242) are these supposed to be JBL equivalents? The P180/2241 has Fs=33Hz, Qts=0.3, Vas=311, which I think is pretty close to djk's recommended pars for a suitable driver

If the reflex is blocked i think the rear chamber volume doesn't matter as much? -Since it is now a front loaded horn? I have two "DAS" boxes like that and they sound very good and clean, but my reflex 4518 copies with fane xb / b600 doesn't sound as good.

Of course they wont play as deep; from 60hz, which is fine for kick-bins wich is what i consider using them for:

subs: 4 CV L48 "E" type earthquake
kick: 4 "W" bins with vents blocked
kick: 8 4512 with phl 15" or beyma g300 or other
midle: 4 12" horns
high: 6 L&R audio 2" horns.

Wonder how thats going to sound? PLENTY of 100hz ability, but maybe weak in mid and mid/high?

how did the jbl wbin sound with that woofer

I'm soon to come into possession of 4 W bins, although their exact spec's I could not say. If it helps they have a single port. Are blue and have been kicking around the bristol scene for quite some time. Reportedly about 17 years old.

They are loaded with 186's and sound nice. For the sake of future advancement of my rig, I was wandering if, on a generic level, two 18" Wbins would sound okay using void v18's as a stop gap before placing the v18's into some hog's I plan to build in the future? I appreciate I might not be able to run them as low, but If I ran them more like low kick's (lower cutoff of say 50?) does anyone know if they would perform okay?

Had the mis-fortune to work in a club in Ibiza (Summum) for a month where thay had these.
Honky bass, and thats being kind. Above were 2x15 JBL, then a 2" on lense, then bullets.
Old school to say the least, I never got much out of the W bins, seem to remember tuning the 2x15 to go as low as possible when owner was out.

Yes i have uesd them and sound good with 186, work well over scoop as kick but a bit heavy.got 4 of them.for sale unloaded

I use a pair of 18" wbins on my rig.

Really pokey things! Drop low enough and throw far enough!

Cross them at 111hz and theyre not honky or anything.
I love them! 

**Edit: Mine aren't ported though, sealed enclosure at the back of the driver...**

Yeah sweet, got your pm. Nice to know they sound good with 186's as that's what I have two of them loaded as. Are your's the above model or are they different? Mine are 18"wbins, although they only have a single port at the front. Most models I've seen have either 2 or 3. Can anyone shed any light as to what make they might be?

What scoops did you have them over? Hogs?

Was intending to use them as kicks in the long run, although might have to force a couple to be subs for about half a year until funds allow hogs to be made. (Hence wanting to know their capabilities with v18's or pd1850's)

Sick, this is always good to hear about thing's you've bought. What difference does having the port sealed make? Have you been able to compare like for like at all?

Don't know, you can calculate the ports to be tuned just below the cutoff of the horn or just block them for clean flh, remember lowcut or waste energy & driver life.
I suggest lowcuts something like this:
8 pcs a side: 40 hz
4 pcs a side: 45hz
2 pcs a side 50 hz
1 pcs 60 hz

Sorry, still learning the ropes a bit here, could you explain what you mean?

Do you mean to make sure that I apply a lower cutoff to the Wbin? What do you mean by flh?

***EDIT***

These are the 18" W bins I've now got, does anyone know what they are? Just copies of the JBL bin?
