Hi everybody!

Decided to go for the famous eliminator kick-bass bin, but I just had a lillte question about the two plans, The Electrovoice one:
http://photofile.name/users/tda-audio/182333/3269684/#breadcr
And the second one, witch seems to be the corrected version:
http://zmatek.jinak.cz/diy/pbaudio/w-eliminator/show_construction.asp.html

Can anyone confirm that the second on is the corrected version of the first one, I'm not quiet sure because there are a lot of changes... and it's difficult to read the description.
-    For example, from where do we put the driver in? From the rear board or from the front as in the EV?
-    Should thoses 20mm be kept in the new version:

-     Does the driver have to be fixed as in the EV version, meaning on two wood boards:

I assume number two looks like this:

but refering to the EV plan, the number 1 looks similar... Doesn't it have to be round with a hole having the same diameter as the 15" speaker?

Maybe this post is a little bit full of questions, but it could help other net surfers to fix some of their doubts. Thanks a lot for any help!

All the best,

Leswoodies

Woodie,

I've got two of them cabs sitting fat and lazy in a corner of my storage room (former living room...LOL).
I once opended them but I didn't have a too carefull look at the inside of the cab, thus I just wanted to ID the driver (which I didn't succeded, as it's a blank, unbranded, some kind of OEM speaker, btw).

So I can't actually tell if the baffle is round or square, but if I'll find a few spare minutes, I'll have a go at opening the "klappe" again and check the facts.

IMO there might be better (?) solutions for a kick bin than the good old ELI, that is as it's rather big, so size/output ratio might not be the best.
HD 15 probably be an alternative...
What does the speakerplans-community think?

ps: mine are AAC-made


(not my cabs on that pic!)

all the best

I think you're probably right, there are better kick cabs out there.....I'm a USB convert now. That said I had 4 of the 'Orange' built Eliminators with the EV 200w 15" driver in, they were awsome, very sensitive and sounded great, so I can see the appeal of them.

Excuse me for my newbie questions but I still have a little doubt...
If the two baffle boards have an opening like this

and if the 15" driver is then fixed to number 1, won't there be a problem with the drivers excursion in the red areas:


"Its not two boards in mine its one with a resess cut/fazed out................"
Won't this problem last if as you said, the driver is directly attached to number 2?

I would find it easier to have panel number 1 with an entier hole in the middle and panel 2 with the smaller outcut, but I can't take the risk to rearrenge the plan.

Look i think  that if the two bits of wood you use are the right thickness and you use lots of glue you cannot go wrong!
I also have two made to the plans you show and only one of them is made with 2 bits in stead of one.....

The board that the speaker is mounted to is the one with a  round hole in it , the one with the rectangular hole is fixed furthest away from the cone!!I dont know the measurements but this should give you room on the original ev1s sat behing me at this moment its about 18 mm and then comes the rectangular panel...

So its speaker to panel one [complete hole] then panel 2 rectangular hole[smaller cut out]

ALSO THE 2CM between front and begin triangle is correct!!!!

Depend on what frequency range you're trying for.
 
If you're going for bass, look for high x-max.
If you're going for mid-bass (kick), you need a high EBP (mass corner).
 
In general, the higher the mass corner, the lower the x-max of the driver.
 
Mass corner is EBP*2, or (Fs/Qes)*2.
 
The current version of the driver used in the Eliminator has an x-max of 4mm and a mass corner of 280hz. It is useable to about a half-octave above there, or about 400hz.
 
Bass is displacement (no replacement for displacement).
 
The Lab 12 driver is a good example. A pair have roughly the same cone area as a single 18, but with 13mm of x-max they can play almost 3dB louder than a typical 18 with only 9mm x-max. The mass corner of the Lab 12 is only 112hz, it doesn't work well above 150hz.

I'm reasonably sure if you look at the plans at zmatek, and compare the dimensions to the plans in the Fane book, they will be the same, though the book will have more details. Eliminator seems to have become a generic word for some of the "W" bins. The other plans aren't exact E-V Eliminator plans either, but close. Even E-V changed them from
time to time. The speaker board for one. the late sixties version had a rectangular cut-out on the speaker board, while the ones in the early seventies had round cut-outs on both boards.
