Hello Socaflex.

What EAW cabinet are you trying to replicate?

[Socaflex]

sb 850 or sb 1000 and the top for the sb 850 sub.

[OMNIFEX]

The SB 850 is nothing more than a bass reflex dual 18
bin.

This will be the easist to build. However, you will need to tune the box according to the drivers you are planning
to use.

The SB 1000 is a reflex bin with drivers angled in a "V" fashion

This will be a little tricker to design, due to having the proper spacing between both drivers to prevent the cones from smashing against each other when driven

The KF 850 is a fully Horn loaded top box, and, honestly
would be cheaper to buy used, than getting the right
driver components to replicate the same sound.

How skilled are you in building horn boxes? Do you
know how to measure the flares according to the
length of the frequency? Can you purchase the horn
flare for the compression driver? Do you know part
number? Which KF 850 were you intrested in building?
They made like around 4 different versions of this
20+ year old cabinet. Driver components have changed
through the years also.

If you are up to the task in building some, go for it!


If not, go get some used ones.

IMHO the only box I would build would be the SB 850.
The SB 1000 is a clumsy design, and, frankly doesn't throw
nowhere as close as a folded horn. Heard plenty of times
I was never impressed.......

Thanks for the advice i use eminence omega 18 inch subwoofers would that be good to put in the sb 850 sub box and as for skill i am a newbie but i would have taken the design to a carpenter or someone who is good in wood working. Are the designs available.

[OMNIFEX]

The Eminence Omega 18 is ok. But, the Magnum 18 LO
would be a better choice if you want to stick with the
Eminence line.

I can scale the SB 850 for you. However, I rather be
certain if you are going to use the Omega's or something
else.

[Socaflex]

i allready purchased 4 omegas you do not think that would be good.

[OMNIFEX]

There good. Its just they won't perform like EAW SB 850's.
EAW used RCF in their earlier model, then moved over to B&C.

You purchased them already so, we'll make the best of it.

Now. Since this is a PA Box, we cannot rely on room
gain, nor heavy eqing to make this box sound good.

It needs to offer the frequencies without any aid.

The Box will be tuned at 40 Hertz, giving you a - 3dB
at 37.82 Hertz Normalize Gain. If you like what you
see, I'll give you the cabinets dimensions.

This is the comparison when using one box versus two.

Purple Represents Two Cabinets

Blue Represents One Cabinet

You're looking at 104 dB from 100 - 40Hz using one box, and,
110 dB from 100 - 40Hz using two boxes (2.83 volt, 1 meter)

Note: Measurements are an estimate (+/- 1 dB)
