I have four 15" 600 watt drivers I want to use in a pair of bass bins for a P.A.
Are there any designs and plans I could use, preferably forward firing cabs?
I know three of the drivers are Eminence but I cant remember the fourth.(theyre stashed in a friends lock up)
Any suggestions welcome thanks.

First you need to know the T/S parameters of the drivers before you can design anything.
Unless you are putting one amp PER driver, it is not a good idea to run two different drivers off one amp, it's a good way to blow one or both up.
The next question is what mean "bass" to you, and what is the application, what is the maximum size per cabinet that you can live with.
What gear will you run them with?
What do you want to PLAY through them?
Stuff like that.

Bass bins
Well, we are a five piece rock band consisting of two guitars, drums, bass, and singer.
We don't have any P.A. equipment yet, and building a pair of 2x15" bass bins is a start.
We assume our mixer outputs will go into a crossover then out into two separate amps, one to power the bins and one to power the mid/tops.
So I assume the bins will be mostly handling bass guitar, kick and toms.
Obviously we would like the bass cabs to be as portable as they could be, but some dimensions...maybe each bin could be 19" wide, 36" high and 18" deep. One amp to power both bins I assume.

The size you mention is only 7.125 cubic feet, which is rather small for a pair of most Eminence 15", low frequency output will be weak.
From a practical standpoint, 36" high is still too low for top cabinets to be stacked on- you want the bottom of the top cabinet at head height for even coverage.
Better to make the cabinet more like 30" x 30" x 16.5" (slightly more cubic feet than your dimensions) and use a pole mount top hat so a simple pole can support your tops using the sub as a base.
A slot mount allows the frontal dimension to be shorter than the two speaker's dimension, look up PPSL for examples.
Hi,
You can try this 18 sound plan ..... (15" dual sub-woofer) . I had tried this earlier. Powerful lows & very low distortion. Works with a wide variety of drivers.

Doesn't Eminence have cabinet design suggestions on their site by the drivers specs?
You could check out Bill Fitzmaurice, he has lots of plans for bass bins that use Eminence 3015 LF drivers and such. They are all designed using the drivers T/S parameters. His plans are typically horn loaded as well.

I had used Eminence Magnum 15LF & DefinImax 4015LF both on these
18 Sound plans (dual 15" subwoofer boxes).
Interesting, but I don't see why you would reverse mount the driver on a bass reflex design. I would just move the baffle to nearly the front, inline with the end of the ports, and mount both woofers normally. This would give a larger interior volume and lower tuning.
This arrangement ensures cancellation of driver non-linearity thereby reduces distortion. Some great examples of such boxes are EAW FR250,
Peavey DTH218 ..........
The EAW FR250 uses Eminence OEM 15" drivers.

Something similar to these would be ideal, of course they would be a lot bigger I assume...

I understand why it's done, but I don't really believe it makes much of a difference, when the space could be used for internal volume. I've built open baffle dipole subs with one driver reversed, didn't think it made much of a difference. You also get a bit of motor noise and basket chuffing off the back of the driver.

A dual Eminence Kappa Pro 15LF2 PPSL design, 32" x 24" x 24". Can also be 36" x 30" x 18" (no cut list for this variant).

Sorry I don't understand the photobucket diagram thing you've posted above. Are there any diagrams showing the finished box? With the height, width and depth shown in metres or inches?
