In reply to your e-mail....
The key specs for your Bumper drivers are Fs=44.9Hz, Qts=0.26, Vas=4.7 cu.ft., Xmax=0.17", Impedance= 8 ohms, SPL =98dB/1W/1M.
Now, I'm not all that knowledgeable about horns, but the low Qts of those drivers suggests to me that a rear-loaded "scoop" type of horn enclosure might be a good choice.
A horn designed for good woofer duty is NOT going to be compact. For example, the Eminence single rear horn loaded (scoop) bass enclosure from their "High Power Loudspeaker Enclosure Design and Construction" book occupies 14.1 cu.ft.. Bear in mind that, for the best performance, the horn alignment (throat size, mouth size, length, and chamber volume) needs to be matched to the driver. And that's where my knowledge of horns runs out.. :-).
The LabHorn is designed around specific 12" drivers from Eminence - it probably isn't going to be much use to you if you plan to use your current drivers.
Another possibility that could work for you might be a series-tuned 6th order bandpass enclosure, but again that's a pretty complex align to design, build and tune.
If you want to stick with horns, Google HornResp - that's a program that can be used to design them. There's also a wiki available that provides instructions on how to use it. I've provided a link to the homepage above.
