A request for the guys who know hornresp

[Rightbrained]

I have 2 of the PE buyout Eminence 12" DVC subs I would love to build horns for or a single horn with dual drivers.
Anyone care to run the numbers through hornresp? I just havent had time to learn it.
Specs are:
Fs 23
le 1.73 mh
re 2.78 ohms
spl 88 db 1w/1m
vas 5.66 cu. ft
qms 9.43
qes .44
qts .42
xmax 7.0 mm
sd 519.5 cm^2
mmd 73.5 g
bl 8.47

Thanks!

How large a box? And how low do you want to go.

Enclosure size is no concern so I would really like to see how low we can get these to go regardless of size.

Ok buddy. You asked for it.

Here is the way it works. A perfect 20 hz horn is 10 feet by 10 feet. If that's what you are looking for by size does not matter than no problem. Punch in your numbers into Hornresp and use the horn tool to generate a perfect horn as dictated by the low end you want. Be prepared for something with a volume around 150 cubic feet.

So I'm thinking size does matter. Openings to your room where you will put this will dictate the maximum size to be sure. So if you have no idea then neither do I. A well designed horn is quite a bit of work. Here is a starter for you to play with. By the way the horn volume is 144 cubic feet. If you can actually corner load this horn in a basement with three concrete surfaces meeting your flat to 20 hz. The SPL is from one watt input referenced to 8 ohms. The drivers have been simulated as a series set and the acoustical loading is very realistic to what you could get in your house.

Send me pictures if you build it!

Thanks for running the numbers. The screenshots you provided are a big help and I appreciate it.
I have a FL horn in my theater room already but I want to learn what goes into horn subs as far as design goes.
