Hybrid Horn almost full range

[abcdmku]

I've been working on a 12" Horn to fill the mid/top frequencies. I hate having the back of the cone go to waste so I ported the enclosure and got bass down to 50Hz!

Here are a couple quick renders of my "MT-112" (the HF horn isn't rendered, it would be in the middle)





For the front to make this full range I'm thinking of putting a compression driver. I'd crossover around 2000Hz. Would the driver being there disrupt the sound of the 12"?

This is the approximate size of the horn, I might go slightly smaller:




Because everyone likes to see the frequency responses:
(only the 12")

Here's a couple pictures:




Oops, forgot to cut the ports to length! They are the longer ones of the stack ^

I'm uploading the spec sheet because I couldn't find it on the internet:

I changed the links. Can you see them now?

A diffraction/reflection box!
Just what we need!

I like to watch at other kind of curves

[grec13]

yes, thank you.

"A diffraction/reflection box"? not sure I understand the reflection part.

and as for the curves, for us Italians, that goes with out saying :P (ironically I just posted in an argentine pride post too, being that I'm both Italian and argentine)

Hi,
well, every boundary is reflective!
IMO if you want a better midrange
go with a real one, i.e. a 5 or 6"
I'm using one! ( see Systems& pictures, the last ones )

I was originally going to use two 8" speakers. The 12" response has a curve flat up to ~2000 Hz and the compression drive I have is flat down to ~1000 Hz. The only advantage a "real midrange" has, is slightly cleaner highs, but it has less bass. The good thing about using the 12" is that it makes these cabinets "full range". I could take these somewhere and use them alone if I had to. (obviously it would be better to use the subs with it too, for my definition of full range is 20Hz-20kHz)

Do you have the plans available for us or is it still a secret? Nice cab to go down 50Hz solid, what driver are you using and is it available here in the US? Thanks!

I'm in the process of building the cab now, I'm going to be on campus from Monday-Wednesday hopefully I can get it done by next weekend. I still need to order the speakers though.
Believe it or not, that response curve is using an MCM 12" :O
