Grills will be custom made (but that's gonna take a few weeks).

They are indeed the TH-18 from Xoc1 (with cone correction).

Doing measurements is on the agenda.
First I want to build two front loaded mid-highs (12/1.4).

Btw I hooked them up to a TSA 4-700 (I don't have anything else at the moment).
And they can be felt real easy ,with just 490 Watt on them.

Why not build V2 that drops a bit lower and doesn't have the wasted space inside?

To be honest I actually didn't see the v2 version..

Although the triangle makes the m20 really solid (al is it a bit overkill).



The testcabinet for the mid/highs is planned next week. I am going to try the 12nw76, if it won't do the job I will look further for something else.

Uh, keep reading the x0c1 TH-18 thread , after the cone correction they end up by extending the horn to make the second bend close enough to the cone to become the cone correction, then they move the triangle also and add a bit of extension this way also.

Same has been made for Jbell SS15 (also a later mod I believe)
Then it all comes very close to Danleys subs

I'm looking forward to do some measurements!
I've got a calibrated Behringer ECM8000 as a mic.

For the mid/high section I am probably going for the PM90 (diy mid high).
But not with the BMS.. In germany somebody used the RCF ND950 driver.

The RCF will save me allot of money, almost 600,-

Does anybody have experience with the BMS 2230 horn? someone offered me a pair of BMS 4592 drivers.
They would do the job for the PM90 but there aren't many suitable horns.

The 2230 can be used down to 700 Hz, so it would be on the edge..

I dont have any experience with the 2230.
I do however with the 2236, its larger 60x40 brother.

If you need the extension, there isnt really anything out there that can offer it at an affordable price.
(Big) 2'' CD horns are very rare in make, and probably one of the reasons why the PM90 uses the 1.4'' version instead of the 4592 (which is considerably cheaper).

Sound quality wise i would say the JBL 2380 i have sound a bit better, but they cant do what the 2236 can do down low. Saying that, i traded the 2236 for 2380 a while after i purchased the 2236 along with the BMS 4590 (since i didnt need the extreme extension the 2236 offer (down to 450), i cross the 4590 at ~800) , so if you want 2236 at a good price, i have a pair which is gathering dust.

@Teunos

Thanks for the reply! Both the 2236 and JBl 2380 are to wide for my application.


If the 2230 won't do the job, I will look further for a pair of 4594 (and I know they are hard to find LOL)

Actually i meant 2385, huge mistake on my part.
2230 is 90*50, 2385 and 2236 are both 60*40

Finally did some testing today! 

Music quality was not the best, but good enough for some impressions. I have to say I'm not satisfied yet, it was clearly missing something. 
My guess wood be the bad music quality and not a good summation at the crossover point with the B1520's.

Tops: Behringer B1520 (at the moment I don't have any mid/highs ;D)
Amps: 2X DAP TAS 2400 (one for each TH-18) and a different amp for the B1520 which I don't recall..
processing: Xilica XP3060

Music was just from my phone... so not the best.
Next time I'm hoping to get the mid/highs ready, and to do some measurements with SMAART.

Time alignment possibly? Found this to be an issue with the tham 12.

That was my first though also, but time being limited I couldn't get it right.
Now I am really hoping to have some time for the mid/high's. 
At the moment the "to-do-list" is VEEEEERRRRRYYY long LOL

Getting some training at time and phase alignment is on of them! This goal of the project is to have a nice sounding system, and I am also confident that can be doable. Ofcourse I have to learn lots of things, but that is never a bad thing!
