These are the internals of the Concept01 speakers. The speaker is 122cm high, 65cm width and 80cm deep.

For the completeness I've also added here the internals of the MartinAudio WSX speaker


I was thinking myself using the MartinAudio WSX for 25hz - 100hz work and the Concept01 as 100hz - 250hz work. But I really want your advice on what to best.

Kind regards,

Generally not a good idea to mix two types of FLH. 

The funny thing is, that the concept1 bins have a larger mouth than the wsx. Your stack of 12 horns adds up to a massive 9,5 m² of horn mouth. 

Your four wsx combine to only 2,5 m². 

So unless the concept01 15" bins are really shite and don't go low, you wouldn't even need the wsx's? 

15k200 looks like a really nice horn driver, the 15LX60 so so, high qts for horn use. 

Have you done any measurements to see what the 15" bins are capable of? Or comparison in general between the two?

Edit: and since you have popped a speaker open already, you could do the diy community a great service: take the measurements of the cab and draw up a plan 

Further benefit of releasing the plan: it could be modeled and evaluated in hornresp for hard, fact-based analysis!

 yes mate. That as well 😎

This is really interesting. It looks kind of like the traditional scoop horn path, but with the driver baffle moved to the back of the rear chamber. Simple, no wasted space. Just the height and depth of the cab result in almost 2m horn lenght just from the mouth to the upper right corner, before the first 180° bend. Must be around 2,5m overall lenght? But the back chamber is of course much smaller than that of the wsx.

The scoops are half jbl 4520 speakers. Loaded with black widow 1505 KA DT. The tops are custom build. The black horn is a peavey horn with a jbl 2425 behind it. Below are 2x jbl e110.

4 times half jbl 4520 bins again. This time loaded with 4 unknown brand drivers. The tops are a custom build, something like the SMT212. A unknown horn with a jbl 2425 and 2x jbl e120.

I've also 8x sa4512 bins with jbl e120. And 4x DAP StageBlaster SB1-B bins.

Was looking at your crews fb page, you mix a lot of different cabs.

I think when I use my own processor they sound lovely, crossed at 120 and the tops properly delayed. When I use the processor from MasterBlaster they sound differently, really high crossed at around 800 i think.
The bass sounds really nice and warm and on really loud volumes the bins don't start to make fart noises (no more air movement than there can be displaced).

I used the WSX bins also on a party and I think they can do more dB's, but at higher volumes you start to here the fart noises. But compared to other modern high volume subs I guess that it is normal that the woofers move more air than they can displace in the horn.

I don't have any measurement gear, not even a microphone.

Yeah that is the place where I started with my quest for information about this bin. But the original creator of these bins doesn't reply there anymore. And few that still respond there are from the 90's era and not of the beginning in the 80's. So they could help me with some stuff but not the exact details.
