Hello everyone
I'm part of an small group of people in Zürich that loves electronic dance music mainly live electronic techno/ ambient. We have a strong DIY ethos and organize niche events.
So far we could use a PA system by RCF 4xTT2-A (1", 10") & 2x8006 (dual 18") which we liked and also played well with the room. We would like to take the events to new locations now and have the plan to build our own PA system. It is important to us to build the system since this is part of our creative outlet.
The system will be mostly used inside in a variate of different sized places. A room that we are going to use often is about 160m^2 and 3.5m height as a reference. We envision the system as a part of our events and do not want to hide it. As a result we would like to build the speakers visually impressive, preferably horn loaded (easier to style I think;) ). But in the end sound quality dictated the decision and not the appearance!
From my research so far I came up with the following configuration:
1 Mid/ Top Limmer Horn 308
2 Kick Cubo Kick 15 or 12/ MKH-230
2-4 Sub Dual 18" BR or 18" hybrid ala JM-sub118h or even Cubo Sub
I've heard the Limmer 308 and I really like it so this is the starting point. Since the 308 is not playing much below 200Hz (please correct me if I'm wrong) I thought of dividing the sub section into two paths.
Now comes the part where I'm unsure.
- Is the cubo kick 15 suitable to cross at around 200Hz to play nice with a 308? or should I rather go for the cubo kick 12? Is the MKH-230 a suitable alternative?
- What sub is playing well with whatever kick bass bin recommended? Is a horn/ hybrid horn to much for indoor applications?
I have experience building speakers, I build my own HiFi speakers (Granduetta) and I have some experience with acoustics. I used to work for a Swiss hearing aid manufacturer.
Material that is available:
- Everything for building speakers

- A Gisen FP4.13 Lab clone (I know, I know)
- DBX RackDrive PA2 (6 exits so enough if subs are used in mono)
I'm looking forward to your input and am exited to start with this new project.
