Has there been any development on the 4x8 inch cab? I can't seem to find any additional postings showing plans or builds.

Handful of pics/vids from over the weekend with the two completed Type C cabs.

The sound is fantastic. I went hog wild with the measurement mic on top of a hill in Morro Bay last weekend. Frequency response is exactly what was advertised and it was really easy to EQ and integrate with the rest of the system. There was a big cancellation happening between the paraflex and the kick and once I added the right delay settings every kick drum felt like being jabbed in the sternum with a boxing glove when standing close to a stack. Excursion was under control all night even with huge bass drops that went very low. They are also surprisingly directional so when we pointed them towards a hill we were on instead of the valley below us it made a substantial difference.

Grants for the work zigguratSound.

Looking to the picture looks like you system is 4-way, is it right?

In general digital processors works with 3 way system, so maybe your tops are using a passive crossover and you feed them with 1 way (top).

Bass = 1 way
kick = 1 Way
Top = 1 Way (split 2-ways passively)

In addition, could you share you experience and thoughts why you choose these configuration?

If you eliminate you kick and just use your sub-woofer and tops, what would you system lacks? aren't your tops capable to go low to 100Hz ?

Good question. The system is 4-way active. We use a DBX driverack to split everything three-way and the 20hz-250hz band gets split again between the kicks and the subs by running that signal into a Behringer crossover. I can only imagine the biggest signal degradation happens there as a result, but the bass sounds OK to me.

If anyone can recommend a logical next step to migrating away from the Behringer, I'd love to hear it.

The tops can reach around 100 hz but the ports are in the back. I built them this way with the expectation that we could just run them at patio BBQs without needing any kicks, just a pair of 15" bass reflex subs.

I opt for the kicks outdoors because they make the rig taller, give us more dispersion control for those frequencies, and take a big load off of the mids. With a taller rig, we still have the kick frequencies at chest height, and everyone can still hear the mids and highs with good clarity even if a tall-ish man walks in front of a stack.

There's also my own dumb-guy reasoning that everything looks cooler this way and we have more surfaces to light up. I'm not ashamed to admit it.

Hi zig.
I guess you don't want to run mono eh?
I have a dcx 2496 and run it mono for 4 way.

Nice, it's good to know that's an option. I'm fine with mono tbh and love to run speakers in a big stack. The crew played some tracks over the weekend though that sounded really trippy when we got to experience the way the producers panned certain sounds and it was a lot of fun.

I don't think the DBX unit I have provides the ability to output 4-way mono but I've been thinking about picking up a used behringer DSP just because. Does it have a decent iOS app? that's a nice perk of the DBX. My wife was playing lots of house music with very bright-sounding disco vocal samples and I was able to walk around the dance floor with a tablet listening to the mids and figuring out how best to attenuate them for her set.

e: here's another pic of the stacks in my living room since I'm here

Hi Zig.
If you have the pa 260 you could run 2 channels for stereo tweets, 2 channels for
Stereo mids and use 1 channel for mono kicks and 1 channel for mono subs.
Just a thought.
