Dear God what is this monster?? Some kind of belated April Fools joke?

 

Flat response FLH! I've been toying with this alignment for a while, just messing with sims to see what pretty results come out. I used high compression ratios and stupid strong motors. I can't wait to see what drives this thing! The distortion profile is unbelievable. Virtually no output compression besides a blip at 15Hz?

 

And holy hell that performance?? Just smashes everything else yet tested. It's also the largest, but it looks very well optimized! Even output per liter looks exceptional. This horn is long enough to provide loading down to 15Hz but wide enough to handle 4 18"s?

 

Simply unreal.

I'll post the detailed notes pics and everything when I get a chance. Really wanted this posted up so rushed to get the data loaded at least.

Heheh. Feels good when a new system arrives and totally obliterates the top graph on the CEA burst board. :P

 

But also...

Well for this case he just needs a K20 per driver, that would work.

Haha. Nah. Part of the goal was to not ever worry about thermal limits or driver excursion limits. Never even used a high pass. Looks like one isn't needed if the k20 can't get there. I have a lot more to post on it but I'm heading out of town to see family this weekend so it'll be a few days. Recommended amplification is come at me bro.

Also Scott, the max long term sweep is kinda funny. We're giving her all she's got captain! Amp is like I'm done.

Awesome B)

 

That with some room gain should pretty much do it :lol:  lol

 

 

I thought that it seemed pretty compact for that output, those drivers and being a horn.  20-large, though?  Not cheap! :o

 

How the hell did you move it, Josh?  lol

Max burst looks great (I do not like looking at that figure first as it is misleading IMO) but so do the other measurements. Yeah it's big. Yeah it's not cheap. But WOW on the performance level in sheer output. Nicely done!  :D

Actual cost for me including an amp is about a third of what I listed. That was more of a MSRP if it was an actual product to be sold. Still eye gougingly expensive and utterly impractical no doubt. The fun factor is rather high though.

Just another example of SPL drag racing dominating this forum ;)  :P  :D

I don't even understand how any of that is even possible. The enclosure, the size, how you fit 4 18's in there. I just don't get it.

It's my usual MO. Cram way too much into too little space. Spend a very long time trying to puzzle it together. In this case this is the absolute max dimensions that will fit.

I've been trying to simulate anything that could perform at this level and they're all coming out 3dB too low on the sensitivity for the same size cabinet. Maybe I'm doing something wrong, but I have no idea how you did it. I gotta hand it to you, this is one monster of a horn.

 

As for impractical? Not much more than Danley's TH812, BC218 and others.

So what's happening with the rockfords now? Or is this going to some other home?
