Contrasseur Posted July 14, 2016 Report Share Posted July 14, 2016 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. Link to comment Share on other sites More sharing options...
Ricci Posted July 14, 2016 Report Share Posted July 14, 2016 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. Link to comment Share on other sites More sharing options...
Infrasonic Posted July 14, 2016 Report Share Posted July 14, 2016 Heheh. Feels good when a new system arrives and totally obliterates the top graph on the CEA burst board. But also... Link to comment Share on other sites More sharing options...
Infrasonic Posted July 14, 2016 Report Share Posted July 14, 2016 It's official. You need a bigger amp, Josh. Link to comment Share on other sites More sharing options...
Funk Audio Posted July 14, 2016 Report Share Posted July 14, 2016 It's official. You need a bigger amp, Josh. Well for this case he just needs a K20 per driver, that would work. Link to comment Share on other sites More sharing options...
Leons. Posted July 14, 2016 Report Share Posted July 14, 2016 ULTRA COOL Josh!! I really wonder what is going on under the bonnet.. Link to comment Share on other sites More sharing options...
Ricci Posted July 14, 2016 Report Share Posted July 14, 2016 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. Link to comment Share on other sites More sharing options...
lilmike Posted July 14, 2016 Report Share Posted July 14, 2016 Wow. Just wow. Nice work, man. The results look outstanding. Link to comment Share on other sites More sharing options...
Ricci Posted July 14, 2016 Report Share Posted July 14, 2016 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. Link to comment Share on other sites More sharing options...

MemX Posted July 14, 2016 Report Share Posted July 14, 2016 Awesome That with some room gain should pretty much do it lol I thought that it seemed pretty compact for that output, those drivers and being a horn. 20-large, though? Not cheap! How the hell did you move it, Josh? lol Link to comment Share on other sites More sharing options...

Electrodynamic Posted July 15, 2016 Report Share Posted July 15, 2016 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! Link to comment Share on other sites More sharing options...
Ricci Posted July 15, 2016 Report Share Posted July 15, 2016 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. Link to comment Share on other sites More sharing options...

BeastAudio Posted July 15, 2016 Report Share Posted July 15, 2016 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. Link to comment Share on other sites More sharing options...
Ricci Posted July 15, 2016 Report Share Posted July 15, 2016 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. Link to comment Share on other sites More sharing options...
Contrasseur Posted July 15, 2016 Author Report Share Posted July 15, 2016 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.

Ricci Posted July 15, 2016 Report Share Posted July 15, 2016 The 2 cabs that were made are going into my PA / stereo at the warehouse, into the spot that the GH's used to occupy. Still got the DO sealed system at the house. No plans for any changes to the LFE channel there for a LONG time. I couldn't fit anything like this in my HT room.

SME Posted July 17, 2016 Report Share Posted July 17, 2016 Err, been meaning to say something here. This is fantastic! Congrats again. Did you mention what drivers you used, or is that a proprietary secret? In any case, those would seem to be capable of providing ULF support for large outdoor shows and movie presentations. I wonder what chance in hell there would be of convincing whoever purchase equipment for the Red Rocks Amphitheater venue in my area that they need a commission like eight of those. I'm sure their movie nights would be a real hit! Of course, I'd love to hear an array-able like the Synergy horn system there as well. It is often windy there.
