What do you mean?
All the settings we used at that meet were listed in the first few posts, including the exact iNuke DSP settings - with screenprints. I don't know what you refer to?
To your point, during Friday night's setup period we saved the documented DSP settings on the iNuke DSP 3000 amp. We then recalled the saved settings on Saturday for the meet and Sunday for the retest. There is no secret to what we did. It's all publically published, and the settings were blessed by the sub owner. The owner of the 18.1 pair was very
enthusiastic about the way the subs sounded in my room on Friday night. He stated they sounded the best he had ever heard them sound coupled to the iNuke DSP 3000, as witnessed by several other avsforum members who were present - HuskerOmaha, kwarney, and deserdome. PM them if you don't want to take my exclusive word for it. Take that for what you will.
Take Note:The iNuke was not out of gas on the musical clips at all at the volumes auditioned as verified during the Sunday afternoon's retest time. The clip lights never engaged for any of the musical demo pieces during the retest at the standardized volumes, and we played and replayed the deepest notes, and the loudest sections. There were no clip lights on the slow sine wave, and no clip lights on the Bass I love you track. The biggest controversy with the CHT sub's performance from the people who felt the CHT were treated unfairly was that people said they were underpowered for dynamic sections on the iNuke DSP 3000 amp. Two conflicts to that. 1) the owner chose to use the iNuke DSP 3000, despite my verbal caution on Friday night that the bad sounds we heard during Friday night's setup demos for the movie section and sine wave bottom note would be unacceptable in the next day's meet when compared to the more expensive subs. To that verbal caution I issued the owner, as witnessed by the aforementioned AVSforum attendees - the 18.1 owner said that his subs sounded the best he'd ever heard the subs sound, and if he wanted to proceed as it was, saying how good they sounded would over-ride the possibility or expectation of a few bad noises. He also mentioned he was afraid his Dayton amp would power off, when I questioned if we should consider using that amp. Also noteworthy, on Sunday's retest to see where the amp was clipping - - - the music section never clipped the amp - so whatever recognition the 18.1 pair received for their performance in the music section was merited on their own ability, and not due to the amp. (since no clipping was observed).
For the movies one could argue the iNuke amp hurt their perofrmance, but given the owner's blessing, and fears of the Dayton amp turning off, it could also be argued the iNuke didn't hurt their scores. I personally STRONGLY believe the CHT would have performed worse in the blind results if powered by the Dayton. This was certainly made my belief after witnessing the two amps back to back on Sunday's retest timeframe and hearing how much weaker the Dayton amp preformed the standardized demo tracks - both music and movies. There was no umpf using the Dayton amp in my room. none. The CHT owner at the time agreed fully with me, and thought the 18.1 subs again sounded great on Sunday, verbally questioning why the subs sounded poor during the blind demo on Saturday, since the subs sounded great (in his opinion) on Friday night and sounded great (in his opinion) on Sunday with the iNuke, since the same DSP settings were used on all three occassions? Answer --- Because on Friday Night and Sunday the 18.1 wasn't compared to subs that cost several times and much are were MUCH more capable. This wasn't a behind the curtain type setup. There were three of us involved in setup, and several others who observed the process. The CHT 18.1 owner was one of the setup guys, the HSU owner was on of the setup guys, and I was one of the setup guys. We all watched and verified each setup step, which is why we didn't make any known mistakes over the course of the setup. We had three pairs of eyes verifying everything and a written checklist to follow on each occassion. Vendors, Mark Seaton and Jeff Permanian were also present for the setup, but just observed. They did not offer advice, even when we initially asked for their opinion on a couple matters relating to sub positioning and crossover levels. They took the wise position of not being involved in anything at all - lest someone cry foul.
Any of the test results can be repeated by anyone with CHT subs and a DSP 3000 amp interested in doing so since we documented all settings to the nth degree, and were able to repeat the issue on three occassions - Friday night, Saturday during the blind meet, and Sunday in the retest timeframe. I offered the retest results verified through on Sunday thorugh PM to Craig Chase before they were published so he could try to recreate the problem with his own iNuke DSP 3000 amp he owned at the time on a pair of 18.1 subs. Seems like something he'd be interested in if he truly felt his subs were misjudged!?!?! I offered to e-mail them to him, snail mail them to him, or whatever, but somehow get him the results. Ominimic captures, screenprints, video, etc. He wasn't interested. My theory is the only reason he wouldn't be interested, is because he already knew this was to be expected or could recreate the issue from what we'd already published without the additional retest data, which showed the same thing as the meet results. There is a heck of a lot more I'd like to say here about the frustrations I encountered afterward in dealing with CHT through PM, my deleted posts on his public forum, with him publically saying I wasn't responding (we have screen captures of some of those in my 2012 thread) etc. and just generally having my integrity and honest intentions attacked. But I'll just let this post stand at the above without the other gory details. The information above addresses your specific comment. The above details are honest specifics as they relate to the meet setup. Those who know me wouldn't question my integrity otherwise. If you'd like to further question the results of our 2012 thread, please do so in that thread, as that would be a really off topic here. I'll be happy to respond there, though I think we've pretty much addressed everything commonly questions in spades throughout the course of that thread.
