James, I'm not sure what you're trying to say by posting these graphs?
Are you actually saying that you don't get what nfraso's posts are about?
Suppose that back when you asked me if you'd see an improvement if you went from 4XEds ported to 8xEds sealed, the same thing happened then that nfraso has experienced with the CHT sealed subs.
My answer to you was to post a simulated naked response, and extrapolated in-room response and an enthusiastic YES, you'd see a huge improvement with the new system. (That's actually, in essence, what my answer was)
Now, suppose you did the build and the results were off by more than an octave and worse than the 4xEds ported. Would your response have been to apologize for the difference and tell everyone it sounds great and that you could just EQ it because you have headroom?
Go a step further and imagine that, when you questioned the results vs what I promised (and I did absolutely promise with no reservations or disclaimers) that I replied that you just don't know what you're doing, that you're a liar, that your graphs are faked to make me look bad because you have an agenda. Then imagine that I had asked several posters I know to report any posts you make in reply to my accusations as inappropriate to attempt to get you banned from AVS. Then imagine I filled your PM inbox with insults, calling you "junior", "incompetent", etc.?
So, that would all be cool with you? And, if you ever mentioned it again down the road, it would be cool for me to just tell you to get over it because that was in the past and you're just axe-grinding dead horses?
Here's the scoop on your measurements: The red traces are the Ed system, computer sim and in-room measurements. The dark blue traces are nfraso's close mic measurements (which are accurate) and your in-room measurement.
They make perfect sense. The Eds have a flatter naked response and it's reflected in the in-room comparo. But, I don't get you saying they're the same. A 10dB difference <10 Hz is not anywhere near the same, and you know that. Yes, you can use PEQ to lop off the top end of the CHT stuff, but that's exactly what nfraso said he had to do and was eventually banned for saying. And, where is this "mid bass slam" (whatever that means) if you use EQ to lop it off? And, what difference is the presentation when you DON'T use EQ to flatten it out? Are you saying you don't hear/feel an 8dB average difference <20 Hz?
I also don't get what the comparison of the CHT system in your room to any other system in your room has to do with what nfraso is saying, which is simply that he bought the subs based on the word of Chase who assured him and everyone who can read that the sub's naked response would be (+/-)3dB, 23 Hz and the F3 was actually in the 50s Hz, more than an octave higher.
Sorry, but if a sub manny promises a 20 Hz tune and when a customer gets it it's a 50 Hz tune, get real. Head room is irrelevant. In-room is irrelevant. Whether or not you or anyone else like them as they are is irrelevant. And, when he questions the huge difference and is banned, ridiculed, has his profile altered and sees the manny principle publicly telling people to ignore his insanity and agenda, you (or anyone else) don't get to come into the thread and school him as to what course of action is the correct one.
