You posted 3 measurements. In that post, there is no context. There is no way to know if these measurements were done in the same session, if the mic was in the exact spot for all 3, if the mic was 1" or 4M from the subs, how you calibrated SPL in REW and many other important specifics to the point you were trying to make in one sentence. If you want your posted data to be credible, include the necessary information. I mean that sincerely, FWIW. If you don't have the time, as you say, don't do drive by posting and expect to get respect from that.
On just this page, you said:
The context is not very deep. The suggestion is that the max burst curve, the numbers that form the curve being the controversy from the OP, is irrelevant when you put a sub in a room. When the point having been made is that the sub changes its FR under varying levels of input and content, the context of your comments is clear. Any other meaning that might have been intended either lacks proper explanation or is not relevant to the point.
I've used 16 Fi drivers. I'm very familiar with the inductance hump and the general driver design philosophy of Scott, et al. I designed and built a notch filter and L/Ts to alter the response (remove the hump). To be sure that they couldn't revert to their naked response during playback (that the hump would not reappear when the system was at reference level with demanding source), I used 8 of them and 18KW.
If I used one of them and 500W, I know what the result would have been. Please don't drag me through this point over and over. I know what the result would have been. No stretching here. I saw it immediately when I was thumbing through DB one day.
There are lots of reasons why someone might like a non-linera frequency response. Tilted, house curve, hot SW trim, top heavy, mid bass slam, etc. I attended a blind listening session where the only thing the listeners knew where what subs would be used, but not at which session. The host bumped one narrow frequency band of a sub by +5dB and passed it off as a whole different sub, which no one questioned, but everyone heard and noted. I actually guessed one was ported and the other was sealed, but both were the same sub with just that little change in FR. Some loved it, some hated it, some liked it and some didn't care either way. What does that prove? Zero.
And reviews? I've never read one where the reviewer didn't like the sub, going back 12 years now. Talk about irrelevant.
I'm not in this thread to express personal listening preferences. I'm just not OK with the way more than a few members have treated ShadyJ because of embarrassingly silly reasons. And, none of them has added a single word of usable information to the subject or subwoofers in general. It's like a high school clique raggin' on a student because his shoes don't match his belt.
