Did you run Dirac on your Tektons above 100hz or so and adjust the curve? I found that if I reverted to no filtering above 100hz (shrunk my curtain to sub 100hz) the Tektons are free to do their thing and they sound great. I think however Eric does his magic it is best left to him. That is my personal view based on my room and speakers, your results may be different based on your preferences. Hi Mark, No I hadn't. I know the Tektons are great but the real world living area isn't an anechoic chamber where the Tektons shine the best. I'm sure the in room frequency response in my measurements look nothing like Tekton Ulfberhts in an anechoic chamber. Wish I had that graph too though! The room is actually what I've been dealing with for months now. First by sound absorption panels, refraction, and now by DSP. I realize I have a lot to learn with room correction. Tis my first few days so I'm still teething. Much appreciate your advice and suggestions Mark. Enjoy,William The fun thing about this sport is you never stop tweaking. Just make sure you save the settings when they sound good in case you ever have to get back there. I may have made that mistake once or twice

Enjoy,William Shimei, Is the curve you like the 6db Harman Curve that you adjusted to extend the high end? What about the bass end, did you use a 10Hz cut off or extend the bass boost as far as possible? To me the 6db Harman curve is excellent for most things. I like the 8db curve for movies and the 4db curve for music since we can flip back and forth. Also did you pull the curve down or leave it as it was loaded?

To my ears the Harman Research 6db curve sounds best, better than the NAD curve. The NAD curve in the above screen shot over exaggerates the bass wayyyy too much and over drives the center channel to the point where the curve needs be flattened or the XO point passed higher up. So far the Harman 6db curve suits me best. Did you run Dirac on your Tektons above 100hz or so and adjust the curve?

Low bass measurement in ANY room other than perhaps an auditorium is problematic. Don't forget the longest wavelengths run 50 feet or MORE. By 'ear' at the lowest frequencies is certainly on the table. Others have mentioned Anachoic response? Anybody here ever been IN such a space? I've been in a remarkably well done recording studio. You could stand back-to-back with someone and not be able to localize where the voice was coming from. Ear popping weird. And that wasn't even a true Anachoic space. Just well damped. BTW? The walls were a foot or more thick with opposite walls in a sawtooth pattern of different angles. Even the ceiling was sawtoothed so there were Few if ANY parallel surfaces. If you had such a space, I doubt you'd like it for ANY listening purpose.

I believe the curve I extended the high range for was the NAD. I'm now using the Harman Research curves. Here's the 4db Harman curve applied to both my Left and Right mains running full range: Here's the Center which is also a 4db Harman curve that I flattened out. My XO for the center is a 70hz high pass. And this is a sub using a 6db Harman curve. My subs are xo at 90hz low pass: Here's the sum of my 3.2 system: In the above summation the low end topmost line are the 8 10" subwoofers looks green or turquoise. The next lines are the purples which are the mains but the subs in the mains consists of 4 12" woofers. Of course the Yellow is the center channel. I was thinking about running the subs flat. Looking for suggestions.

However, I flattened C curve and I also left the 4db gain for the subs but flattened it up to 90hz. Interesting that the main's L and R 4 12" subs extend lower than the 8 -10" in two sealed 4-10s. Subs: Sum: Now for a day of listening! Thanks much, enjoy.
