Smooth at 1/6 octave, that's as good a resolution as you can hear. The notch at 80Hz is probably sourced by the reflected wave off the wall behind the listening position, but it's narrow enough that you may not be able to hear it.

My experience so far...
It sounds great , a whole new dimension.... So much power and dynamic.
Control and detail, my old subs sounds weak comparing to this.
Tomorrow i will try some parametric eq.

It has been, on occasion! (Lie down on a t-60 sometime with your head at the business end. Make sure to attenuate as needed!

Re: 36" THT Low Profile, Warning lots of coffin pictures
ok, some more measurement sweeps at listening position.
10-150hz, scale 50-100dB (2dB between each line) no smoothing.
And with basstraps...
It evens the dip at 50hz and takes down 55hz peak.

That last chart looks great. I need to build one of these sometime soon.

Some follow up measurements with EQ.
Re: 36" THT Low Profile, Warning lots of coffin pictures
That dip at ~82 hz, is it due to mic location?

Probably, it indicates a 3.4 foot distance from either the mic or the speaker to a boundary.Tom Smit wrote:That dip at ~82 hz, is it due to mic location?
Re: 36" THT Low Profile, Warning lots of coffin pictures
Mic (UMIK-1) was at listening position about 40cm from backwall and THT in front corner standing up shooting into celing about 65,5cm from ceiling.Bill Fitzmaurice wrote:Probably, it indicates a 3.4 foot distance from either the mic or the speaker to a boundary.Tom Smit wrote:That dip at ~82 hz, is it due to mic location?

Re: 36" THT Low Profile, Warning lots of coffin pictures
That's probably the source of the dip. Move the mic further or closer to the wall to be sure. LP placement is like sub placement, you should be either very close to or very far from walls.El dillo wrote: Mic (UMIK-1) was at listening position about 40cm from backwall .
Re: 36" THT Low Profile, Warning lots of coffin pictures
Thinking out loud:
40 cm equals 15 3/4 inches, a hair over 1 foot.
65.5 cm equals 25 3/4 inches, a hair over 2 feet.
1/4 of an 82 hz sound wave is 3.4 feet, or 41 1/4 inches.
How far is the mic from the THT?
