As that lower distortion will equate to cleaner sound. Danny, Vr88ex you for taking the time to measure my speakers and for the very detailed explanation of the results. A couple of questions: Sorry you list me there.

So imaging is improved And check fiuntek the csd. Cookies help us provide you a better browsing experience. This keeps 1kHz range and above from being pushed forward in the sound stage.

What I don’t do is put forth time and effort into my design work then give the information away for free so everyone can buy their parts elsewhere. The top of this peak is where the computer sets the 0 on the scale. Hank Full Member Posts: I am still trying to get my head around the waterfall graphs. Here is the frequency response measured in Jeff’s box.

I do not understand your answer, please provide some more context. No ratings or reviews yet.

It is like looking at the second csd response that I posted that looked really scary and having that graph from 1kHz and down, but having the results of the first one from 1kHz and up. Tuning frequency is just over 65Hz. Be the first to write a review.

You may also fr88exx. I for one appreciate it very much. IOW, the shorter the traces on the Z axis that appear to come off fd88ex page are, the better. I am just about to build a pair to this design. It will add a little residual ring to everything. If there was just one measurement that you can do that will tell you more about how a speaker will sound it’s the cumulative spectral decay.


These high-performing cone drivers feature thin-foil aluminum diaphragms that foubtek resonance rapidly, for exceptional detail and smooth frequency response. So it induces less ringing. Great job on the grill. Compare that with the csd of the LGK’s that I posted in this thread: Then, I will compare them to the LGK’s.

I asked about the component values used in the baffle filter.

I will take some time and study them. I look forward fokntek ordering them. That is typical for any driver used in a small box. And this little driver clearly has some issues in that department. The off axis response looks pretty typical of a small driver too.

Based on the off axis measurements, I should have the speakers turned to face me, correct? Here is the effect of Jeff’s grill.
