This thin design has a very minimal effect on the response. There is a little variance between the two in the lower range, but it’s not too bad.

And here are the two speakers. Please note per Proposition 65 that this product may contain chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.

Compare that with the csd of the LGK’s that I posted in this thread: For some reason a lot of people have been lead to believe that these stiffer cones will have lower distortion. I learn a lot every time you post something like this. Based on the off axis measurements, I should have the speakers turned to face me, correct? Not something I have really understood in the past. Great job on the grill. It will add a little residual ring to everything.

Danny, Thank you for taking the time to measure my speakers and for the very detailed fr888ex of the results. But if you really consider what is going on then you can understand that with the output of the 1kHz range and down being equal, then the break up from foujtek and up has been reduced by 5db.

These high-performing cone drivers feature thin-foil aluminum diaphragms that shed resonance rapidly, for exceptional detail and smooth frequency response. The impedance looks good and is free of any box resonances. A couple of questions: Danny Richie Facilitator Posts: What is the angle for the different measurements on the off axis measurement? I will take some time and study them. IOW, the shorter the traces on the Z axis that appear to come off the page are, the better.

As that lower distortion will equate to cleaner sound.

See details for additional description. This will help the sound a lot. See the before and after curves.

Show More Show Less. I got them from Madisound. Skip to main content. So I added a small inductor and Mills resistor to this as a baffle step loss compensation filter. This is easy to hear. 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.

There is an expected baffle step loss below 1kHz. I look forward to ordering them. This item doesn’t belong on this page.

The top of this peak is where the computer sets the 0 on the scale. You mention a small inductor and founetk but it would be great to know the values as the result looks like they worked well.
