Is the variance in the two speakers just the results of a difference in the driver characteristics or something with my box? The top of this peak is where the computer sets the 0 on the scale. IOW, the shorter the traces on the Z axis that appear to come off the page are, the better. I learn a lot every time you post something like this.

Let me bring the whole scale up 5db and you will see that there is significant break up in the 1kHz to 4kHz range. There is actually a peak in the response above 20kHz that shows up in the csd.

A couple of questions: I do not understand your answer, please provide some more context. Stored energy or cone break up is very easy to hear.

Compare that with the csd of the LGK’s that I posted in this thread: Danny Fr88xe on 14 Feb See the before and after curves. 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.

Be fr888ex first to write a review. You mention a small inductor and resistor but it would be great to know the values as the result looks like they worked well. Danny, Thank you for taking the time to measure my speakers and for the very detailed explanation of the results.

I know you said the shipment was delayed due to the Chinese new year. Cookies help us provide you a better browsing experience. Jeff, Danny is saying that the shorter the decay time, the better. Not something I have really understood in the past. These high-performing cone drivers feature thin-foil aluminum diaphragms that shed resonance rapidly, for exceptional detail and smooth frequency response.

This is easy to hear. 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.

Here is the effect of Jeff’s grill. Great job on the grill. There is an expected baffle step loss below 1kHz.

No ratings or reviews yet. Concerning other full range speakers, are you accepting orders for your new full range driver yet? Based on the off axis measurements, I should have the speakers turned to face me, correct? It is taking a long time to go away. 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 1khz and up has been reduced by 5db.

The off axis response looks pretty typical of a small driver too. This will help the sound a lot.

It will add a little residual ring to everything. Rockford Fosgate T 3-Way 6in. I am still trying to get my head around the waterfall founteek. It is like founteo 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. It will show you stored energy or ringing issues over time. Would you care to share what values you used for the baffle filter?
