It will add a little residual ring to everything. IOW, the shorter the traces on the Z axis that appear to come off the page are, the better.

You may also like. Jeff, Danny is saying that the shorter the decay time, the better. Concerning other full range speakers, are you accepting orders for your new full range driver yet? I got them from Madisound. It’s not bad actually. Then, I will compare them to the Fr88ez. Sorry you list me there.

See details for additional description. This keeps 1kHz range and above from being pushed forward in the sound stage. These high-performing cone drivers feature thin-foil aluminum diaphragms that shed resonance rapidly, for exceptional detail and smooth frequency response.

In short, at the same output level the ringing will be less sever. And this little driver clearly has some issues in that department. 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. I learn a lot every time you post something like this.

I am just about to build a pair to this design. I for one appreciate it very much. So it induces less ringing. The impedance looks good and is free of any fkuntek resonances. Cookies help us provide you a better browsing experience. Based on the off axis measurements, I should have the speakers turned to face me, correct?

Packaging should be the same as what is found in a retail store, unless the item is handmade or was packaged by the manufacturer in non-retail packaging, such as an unprinted box or plastic bag. Danny, Thank you for taking the time to measure my speakers and for the very detailed explanation of the results.

There is a little variance between the two in the lower range, but it’s not too bad. There is actually a peak in the response above 20kHz that shows up in the csd. 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.

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. If so, I will be contacting you to order a pair as well as a couple of filters plus diagrams unless you are giving out that info for free.


I hope that helps a bit. That is typical for any driver used in a small box.

I will take some time and study them. A 5db reduction in output means it didn’t play near as loud and wasn’t as excited. I look forward to ordering them. The off axis response fd88ex pretty typical of a small driver too.

Rockford Fosgate T 3-Way 6in. You mention fonutek small inductor and resistor but it would be great to know the values as the result looks like they worked well.

Not something I have really understood in the ft88ex. I asked about the component values used in the baffle filter. I do not understand your answer, please provide some more context. Skip to main content. I know you said the shipment was delayed due to the Chinese new year.

Oczka on 14 Feb Redefy Audio Industry Participant Posts: Let me bring the whole scale up 5db and you will see that there is significant break up in the 1kHz to 4kHz range. So imaging is improved And check out the csd. Hank Full Member Posts:
