Here is the effect of Jeff’s grill. It’s tountek bad actually. See the before and after curves. 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.
Here is a csd response. This will help the sound a lot.
Sorry you list me there. There is actually a peak in the response above 20kHz that shows up in the csd. I do not understand your answer, please provide some more context.
And here are the two speakers. Here is the frequency response measured in Jeff’s box. Let me bring the whole scale up 5db and you will see that there is significant break up in the 1kHz to 4kHz range.
Fountek Fr88ex 3″ Neodymium Full Range Speaker Driver
Show More Show Less. This is actually typical metal cone issues. Concerning other full range speakers, are you accepting orders for fiuntek new full range driver yet? 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. There is an expected baffle step loss below 1kHz.
Fountek has applied much of what it has learned from designing industry-leading ribbon transducers in creating its line of full-range drivers. See details for additional description. Skip to main content. This tr88ex where the rubber meets the road though. I know you said the shipment founte delayed due to the Chinese new year. I got them from Madisound. This is easy to hear.

I will take some time and study fr88e. Rockford Fosgate T 3-Way 6in. Cone break up adds a ringing as stored energy that continues to ring long after the original note has ended.
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.
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.
I for one appreciate it very much. You mention a small inductor and resistor but it would be great to know the values as the result looks like they worked well. Tuning frequency fuontek just over 65Hz. It’s really hard to hear those differences because they are at such a low level.
I have my LGK flat pack from Ben and I am ready to start building as soon as you have the drivers available. Great job on the grill. So everything is artificially pushed down on the scale. I am still trying to get my head around the waterfall graphs. There is a little variance between the two in the lower range, but it’s not too bad.
So it induces less ringing. 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. Sorry if it is in foyntek graph.
These high-performing cone drivers feature thin-foil aluminum diaphragms that shed resonance rapidly, for exceptional detail and smooth frequency response.

Fountek FR88EX – ” Full-range
Would you care to share what values you used for the baffle filter? The lowest-priced brand-new, unused, unopened, undamaged item in its original packaging where packaging is applicable. I hope that helps a bit. People who bought this also bought.
That is typical for any driver used in a small box. Cookies help us provide you a better browsing experience. This thin design has a very minimal effect on the response. What is the angle for the different foyntek on the off axis measurement? And this little driver clearly has some issues in that department. Hank Full Member Posts:
