Cone break up adds a ringing as stored energy that continues to ring long after gountek original note has ended. Sorry you list me there. It’s really hard to hear those differences because they are at such a low level.

Sorry if it is in the graph. Fouhtek impedance looks good and is free of any box resonances. Here is the frequency response measured in Jeff’s box. 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 Richie on 14 Feb IOW, the shorter the traces on the Z axis that appear to come off the page foubtek, the better. I know you said the shipment was delayed due to the Chinese new year. You may also like.

As that lower distortion will equate to cleaner sound. It will add a little residual ring to everything.

Redefy Audio Industry Participant Posts: I for one appreciate it very much. Jeff, Danny is saying that the shorter the decay time, the better.

Based on the off axis measurements, I should have the speakers turned to face me, correct? People who bought this also bought. Danny Richie Facilitator Posts: This keeps 1kHz range and above from being pushed forward in the sound stage.

Then, I will compare them to the LGK’s. I am still trying to get my head around the waterfall graphs.

Fountek FR88EX – ” Full-range

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 cr88ex. Great job on the grill. Fr88ec you flip back and forth from the first csd posted then you will see that the range from 1kHz and down is up now.

A couple of questions: Cookies help us provide you a better browsing experience. 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.

This is where the rubber meets the road though. I learn a lot every time you post something like this. It is like looking at the second csd response that I posted that looked really scary and having that graph from 1kHz and tountek, but having the results of the first one from 1kHz and up.


Here is a csd response. That is typical for any driver used in a small box. Danny, Thanks for the info! A 5db reduction in output means it didn’t play near as loud and wasn’t as excited.

Let me bring the whole scale up 5db and you will see that there is significant break up in the 1kHz to 4kHz range. This is easy to hear. Oczka on 14 Feb Stored energy or cone break up is very easy to hear. I am just about to build a pair to this design. And this little driver clearly has some issues in that department. These high-performing cone drivers feature thin-foil fr88xe diaphragms that shed resonance rapidly, for exceptional detail and smooth frequency response.

Hank Full Member Posts: This will help the sound a lot. I have my LGK foutek pack from Ben and I am ready to start building as soon as you have the drivers available. The top of this peak is where the computer sets the 0 on the scale. Would you care to share what values you used for the baffle filter? Fr88ed More Show Less.

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

I can’t wait to install the baffle step loss compensation filter to hear the difference it makes. So imaging is improved And check out the csd. There is an expected baffle step loss below 1kHz.

I do not understand your answer, please provide some more context.
