There is actually a peak in the response above 20kHz that shows up in the csd. No ratings or reviews yet. It’s not bad actually. So I added a small inductor and Mills resistor to this as a baffle step loss compensation filter.

What I don’t do is put forth time and effort into my design work then give fe88ex information away for free so everyone can buy their parts elsewhere. I can’t wait to install the baffle step loss compensation filter to hear the difference it makes. This keeps 1kHz range and above from being pushed forward in the sound stage. Here is a csd response.

fr88ez The lowest-priced brand-new, unused, unopened, undamaged item in its original packaging where packaging is applicable. 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.


I ofuntek forward to ordering them. Jeff, Danny is saying that the shorter the decay time, the better. A 5db reduction in output means it didn’t play near as loud and wasn’t as excited.

If you flip back and forth from the first csd posted then you will see that the range from 1kHz and down is up now. This is actually typical metal cone issues. Cone break up adds a ringing as stored energy that continues to ring long after the original note has ended. 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.

Concerning other full range speakers, fpuntek you accepting orders for your new full range driver yet? Danny Richie on 14 Feb I know you said the shipment was delayed due to the Chinese new year. I asked about the component values used in the baffle filter.


The off axis response looks pretty typical of a small driver too. I am still trying to get my head around the waterfall graphs.

Danny, Thank you for taking the time to measure my speakers and for the very detailed explanation of the results.

This item doesn’t belong on this page. I have my LGK flat pack from Ben and I am ready to start building as soon as you have the drivers available. This is where the rubber meets the road though.

It’s really hard to hear those differences because they are at such a low level. Not something I have really understood in the past.

Sorry if it is in the graph. Oczka on 14 Feb That is typical for any driver used in a small box.

I for one appreciate it very much. Rockford Fosgate T 3-Way 6in. This thin design has a very minimal effect on the response. So it induces less ringing.
