Fountek’s FR88EX full range driver features an attractive thin-foil aluminum cone, robust cast-aluminum frame, and an optimized high-strength neodymium motor. Fountek FR88EX 3″ Full Range Imp – 8 ohm Fs – 95Hz Qts Vas – L SPL – db Price break in quantity – call FR88 EX Data Sheet. I recently purchased Fountek FR58EX and FR88EX full-range drivers. The packaging box of each model contains a pair. ‘Matched pair’ is.

This is actually typical metal cone issues. Stored energy or cone break up is very easy to hear. Show More Show Less.

Rockford Fosgate T 3-Way 6in. I fountel forward to ordering them. Based on the off axis measurements, I should have the speakers turned to face me, correct?

I do not understand your answer, please provide some more context. People who bought this also bought. The impedance looks good and is free of any box resonances. These high-performing cone drivers vountek thin-foil aluminum diaphragms that shed resonance rapidly, for exceptional detail and smooth frequency response.

I hope that helps a bit.

The top of this peak is where the computer sets the 0 on the scale. Danny, Thank you for taking the time to measure my speakers and for the very detailed explanation of the results. You mention a small inductor and resistor but it would be great to know the values as the result looks like they worked well.

If there was just one measurement that you can do that fr8e8x tell you more about how a speaker will sound it’s the cumulative spectral decay. This keeps 1kHz range and above from being pushed forward in the sound stage. I learn a lot every time you post something like this.

The off axis response looks pretty typical of a small driver too.

A couple of questions: 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 will take some time and study them. It will show you stored energy or ringing issues over time. I got them from Madisound. Here is the effect of Jeff’s grill.

Not something I have really understood in the past. IOW, the shorter the traces on the Z axis that appear to come off the page are, the better. This is where the rubber meets fr88ed road though. Would you care to share what values you used for the baffle filter? For some reason a lot of people have been lead to believe that these stiffer cones will have lower distortion. Cone break up adds a ringing as stored energy that continues to ring long after the original note has ended. So I added a small inductor and Mills resistor to this as a baffle step loss compensation filter.

Danny, Thanks for the info! Jeff, Danny is saying that the shorter the decay time, the better. And here are the two speakers.

I have my LGK flat pack from Ben and I am ready to start building as soon as you have the drivers available. What is the angle fr8ex the different measurements on the off axis measurement? It will add a little residual ring to everything. 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.

A 5db reduction in output means it didn’t play near as loud and wasn’t as excited.

Sorry if it is in the graph. So it induces less ringing. Tuning frequency is just over 65Hz. It’s not bad actually. Then, I will compare them to the LGK’s. In short, at the same output level the ringing will be less sever.

Danny Richie Facilitator Posts: I know you said the shipment was delayed due to the Chinese new year. 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.

The lowest-priced brand-new, unused, unopened, undamaged item in its original packaging where packaging is funtek. It is taking a long time rr88ex go away.
