Scanspeak 10F/8414G

This might be my new favorite fullrange driver! Quickly put one in a small box to see, quick measurement 20cm on axis and 30 degrees. Look how well controlled the 30 degree off axis is -

Will put the other in a box tomorrow and see how it sounds.

Those are great drivers, that line. I've heard them in a speaker that was developing nicely.

Wow, John, that's a pretty nice looking graph for a full range. I need to hear these. Keep us posted on how they sound.

Yes, very nice drivers. Plus, they're cheaper than the 8424/4424.

I'm using them from ~300 on up in my desktop setup and am rather pleased.

Very light 3g cone, looks good driver for nearfield FR or match w/a woofer.
The fiber glass cone looks news to me.

Hm, Troels had a good writeup on it. He was impressed:

$65 USD each from Madisound. (In case anyone was wondering.)

Wow. That 30 degree plot looks super nice. ScanSpeak. 4" is an exceptionally "correct" size for a wide ranger, it is the Goldilocks Zone for sure. Nice Q. We look forward to your follow on assessments. I have been thinking about a small, infinite TL, (sealed pipe) for something like that, something modern, useable as mains, and easily put N Sync with a little sub. Please keep us informed!!

Very nice! What is the driver underneath?

£43 GBP each (excl VAT) from Willys Hifi

I believe they come in matched pairs. My two have the same serial number, and measured response is very close.

My measurement yesterday of the off-axis was a bit optimistic... not sure if that was the close distance (20cm) or because I hurried too much. Here's a more careful measurement at 50cm, gated at 2.5ms (still some early reflections off the stand), no smoothing - 0, 15, 30, 45, 60 degrees (red, purple, blue, orange, green). (*)

[Edit] I've revise the graphs to only run to 24 kHz.

For comparison, a Fountek FR89EX (4 ohm version) in the same box (*):

Aurasound NS3 (different box):

For good measure, Jordan JX92s:

(*) It doesn't matter for these measurements but 10F and FR89EX have some BSC (inductor||resistor) in the box.

Hi Dan, I think these are really more like a 3".

Fountek EX89 plot certainly illustrates what I am hearing. They, in the Serene Talismans need to be listened to well off axis. Great mid detail and projection on good material however. I think the Scans would be a few orders of magnitude better, and just enough bigger to shift more air.

Really good size driver for mains for a nearfield/midfield FAST set up, in a real world sized room. Only 14mm greater DIA than the Fountek. 12mm wider cone DIA. Not alot, but still significant, I think.

The Popsicles™ live again!

These originally had TB W3-881s in them. I lent them to a friend and she must have used them as party speakers because they came back trashed. Poor little things. The 10Fs fit easily in the hole although the rebate is too small. Good enough for a quick tryout. Good so far!

May be how they end up. We'll see!

What exactly the "1" vs "2" signifies in 10F/8414 vs 10F/8424 I have no idea. I suppose the G10 and G00 make a difference too.

planet10 · « **Reply #17 on:** 17 Sep 2016, 08:46 am »

8424 has a bigger magnet and does not do as well as the 8414 at being a full-range. We have the 10F/8424. Optimally fits into a 0.8 liter miniOnken.

It's the Seas L16RN-SL, same driver as used in the LX-Mini. I'm running them sealed in the 0.25 cu ft PE cabs, with a powered sub taking over below ~70Hz.

Interesting. I made a mental note of Dr Linkwitz having commented at a gathering in NorCal that he was "thrilled" with the performance of that 6" driver.

Please tell us how it does in the PE cabinet. Seems like it might make a seriously sweet small bass enhancer, which is what I am after, fairly soon.

The Mini-Onkens look good. Small, effective, and portable. Are the plans available?
