Default Scan-Speak Discovery 10F/4424G / 10F/8424G

Scanspeak Discovery 10F/4424G, 4" Midrange 4 ohm: Madisound Speaker Store
Scanspeak Discovery 10F/8424G 4" Midrange 8 ohm: Madisound Speaker Store

The price is a big turn off. I could have sworn these were around $60 each when I first saw them. Did the neodymium really go up so fast, or was I just dreaming? I sure wish they were cheaper. Why keep using neodymium if it drives cost up so much? On the other hand, the one thing I always want more of with 3" drivers is motor strength.

Cost aside, I thought the results on Krutke's blog looked pretty promising. Looking at Sd, they're really about a 3.5" driver. Has anyone tried these as full-range? Any thoughts on the "coated NRSC fibre glass cone"?

They are indeed great drivers but expensive. The extended and ultra flat Frequency Response paired with the high sensitivity are unbeatable.
I think they work really well as fullranges if you can live with the narrowing dispersion of 3" drivers. You will need woofers for the low end, they are not capable of any reasonable bass.

I have a set that will be presented in the Round 2 of the "Subjective Blind Comparison..." thread. The measure very flat - one of the smoothest responses I have measured in any driver. They are very well built and sound excellent. I have some initial measurements in the TC9FD Best Bang for the Buck thread Vifa TC9FD18-08 best bang for the buck. Right now I am waiting for the highly regarded Visaton B80 to arrive for comparison before releasing the sound clips for Round 2.

I tested the 10F/8424G00.

Specs here:
http://www.scan-speak.dk/datasheet/pdf/10f-8424g00.pdf

It is a special driver so making a box for it is difficult - trying to find something worthy of it. I am basically going to end up with something similar to the FAST setup it currently got tested in. Looking at a short vented TL for the 10F, and an 8in bass driver in either a sealed or tapered vent TL. XO at about 400Hz, miniDSP and bi-amped of course.

I am looking at it to use with a single 8565 for woofer and either ss9500 or possible one of their older d2010 3/4" tweeters.

Haven't tried 10F for me will depend which of 10F/8424G00 or B80 looks best in Subjective Blind Comparison round 2 that xrk971 intend later when B80 arrive.

Below interesting links to confirm their data.

Member wesayso share 8424 data from Klang & Tong Vifa TC9FD18-08 best bang for the buck.

Both 10F/8424G00 and 10F/4424G00 are here go to index at top of thread to see other driver models too and the measurement conditions plus gear used, use of translation could be needed ??-????????.
