Funnily enough I own the scan 10f and 602000, they are both exceptional little drivers as long as you don’t try and push them too hard 👍🏼 The 10f is good at 400, better at 500 for me, and the 602000 is a superb tweeter, very detailed for what is a reasonable price... but I think I’d put the sb rdnc ahead of it in value for money

the utopia midrange should be pushed close as a pure midrange, but maybe not so close if used at a lower crossover which I think the utopia can make use of

I’ve heard some of these. I’m guessing after tuning differences won’t be apparent until you push the limits. 🥡🍿🍿🍿

First let me make this disclaimer. I am not experienced at writing speaker reviews. However, I have the rare opportunity to write my opinions on a handful of drivers I have been interested in so I thought I'd give this a shot. If you have any words of advice for me or creative criticism I would appreciate this.

I've had ScanSpeak Discovery 10F midranges installed in my car for about 4 months. I have them mounted Left, Center, Right for the front stage. I also have two 10F's mounted in the far rear D-pillars as rear fill. The fronts are currently paired with ScanSpeak Illuminator D2004 tweeters and Dynaudio MW182 midbasses. The entire system sans subwoofer is powered by a Helix V Eight DSP amplifier. The 10F midranges sound pretty good. However, you always wonder if you can do better. For instance, I vaguely remember how much I liked the ScanSpeak 12M Revelator midranges I had installed in my last vehicle. Sadly those won't fit in my new car without a significant modification so I decided to try the 10F's instead.

I started to search for deals to come up on midrange options I was interested in. I managed to score the Dynaudio Esotan MF171 first. Then came a deal too hard to pass up on Focal Utopia 3.5WM's. Finally I snagged a set of Dynaudio Esotar E430's. Yes, there are other options I would like to try. However, I have a lot cash currently invested in midranges so decided to stop here for now.

You'll also notice that I have three different tweeters in the mix. ScanSpeak Illuminator D3004, Dynaudio MD102, and finally Dynaudio MT171. My primary goal is to evaluate the midranges. However, I will mix and match tweeters as well just to see what I like best.

Sadly by the time I had all these drivers in hand the weather started to get too cold and rainy outside to swap them in and out of my car. I have a small detached garage which is not heated. So, I decided to move My evaluation inside. Perhaps this would be better. I can test the speakers under a more controlled environment.

All speakers will be mounted to a 12"x12"x1/4" MDF baffle. Why this? Well, I had a bunch left over after building stuff for my vehicle this summer :). I painted the front faces in flat black to give them a fancy appearance 🧐.

286443


The baffles will then be mounted to old 6x9 wedge enclosures I had laying around. The enclosures internal volume is roughly 4 liters. This should be large enough not to affect response of the midranges at the crossover point I chose.
286444


286445


Midbass duty will be covered by Boston Acoustics ported 6.5" speakers that served as surround channels in my kids gaming home theater.

286449


And finally sub duties will be covered by a Dayton Audio 12" powered subwoofer.

286454


Music sources will be from FLAC files ripped from CD stored on my laptop. Data will be sent to an off board Motu M2 audio interface.

286461


Finally, midbass, midrange, and tweeters will be powered by a Zapco DC Reference DC650.6 DSP amplifier.

286462


This is kind of a hodge podge of stuff. However it is effective and sounds pretty [email protected] good.

I decided to use the DSP amp so I could properly level match drivers and attempt to set the same house curve between all of them. This way I could ensure i am comparing apples to apples.

Dynaudio E430 and MD102
286463


Scan 10F and D3004
286465


Focal 3.5WM and Scan D3004
286499


I will add response for the Dynaudio MF171 and MT171 once I tune them.

Note I chose a rising bass response as I would in a car.

All speakers were crossed over the same. Subwoofer lowpassed at 80Hz 24dB/octave. Midbass from 80Hz to 400hz 24dB/octave. Midrange 400Hz to 3KHz 24dB/octave. And finally tweets 3KHz and up 24dB/octave.

When is the test being done?
I've done some initial listening sessions already (I spent a month with the Focals). I have a standard music set I'm using to compare. I'll start publishing impressions once I finish supplying background info. I expect the listening sessions will get more detailed and may last several weeks. After all, I just hooked up the E430's late Friday night.

Thanks Ge0 I love stuff like this. I'm in the same boat, running 12m's in my car and always wonder - is the next step worth it ? There was an old mid range comparison done in conjunction with this site back in 2013 where a group compared several mid-ranges ranking them tier 1-5. The 12m's were the only mid range ranked 2 and the Esotars were the only ones ranked 1 I believe. Uh oh now I might have influenced the jury outside the courtroom. What I'm mostly intensely interested in is how the Utopia's sound. Clearly the 12m's are no slouch (although I'd still be running my Satori MR-13P if I could fit them easier) but I have always been intrigued by the idea of moving up to the exotic level (not that the 12m's are cheap) and both the 430's and the Utoopia's are in that tier, althugh truth be told I'm holding our for the Accutons if they ever become available.

In the midrange test I did, both the 12M and e430 were in the top tier (and the only ones). I didn't have the Scan 10F or the Utopia, obviously. I tried obtaining the utopia available at that time but the distributor was very adamant he didn't want the Focal included.

Jerry, don't expect me to be anywhere close to as detailed as you guys were in that review. But, I will do my best. If anyone has anything specific they would lime me to try I will consider.
