Default audiophile midrange ?

Hi Guys, I'm going to be building 12" 3-way. I'm hunting for what might be the nice-est sounding midrange for under $500 usd. I'm aiming to use it 400-4000htz range. I Have limited experience with different mids of this caliber, and hoping some of you can help compare.
- the only mid on my radar so far is the accuton 3.5" (model #c90-6-790 i believe)

-(My previous systems I'm upgrading used scanspeak 7", and dynaudio 6" mids)

For that frequence range you mention, I have good experince with Scan Speaks 4" units, 12M Revelator and 12MU Illuminator. they are very widebanded, and long stroke for a 4" midrange.

If you can "cut" the upper octave to 2 kHz instead of 4 kHz (when considering dispersion), that would be the the BG Neo 10 ("open back").

Here are Dan's "Echelons":

I am using PHL.

High end THD and good efficiency so you can tune it down to what you need in your application.

Hi,

Satori from SB acoustics should be considered. It receives very favorable review from this thread,

The B&G RD-40 is just below 500$, and you'll save money on a tweeter... because you don't need it.

I'm going to endorse the BG Neo10 as well with the caveats:

DO NOT solder, use push on terminals. I'm a very accomplished soldered and even so, it seems I may have hurt a few of mine with repeated soldering. It's the only explanation for why their measured performance has changed so much since Zaph first tested them almost two years ago. My fresh one is perfect, but the three others all have issues. I have never soldered the new one.

See here for measurements:

DO NOT use above 3KHZ and be steep with the xover. There is a resonance at 5KHZ that rings forever. It's not like the sound of a metal cone in breakup, but it's there and nasty if you let it through.

Follow those rules and it's world class used open baffle or in a well damped enclosure.

Greg
