Ron, BTW, been simulating the 12MU build a little more, a tweak to the LF crossover first inductor- not a big one. 5.6mH to 4.7mH; keeping the original 78uF to ground, I'd go as low as 4.3mH; that can be done by unwinding the inductor; can provide details later about how many turns. Wait until I've really checked all this out- will be fairly soon. I'm going to be doing some correlation testing soon- still, where are you on your component buys?

Sorry to put another item on your plate, Jon. At least it's something you can do without lifting. Speedy recovery.Leave a comment:

Values are correct; I think Darrel caught that discrepancy earlier but I dropped the ball on correcting it... or I reposted an earlier version in starting this thread. Sorry.Leave a comment:

There's a bit of confusion in the schematic with part numbers in the first post. The first woofer inductor is specified as 5.6 mH, but the part number corresponds to 3.5 mH. Assuming 5.6 mH is the correct value the part number should be Part # 266-928.Leave a comment:

This is a new "Evil Design Study" in the old tradition, which will soon be converted to an active project as components ordered begin to arrive...
The premise is quite simple, based on a few objectives which have been prioritized:- Extended LF performance with low distortio

OK - so the bits are starting to fall into place, and I think it's time to start planning my Ardent build:T
Inspiration thread: https://www.htguide.com/forum/showth...sign-and-Build
It's in good time, if you look back I actually started planning my first... -
OK, have the data now for the ScanSpeak 12MU4731- have FRD and ZMA files, too-
First, a composite set of curves at 0 degrees, 15, and 30:
Here's the impedance curves- point to a fairly clean motor with good inductance control:

So after many many months of talking about building a pair of Wavecor Ardents and collecting many of the parts, I've finally come to the point where some actual progress on the cabinets is being made. This thread will track the progress of my build, however don't be surprised if my build goes a bit... -
Im interested in building Wavecor Ardent, Statement II, or Bordeaux. I'm assuming the best would be the Ardents. For those of you who have any of these, how do they stack up against high end commercial speakers? My favorite speakers so far have been Bowers and Wilkins 800 D3 Diamond. They are around...
