DIY Everest DD66000....finally

[Guido]

Are those black mundorf caps bipolar elkos?

Yes!

Only present in Sub and LF network. As in original Everest.

Except Sub network all CC'ed. As in original Everest.

The blue jumpers are there to adjust Sub and LF level.... As in original Everest.

Nice, I've never seen mundorf bipolars, might use them some day since now I know of their existence. This forum brings perfection out of people. Whenever I see neat crossovers I hope and crave to attempt equal visual niceness.

I hate and love to lurk in your thread - loads of inspiration.

Here are the curves for on axis and 30° off axis FR.
Green 0°
Orange 30°

I also added Impedance curves

...... Can you take some measurements from the guest room please ?

[hwirt]

OMG! Guido that is fantastic, thanks for the pictures.

[Guido]

For those irritated by the high resolution of the curves here is a "brochure like" curve.
10dB scaling
1/12 smoothing

Sound is wonderful. Still no cc battery in place, so it will be smoooother.

Absolutely wonderful Guido!

Congratulations Guido, they look quite nice in your room. Two comments:

Are they toed in enough? (OK that was a question.)

And second, As I look at my pair I think it odd that Ashcraft didn't make the UHF tweeter module the same width as the inner die-cast black section of the mid horn. On the factory DD66000s the tweeter modules is slightly narrower. On yours I see that you made it slightly wider... seems to me the lines would be cleaner if the black tweeter and horn sections looked like a single projected arc.

I am not suggesting you change yours... just noticing.

Tiny details like that aside, your set up and speakers looks very nice... I hope you enjoy the system for many years to come!

In answer to Widget's questions / comments:

>>Are they toed in enough?
The horn has the most regular frequency response when the listener and the 2 loudspeakers form an equilateral triangle, i.e. when the listener is sitting 30° off axis.

>>I [i.e. Widget] think it odd that Ashcraft didn't make the UHF tweeter module
>>the same width as the inner die-cast black section of the mid horn.
The upper horizontal line in the drawing below marks the transition from the inner die-cast black section to the lips. That horizontal line is also a tangent to the UHF module.
