Love the new sound :D

The 1501AL-2 is faster, with at better kick, not much, but enough :bouncy:

The change in the crosover ( idea" stolen" from Vivaregina, 3 Ways to climp Everest ) makes a nice improvement on the horn.

smoother, and less metalic sound.

Cant stop smiling :D:D:D

Cant stop smiling :D:D:DCongratulations on getting those woofers and making the upgrade. In some ways it’s subtle and in others it really isn’t.

Congratulations on getting those woofers and making the upgrade. In some ways it’s subtle and in others it really isn’t.

Thanks Widget.

It was not easy to get them. :)

Do you know if these new x-overs in the 67000, is worth changing?
Or is it a waste of money? :dont-know:

[Titanium Dome]

Impressive effort!

I'm glad to see you made it a two-man job, or maybe three persons including the picture taker. No one wants to see "Crushed under his Everest II" on your tombstone.

I made it a two-man job.
The third person is my wife, taking the picture of me, on my way down, and into the speaker :D:D while she is shaking her head
thinking : My good he is crasy.. :rolleyes: :banghead:

Or is it a waste of money? :dont-know:That’s a tough question... equating additional cost and improved sound quality.

Aside from that, I can’t really answer the question as I still haven’t installed my DD67000 networks because of the wrestling match you are now aware of! :banghead:

That said, since the original DD66000 woofers have a rising response that the DD67000 woofers do not, I have to believe you (and I for that matter) should change the networks. I also believe the newer networks also offer more finesse in the upper midrange. Your network tweak will help, but I think after going this far, these drivers deserve going all the way.

So you have the networks, lying, waiting to be installed.. - nice :D

How much af the network do you have? If I may ask :)

Is it the complet network incl the new levelcontrol, without the batteri?
Or is it perhaps "just" networks for one woofer, and the midt horn?

I believe that the major difference is in the two midt networks - or am I wrong?

[Mr. Widget]

I have all of the DD67000 boards, wiring, and the level adjustment panels for the front. Once everything is installed these will be DD67000s. I just haven’t dedicated a weekend to tear into my speakers which are virtually always playing.

There are quite a few changes between the two networks. Both are available on line for review, you should compare them.

Will you be selling the "old" woofers?

If you do not adapt the networks accordingly, this upgrade might very well be a downgrade, I think.

Not to my ears.
To my ears it's a clear upgrade, no doubt.

What do you mean by that?
Are they avaible for sale online?

[Mr. Widget]

Not to my ears.
To my ears it's a clear upgrade, no doubt.To mine too... though I am using an analog PEQ to make a minor EQ adjustment in the lower midrange.


What do you mean by that?
Are they avaible for sale online?I meant the schematics are available. You would need to build them.

Why not upgrade tweeter and ultra tweeter?

Hi Brian,

It seems to me that some coils are not mounted as usually suggested.

I think ivica is right, I believe one of the 2 coils on a board should be turned by 90° so that they don´t line up anymore. The coils will manipulate each other the way they´re mounted now.

I am not sure what you meen ?

The filters are original 67000 filters.
And I can se that the placement of the coils are basicly the same as the 66000.

"Crushed under this tombstone" is the desirable form for the true Everest 4x or 6x hobbyist EOL, i would think :confused:


Rgd the networks, i think the components look OK with regard to coil cross-interaction (if not, where?), but improvements in component quality like Brian did for the bass units are also possible on the networks. At least measurable. If the listening experience improves that way is a very different question...

When doing multiple driver swaps one might want to consider making a template like the factories use. A simple sheet of hard plastic with the bolt patterns enlarged. Place the woofer into the cabinet, place the template over the woofer and then have it with the screws. I consider myself pretty handy with tools but sometimes Mr. Murphy show up.
