Hi all,
I have finally gotten around to cataloging and photographing most of what is left from ACI inventory. There is quite and assortment of drivers, accessories, cables, and even some unique electronics. I'm posting it here first. In my dream world, one of you would want the whole lot and be willing to drive to Western Wisconsin to pick it up at a great price, or meet me close to Western Wisconsin. Next best would be someone wanting it all and willing to pay to have it packed an shipped. However, I will sell and ship small groups of items for the right price etc. But no, I won't spend an hour packing something up for $10 that is going to cost $7 to ship. I'm not going to set a minimum order, but it has to be worth my time. So here is the list, PM me with offers or questions. You can google for most of the specs. I'll individually list some of what I think might be the most interesting items first. Thanks!
EAM (Environmental Adapter Module) is a very precise room equalizer. These units had an original build cost of over $300 each and were hand assembled in the USA. MSRP was $1299. The cost of just the chassis and power supplies were well over $100 in quantity. You could use them to install your own custom electronics. I have 4 of these

DH Labs D75 Digital cable. This sold for $7/ft in bulk. I have a 1/2meter finished with RCA and a 45 foot section and 170 foot section. You could certainly make some money building up some custom cables.

Posting some pics for items that have been asked about:

how much are you asking for the EAM?? interesting piece!
-
Yep, definitely an interesting piece. Email sent. . .
-
I notice that the text descriptions of the switch positions do not match the drawings for examples 3,4 and 5 for the EAM unit instruction sheet.
Otherwise this looks like a pretty useful device.
Do you have spare analog boards remaining? These and a BOM could be useful to do it yourselfers or perhaps even a link to the gerber files for it if you want to be generous.

Just found an in the box, brand new set of Atlantis SBF speaker stands, black, 16".
Will take $50 plus S/H OBO for these: SOLD
Here's a link to what they look like (mine are black , not silver)

Hi Frank! Sorry I missed your post till now. I don't have any other documentation on these otherwise I'd be happy to share. Yep, I think they could be a pretty useful device for very little money.

A few pricing notes, all prices plus shipping (negotiable) :
On the EAM (EQ). I have four, they originally sold for $1299 msrp, build / parts cost was over $300 each. Will sell for $50 each OBO, or all four for $200 shipped in CON U.S.
On the DH Labs Digital cable, originally sold for $7 ft in bulk, $69 for 1/2 meter finished. Will sell the bulk lengths for $1.50 ft OBO, will sell the 1/2 meter for $30 including shipped in CON U.S.
On everything else, make me offers, thanks!

Taking a long shot here...
Any of this still up for sale?

THat pic is from Mike s garage her in La Crosse. If i remember when i went through most was gone. Not sure if MD moved fulltime to Florida or not. He may check in here, but most i gone.. JP

Hey JP, long time! Actually moved to North San Diego County almost 4 years ago. Hope all is well!

Mike....very long time. It's great to hear from you....even though you've turned to the dark side in San Diego. :wink: (Encinitas? Escondido? La Jolla -ho ho?) I couldn't wait to get out of there and into Oregon.
-
Damn, Mike. I bought so many great drivers from you back in the day, it killed me when you went clear and found sanity! You were a mainstay back in the day along with Pat Snyder at SpeakerLab were gurus to many of us now geezers.
I still use Pat's cascaded crossover topology to get very low distortion tweeter networks. Brilliant!
You guys were instrumental in the establishment of the DIY genre and geezers like me are forever beholden. Thank you and God Bless. :thumb:

Dark Side, actually Vista sandwiched between Carlsbad and San Marcos. Too sunny to be dark:)

Is cascaded crossover technology a fancy phrase for series crossover?

No. If I weren't "Restricted" I could post a schematic for a 3-way cascaded crossover. Since I can't I'll do my best to describe it.
Instead of all of the elements being star wired, here is the scheme: the midrange circuit input is wired into the circuit after the low-pass elements. Obviously, computed bandpass components won't work, so the values have to be adjusted to achieve proper summation. Likewise, the tweeter circuit input is wired to the output of the midrange. Again, juggle the values to get acceptable overall frequency response.
The obvious advantage is additive attenuation to the midrange driver and tweeter resulting in either: tremendous power handling or much lower possible crossover points and very low distortion.
It is, however, not for the faint of heart because the necessary values are very different from a star wired parallel crossover. I hope this makes sense.

Seems to be a series crossover as indicated in these diagrams but with a midrange and a tweeter cascade?

https://www.tubecad.com/2017/11/blog0403.htm
Close, but no. The individual crossover elements are parallel connected after each LC section with no series interconnections:
Woofer - LC section with the MR bandpass input paralleled with the woofer.
MR - CL/LC section output with the Tweeter input in parallel with the MR
I know it sounds (and arguably is) arcane, but this type of crossover results in extremely low IMD. It IS a pig to optimize component values, but is worth it IME.

Mike, a bit off-topic but in case you're lurking, a belated THANK YOU for the decades of enjoyment that I have gotten out of my Sapphires and Titan.
These speakers were a perfect match for my conrad-johnson CAV-50 (and for other amps since then for that matter), and will certainly be put back in to service when I get that c-j back up and running.
No reply necessary or expected, just acknowledgement that your speakers not only offered tremendous value, but NEVER got outclassed by any equipment that they ran with in my systems.

Hey Jeff, appreciate your posting this. Put a very large smile on my face :D
