Awesome! Thanks for posting pictures :-)
The tuning for the 7,5cubic feet enclosure will be aprox. 40hz, similar to the Everest DD55000...
To achieve this, the ports have to be about 3,5" long and 4" in diameter.
I donīt like the plastic-ports so I milled some solid walnut ports out of some well dried slabs.
The ports have to be glued together out of to slices, as these are only 2" thick each...
Mounted in the enclosure it looks like this:
Amazing wood work

Has an interesting Aquarius II-vintage vibe going on...
Actually I havenīt been aware of these speakers at all, but I totally have to agree with you!Has an interesting Aquarius II-vintage vibe going on...
Funny, I thought I had a glorious idea to make a big speaker look more slender, but Iīm decades too late with my idea
Wow, Doc! Those walnut vents just look FANTASTIC! Great work, my friend.

I will build the passive crossovers for the 2405 & 2446 (2441 diaphragm) compressiondrivers according to the 3155 equivalent crossover network.
It has the required xover frequencies of 1,2khz and 10khz and is highly regarded on this board.
It had been puplished by 4313B .

The crossover for the E-145 will be similar to the JBL 3120 network.
http://www.jblproservice.com/navigat...chematics.html
The coils are pure copper AWG 6 (3,9mm) air-core-inductors.
They are 1,5mh (milli-henry) and weight several pounds
This is the lowpass crossover for the E-145.
Donīt be confused, the big inductor/coil is mounted seperatly due to the high weight!
The circuit board is based on epoxy and very resistant and none fragile.
All screws are pure brass and non magnetic or inductiv.
Capacitors are Mundorf MCap and MCap ZN.
Resistors are non magnetic and non inductiv from Mills.
This whole project is amazing. Art from end to end.
Thank you for taking the additional time to share with us.
Barry.
If we knew what the hell we were doing, we wouldn't call it research would we.
No kidding!! Great work.
Iīm glad you guys enjoy it, thanks a lot for your kind compliments!
Is it possible to fall in love with speaker ports? Amazing, best I've seen anywhere.
Hi,
I Only do not agree to run the midrange at 1,2Khz as high pass.
this is a 3 way, why you want to run the E145 till 1-1,2Khz??? This make no sense.
You have the opportunity with your horn and 2446 to go down to 400-500hz and let the voice not to be in the Really critical "1Khz zone" where the final result will be a Giant and not realistic voice.
You have not a 4 way with a midrange..........so use as much as you can the Compression Driver from 400 to 10khz. (I'm telling that to you because before I had a similar system with my 2441).
