DIY Project May (Type) Discussion

The completed speakers will look very similar to this... not quite the DD66000, but certainly no slouch either.

I like them Widget, Yeah!

What happened to the plans to make a "B-design" with 2234's and 2435 without the supertweeter? It was thought to enable us DIYers to build one also if I remember correctly.
I was also searching the private forum for final network design but couldn't find ??

[Mr. Widget]

We need to finish the "A" design first... the final, final networks won't be dialed in and posted until the final cabinets are constructed.

Thanks Widget!

I think you understand the common interest in a B-design with available speakers.
Due to the absolutely strange JBL behaviour it is close to impossible to get the K2 woofers, midrange drivers (ok, we have the 2435 ) and supertweters in USA or Europe.

I'm a registered JBL-Pro dealer and you won't guess that I'm unable to find out where I can buy a pair of 4348 or 4338 since 3 weeks now. Unbelievable!!

If this journey goes on my next speakers will have the excellent Usher 15" woofers.

The REAL problem is getting the K2 or equivalent horn.

Guido: Try 2452H-SL on your PT waveguides....

It can be done
We need to solve the copyright problem but then maybe Widget can help.

I need the horn from 700 Hz upwards

Start with 2352, then, or something a TAD different.

Guido - can you get the 4338 & 4348 from a dealer or 3rd party in Japan? We have Japanese members that could help. Or is the shipping too onerous?
Widget - can you tell whether both 1500's are planned to run in parallel up to the midrange xover?

We ran them passively that way and also in a manner similar to the new DD66000. Both versions had their benefits and problems. Once we have a completed system we will likely revisit both ways and finalize the design.

1. I WANT JBL at least to informe their representatives that there is such a speaker. They shouldn't get this information from customers!

2. I expect the speakers to be available here! The trouble of bringing them to Germany is not my problem.

I can tell you that there will be no further anwers to my questions. They are bothered here. And this is what pi$$ people off.

We'll stay with the vintage stuff ...

Guido,

- Based on my experience with ME150H woofers / I'd recommend using them as 1500AL substitutes .

- The ME150H continues to be available from Harman US for just slightly less than the 1500Fe. At a retail cost of the 2226H , it happens to be a real bargain for a very viable, SOTA woofer ( plus it's an aquaplased cone ) .

The 4348/4338 I try to find for a customer. But they way harman behaves is a mess. They are unable to sell them "for a cool xx.xxx Euro" as they don't even know these speakers. No more comments necessary.

Regarding your woofer advice:

I have 2 rough plans for my perfect speaker:

1. 2 woofers + horn design similar to project may but w/o the supertweeter.
Woofer candidates: LE14H-1, 2234H or maybe the ME150H ? Also I think about the Usher Studio 15HM
Horn: H9800
Driver: 2435HPL

2. similar to 1. but a wooden westlake clone with 2441. If a Be Diaphragm or the original Aluminium or Aquaplased types is not decided yet.

[Skoda]

this may be way out of left field but... why not use a 15" GTI sub? it has a freq 16hz-1k not sure if its the same as the 1500al but it will get you to your 800hz cross over point for a k2 project, and I'am positive they share the same technolgies as well to some point

just a thought

Cheers

Guido,

I sympathise with you. I had to bring a pair of 4338 in myself. Harman UK want to charge 16,000 Euros for a pair of S4800 (Japanese Price 8,000!)

I have 1500AL's. I have H9800. I have 435AL. I cannot get any supertweeters or 435BE without making another trip to Japan. It's really ridiculous IMO.

Whilst moaning, if I stick the 435AL on the H9800 and mate it with the 15000AL, any ideas on the forum for a supertweeter that's readily available?

I don't think you'll need one.
But if...these are a nice tweeters. You can purchase them from me if desired.
