Rob,

Can you share what Björn have found out about the 4367 construction?

I have the 2216Nd-1, it is in a larger cabinet at the moment. I plan to cut that cabinet down to the same volume as the...

Not exactly what you are asking for but...

D2430k/M2 horn on top in a repurposed cabinet that is there mainly for support.
2216ND-1 in a 6.5cu ft cabinet which is larger than the 4367...

@tommytoa, Do you mind sharing product link to low noise 24v fans? I have problem finding them.

How durable is Osmo compared to say lacquer or poly?

are you doing active crossover with the 4/600? do you have raw measurements of each driver before and after the change?

Oh... Did I mention she is in her 70s? :D

Couple of years ago she came to visit me and we were tweaking my system and she was able to tell differences in the 10kHz+ range (verified with FR...

Do you plan to replicate the height of the L300 or 4367?

L300 is 803mm tall, 4367 is 941mm tall.

4367 height is OK to be used without a stand. while the L300 is 6" shorter, and probably why...

From center of port to side edge of cabinet: 6"
From center of port to bottom edge of cabinet: 5.5"

looking at the FR from other guys here who tried the various 4" drivers on the M2 horn lens, the D2430K isn't that great compared to them, still have a huge drop going into HF that need to be...

If you get this particular brand, which is the brand sold in parts-express, they included a calculator:

Rob, you can find external dimension of the cabinet in the white paper linked to above. The white paper also describe in detail how thick the walls are (1 5/8" for the front baffle, 1" others) so it...

Dual port with flares on both ends. The straight middle part of the port is 3". Total length including flare is 5". The outer diameter of the flare is 5"

Parts express supplier uses the straight...

My mom has a pair in Hongkong. If no one else has gotten to it, I can ask her to measure the port dimensions. The white paper did say 4" and the drawing and text also shows dual flare. Seems like a...

I spent Saturday the past weekend listening to the STX825 horn. On Sunday I put together a temporary mounting for the M2 horn. Both using the same exact pair of D2430K. Unfortunately I only have one...

It is common practice in China for OEMs to "make a few more" or even "make a lot more" after their daily runs for their proper corporate customers. They will sell the extra made ones at local pricing...

If they are legit, they are not even trying. If they actually managed to pirate the speakers themselves and have actual product with their logos, they can at least have a photo of that. But they...

I won't count on it. Look, they also make their own line of pro speakers that comes with with photoshop logos!
...

mortron, great fun to be building speakers. I have started late compare to the more experienced members here. One thing that I have learned is that while some of the older drivers have great...

I got a pair of D2430K and a STX825 horn. Being brand new, the matching of the 2 D2430K are spot on.

I built a little enclosure for the STX825 horn so that I can place it securely. The STX825 horn...

Oh I see. I have the wrong impression that the D66000 horn is actually part of the cabinet and yours came with it. JBL did a much better job with that series in terms of finishing than well......

i might have missed the discussion. But why did you not reuse the Everest horn?

trying to mount/use the 4367 horn in the Everest cabinet will be.... challenging to say the least.

OP's room is reasonably close to golden ratio if he cuts the length to 22 feet long.

Agree, I am sure a lot of us would love to be in the position to design and build a room. Instead, we are just trying to deal with what we have. Personally, I am still fighting my 20x20x9 room which...

insulation / Safe 'n Sound in the wall, floors. Whoever will be downstairs and next door will appreciate it.

JBL drivers are designed to be handled very rough. Those baskets, when not being used in a speaker, can probably take the place of a car jack stand when you need to change the car tire.
