This IPPIN guide is the large-sized speaker of JBL. Project Everest It is DD55000. (Satake) EVEREST. It is smart! Large and it has a presence very much. It should be called the big warship of a speaker, Weight is 145kg, And it is a super large-sized class of speaker. (Kondo) |
|
At first it is a front. If we removed the network divided into 2 blocks, we can see the unit group of an excessive design. (Kondo) Special formed HF horn and a unique unit layout make all the space inside a speaker system build an exact stereo image, since it corresponded to the advanced program sauce which will be realized in the further, the dynamic range was also expanded sharply and realized 250w input (it is not believed as that time), and sound pressure also realized 100db SPL (1W, 1m) thing. (Kondo) |

Mr. Satake, I want you to express Everest's this special form from various angles. An inside is also attractive and I am interested in it. (Kondo) It is a horn. It is called a Defined coverage horn. It is said that the angle of 30 degrees is attached to the baffle side. (Satake) |
|
It is woofer. 150-4H. This frame is quite thick. Two bus reflex ports are vacant. The angle of 30 degrees is attached by this unit also. (Satake) |
|
They are super tweeter and an attenuator part. Tweeter is 2405H. (Satake) |
|
If we removed a driver, it is like this. The black curtain is stuck on the part that we see from bussref port. and we can not see the grain. Inside is completely divided into two rooms and if we see the lower room, the cable is only hanging down from the top. (Satake) |
|
Four cables came out from the top, two were connected with the network from the unit, and two are connected with the speaker terminal. (Satake) |
|
This is the backside of woofer. (Satake) |
|
The backside is like this. (Satake) It is unique that the driver has overflowed the box. (Kondo) |
|
We can remove the upper room only by removing a screw from back and the small window is attached to Everest' back and we can immediately touch a network from there. (Satake) |
|
Open a small window, it is a network. (Satake) |
|
You can adjust of a network immediately. (Satake) |
|
If we opened the small window, we can see the strange hinge.(Satake) |
|
If we opened a back board, it is like this. We see the horn is attached with an angle. (Satake) |
|
It is the horn from back. (Satake) |
|
You can see the attachment part of tweeter and attenuator behind a driver.(Satake) |
|
It is the up photo behind tweeter.(Satake) |
|
It is the backside of attenuator. Many codes have come from back.(Satake) |
|
It is the reverse side of the board of a network.(Satake) |
|
It is the hole of the cable from the upper room to the lower room.(Satake) |
|
The Sort part of a horn is horizontally. And the horizontal curve has come out from the middle. The fixed part of a driver is being fixed to the metaled plate. The pillar of middle is made of wood.(Satake) |
|
It is a part of upper saran net.(Satake) |
|
This is under. We see two saran nets are the same, but delicately different.(Satake) |
|
It is the part of a speaker terminal. Since the terminal is small, a thick cable is not in it.(Satake) |
|
This is the side. It is quite thick.(Satake) |

I took up the new audio after a long time in this IPPIN guide. It was like the modern version of D31050 of JBL before I took up in this IPPIN Guide. Although it is a quite novel design, I think that all are calculated and harmonized. Although the last Barcelona had the good design, such a thing does not have this Everest, it is designed only in a function. There is an image of PARAGON. It is thought vision also influences the sound. It is the speaker that overwhelms the people who listened to it by vision and sound. I want to live in a house that I can put on such big speaker.(Satake) It is Everest DD55000 which developed of the consumer speaker exceeding PARAGON and concentrated all the wisdom of JBL stuff. It was born in the careful sound analysis over several years. EVEREST DD55000 greeted by envy and overwhelming praise, It was made minutely and just reached to the top. It had a vast sound place reappearance capability. I want to sound this speaker with the McIntosh MC-2500 or MC-2600 (They are the same aged), if we want to sound EVEREST.(Kondo) |
