Hi guys, I planned to buy extreme 2, but yesterday I listened to m-video and were not even impressed, I also listened to a boombox, he liked the sound more, now all in meditations in boombox is the only thing that strains this size and weight, although from the other side we don’t have to carry around all the kebabs by car, there is w-king s9 for walking. Takvot, two questions, was still in Eldorado, listened to extreme 2 there so he almost didn’t swing at all under equal conditions with the same column in m-video, maybe there are some modes that include, so she doesn’t scream and go somewhere else to listen, or to score and take the boombox, it still sounds better even without the power connected.

only boombox. or extreme 1. 2nd for home, the sound is lost on the street. I have everything. boombox super.

Hello friends! Only, just brought the 2nd extreme. Unpacked, turned on, listen. While I can't vtopit because they are sleeping at home and the dog is sleeping in the room =) I don’t see a forum for him. More precisely, how. I see it in Google, but when I try to go to it, I write a “mistake”, so I’ll ask here. It seems that after several pages I realized that the owners of the 2nd are here. While there were a few questions. Voiced below.
- The first. Do I need to warm this acoustics? In the sense that someone writes that after warming up it starts to play better, someone that makes no sense. As it was in your practice. Write down please, I will be grateful =)
- Second. There is in stock Flip 4. So. Feels like flip louder. Che for what for? Yes, until I drowned it at all, but at a low (one division) loudness, the flip is heard well, and the extreme barely mumbles something .. And from here one more question, to the owners of the 2nd extreme. New firmware has arrived. 2.0.0.0. It is now worth 1.2.0. Firmware for January 25, 2019. Is there anyone updated? Is it worth it? What is new in essence? Sykatno like that.
Thanks colleagues. Peace in the hut to all;)

The second extreme is already another akb, and then there are sofa experiments miscarriages trumpeting nonsense in their reviews. Now there is a battery LG 18650 4 pieces and the scheme seems to be correct. I updated to 2.0 almost immediately and did not notice much of a difference, but I had a maximum of 30 minutes before the previous firmware). In fact, I can say the following, that all these small-sized speakers seem loud, but in fact this is not the case. The sound is quickly lost with increasing distance from it and the pseudo loudness precisely because of the loudness at mid frequencies that interfere with communication. Here on the extreme is a powerful and deep bass and when it plays loud, it does not interfere with communication and the sound does not dissipate like shallow ones. You leave, but the sound does not become especially quieter.

[SBar]

by the way on extreme 2 nowhere could find a description of the firmware. You need to create your own theme anyway

SBar, I was looking for information about the battery and the power scheme for extreme 2, many people write that nothing has changed since the first. You are the first in this thread who claims the opposite. All the same, 15k - the price is not so small to bother with the battery and then look for solutions in this topic. Where did you find the information about another battery and power supply?

[SBar]

Bajo, you can find a video of the analysis of the second extreme. They are few, but they are there and clearly visible batteries and even labeling.

This is not nonsense, see vidos

chpok_tunec, maybe you read my post incorrectly, but indicated that there are now LG 18650 standing there, not the opposite

[Nickneime]

Recently became the owner of camouflage colors. From under the box was the firmware version 1.9.0, the application offered to 2.0.0, updated immediately. After 15 hours of warming up at medium volume, some looseness of sound has gone, now I listen with pleasure to my favorite tracks through ak320. The sound is impressive after the transition from the Chinese barrel organ)

[chpok_tunec]

Nickneime @ 05.02.19, 20:27

through ak320

Astell & Kern 320?, But do you listen through the aux or bt sound impressive?

[Bajo]

chpok_tunec,
So, judging by the video, fixed? There are no reliable and full review plots, there are also few full-fledged reviews.

[Nickneime]

chpok_tunecYes, it is astellkern. Strangely enough, it still plays on the player more than on the smartphone. I listen on blupup, I have not tried it through the line manager, but I think it will be even better through the ugreen cords.
It seems that there are no more troubles on xtreme 2 with controllers, my copy completely goes dead after 2.5 hour charge.

My battery after 3 hours on charge, if discharged before the red light

[Nickneime]

SBarTo be more precise, mine also sits on the charge for about 3 hours. It means it's ok.

[chpok_tunec]

SBar,
Baggio,
Nickneime
I hope corrected, but the trick is not in the fact that the acb has become 18650 (although it is also a plus), the most important thing is that there is a controller with balancing or not, and so on. In extreme 1, there is a problem in WHAT, there is a shitty controller there, and he has one jar or didn’t take care of or reload, and because of this, they have been SURROUNDED due to this. Therefore, it is important that b charging 100% fully passed during the time specified by the manufacturer. AND WHEN YOU, within the framework of a given time, all the diodes are cut down, it means that the controller is fixed and kills provilno.

chpok_tunecOf course I know the problems of the first xtreme. Here is a video parsing and then there is a photo of the battery and the board. Watch from 5.30

[Nickneime]

chpok_tunec,
Suppose, if we place more capacious banks in place of regular batteries, which total exceeds the standard 10k swings, then the result will also be 15 hours autonomy without replacing the controller on the 2nd extreme?

[Nickneime]

SBarYes, it has already been done) There is no sense in discerning the charge, everything is soapy, the quality is not so hot). But still it is interesting that there))
I fixed my charge 2 time to my friend, the throttle fell off inside after a few falls from the bike, now I'm building again, I can't rejoice in my column))
