Zaimel e398, I do not understand what's good about the dynamics? Well, the vibration echoes .. but the sound in the same 6288 is louder by 30% and purer by 70%, and with bass and high good. Well, no vibra, but not critical. And here it is vybrykivaet but the sound of some mid-frequency. I thought only mine, I listened to E1 the same garbage. My 6288 will be more qualitative.

Ttuner,

Good is just in the vibra. In addition, at that time it was the best quality sound in the phones from the speakers. But you can really feel its power only on patched by sound firmware.
In addition, if these speakers are put on other mobs, they often rock the sound better than the engine. (I remember SX1 ...)

Well for that time of course, but now alas. From a vibe to sense it is not a lot of sense, and the speaker any more is not. Mtorol of course patched at me on a full platform on 373 with all the chips, of course the difference is in the sound of the original, but time goes by

I here a few days ago a good amp made a mikruh TEA 2025, and shoved this beauty into the passive column TOSHIBA SP-10S
[Attachment = "304972: tea.jpg"]
Here is a diagram for connecting danoy mikruhi
[Attachment = "304973: tea2025bav9.jpg"]
But I did not do a bit of this scheme, but by etoy
[Attachment = "304974: TEA2025.jpg"]
In general mikruha stereo but the second version of the connection type "in the bridge" gives twice the power but for one speaker, I also beat the filter added to the input from the annoying hiss when the music on pause.
Koeshno in the phone does not fog, but for the outer column the most it! : Yes2:

[Attachment = "304991: SP_A0127.jpg"]
[Attachment = "304992: SP_A0128.jpg"]
Power from the battery, and charging from the native charging ETEN G500 +. AT)

People! Just buy the speakers of the computer, disassemble the one into which the 230-volt wire goes, there is a converter which with 230V does about 9 volts (on the converter it is written) we remove the converter, connect the acamulator and everything plows!

That's what !? And you think that no one has thought of doing this? Tee first come up with an idea, develop a scheme and a fee, Correctly solder so that all UTB earned and then open your mouth and then dzyavka! Here people discuss what they did with their own hands, and not the Nubian ways to make a Chinese shit candy !!

I did the same before with the Khripelkami Genius. Feeding from the crown was and then from the Akim of Nokiev. I'll say the sound leaves much to be desired. Therefore, I think it's better to find a quality scheme and solder.
