Меленькие динамики...

странное место для темы, она в "очумелые ручки просится"
попробуй в какой-нить студии набрать серединок от штатки, во многих машинах там 2,5-3,5 дюйма бумажные, правда часто двухомные...

В наши студии если кто-то и приезжает, то менять то, что уже даже хрепеть перестало...

мне сейчас такие идут из китая, цена копейки и бесплатная доставка:

  MUSE i15w TA2024 T-Amp Super Mini Stereo Amplifier 15WX2 Board
  

  • Super compact size:
    Dimensions (L)100mm x (W)60mm (Does not contain prominent）

  
  
  

  • 
    The MUSE T-Amp is a so-called Class T integrated amplifier, based on the TA 2024 chipset. the chip makes use of a kind of "Digital Power Processing", this is, more or less, a Class D amplifier with high rate switching properties. That is why they put the word "digital" into it. Actually, there's nothing really digital inside, not in terms of D/A conversion. You can view the official TA2024 datasheet, with detailed tech specs, The MUSE T-Amp is nothing else than a pure and simple
    Class T Integrated Amplfier
    1X3.5 Inputs
    High Quality Components
    Bridged Output Amplifier
    specifications of the IC :
    T-Amp IC Tripath TA2024
    Output Power 2 x 15W @ 4ohm, 2 x 10W @ 8ohm
    Signal-to-Noise Ratio (SNR) 98dB
    Dynamic Range 98dB
    IHF-IM Distortion 0.1% @ 1W, 4ohm
    THD Distortion
    0.03% @ 9W, 4ohm
    0.1% @ 10W 4ohm
    0.1% @ 6W 8ohm
    10% @ 23W 4ohm
    10% @ 13W 8ohm
    Power Efficiency 81% @ 15W, 4ohm, 88% @ 10W, 8ohm
    Input Sensitivity 200mV
    Power socket (5.0mm/1.6mm) x 1
    Output
    Speaker OUT (Left) x 1 pair (+ / -)
    Speaker OUT (Right) x 1 pair (+ / -)
    Power Indicator (RED LED) x 1
    The machine is BTL output, that is to negative side of speaker out is not public grounded (the two speakers cable must independent connect, no grounding together), we must strictly in accordance with the marking of plus or minus cable connection, this T amp is not recommend for car or bike use, if the DC volts input higher than 12.6V or we may damage IC. If the damages are caused by non-attention on instructions all fees need to pay for maintenance.

никаких даташитов по ним нет и никогда не будет

Не знаю как там с data, но shit вполне вероятен

Ving-ving, по фоткам - разводка платы "лишбыкрасива", видимо даж не заморачивались

да пофигу, посмотреть хотя бы, что продают, не сомневаюсь что 50% от всего заказа в помойку полетит ))

тут попались на глаза такие штуки на местном форуме - приколюха америкосов из Aura Sound однодюймовый широкополосник, или длинноходный низкий твитер для низкоиграющих нигеров

вот мануал - вроде они
