      aisa nhi hai ke class D amp low frequency zada acha deta hain, class D amp ka circuit design hi asli baat hain, baat yeah hain ke kisi class D amp ko kitne zada switching frequency(oscillation) pe operate kiya jarha hain.. jitna zada high switching frequency(oscillation) pe class D amp ko drive kiya jayega bass ke sath sath wo utna acha high aur mid bhi deliver krega.. so class D ka main funda uski circuit design pe hain, jitna zada high switching frequency(oscillation) pe usko drive kiya jayega utna clear aur mid high bhi bttr ayega aur efficiency increase hote jayega, example TPA3251 ic 600Khz switching frequency pe chlta hain aur TDA7498E ic 400Khz switching frequency pe chlta hain.. so ptanhi yeah sare hand made mosfet wala class D board kitna switching frequency pe chlta hain..?

      May be you are right per frequency me kuck Hdz ka up down hone per mosfet turan short ya open ho jate hai jabki AB me aisa nahi hota jo punch AB ka hai wo D me bilkul nahi ye mera personal experience hai . Maine Class D 900 watt aur 1800 watt dono use kiye but dono jaldi hi faulty ho gaye . @@bongobarta1908

    Class TD Amplifier Circuit Aya hai ... Class TD ke Sound Quality Same Class Ab Wali .. Class TD kr Efficiency ClassD Se Thori Si kam hai or
    Class H or Class Ab Khi jada hai .... Class TD Amplifier me Mosfets or Transistors dono ka Use hota .... Class Ab Or Class TD me Sirf Ek Difference hai..
    Class AB me Plus minus Dc voltage Direct Transistors k Collector pe D jati hai .... Class TD me Ek Mosfets ke Though Mosfets k Source ke output Transistors k Collector pe D jati hai .... Sirf Ye He Difference hai ..... Class Ab Amplifier me 5200&1943 ka 2 pairs 200watt Se 300watt Deta hai ..... Class TD me Ek pair IRF260N Mosfets ka or Do pair 5200&1943 K 400watt se 500watt Rms Deta hai ...

      Exactly, higher the frequency higher the resolution, or in class d main frequency Jayda nahi hota 100-200khz isliye low frequency ke liye better hota hai high frequency ke liye nahi.

    Mere पास क्लास AB और क्लास D दोनों हैं सही बात ये है कि class AB की आवाज treble bass mid तीनों तगड़ी आती हैं
    Class D में bass quality AB से थोड़ी अच्छी आती treble थोड़ी कम अच्छी आती है।
    200+200 वाट के दो mono AB बोर्ड सेम स्पीकर सेम पावर सप्लाई पर चलाए गए तो अच्छा लाउड साउंड था सीरीज बल्ब 200 वाट का जला था जो ट्रांसफार्मर की सीरीज में लगाया था लेकिन 400+400 watt class D को चलाने पर series बल्ब नहीं जल रहा था। अब खुद ही अंदाज लगाओ कि आउटपुट दमदार किसका है।
