FosiAudio BT30D PRO 600 Watts 2.1 Amplifier, Audiophile Quality Sound, Review, Teardown & Audio Test

[@indianxtremeaudio]

12:50 , The reason why the gain is not much when we set the frequency to low is not actually the problem of amplifier. It is rather the problem of Subwoofer system. If we use Low Fs Subwoofer that actually go down to 20hz easily ,then you would like to set this frequency control to the lowest settings without any issues 👍. Actually we also used to think the gain is not much when using normal (30-35hz) subwoofer, it is clear that the amplifier is running at same level but the subwoofer driver is providing higher impedance under low frequencies hence moving less and producing less sound. however, when we switched to SB Acoustics Subwoofer with Fs = 19hz , it is working flawlessly under low frequency settings. 😍 Also you can check by adding a Filter in Simulation software. when setting it to low frequency, the software simulation also shows decreased overall SPL , that's the standard characteristics of low pass filter.

[@WhatIThink]

Thanks for feedback...I found this problem in all subwoofer circuits. Let me give it different low frequencies and test the output.

[@KunalVaidya]

Superb step and design choice by Fosiaudio, two 3255s without adding max total power as 600 + 600 , They have kept the claim in the low distortion wattage range

[@dilippandey3963]

[@kanaparthisaikiran8573]

Very good representation of the products Bhai and one thing that I appreciate is that, subwoofer channel issue is seen in most amplifiers like xinyi xy-s350h amplifier and you made it better by informing that it's there in this amplifier tooo,we can't get ultra low frequencies properly from these amplifiers.Keep doing more videos keep rocking..

[@fabiogiehl2627]

Tpa3255 much better than tpa3251

[@bijoykalathil]

Thanks for this great review video. Could you please suggest a good active subwoofers to connect with this amplifier... 🙏

[@Technical_Bhaiya]

बहुत ही अच्छा रिव्यू किया आपने

[@MrPhonicOfficial]

nice review . which is better sound quality wise ? fosi audio or sound king ? please reply

[@WhatIThink]

Both are different class amp...depends upon our test

[@ABMUSIC6791]

@WhatIThink how are you Sudhir ji... Nice review as always.. I wanted to have your opinion about the BT20A PRO that I had purchased upon your suggestion, a month and a half back... I did an extensive audio comparison of it with XY-T00L and found that the sinilink amp sounds very well as compared to fosi.. Infact its more clear and the higher frequencies are reproduced much better in XY T100L.. So much so that I have again shifted to it instead of fosi.. The treble response is much better, much clear, much loud yet sweet... I am puzzled as to how this could be... And what are my options to make audio from fosi better so that it suits my kind of taste... I have used same speakers, same volume levels, similar bass and treble levels yet still XY-T00L sounds pretty wide clear and better... Kindly advise Thanks

[@WhatIThink]

Once your ears are trained for high bass and treble then return to normal levels are difficult. Keep away the other amp for some time and use only BT20APro. After a long gap again hear both the amps along and decide.

It would be more like 55w RMS on below 1% THD, To produce 600w RMS would fry this lousy board. To simply give a metered load check at power produced at different OHMS and THD to prove what you are stating. The Manual state Max 165w x 2 At 4Ohms and Sub 350W x 1 At 3 Ohms with 32v 5A provided

I purchased this unit. As per your comments this is not good amp. Generally we us this amp with Bluetooth input. My as per my experience the sound what we get with CD player input the sound we get t volume nob at10’o clock, the sound we get with Bluetooth is equal at 3’o clock. Such a low volume with Bluetooth. It is a mere waste of money . What I think your opinion is business oriented. Already I am returning the unit.
