I have one of these. Cost £82 from fosi direct with the 48V supply 😊 it's very good for the money. Earlier today I played most of dj dropping bass arsenal album at very high volume on my tower speakers with Zero thermal issues or notable distortion.

14:00. The passthrough allows you to use either the RCA or the 3.5mm as input. It is essentially a Y cable

[mistersunny]

Your Mini Amp videos are one of my favourites as well. I´m somehow always very interested in these devices. Please keep on doing your fantastic job, pal!

[Guiltless]

Still running my Crown Xli 1500's from back when they were 180 ea. Your test on those were great.

The "Pre Out" 3.5mm jack is wired in parallel with the RCA jacks -- this is the same arrangement as in the Aiyima A07.

[Natetron]

I always wonder about these little units and this one did well all things considered. I appreciate you taking a look at it and the video was great!

[lazzzzze]

Thanks for the review and tests. Can't wait to see the next iteration from Fosi and others. Seems like things keep getting better and better.

I have them Elacs (Tower version) in my Home Theater and absolutely love them! Upgraded everything around them but not felt the need to upgrade them yet. Fantastic bang for the buck!

14:50 That all sounds correct for 48v 20a at 2 ohms. It is limited by the power supply max current and the resistor settings for the chip. You might have better luck at 2 ohms with the power supply set to between 32 volts and 36 volts and max 20 amps.

[alexkay]

Interesting But you might want to try Thicker gauge power wire when connected to lab power supply as the thinner factory wire may limit current and therefore power .also with the pre out you use the volume control on Fosi to set the balance / level between the mains and the sub and use to music device to raise /lower volume

[ianvannoort]

that's a really sweet looking subwoofer! I love thos kinds of subwoofer with that huge inverted dustcaps

[TheXxRenzxX]

For your bench supply, id suggest getting some 5525 connectors with screw terminals on them. You can use 14AWG wire with them and improve your results futher. I found in the past that the voltage drop across a 3ft line of 20AWG is pretty significant at 6+ amps. Hope this helps!

I actually bought Fosi Audio BT30D Pro after seeing other models on your channel, I chose BT30D Pro because it has a powerful sub channel and can also be used with active subwoofer and run at 2 ohms

[JustRelaxCo]

Bro!!! You’re like right down the road from me! Love your channel man!!!

[themadmallard]

thx for the tour, its funny what design priorities have done. Of course most home amps are receivers where the power supply is incorporated in the chassis, because of whatever reasons led to the standard stereo component being that big.

the only problem i've had with this crop of mini amp is the pot used for volume goes crunchy within a year of all the ones i've tried....

[jamesplotkin]

Those teeny-tiny power supply wires must be holding back current. I'd like to see if there's noticeable voltage drop at high loads.

[Douglas_Blake_]

I see a common mistake in these comments about the power leads for these amplifiers.

These amplifiers are NOT for cars and they are NOT for driving super-bass rigs in your basement. These are a home HIFI amplifier for use with your PC, record player or, more commonly, your TV set.

The thing is that everyone is estimating the power leads as though the amp is going to draw it's full 20 amps continuously.... But that isn't how music behaves... The average power is actually quite low, even though you are occasionally clipping a snare shot or explosion sound.

With only a 10db dynamic range in your music that 200 watts dyno measurement drops all the way to 20 watts of average power... At 20 watts on 4 ohms that amplifier will draw about 2 amps from the supply. (and make sound loud enough to damage your hearing)

There is no reason to wire it up for 200 continuous watts unless you intend to power a siren.

Fosi Audio TB10D 600W TPA3255 I recently bought this for a bass shaker. Works incredibly well. Nice Bang for buck

[chrisallen]

They need to come out with monoblock mini amplifier’s already.
