Nobsound 100W Subwoofer Amplifier Digital Power Sub Amp Audio Mini Bass Amp with Power Supply (Black)

This thing is tiny; about two inches wide and an inch tall. I took mine apart and mounted the front panel and circuit board into a speaker cabinet. Along the way I noticed that every component was very good quality and the workmanship overall was superb. I cut a pair of wires going to the back panel and was a little sad because the soldering to the rear connectors was so nice.Sometimes I hear a slight burr from the subwoofer I built. I can't tell where that originates - could be the speaker, could be the amp, could be the overall design of the cabinet, or . . . not sure yet. So I did not rate sound quality for that reason. But judging from the workmanship, I am guessing the noise I sometimes hear isn't the amp's fault.

100 watts...sortaThe included power brick is not powerful enough to push full output. You need to find a 24v supply to get there.Thinking they were trying to extend its life with the brick as the amp gets warm under a full load at 24v.The lows are muddy without tuning. A crossover with eq or digital eq solves the issue . Even audiophiles could probably get behind this little amp. Its good for small to medium rooms like an office or bedroom, I could see an OK application in some home theater setups.Overall a good buy

I did not expected this unit to be so small.After connecting it the second surprise was how well it worked.I’m not a supercritical audio expert, but I was educated about base soundas a base player in earlier years and my friend who is an award winner sound techat Public Television. You will not be sorry with this unit.

Overall: Very disappointed in my experience with this product. The unit kept cutting out, I assumed a poor power connection. I opened the unit up (I know voiding the warranty, but the sticker was already peeling off so why not... maybe an easy soldering fix) and found that some of the pins on the volume control pot were not even soldered to the board. Nice design overall, someone put a lot of work into making this a nice package... but if the mfg doesn't solder the pins in, well, you get the idea.After repair, I am happy to report the amp works perfectly now, but what an ordeal. I guess I could have always sent it back for another.

As soon as I turned it on it produced a loud humming noise. Returned it for a replacement. It arrived the next day which was great. Now I have to test the replacement.

works well but the 3.5mm jack is the real downfall. Just like headphones when it moves it can crackle and buzz. would have been a better design consideration to have an RCA jack on it like all American home audio equipment.

plate amps are so expensive so I took a chance and am just as surprised as I was after I got a Nobsound bluetooth amp for my patio. They both really sound great. I have the sub amp connected to a 10 inch Monster home theater sub and gets down to 20 hertz, better than a pioneer sub I had been using

I have left over passive subwoofers from sound systems and bars I have had in the past. Since bigger av receiver require an active subwoofer for the preamp sub out, this works perfectly. Most houses, 100w is plenty for a sub. I plan on adding a mounting bracket to place on back of subwoofer.
