Nobsound NS-03G サブウーファーアンプ 100W ミニサブパワーアンプ (ブラック)

Quality and build is good.

Não liguei ainda o amplificador porque ele veio sem o AC 19V que é uma dificuldade encontrar . Acredito q isso não estava ‘ avisado ‘ . No mínimo o vendedor deveria deixar mais explícito como também aonde encontrar um AC correto e compatível.

Using this to drive a Dayton BST1 pro 50W RMS bass shaker via a 90W PSU. I can confirm the bass shaker is operating at capacity. Nice punchy performance and the shaker does get warm. I'm running it at max volume, I'm satisfied the amp does deliver on stated peak power judging by the bass shaker performance. I'm using Simhub so can't comment on the low pass filter performance right now but it's good to have if you are using the game audio directly to drive the bass shaker.

If you're looking for an affordable subwoofer pre-amp to replace a busted all-in-a-box home theatre system to power your subwoofer and give it some more life (like I did), this one fits the bill. However, you'll also need (1) DC power adaptor (my old Lenovo laptop power adaptor works with it); (2) a 1/8" line-in (you can get a cable that does the RCA-out to 1/8" in on Amazon too) and (3) remember to turn on and off the pre-amp separately. If you switch off the main power without first turning off the pre-amp, you may hear a soft "woof" or "boom" - forums out there say it's due to the relay circuits.

NOTE: This is for woofer speakers that are not amplified and where your main amp does not provide an amplified woofer channel. This amp is doing a great job with the woofer of my sound system! The clarity is awesome and the volume is more than we need for our room! The pricing was very affordable. A couple of things for buyers: This amp requires a separate power supply - the list clearly says this but, of course, I missed that. You can use your own power supply, but since this vendor has a cheap power supply that works, I ordered it and it was there the next day - great service! Easy to setup the amp and power supply (took like 2 minutes) and the bass sound is outstanding! For tech geeks only: the instructions and the website have one MINOR spec contradiction: The amp supports woofer speakers that are as low as 2 ohms and as high as 8 ohms of impedance. The instruction page that comes in the box says it only supports 4 ohms to 8 ohms of impedance, not 2. I talked to the firm and 2 ohms is the correct spec
