Douk Audio Nobsound G2 100 Watt Subwoofer Amp; Home Sub Bass Power Amplifier; Full Frequency Mono Channel Power Amplifier; PBTL/BTL Bridge Amp; Gain Control; with Power Supply

Good power. Using to drive a twin driver passive subwoofer

If you are a sim racer or flight simmer whose Buttkicker Gamer amplifier finally gave up the ghost, look no further. I bought the Nobsound G2 to replace my failed proprietary unit, and honestly, I wish I had done it sooner. The Highlights: Power to Spare: Despite its tiny footprint, this little mono amp puts out plenty of "kick." I was worried 100W wouldn't be enough to drive the transducer, but it handles the Buttkicker Gamer shaker with ease. Built-in Low Pass Filter: The SUB mode switch and frequency knob are game-changers. I can dial in the crossover (40Hz–300Hz) so it only shakes on the low-end thumps and engine rumbles without that annoying "chatter" from high-frequency game audio. Runs Cool: Unlike my original amp which used to get quite hot, the G2’s aluminum chassis stays relatively cool even after a 2-hour racing session. Compact Design: It takes up about a quarter of the space of the original BK amp, making it much easier to mount or hide on my rig. Setup Tip: Make sure to flip the switch on the front to "SUB" (not PBTL) and check the gain switches on the bottom. I set mine to the higher gain setting to get the maximum punch from my LFE signals. Bottom Line: For a fraction of the cost of an official replacement, this is a more adjustable and reliable solution. It saved my haptic setup from the trash heap!

Amplificador clase D de buena calidad; sin embargo para sacar el mayor provecho se requiere de una fuente de mayor voltaje y a corriente para aprovechar la máxima potencia, cumple cabalmente, el nivel de audio es aceptable si se poseen los woofers adecuados, buena compra.

サブウーハーとの併用でButtkickerの重低音振動ユニットを以前から使用しており、 振動ユニットのみ単体のサブウーファー用アンプで駆動していましたが、 元ソースとして使用しているAVアンプのLFE（※低音域効果音チャンネル・通常は アクティブサブウーファーの駆動用に使用）ライン出力が低いのか、 ある映像ソースでは丁度いいのに別のソースでは目一杯ボリュームを上げても 殆ど反応しなかったりと今ひとつ安定せず、かといってAVアンプのLFEを弄ると 今度は全体的な音のバランスが崩れるという、どうにも決まらない状況でした。 こちらのサブウーファーアンプも基本仕様は元々使用していたものと殆ど一緒でしたが、 入力ソース側のゲイン調節が可能という点に惹かれて購入。デフォルトより１段低い 入力ゲインで設定したところ、従来のサブウーファーアンプでは殆ど反応しなかった 映像ソースで振動ユニットが反応し、元々が丁度よい映像ソースでも音量ボリュームの 可変範囲で調整可能と、まさに狙い通りの効果で上々の使い勝手です。

After over 7 months of owning this, I have to write that this is a Great! addition to my setup. I have JBL ten year old full range speakers that I use for the mids and highs. I got these with an old Compaq desktop back in 2002 and still works. The Nobsound G2 Sub Amp is pushing a 250W Dual Voice Coil Subwoofer that I took out of my old Hyundai. Let me tell you this little amp is Loud and provide respectful bass. I believe you can even have a decent party on a 12ft x 12ft dance floor with this set up, larger if enclosed. I usually use this on my laptop while working so it is at a fairly low level, though it can be heard throughout my brick house, bass and all. Let's get to the bass, I listen to Soca, Reggae, Rock, Jazz etc. and the bass is decent in all genres. I suspect some level of equalization is used because for that amount of deep bass, I can't see this small amp producing this. The, what appears to be a low pass filter adjustment can produce bass from punchy to deep and I use this depending on the genre I'm listening to. Punchy for jazz and rock, deeper for reggae, dancehall and reggaeton. I would recommend this amp for rigs such as mine listening as levels such as mine. I'm not going to push this loud for parties, I don't think it would survive long but it does a hell of a job for casual listing. I like that I could listed to music across the room as most computer speakers are "near field" and only sound good when sitting near to the speakers. With my setup, this Nobsound provides good sound for a small price. Get it.
