Nobsound G2 Subwoofer Power Amplifier Mini Mono SUB Amplifier 100W PBTL BTL Bridge Home Theater

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。

Thunder. For 50 bucks I am blown away by this tiny little amp that kicks out big Power. I hooked this up to a rejuvenated old Panasonic ported subwoofer from a mini home theater system from the '90s that was reloaded with a $30 Skar Audio 6.5 inch subwoofer. The adjustment knob for the bass frequency coupled with the volume knob and the subwoofer/full-range switch on this little Nobsound unit can pump out some big bass from a tiny sub. It's powerful enough that I cannot turn it all the way up and at 50% volume it sounds amazing. The signal is coming from the AUX port of my Fouk Audio mini tube amp. This combination along with some tiny Polk Audio bookshelf speakers sounds incredible in a 12x12 bedroom. Absolute High-Fidelity clarity, rich sound, clear vocals, and thundering bass. This is a great mini system that will sound (and feel) awesome for a medium-sized room.

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.

Cheap, good sound and really fast delivery! I bought a cheap 450W powered sub on eBay but it didn't work. Scouring the net I found this amp and decided the outlay was worth risking on an unproven speaker. I ditched the old amp (but salvaged the banana plug terminals and internal wiring) and hooked up this new amp—needless to say, it surpassed my expectations. TBH, I've noticed the tiniest bit of a hum from it, but I previously had huge issues with a ground loop that made my previous set-up un-listenable. Once I've got music or a movie going, the hum is not at all noticable, even on quiet stuff. From what I've seen, there aren't many other mono amps at this price with a frequency dial. And there's even fewer with a bridged mode (PBTL), not that I need this functionality myself. My only wish is that the frequency dial doesn't have any measurements on it, so I've had to guess where the 80Hz mark is. Finally, mine was delivered next day. Very impressed!

Très bonne qualité sonore pour la musique et cinéma maison. Bonne profondeur et fonctionne parfaitement avec mon sub.

Used this to replace the piece of crap buttkicker amplifier I have for my flight sim chair works 1,000,000 times better then the stupid buttkicker one did.
