Nobsound G2

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.

I'm using this with an S.M.S.L. A300 amp to hook up a passive subwoofer to it's line-level sub output. It is working perfectly for my needs. PLENTY of power output (I've got the volume set to about 1/3). This devices cutoff of 300Hz is plenty compatible with the 100Hz of the A300. I did notice that in theory the sub freq knob should be able to go down to about 1/3 without impact, but I notice the difference in sound far before that, so I assume it's a non-linear scale. Not a big deal, but might be nice if the knob was labeled in some way so you knew what frequency you are dialing in. That being said for the price I cannot complain. Note that if you are using this for a sub amp be sure to select SUB rather than PBTL with the second switch. If you select full range (PBTL) it has a drastic impact on the output. Which is a BIT odd since I'm already sending only 0-100Hz to the unit from the SMSL. NBD since the SUB setting is most correct for my use anyway, but something to be aware of if you hook it up and think it sounds... off. Quiet. Dont take my minor criticisms for anything but that: nitpicks. I love the amp and am completely happy, especially for the low price.

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.

Nobsound G2 Subwoofer Power Amplifier Mini Mono SUB Amp 100W PBTL BTL Bridge Home Theater is a decent solution to your subwoofer's faulty motherboard. The good; brings sub back to life. The bad; not the same as your Klipsch on-board amp. Good for 12 inch subs, but does not offer the heavy thundering base of 15 inch subs. It's more of a "hitting" base rather than a "rolling" base that rattles the house and vibrates things off the shelf. Arrived in manufacturer's box unsealed but so far so good. Definitely above what I expected. If you have say a 7 channel at 75 watts it'll definitely match up good. However if you're into your base with a more elaborate set up you might want to step it up. Good enough for movies... etc. I can recommend this item. We'll see if it can last as long as my Klipsch integrated amp.

Its crazy that this small thing makes such a powerful sound output. Definitely recommended

I have an older Bose Audio system. My Yamaha receiver didn't have the connections I needed for a sub so I got this to allow my sub to hook up to the receiver. Easy adjustments for the volume and freq cut off. My receiver auto powers off after a certain time but this stays on 24/7. No issues at all.

For the cost, size, and weight, this little amplifier is amazing. I use it to power a bass shaker mounted to a drum throne and the power is astonishing.

Bought it for my Buttkicker Gamer 2, it's better than the original Amp the Buttkicker comes with TBH. Good product.
