I purchased this sub based on various reviews(Expert and Home Theater Enthusiast) and it didn't disappoint. The sub is pretty heavy so shipping is expensive. It arrived in good condition, excellent protection. I added this sub to my system to get a better seat to seat consistency and I have achieved that. My other two subs are different brand, but they are very similar in the low-end extension and are also front ported subs. The integration of my three subs was seamless and the Monolith M-10 2V blends nice with the other two. The sub quality feels good, it's heave and feels very solid. I like how this sub sounds. It has a very good frequency response. This sub is meeting my expectations so far.

Very happy with this subwoofer. I needed a second one to balance room bass response and I didn't need anything huge, just clean and capable of 20 hz. Shipping was fast and damage free.

I purchased two of these for a small theater room (12x14) that does not have any acoustic treatment. I am using Audyssey XT32 for setup.

Pros:
- Plenty of output for this room size
- Responsive down to 20hz
- Simple controls on the amp make it easy to interface with or without a receiver.

Neutral
- Seems somewhat heavy/bulky for a 10" sub

Cons:
- Significant port noise at 25hz. I ended up having to run these sealed as the port noise is so bad. This seems like a straightforward engineering exercise to address and is a big con to these subs if you're doing HT
- High background noise in the amplifiers. On one of the subs, if I turned the volume up all the way (with no signal cable connected) I could hear a sort of "whooshing" sound as far as 10ft away. In the other, if I did this, the whooshing sound was only audible if you were about 1ft away. Noise seems relatively high on these amps. Does not appear to be power related as the effect was consistent between subs and rooms

All I can say is WOW!! This sub really outperforms my REL subs. I really like how ow it can get, that being said it's rather large so I put it on a furniture dolly to move it around till I find the sweet spot!! If you're on the fence about getting it. Lear's just say it brings action movies to life!!!!!

The plots and the rave are true, this sub is great. I bought one, liked it so much that I bought another one for the living room. I have driven them pretty hard already in testing and didn't reach distortion, clipping or shutdowns.

Do notice that a good sub is only half of the experience, placement and room shape are equally important. I spent several hours trying different locations to find the optimal spot and this is time well spent IMO. I recommend REW + UMIK-1 mic for measuring the room response.

Hope my poor house endures the bass shakes now.

No joke the best sub I've ever heard in a home theater. The quality and shear omnipresence of the bass is completely insane at that price. Absolutely in love with it and can't recommend it enough. I will say... it is pretty darn big, so make sure you have the space for it.

Love these subs! Came carefully packaged and protected. Easy to set up and get dialed in. Provides deep, clear and responsive bottom end. I'm running two of these subs with vintage Klipsch Cornwalls, and these Monoliths sound magnificent!

Sono un perito in elettronica e telecomunicazioni, nonché audiofilo! Volevo inserire un Subwoofer, nel mio impianto, non tanto per la musica, quanto per migliorare la risposta in frequenza, l'estensione e l'impatto durante la visione di film.
Ho creato quindi un impianto 2.1 all'inizio credevo che 500 Watt rms fossero veramente troppi; invece, il suono di questo animale è uno spettacolo assoluto!!
Scende in frequenza con una facilità impressionante, grandissimo impatto e realismo durante le scene più spettacolari!!
L'amplificatore integrato con DSP fa un lavoro eccellente, ottimo il controllo, non si avvertono code o rimbombi, la qualità audio è altissima!!
Completissima la sezione dei controlli e delle possibilità di collegamento!! La costruzione è veramente di alto livello, il peso di 33Kg la dice lunga sulla qualità dei materiali impiegati!! Consigliatissimo!! Non fatevelo scappare!!

I was looking for a budget solution for my living room which I primarily use for 2 channel music listening. Was doing some research online and saw rave reviews for monoprice subs. Had already listened to their THX speaker lineup, decided to pull the trigger on this one. Proved to be a wise decision.

Packs a lot of punch with 500W amp and has a linear frequency response with the lows. It is built like a tank using higher quality materials than some of my existing subs. Thoroughly enjoyable.

The only con is it's a bit clunky, not easy to move this thing around.

Would definitely recommend to anyone..

Works really well in my medium size living room
