Monolith M-15 V2 15-Inch THX Certified Ultra 1000 Watt Powered Subwoofer - Low Distortion, High Power Output, Vented HDF Cabinet, RCA and XLR Inputs, For Home Theater Systems, Black Ash Finish

Great build, deep bass. I was impressed that it could be configured with quick tight bass, which is important for music (this was my biggest concern) I added some svs soundpath isolation feet. Love the performance.

A few weeks after ordering, the item arrives. I manhandle this enormous box upstairs and go to great lengths installing it. It turns on but barely a hum. I called monoprice and they said, after multiple tests, that something was wrong with the Amp. No option but to return. Amazon had a curt and poor customer service response, and the agent let me know that after they pick up, which will be not for a week, I will have to wait another several weeks after that for my return to get to me. This is my worst purchase experience on Amazon in the many years I've shopped with them. The item was broken, and the entire process around this defective item was a sour experience. I spend a considerable sum only to have that sum be on hold for over a month. I was considering monoprice speakers next year for home theater and now I probably do not have confidence in their quality assurance.

Waited two weeks to receive this sub only to have it fail to work at all. I see a lot of reviews stating the same thing. It’s not easy getting a 168lbs unit in and the have to send it out. Such a waste of time and effort. Consider another brand.After a couple weeks, I decide to give it one more try. I ordered the same unit it arrived today and it has beautiful, clean, and powerful bass.

The media could not be loaded. I bought this sub for 1200 on sale and I think it’s the best bang for your buck. I’ve noticed you really have to have to have this cranked to notice it. Low volume you really don’t notice it.

Was looking at SVS subs, but after watching many reviews on the tube, decided to give the Monolith a try. Glad I did! It was on sale over the 4th of July holiday week. This sub hits notes so low your insides might rearrange! The way the 15 pressurizes the room, it gives you such a feel of being IN the scene of a movie! 1port plugged, gives great tactile feel without being boom-ey. So great I had to have 2 of them!! AMAZING! At 153 pounds each, plan where these behemoths are going and how they are going to get there.

Got this for around $1,100 they have real Bass, I'm playing them with my BOSE 901, it make them sound even better.

My 6-month-old M-15 V2 has an amp issue. Repeated contacts with Monoprice Support have confirmed that they refuse warranty from Amazon purchases. Dead amp in 6 months, no support.Whatever you do, do not purchase this product. I should have listened to all the reports of bad customer service and poor quality. Now I'm out more than a grand.

This replaced 2 klipsch r12sw's and it hits so much lower and louder. Even after measuring, it was surprisingly big. It is a beast in both sound and size.
