2 sw-12” subs or 2 10” Monoliths for a home theater?
A shopper
on Dec 23, 2021
BEST ANSWER: That’s not even a fair comparison. The monoliths are by far better. The SW 12’s are nice but more for a budget minded person.

The 2 sw 12 is much better for base and sound.

two many variables for a definitive answer to this question but going with the 12" sub will provide the most flexibility.

To anyone that has this does it actually sound like 400 watts rms?
A shopper
on Nov 23, 2022
BEST ANSWER: My 12” does not sound like 400 watts. My neighbor bought the 10” and it sounds great with a Yamaha receiver. I think my Yamaha receiver is the problem with mine. I cannot access the setup to turn up the sub. The sub sounds good turned down low. If you turn the volume up much the sound drowns out the sub.

It absolutely does. Even at low volume the clean, distortion free bass hits hard.

It's a single RCA cable that goes from the lowest RCA connector in the MM5s to the input of the subwoofer. https://www.monoprice.com/product?p_id=2683

Is the 400 watt Power Rating a Peak/Dynamic Rating or is the Sub 400 Watts RMS? It sure would be nice if that was somewhere in the description but im guessing thats a "peak" rating so thats why its conveniently left out.

Are you really ever going to get this back in stock? The date used to say May 2023 and now it says June. I need to know whether to wait or if it has been discontinued and I should just buy a different subwoofer.

Adds a whole dimension to background / low level music
This was recommended by the NY Times. I'd not heard of Monoprice before. I bought the SW-12 to upgrade an older stereo 2.0 Bose system that had a non-powered subwoofer.
As my Sony amplifier had only "speakers out" (no dedicated sub or audio out), I tried that first. The SW-12 manual indicated that choice was the least desirable, and it was correct: performance of the SW-12 was mediocre. But I subtracted 1 star for that.
So I then got a new Onyko amp with dedicated subwoofer output. A huge difference! Really deep, feel-it-in-the-chair bass. But bass distribution throughout this large room was not uniform. I needed to move it about 20' to the back corner.
But hardwiring was a problem. So I got the DYNASTY WSA-5TR bluetooth for subwoofer device. Wow it's very good with no perceptible latency. So now I have the original Bose non-powered sub in the front of the room, the SW-12 in the back, and uniform bass throughout the room.
Now if only all my music was equally balanced!

I am very happy with my dual SW-12
I purchased two SW-12. If I compare them with my old subwoofer (a Sony), I can very confidently say that SW-12 is a superior sub. No distortion, very clear and powerful. It does not go down to 10 Hz (I do not care, and it is unnecessary), but above 25 Hz, it is excellent. I connected them to Pioneer Andrew Jones floor speakers. Pure joy.... Also, the shipment was fast, plus, when you call monoprice, you talk to a real person :-)

Glad I bought it.
Larger than I expected but I found a place for it. Not the easiest to set up with a new receiver/tuner but once my son got it set up the sound has been great and what I expected.

I had apprehension from a
1st thing is I purchase two of them. Wow!! what a great balance POP to my existing old 2005 system. This subwoofer has to be dial into whatever system you have, and results are great sounding subwoofer. No don't just buy one of these bad boys.. Buy two as a set. trust me you will not regret it at all. I used Anti-Vibration Isolator Pads Heavy Duty Blue EVA Pads to raise them even higher off the floor. If the port is pointed towards the floor, raising the sub. will give it even a greater effect. This sub is one bad Sub. Even better then Polk audio psw505 which are twice and a half more expensive.

No idea how they do it
I?m not an audiophile but usually have a rather expensive taste when it comes to audio equipment. I bought this subwoofer only as a temp solution because I actually want to buy an expensive DSP-Controlled woofer. But I desperately want it in white and that?s hard to get. Now that this woofer is so good I?m wondering if I should just stick with it and repaint it. No idea how they can sell it at this price point without going bankrupt.
