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.

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.

good for the price
My only complaint is that the cabinet is not well braced and resonance from the box is introduced to the sound field, but for the price not sure perfection is a reasonable expectation. Good addition to smaller speakers, maybe not so much to full range. Was able to get them to extend down to 28hz before roll off in room with room correction software. Sound good in AV system, decided not to use in 2 channel system.

This is a solid "budget" amp! Loud, clear, and awesome!
I already had this subwoofer's big brother, the Monolith 10". But, I didn't want something that expensive, nor that powerful, for my bedroom system. However, I did want a subwoofer that would be able to handle all the low frequency sounds, plus get a bit loud if needed.
This subwoofer is everything I wanted. First, I think it should be noted that this subwoofer has a very powerful amp which helps a lot! Low bass notes require a lot of energy to push and the amp in this sub is 400 watts, powerful enough to do the job!
It doesn't get quite as low as my Monolith amp does. However, we can't really hear those notes that are that low, but we can feel them. That being said, this subwoofer gets quite low. The specs say it can reach down to 33 Hz which is almost as low as we can hear.
The subwoofer can reproduce rumbles for earthquakes and explosions very well and also handles music with aplomb. I think the sound is not as tight as the Monolith, but its quite acceptable to my ears.
It is ported on the bottom which helps it get those low notes. It has a switch to change phase, too.
Basically, I see this amp as a smaller, less featured version of the Monolith. If you are putting together a home theater and need a subwoofer, but can't afford a Monolith, then this is a great substitute. I recommend it without hesitation to anyone looking for good bass without breaking the budget.
