That's the nice thing about subwoofers, you can never have "too much" since you can just turn them down.. it's always the case of "not enough".

This is a slim 12 inch powered subwoofer built for tight spaces, with enough output for modest setups and a little extra thump for bookshelves, soundbars, or a bedroom home theater. The low 7 inch height can fit under some regular LoveSac seats, and the compact profile is the main appeal. It is not a high end sub, and the cabinet, driver, and bass quality are described as basic rather than refined. Fit and placement matter, the cable is not included, and the connection options are limited without a sub output.

people trying to add "a little thump" to a modest bedroom or small home theater setup because it's a low-profile, space-saving 12" that should be enough for pairing with bookshelves or a soundbar.
swechsler FranksAndBeans capricio TodayOnly
buyers who need a powered sub that can fit under a regular couch/seat because measurements suggest it should clear under a non-storage seat (about 10" from cushion bottom to floor) even though it's only 7" high.
swechsler
home theater users with an AVR who want to improve bass response because if your receiver has sub EQ it can help address the tendency of cheaper subs not to play very low or very flat.
FranksAndBeans
stereo/2-channel setups where you can route bass to the sub because a stereo receiver or properly adjusted home theater receiver can set speakers to small and feed only bass to the sub for better headroom and dynamics.
hellonwheelz
people pairing with a budget soundbar for a bedroom HT upgrade because commenters specifically recommend pairing it with a $50 Yamaha soundbar refurb and call it a solid upgrade.
capricio

buyers who want to connect using a dedicated subwoofer output from their receiver because this model doesn't have a sub output and is described as direct digital, limiting connection options.
room209
people planning to place it under a storage seat or in a tightly enclosed spot because it likely won't fit under a storage seat and ventilation could be an issue if you put it inside.
swechsler
neighbors/households expecting it to be loud enough to rattle pictures because it should provide some thump but "won't knock the pictures off the wall" in a neighbor's house.
TodayOnly
buyers who need a weather-resistant or outdoor-ready subwoofer because it isn't weather resistant and the setup requires low-level line inputs.
Baron_O_BeefStick
buyers who are sensitive to "cheap/boomy" sound quality compared with a higher-tier sub because one commenter preferred the Monolith M10 V12 and found this one sounded cheap and boomy for their taste.
Brunoslack

The subwoofer can fit under a regular LoveSac seat based on measured clearance and its 7-inch height.
swechsler
The low-profile design targets space-saving setups where a full-size subwoofer takes up too much room.
swechsler
The subwoofer can provide some thump for modest home theater or music listening without extreme volume expectations.
TodayOnly
The unit includes a stereo RCA cable, which can simplify wiring for basic powered-sub connections.
swechsler

The subwoofer does not fit under a storage LoveSac seat, and placing it inside may raise ventilation concerns.
swechsler
The model lacks a sub output and uses direct digital, which limits certain connection options with receivers.
room209
The cabinet construction can feel thin, and the driver may buzz slightly when operating even if the buzz is reportedly inaudible after mounting.

A damaged-in-shipping report indicates the unit can arrive very damaged, which may require returning before use.

Common Questions (5)

It should add some thump and work for modest setups like bookshelves or a soundbar, but it is not a high-end sub and will not deliver room-shaking output. AVR sub EQ can help it play flatter if your receiver supports it.
swechsler TodayOnly FranksAndBeans Brunoslack
It should fit under a regular LoveSac seat if there is about 10" from the cushion bottom to the floor, since the sub is 7" high. It will not fit under a storage seat, and placing it inside one may create ventilation issues.
swechsler FranksAndBeans
Yes, it includes a stereo RCA cable, roughly 6 feet long. The cable is easy to miss in the box, so check the packaging before buying one separately.
swechsler swechsler
It does not have a sub output itself, so it needs low-level line inputs from the source or receiver. For speakers that only output full-range signal, a low-pass filter may help, but the connection options are limited.
room209 Baron_O_BeefStick
Yes, it can be added to a stereo receiver setup by setting the main speakers to small and sending bass to the sub, which can improve headroom and dynamic range. It is also described as a good modest upgrade for a bedroom soundbar setup.

So I can connect this to a stereo receiver by running the existing speaker wires through it?

Yes. The stereo speakers will play the same as before. This will do that.

However, a HT reciever, even used in 2 channel stereo properly adjusted would set the stereo speakers to small and feed only bass to the subwoofer. That improves the sound by increasing headroom and dynamic range of the stereo speakers. And things can get a bit louder without sounding bad.

Under a regular love sac seat, I measured 10" from bottom of cushion to floor, so it should be OK, since the sub is 7" high.
It won't fit under a storage seat, although you could probably put it inside (but ventilation might be an issue).

Is it decent quality? Not looking for a movie / bass heavy music experience, is this a deal at this price to add a little oomph. Any better bang for the buck alternative sub $200?

Biggest issue with other cheap monoprice subs is they don't play very low or very flat. If your AVR does sub EQ then it helps with that concern, and a 12" should certainly be enough to satisfy modest needs like pairing with a pair of bookshelves or a soundbar.

Note the dimensions. It's pretty damn big for one of these, though they are usually 8 or 10" subs. I mean it doesn't matter much as long as it fits under your couch, but the wall mount or under table folks should mock it up.

Pair this with one of the $50 Yamaha soundbars. eBay item number:297670467933

Listed as refurb, but I have bought two of these in the past and they were new/greymarket.

A solid upgrade for a bedroom HT setup.

Cable not included. Best placement will vary by room, there are Youtube videos that will show you the trick of subwoofer placement by listening.

I am tempted to buy this, but I just don't want to buy a sub. I wanted to put under our sectional, but I am always about properly blending a sub in the system and making sure that is doesn't call attention to itself. It's like you no one would even notice that you have a sub.

I received this a couple of days ago and unpacked it yesterday. Haven't hooked it up yet but here are my notes so far:

Construction is just OK. Cabinet walls are thin; there is some internal bracing but it still has a somewhat hollow sound when knocking on the side. It's understandable that it was built this way since they wanted to minimize the height. I personally would have liked to see some more bracing
Subwoofer driver looks like a fairly inexpensive unit, typical of this price range
As many people in reviews have mentioned, it does buzz slightly when on, and the buzzing is audible from a couple of feet away. However (and this is important), the buzzing is well above the normal subwoofer frequency range, and more importantly, when you have the sub mounted on the floor or a wall, you can't hear the buzz anyway.
Surprisingly, it does include a stereo RCA cable, probably about 6 feet. I didn't notice it at first because I had left it in the box with some of the packaging
