clear DEEP DEEP BASS, LOTS AND LOTS AND LOTS OF BASS for a sub with an 8" cone, plenty of power 120 watt amp, bass that will fill any room, small box 12" by 12" by 12"

are you kidding why would there be any weaknesses on this sub when it puts the same output of a 10 inch sub.
cant relly feel the like the other reviewer below me said put the sub behind your coutch then you can relly feel the bass

tested polk audio psw-350 and klipsch KSW-10 nothing compared to the acoustic sub the amount of bass was not as good as the klipsch and polk but the acoustic was cheaper and put out a cleaner crisper deeper sound but not as loud.
the frequncy's on this sub quickly drop below the 25 to 28hz range .
this sub is great it's small yet has such a good sound .
my friends sub is a Yamaha YST-160 which has 2 8" subs with a 160 watt amp cant compare to my new sub.

Deep, clean bass. 120 watts, As said before, it feels like a 10" - Great value

None to speak of. For the size and price, its near flawless.

Very clean sounding sub. I'm using it with my Kenwood Vr-309 pre-out connected by a 6ft. AR coaxial. (Always use quality cables.) Bass sounds amazing for an 8" and works wonderful with movies. Its not quite as effective with music but it gets the job done. As mentioned before, placement is key. So if you have around a $500 or below theatre system, this sub probably has the greatest value in this price/performance range.

This is a somewhat technical followup on my review from September. There are some corrections I would like to make for my first review. I said you could use the tape monitor loop, and though you can this means you cannot control the volume from your receiver. I had meant to say to use the preamp outputs of a preamplifier like in the manual. Also, I said there was a a high cut filter when it it should have been a high pass (bass cut), though there seems to be a high cut filter as well (very very little midrange output compared to a normal active filter). I'm sure there is a bass cut filter at a frequency at or a tad below what the system is capable of because the driver moves very little below the port tuning, while in a conventional ported setup the driver would move more as it becomes unloaded (at port tuning the speaker barely moves, bass comes from the port mainly). That said, here are some updates for hookup and troubleshooting I have noticed.

As I mentioned before, there is no phase switch. This wasn't a problem where the sub was first used, but when I tried another pair of speakers it was rather difficult. You could fool around with placement to attemp to correct this, but usually most do not have the time or space to do so. To compensate for the missing phase control, use the speaker level inputs. If the phase is a problem, try reversing the wires going into the subwoofer (the sub should be parallel wired with the receiver/amp, if you're using the speaker out reverse those wires as well). Also, the manual mentions that the sub should be parallel wired with the receiver along with the speakers, even though the diagram doesn't show this. This setup is recommended by me as well because I have opened up the sub (hush hush...) and there is a high pass filter on the speaker out terminals. The filter is a 200uF cap inline (6db/octave filtering, frequency depends on impendance of speaker used), good if you have small satelites, but will waste power and prevents bass from getting to your mains. The slot loading works great if you have carpeted floors, which would absorb some of the bass. If you have hardwood floors though, try removing the board, your floor and the sub will make the slot loading and you get added tactile feedback.

The construction and design seems to be a nice compromise. As I said, there appears to be high and low cut filters (a bandpass filter basically) so the sub's amp is only operation within a very frequency specific range. The amp itself is quite small, as is the transformer, but whatever power it has is being used well and the design is quite efficient. The enclosure is a mix of MDF and particleboard (aobut 3/4" thick), it's pretty solid but could be better (no bracing). Though there is little acoustic damping inside (a chunk of fiberglass insulation only), this is a ported sub so standing waves are not a problem. The port is nice and large with plastic flared fittings at both ends. The driver is quite beefy looking from the back too, it is a heavy gauge stamped steel frame with vented magnet structure.

I have compared this to a 10" sub I built. It's a sealed design with eq to boost the low end response. This AR sub compares well, it sounds just a tad slower (it hangs onto certain frequencies a bit, especially near the frequency of the port), but this makes it sound fuller and a bit warmer as well. It can play just as loud and quite cleanly too. I still prefer a closed design for music listening (it can sometimes sound muddy or overly warm and slow), but this is still a great sub for the money and for home theater.

strong base, east set up

no on/off switch

I got a great deal for $118 at ABC Wharehouse in Farmington Hills, Michigan from the manager Bruce; super nice guy. He thru in the y-adapter. Works great even in my medium size room with B&W fronts, yamaha center, yamaha receiver, and sony dvd player.

Auto power off does not work (for me)

Well I was going to buy the AR112PS but my wife didn't like thought of some big ugly thing sitting in our game room so I started looking for a smaller subwoofer. I talked to various people (including Crutchfield) and they all suggested that the small AR unit would work for me. Since the room I was putting it into was rather large (21x16 with 9 foot ceiling) I was skeptical. I shouldn't have been. This baby rocks!

I would like to point out that placement is important for it though. Mine is in a corner about 2 inches from both walls. Here, at about 3/4 volume, my whole room vibrates but the actual sound does not overpower my other speakers.

Very nice unit for the cost (got mine for under $180 shipped).

Available at accessories4less.com w/ full 5-yr warranty but close-out prices (around $140+ shipping).

Very compact unit -- about 12 inch cube.
Has built in volume switch, and cross-over freq. dial to fine-tune the tone.

If you have a mono (single-line) subwoofer output, you will need y-adapter.
