Why add a powered subwoofer?

A powered subwoofer gives you bass you can feel as well as hear. Our customers love the depth and impact their subs add to music and movies. We hear comments like "it brings out sounds I didn't know existed in discs I've watched a million times." Powered subwoofers aren't just for big bass that rattles your picture frames; they can also deliver tight, accurate lows. If you haven't shopped for a powered sub in a while, you might be surprised at how small they get. Look for an ultra-compact model if you want to tuck your sub away under an end table or in a corner.

Subtle and Powerful

Written By plhoward, San Francisco on Thursday, March 13, 2014

Crutchfield Customer Review (What's this?)

I purchased this subwoofer along with the Energy Take 5.0 5-speaker home theater system. The Energy system originally had a subwoofer but was discontinued so Crutchfield recommended this sub instead. And boy do they know what they're talking about. This sub offers the clearest and most solid bass I've heard. Now all sound is subject to the beholder and where it's located but for me this couldn't get any better. I calibrated with with my entire system and it offers incredible low frequency but not over-powering. It balances well with the rest of the speakers. I was just watching the iTunes Music Festival and realized I've had this system for a year and never wrote a review. The entire system makes it feel as if you're right at the music festival. I highly recommend both. Sure, you can find better for more expensive. But for the price, I'd be hard-pressed to think you can find better quality.

Pros: Solid, powerful sound, sleek look

Happy so Far!

Written By DanB, Long Island, NY on Monday, March 11, 2013

Crutchfield Customer Review (What's this?)

So far I am very happy with the performance of the sub. My main reason for getting this particular model was the size of the box and also having 3 power options (auto, on, off). My previous sub (older velodyne which I still love) was not very sensitive to input from my receiver and would not often turn on since it only had an auto on function. The Omni S8 is much more sensitive to input and I have not had to use the "on" function as of this point. I am not fully through the "break in" time of 50 hours, but I will say that the sub sounds great and blends very nicely with my Energy Take 5 set. It produces good bass, but it's not quite as house shaking as something bigger. If you know what to expect from an 8" sub, then you should be very happy with the S8. If I had more room I probably would have gone with something else given the price, but I am happy overall.

Pros: Compact size with good, quality sound which will blend into a small speaker setup. Will definitely fill most any room with full sound, especially if this is the price point/size you are looking at. Good input sensitivity.

Cons: Does not shake the house. Was a little more expensive than similar sized subs.

Excellent sub for music/movies for average size livingroom-- especially for 5.1 encoded shows-- Netflix and Pandora sounds much better with bass presence.

Pros: Easy to adjust with volume and frequency controls on front of sub

Cons: None

A Real Gem!

Written By Troglodyte, St. Croix, VI on Friday, December 21, 2012

Crutchfield Customer Review (What's this?)

This speaker is a very musical subwoofer--better articulation than other subwoofers I have heard. It is also a very good looking unit, and ideal for my small to medium sized listening area.

Pros: Great sound. Very easy to position since the port is floor-loaded. Location of the controls is ideal. Great build quality, especially for the price.

Cons: None.

Superb Small Sub

Written By HDW, Portland, OR on Tuesday, November 27, 2012

Crutchfield Customer Review (What's this?)

Tremendous little performer. I bought a pair of Klipsch G-12 flat panel speakers and I needed a sub to go with them. I was going to get the smallest Klipsch sub, but discovered that it wouldn't fit in the small space I had intended for it. Mirage Omni S8 to the rescue, and for less money, with a clearance of 1/8" on each side, it *just* made it. I couldn't be happier with the bottom they provide, easy low end punch, clean deep bass without being mushy. I've had it for two months now and I've finally got it dialed in... I had started with crushing bass but over the weeks, eased it back some, then brought it back up to find the perfect sound. I very rarely do these reviews, but I'm so pleased with the spectaluar performance of the Mirage Omni S8, it's worth sharing.

Pros: Clean crisp bass

Cons: None

No power

Written By Rich, Sitka, Ak. on Thursday, August 16, 2012

Crutchfield Customer Review (What's this?)

I unfortunately got the scratch and dent model. I hooked it up and there was no power at all. I was told by advisor they are like new with a few cosmetic things wrong with them. That was okay with me, but I wasn't expecting no power. I am waiting to see what Crutchfield will do about this.

Crutchfield response on Monday, August 20, 2012 Our Scratch & Dent models are tested to make sure they are in working order. It's hard to say what went wrong in this case, but we issued a replacement.

Very Satisfactory Small Sub

Written By Micro Seiki Man, Sacramento, CA on Friday, June 29, 2012

Crutchfield Customer Review (What's this?)

I have become an enthusiast of small, powered, "musical" subwoofers to warm the sound in mid-capacity stereo TV and non-audiophile Audio systems. I don't want to shake the windows or scare the pets. I like balanced low-frequency filler sound that can also surprise me with power and clarity in appropriate passages. The Mirage Omni S8 fits the bill perfectly. It produces clear, sharp, contollable sub-bass without much tendency to be boomy. I should mention that I have only used an "LE" connection on the receiver for the source. If I set the sub volume consistent with program content at modest levels, louder passages are also produced effortlessly and in balance with the higher frequencies. The S8 has surprised me several times with the performance of which it is capable, especially for its small size. It may not be "The Bomb", but it's "The Grenade", dude! I think it's perfect for my type of applications.

The first S8 I received had been ordered as "scratch and dent", but arrived in a beat-up box, broken. Crutchfield did not hesitate to replace it at no cost to me with a NEW S8 promptly, while I returned the original one at the shipper's expense. I can't ask for better service than that from any vender. Hooray, Crutchfield!

Pros: Price Size Controls Quality Performance

Cons: Has High- and Low-Level inputs only; there are no High-Level outputs to satellites if desired Requires 50 hours break-in time, such as playing a CD over and over through it, prior to set-up

Holy Moly

Written By Tim H., Freehold, NJ on Saturday, June 02, 2012

Crutchfield Customer Review (What's this?)

I place the sub behind my entertainment center and ran Audessey on my Denon AVR-2807. Once up and running we watched Clash of th E Titans on Blu-Ray and the room was shaking from this 8 inch driver? Wow this thing has even surpassed my greatest hopes even at this price point. Very fast and tight sounding bass with very low distortion, I couldn't be happier.

Pros: Footprint, refined and effortless sound, excellent build quality especially at this price point.


Written By DavidJ, Framingham, MA on Tuesday, April 03, 2012

Crutchfield Customer Review (What's this?)

I bought this sub to use with Martin Logan Motion 12's (great midrange and highs - bottom needs a little help) in my basement 2.1 set up, but decided to "test it" with my main 5.1 system, and now I cant seem to part with it. Playing movies, SACD & DVDA's, CD's - you name it, it sounds great. No subteranean lows, but fast, musical, accurate lows that make everything sound better. Surpassed my expectations.

Pros: Blends easily with your system Accurate, punchy, musical

Cons: Not the last word in really low bass, but hey, its an 8" compact sub!

Clean Controlled Performance

Written By Anonymous, Minneapolis, MN on Thursday, March 29, 2012

This modestly priced sub woofer is perfect for providing the missing lower frequency sound you need. I come from an audiophile background and I notice boom and mud in any sub woofer very quickly. I use a pair of these in a higher end system for both music and film. They are clean, well controlled and blend into the sonic hologram beautifully. Plenty of punch for medium size rooms. Good fit and finish quality. Mirage has a full time staff to answer your most technical questions about this unit. What a bargain it is!

Pros: Enough controls without "over doing" it. Great musicality but up to the task of explosion laden action movies. Easy to love!

Cons: The built in amplifier is 100 watts. Clean sounding, but might need help in a larger room.

An Audiophile Sub

Written By JT, Wilmington, NC on Saturday, March 24, 2012

Crutchfield Customer Review (What's this?)

This is clearly an audiophile subwoofer. Unlike some that offer only boom and no definition, this one is nicely defined, tight and fast. The controls, which are accurate and sensitive, are conveniently placed on the front, saving always have to tilt the unit forward (or move it altogether) to see what you're doing when changing volume or timbre. I have mine running at quite a low volume, well away from the nearest EPOS ELS-3, providing me with everthing I need. The frequency tuning is also quite sensitive, allowing you to dial in exactly where it needs to be. If you want/need it to crank, it certainly will, but I like it for it's delicacy and speed.

Pros: Tight, fast, articulate. Small and easy to place, with conveniently placed controls.

Cons: None

Crutchfield Customer Review (What's this?)

Once again, Crutchfield has exceeded expectations! I have been researching for over one year, not ready to buy until sure. When this MIRAGE dropped to $249- I finally decided to go Mirage Omni S8. Not even broken in yet, the sub provided the "something" I was missing. I have the Marantz SR 6003, (from Crutchfield), the Marantz BD 7004, (Crutchfield), and the Marantz CC4003 5-disc (you guessed it, Crutchfield), and Polk Audio RTi-7's. I added the Mirage Sub, set Fronts "Large", low-pass 80Hz, and phase 0, and sub volume at midway, and WAS DIALED IN. Ziggy from Crutchfield handled my order, and in 6 days sub was found! Thanks to Ziggy, Crutchfield (service extraordinarre), I am enjoying music/movies for a fantastic price overall, with the best customer satisfaction I could have imagined! I will be back to Crutchfield for more, and will tell friends. (My Dad is soon to buy a TV)

Pros: Everything, Crutchfield, Ziggy.

Cons: Nothing

Mirage Omni S8 is a Great Value

Written By John S., Winter Springs, FL on Thursday, September 15, 2011

Crutchfield Customer Review (What's this?)

The Mirage Omni S8 is a great subwoofer for the price. It is being utilized with a Yamaha Amplifier so the crossover is not being used. I only have the S8 on half output and it is cranking out solid quality low frequency sounds. Even at high output, the bass tones are very crisp. Great Product.

Perfect size for my den, has plenty of low bass response and power. Really don't need to get anything bigger or more powerful. Feels very solid and well built. Something rare, not built in China! Actually made in Canada, imagine that. Nice controls, and is easy to set up. Five stars in my book.

Great soundbar combo

Written By Tom, Salisbury, NC on Monday, May 25, 2009

Crutchfield Customer Review (What's this?)

I ordered the Omni S8 to enhance the bass with the Polk Surround 360. I also needed a small footprint because of the layout in the room I was using. I have now passed the 50 hour break-in period and am well pleased with the unit. It does well on both movies and music, I use the system at about a 50/50 split so it does matter that it does music well. I realize that I could have gotten a much bigger sub and rattled the windows and walls but that was not what I was looking for. I am well satisfied with the additional bass this provides that the Soundbar didn't. It is great in combo with a soundbar.


Written By Craig, Lansing, MI on Thursday, November 20, 2008

Crutchfield Customer Review (What's this?)

This sub will fill your every need. As I was shopping I kept telling myself to go bigger and better. I ended up restraining myself and not purchasing the 10" sub. I found out upon receipt of this sub I made the right decision. It has plenty of power and deep lows. Construction is bullet proof and it looks great too. One more plus is it doesn't take up as much space as the 10" would. Save a hundred bucks and by this one, MIRAGE OMNI S8.


Written By David, Los Angeles, CA on Tuesday, July 22, 2008

Even though I am using a 100 watt cheap Sony amp (DG520) for a basic
2.1 application, I've got something really special. I've paired my NANOSATS
with Mirage's S-8 powered subwoofer. All I can say is that this is
absolutely an affordable way to make a small room seem like it's an IMAX.
well, not really, but at least like a much more expensive system. The small
satellites (slightly smaller than non-Lifestyle Bose satellites) put out a ton
of sound and deliver beautiful highs and mids. The lows are booming from
the compact powered S-8. I watched King Kong last night and was thrilled
with the output. Times are tough. Money is tight. If you need to drown
out the outside world, this is a great and affordable way to do it. Thank
you Crutchfield!

Amazing Little Sub!

Written By jrssol1, Bloomfield Hills, MI on Tuesday, December 26, 2006

Just replaced an old Bose Lifestyle system (no loss there) with an Onkyo 703 receiver (great price at Crutchfield), 4 Mirage Nanosat Prestige sats, 1 Mirage Nanosat Prestige center-channel, and the Mirage S8 sub in a 16'x20' carpeted room (13' foot listening/viewing distance) with 8' ceilings that is fairly open to the rest of our medium-sized condo. I have the S8 about 6' away from a corner, 1' away from the cabinet-style tv stand, and less than 1' away from the wall behind it with the front/cone facing the listener. I have all the sat crossovers and LFE low-pass filter set via the Onkyo at 120Mhz (Mirage's recommendation); the sound is very seamless/natural and deep. My ears started to hurt long before I could detect any significant distortion out of the S8 (or the sats). Contrary to another reviewer, there is NO sign of boominess, which might be attributable to placement, crossover, and/or level adjustment issues. Oh, and did I mention that the S8 is very nicely finished and looks great without overpowering the room? I couldn't be more satisfied with this purchase (cripes, even my wife likes it)! Now, if you have a notably larger room, high ceilings and/or like to crank it up to ear-bleeding levels with lots of people yelling/dancing, you may want to consider the S10 or S12.

Good sub, very tight and clean sounding. I purchased the 8 inch version hoping it would fill the sound gap I had in my stereo/theater system. My only complaint is I wish the sub wasn't so boomy when it's cranked up. Otherwise a wise purchase. Crutchfield support is TOP NOTCH as always .

Great little Sub For Small To Medium Sized Rooms

Written By Rick, Lexington,NC on Friday, August 11, 2006

This sub is perfect for small-medium sized rooms. It produces plenty of nice tight,clean bass. It is equally good with both movies and music. It is a very good looking,well built sub. If your room is on the smaller side this is all you need and it would be a waste to spend more on a larger one that you would not be using anywhere near its full potential. Do not be scared off because it only has an 8" driver, it will definitely get the job done. I have it paired with a Harman Kardon AVR 435 receiver,Polk RTi6 mains,CSi3 center,RTi4 surrounds, and a Sony DVP-NS3100ES DVD/SACD player in a 10' X 14' room and I am very pleased with the performance. Highly recommended!

Product Research



Overview: The Mirage Omni-S8 is a compact powered subwoofer that features an 8" woofer and a 100 watt internal amplifier.

Ribbed Elliptical Surround: The Omni-S8 features a woofer with a Ribbed Elliptical Surround, which is a proprietary component that has been designed to increase excursion, eliminate distortion and raise efficiency. This feature eliminates any surround dimpling so this subwoofer can play lower with greater output and fidelity.

Bass Reflex Cabinet: The down firing port of the Omni-S8 increases output without port noise, using the floor as a loading surface to augment the yield of this unique subwoofer which allows the subwoofer to deliver natural and lifelike sound.

Amplifier Section: The powered subwoofer has a built-in 100 watt RMS internal amplifier.

Driver: The Omni-S8 feature a front firing 8-inch titanium deposit hybrid woofer with a ribbed elliptical surround which performs like a much large subwoofer and has a frequency response down to 27Hz.

Status Indicator: The LED found on the front panel will illuminate when the subwoofer is connected to an AC source and when the unit is active. The LED will display in red when the unit is plugged in but is not receiving a signal and will display green when the unit is receiving a signal.


Front Panel Controls: The powered subwoofer uses front panel controls to make it easy to adjust the volume and crossover at any time.

Subwoofer Level: This knob can be adjusted to control the level of output from your subwoofer. The level chosen should allow the subwoofer to blend its output with that of the rest of your audio system.

Frequency Control: This control allows for the adjustment of the low-pass filter. Adjustments can be made from 40Hz to 120Hz. This will determine the highest frequency that the subwoofer will play.

Phase Control: This switch allows for the adjustment of the phase of the subwoofer, in relation to the speakers used in your system. You can choose either 0 degrees or 180 degrees.

Filter Mode: This switch allows for the selection of either "Filter On" or "Filter Off". Choose "Filter Off" when you are using a receiver with a dedicated LFE out that has its own crossover filter.

Power Mode: This is the only control function that is found on the rear panel. This switch can be set to either On, Off or Auto. If the switch is in the Off position, the subwoofer will not power up. If the switch is in the On position, it will constantly remain on. When the switch is in the Auto position, when a signal is present the subwoofer will turn on and when will automatically turn off several minutes after a signal is no longer present.


Sub Input: This input is an RCA type mono input that will be hooked up to your receiver's subwoofer output.

High Level Input: These are spring post type speaker connectors. The high-level inputs are designed to be used with receiver or amplifiers that do no incorporate any RCA type subwoofer outputs.
