Customer Review

After considering all comments, and 2-in-one (free shipping), I took a couple of these. I checked the worn and sealed. When worn, you can use a hair dryer. They grow a lot of air! Also, go deep. I like the small size of the sealed box (an internal square feet) and have the power to drive them – if it is closed. You have the ability to damage things in the room above them. So far – a mirror, and a remote control. They work very well in aHouse or a car! They require more power than many speakers, I tried with the same note. Do not have much on this fib. One of them is as good as a subwoofer rsw10 home. I have one and gave back. Rip-off over $ 400. This, you feel your dollars are spent wisely. I was cautious 11 mm xmax (excursion), but many of her books!

Amazing – Kurt Niederluecke – Minnesota
Sound quality of these subwoofers is phenomenal. You may feel during the car. You are on the market for the top. 5 stars without doubt.

Should have been 12.1 not 12.1D – Peter R. Cooper – Los Angeles, CA USA

Acoustic Research Performance AR-S108PS – Subwoofer – 120 Watt – black Overviews

The AR-S108PS subwoofer adds punch to the Performance Series speakers. An eight inch long-throw, high excursion woofer provides for exceptional low bass response, and the built-in 120-watt rms amplifier delivers dynamic, high output low frequencies, regardless of receiver power. Built with a variable low frequency crossover, the AR-S108PS adjusts to seamlessly blend with the other speakers in the Performance Series line.

Acoustic Research Performance AR-S108PS – Subwoofer – 120 Watt – black Specifications

The S108PS Performance Series powered subwoofer from Acoustic Research fills out the low end of your audio system with deep, resonant bass–terrific for heightening musical realism and delivering the one-two punch of LFE (low-frequency effects) DVD soundtracks. The subwoofer pumps out 120 watts and uses a ported cabinet design for greater efficiency.

When used in conjunction with smaller, bookshelf-type speakers, the subwoofer extends system capability to full-range frequency response (as low as 35 Hz). With larger, floorstanding speakers, the sub helps shoulder the burden of reproducing low-frequency information, and its variable crossover lets you scale its output to cover only frequencies deeper than those most efficiently reproduced by your floorstanders in your room (rooms have a huge effect on audible bass response).

Performance Series subwoofers like the S108PS are ideal for generating the tight, visceral bass that is so vital to an enjoyable music playback or engaging home theater experience.

AudioSource PSW100 100 Watt 10-inch Powered Subwoofer Features

• Built-in 100 watt RMS internal amplifier

AudioSource PSW100 100 Watt 10-inch Powered Subwoofer Specifications

Just the thing for your burgeoning home theater or back-room listening system, AudioSource’s affordable PSW100 subwoofer pounds out 100 rock-solid watts of low-end power, bringing high-impact slam to DVDs and greater ambient detail and instrumental heft to your favorite music.

A variable low-pass filter (LPF) lets you tailor the sub’s output to your existing speakers. By setting the LPF high (toward 180 Hz) you can fill in the bass for bookshelf speakers that may have extremely limited bass output, while a lower setting (toward 40 Hz) will supplement and perceptually deepen the output from larger, floorstanding speakers that have more of their own low end to start with.

You’re getting more than just the basics here: the PSW100 comes with a phase-reverse switch for placement flexibility (to help align the crests and dips of the different sound waves when the PSW100 and your main speakers are in different places) and auto-on signal sensing for power conservation.

You can hook up the PSW100 one of 2 ways. In the first case, you can feed the sub an RCA-tipped line-level signal from your preamplifier or surround receiver. Using this method, your receiver can most effectively route the LFE (low-frequency effects) channel from Dolby Digital, DTS, DVD-Audio, or SACD surround programs directly to your subwoofer.

Alternately, you can run speaker cable from your receiver to the PSW100 and then from the sub’s outputs to your front left/right speakers. Use of this method results in a more seamless transition from the subwoofer to your speakers since the signal arriving at your speakers has already been filtered through the PSW100’s internal crossover (the variable LPF discussed above). If you plan to listen to stereo music with your subwoofer, this might be the way to go.

Customer Review

This makes the thunder in the table even rude. Be the creation of this attention, as pointed down and pick you if you met the speaker, if you're not careful.

It took a while 'to correct the sound. It was too messy, but simply by adjusting the distance between the walls and change the direction of the port to listen to resolve this problem. I would buy again.

Excellent purchase – Thomas R. Shannon –
This subwoofer offers an impressive amount of bass for a very reasonable price. Checks to make it easy to control the level. I can not I shake the whole house if I want, or turn it off and enjoy some 'subtle whisper beautiful, when it is too late for an earthquake. I recommend this sub for anyone.

Sounds good, but no auto-on signal sensing for power conservation – R. Brunner – San Francisco, CA
This subwoofer sound good, but not for self-detection of the signal – not in the field has always said, and draws ~ 15W when not in use continuously.

Monitor Audio Radius 720 RAD720SR Slim-Profile Powered Subwoofer (Single, Silver) Overviews

With the latest addition to the expanding Radius family, Monitor Audio demonstrates once again that you don’t need large, intrusive loudspeakers to bring true hi-fi performance to music and film. By any standards, the Radius 720 subwoofer is a remarkable design, which proves that diminutive dimensions and dynamite performance are not mutually exclusive.An evolution of the super-compact R360 subwoofer, it possesses the speed, subtlety and accuracy to enhance the highest quality music reproduction but delivers the power and slam demanded by movie soundtracks with an ease and authority unprecedented for its size. The R720’s twin downward-firing 8″ treated paper cone drivers are mounted within a ported enclosure and controlled by a powerful built-in 250 watt amplifier. Its versatile control settings make it the perfect partner for all Radius loudspeakers and ensure compatibility with most other speaker packages. Crossover control range is 40Hz -180Hz. Speaker level connections achieve optimum performance in a stereo audio system or in the absence of RCA outputs on the amplifier. RCA stereo inputs and an LFE input are provided for connection to a two-channel amplifier or multi-channel home cinema receiver. An auto function switches the R720 on when an input signal is detected. And switches it off after approximately 15 minutes if no input signal is detected. As with all Radius products, build quality and finish are of the highest order. The R720’s cabinet is constructed from heavy duty MDF throughout, lending a weight and solidity that belie its svelte dimensions. The real wood veneer, satin and lacquer finishes, aluminium back plate and smooth-acting, rubberised controls are all part of the quality-led approach that sets Radius apart.
