Consummate 10" 1950 Watt Paradigm Subwoofer Ultracube 10Consummate 10" 1950 Watt (Dynamic Peak) Paradigm Subwoofer in very good condition.
For its size, Paradigm's Ultracube 10 is hands down the best sounding subwoofer we have yet come across, rivaled only by a high end REL from a few years back.
Single high-excursion driver, dual 229-mm (9 in) balanced-plane, high-velocity passive radiators, built-in advanced Class-D™ amplifier. Power output is 1950 watts Dynamic Peak/650 watts RMS.

Retailed new for over $1500 with taxes. We normally list Paradigm's excellent Ultracube 10 for $895, but have discounted this one to $795, as it is just shy of our best rating at high volumes. (Still fantastic power and low frequency extension at low and moderate volumes.)

Impressive Tannoy Side-Firing Subwoofer in High Gloss WhiteImpressive Tannoy Side-Firing Subwoofer in High Gloss White
The TS 2.10 draws on Tannoy’s extensive professional and stadium loudspeaker design experience to deliver class-leading low frequency drama and thunderous bass effects. Designed to excel in speed and power, it uses a powerful digital amplifier and two large, long-throw drivers to output extremely fast and deep bass. The design allows considerable LFE output from a compact cabinet, making the TS2 range ideal for a wide range of home cinema systems.
It moves large amounts of air with ease, reproduces fast and lively rhythms with good detail and reaches down to a claimed 24Hz.
It certainly explores deeper basslines with confidence, filling the room in compelling fashion with music and films.
If you take the grilles off, you’ll see that it’s sporting two side-firing 25cm drivers – one is powered by a 300W Class D, while the other is a passive radiator.
The TS2.10 also has variable phase control, which, along with the standard complement of line-level inputs and outputs, is nice to find and makes it easier to integrate with an existing speaker package.
Excellent build and finish - The cabinet is built from heavyweight 25mm MDF, and sports a distinctive high-gloss white finish, well up to coffee-table standard (although we don’t recommend you use it as one).
It’s solidly built too, so nothing rattles when the going gets "explosiony". The TS2.10 is a fantastic subwoofer that delivers dynamic, engaging bass.

B&W 10" Active Subwoofer 280 Watts Peak ASW500Great Sounding B&W Bowers and Wilkins ASW 500 Active Powered Subwoofer
• Integration within a system is made easy with the provision of line or speaker level connections. Like other ASW subwoofers the ASW 500 is an active vented-box design using a 10-inch long-throw driver. Quality low bass is assured by Flowport™ technology.
• The ASW 500 can improve the power handling and sound of any system by reducing the demands on the existing amplification. It is an ideal choice for smaller rooms but where quality cannot be compromised and its versatility allows it to be used both in a Hi-Fi or AV set-up.
• Flowport™: Golf ball aerodynamics theory points the way towards lower distortion reflex ports. Dimples improve the way the air flows over the surface of any object. In the case of reflex ports, they offer a significant improvement over simply flaring the port ends in reducing air flow turbulence at each end of the port; so you get less chuffing noise and less compression at high sound levels.
Amplifier Power: 70 Watts RMS (Conservatively Rated), 280 Watts Peak. System Frequency Response: -3dB at 32Hz and 80Hz

Distinctive, Award-Winning Mission 8" Corner Subwoofer FS1Winner of the prestigious Innovations Design and Engineering Awards from the Consumer Electronics Association (CEA), The Mission FS1 Subwoofer is a compact corner mount design shaped like one-eighth of a sphere, ideal for use in small rooms where space is at a premium.
The stunningly designed, ultra-modern FS1 offers a high-technology, high-style alternative to traditional box-type home theatre speakers, and opens up a myriad of possibilities for apartment dwellers and homeowners who want to enjoy the complete home theatre experience in any size room.
The 8-inch treated paper cone woofer, built-in 100-watt amplifier, and reflex-tuned enclosure provide the clear, dynamic, articulate bass response necessary for enjoying a movie theatre-like experience at home. The unique subwoofer design is a further demonstration of the innovative engineering philosophy of the Mission fs Series concept. Rather than adopt a traditional cube subwoofer design, with its limited placement capability, the FS1 is designed to allow speaker placement in areas of the room traditionally considered to be ""dead space""--the corners. By engineering the enclosure to take advantage of both floor and wall boundaries, the subwoofer is able to deliver surprisingly powerful bass from a compact, space-saving design.

Great Sounding Compact B&W Subwoofer w/ 6.5" Woofer AS1Great Sounding Compact B&W Subwoofer with 6.5" Woofer
The AS1 subwoofer is an active, entry-level subwoofer equipped with an 85-watt amplifier. Bass extension passes through a 6.5-inch woofer with a frequency range of 27Hz to 100Hz and also has a selectable music/movie mode. The music/movie switch operates easily for precise presentation of material with a frequency response of 34-75Hz (music) and 27-75Hz (movie). This switch is a unique offering in a subwoofer, as is its location: conveniently, along with the volume level switch, on the top surface of the sub, other than on the rear panel where many other subwoofer brands offer their controls.
Many bass cabinets have "turbulence" in and out of the tuning port. The Flowport design uses golf ball aerodynamics to smooth the airflow and reduce acoustic interference. The AS1 has a fit, unobtrusive appearance and is offered in a contemporary silver finish with gray grille.

Attractive Athena 6.5" Subwoofer in Cherry Finish P1Attractive Athena 6.5" Active Subwoofer in Cherry Finish
The P1's distinctive form factor makes it an ideal platform for a center speaker. It boasts a 75 watt amp powering a 6 1/2-inch woofer in a front-ported enclosure and offers two pairs of speaker-level inputs and outputs (offering considerable wiring flexibility) and a line-level RCA input, should you opt for a subwoofer feed from your preamp or receiver.
On the front of the sub cabinet are the standard bass-level control and bass-range control to adjust frequency rolloff (continuously variable between 50 and 150 hertz), and a Blend switch that reverses polarity to help accommodate for different speaker locations and listening-room anomalies.
As this is a compact sub with a modestly powered and relatively small woofer, we'd recommend it for deployment in a small - medium sized room for use at low and moderate volumes.

Line-level and speaker-level inputs let you connect this subwoofer to virtually any audio system.
Radique's Take: This series of subwoofers from Sony is not particularly impressive to look at, lots of plastic in the construction etc. What *is* impressive is that they seem to have been built to last. Very low failure rate on them compared to even much higher end brands and models. If you're looking for decent sound quality at modest volumes, that should last a long time if treated well, then this Sony might be a great option for you.
